Application of Tungsten Pins

THERE ARE ANY NUMBER OF TRACTION DEVICES ON THE MARKET TODAY but a few of the most useful and least likely to create problems with the upper limb are the Tungsten pins, drive-in studs and nails with hard facing. All three are easily applied and provide significant security for horses that have to spend any time on blacktop, concrete or slippery rocks. One word of caution – always wear safety glasses when you are applying traction devices, as there is always a danger of your tool or the material chipping.

The V-Trak nails are simply applied by choosing the position where you wish to establish the traction (very often in the heel nail) and driving as you would any other nails. This is a very useful device when you have already shod a horse and find that it needs something to help give it confidence when loading or unloading in a trailer or on the show grounds where there is concrete or blacktop that has to be crossed. The nails are used extensively in the Standardbred market, particularly in the winter months.

Tungsten carbide pins are also easy to apply. They require a smaller drill bit than drive in studs (the fp brand works with a 4.5mm bit) and the 100% tungsten material provides just as much traction as the drive-in stud.

For either the pins or studs, you should first center punch the spot you plan to drill. This will help keep the bit from sliding out of position.

To avoid reaming the hole or distorting it, use a drill press or place your shoe in a vise to keep it secure. Once you have the hole drilled, place the pin in from the ground surface and tap into the depth you desire. Avoid bottoming out and making contact with the anvil face or flat surface you are using. The pins are tapered so they will tighten as you drive them in. It is also recommended to use a hammer that has a tempered face so that you don’t chip the tool. Another method of driving the pin into place is to flip it over once you have it started, and either on a metal plate or the chisel plate of your anvil, hit the foot surface of the shoe with your hammer until the pin has seated.

The drive-in studs are applied in exactly the same manner as the tungsten pins. Again, use caution when applying and don’t bottom out. The fp brand studs require a 17/64” drill bit.

Typical applications might be a pin or stud in each heel – approximately half way between the end of the shoe and the end of the crease (or last nail hole). This allows the heel landing to still have a slight bit of slide before the traction kicks in. In the toe area it is typical to see the pins or studs placed just in front of the end of the crease. You will have to make your own judgment as to whether you need something in the toe and heel area. Just keep in mind that too much traction may be counterproductive and create soreness or lameness.

Clipping Methods by Roy Bloom, CJF APF-I

Volume 3, Issue 1 of The Natural Angle featured a story on clipping shoes using the edge of the anvil. In the step by step discussion in that article we used a clipping hammer, which is similar to a ball pein. In this article, the photos show the clipping process with the clipping, rounding and cross pein hammers as well as a handled bob punch. As you can see from the photos, the three hammers are used in an identical manner. The starting of the bubble using the bob punch is different but the drawing of the clip is the same. The point of this article is to illustrate the fact that the clips you end up with can be very similar- making it a matter of personal preference as to which tool you use to start your clips.

The hammers all require good control to produce a consistent bubble. The bob punch is somewhat easier to control but you have to be cautious not to drive the punch too deep as you may pierce the shoe. The bubble is not always as easy to draw but with practice it can provide a very consistent clip and may help avoid distortion to your crease and nail holes if your hammer control is not just right in the bubble step.

No matter how you start the bubble you need good hammer control when you are drawing the clips. Also keep in mind if you don’t use the edges of your hammer or anvil you will end up with clips that look like toe caps.


Photo 1. Use the tool that works best for you.


Photo 2. Establish a good balanced position for starting your clips using the various hammers.


Photos 3, 4. With each of the hammers, you want to drive the hammer at a 45 degree angle,
directly at the edge of the anvil.


Photos 5, 6, 7. No matter which hammer you choose,
you have to have good control to establish a good start to the clip.


Photo 8. The bob-punch requires a different starting method. Start first by setting the point of contact.


Photos 9, 10. You then slide to the edge of the hardy hole to finish producing the bubble.
Be careful not to drive the punch too deep as it can easily pierce the shoe and leave a hole.
As you can see the bubble is slightly different from the one produced by the hammers.


Photo 11. This is the bubble produced by the hammers, you should flatten the area behind the clip
with the clip toward you and using the heel area of the hammer.
This makes it much easier to see your work.


Photos 12, 13, 14. I like to draw the clips working from the same end of the anvil.
This gives me clearance for the tongs as I rotate the shoe during the drawing of the clip.
In this case I am using the flat of the hammer and the edge of the anvil to draw the clip.


Photo 15. Use the corners of the hardy hole to set your clip base.


Photos 16, 17, 18, 19. You can see that you can get similar results no matter which tool you choose.
The key to consistency is practice and hammer control. The method I use for the hammers, working from the end of the anvil, gives me a nicely balanced position where I can get good control of my hammer and the tongs.


Photo 20. The goal is consistently strong clips no matter what method you use.

12 Points of Reference: The Knee

By Dave Farley, CF APF-I and Roy Bloom, CJF APF-I

The 12 Points of Reference article previously printed in the Natural Angle Volume 12, Issue 1, combined with the 12 points DVD “is a winning combination.” We both use these steps on every horse we trim. Each of the 12 points can be linked to each other. We have all heard the statement, “Every action has a reaction.” This is a very important statement when compared to the bones and joints in the lower limb of every animal we trim. Each digit of the lower limb could be normal for that particular equine. Likewise, there are several abnormal conformation faults possible for each digit in the lower limb of any horse. The more normal the conformation the easier to trim and shoe, if we pay attention and keep the limb balanced for that animal. The more deviation or abnormal the conformation of each bone and joint in the limb, the more important it is to properly trim and maintain that limb for the longevity of that animal.

PHOTO (RIGHT): Knees are turned out, however the foot is trying to be straight. This has resulted in a twist of the pastern and places the entire leg inside of center.

As you learn each of the 12 points, you will think of a particular animal you work on and start to wonder if you have done the best trim that you can. Proper trimming will improve the health of the limb as well as the health of the horse. If you improve the trim you will also improve the ability of that animal. If you improve the ability you will have a happy horse and a happy owner. Remember, every action has a reaction!

The first point of reference is the knee. We mentioned that the knee dictates the direction of breakover of that limb. As with each of the 12 points, we believe it is important to observe the horse at the walk as well as standing. Watch the limb as the horse walks toward you. Notice the action of the front limbs. Where is the knee in relation to the rest of the limb? Is the knee in the center of the limb (normal); as the horse moves, the knee breaks straight without the limb swinging in or out? Is it base narrow; toed out, as the knee breaks, the limb moves inward toward the center of the body, and the hoof swings toward the opposite leg? Is it base wide; toed in and as the limb breaks over it rotates out and the hoof wings outwards? After the horse is standing, we like to walk around the animal. Is the knee flat (normal) or is it angled out (base narrow) or angled in (base wide)? While this may seem a little confusing at first, a really cool thing will start to happen! After you watch a few horses move, and focus on the knee you will be able to predict the conformation of the rest of the limb before the animal gets closer to you. You will also be able to predict the wear on the hoof or shoe before you pick up a leg!

PHOTOS (ABOVE): Knees are turned out, feet follow knees and are turned out, leg is centered under knee and above foot.

Avoid Unnecessary Damage to Your Nail Puller

A significant number of crease nail pullers are returned to suppliers each year because of damage that can be avoided – not as a result of defective material or workmanship.

It is possible for heat treatment or defective metal to be a problem but be sure you used your tool correctly before returning it. Be sure that you cut or rasp the clinches off before trying to pull the nails. Start the tool opened as wide as possible to allow the points to penetrate any dirt or debris in the crease and get under the nail head. The nail puller has to get under the head of the nail to work properly. If you only have contact with the tips of the tool and then squeeze and try to pull the nail without first lifting it you are asking for trouble. (Photo 6 shows damaged tip of nail puller, likely a result of trying to pull the nail before getting the puller tips completely under the nail head. Notice the other puller has no damage and has been used much longer, but more correctly.)

Photo 1 – Start with wide opening.

Once you are under the head, a steady squeezing pressure should pop the nail loose. You can often hear the nail break loose from the crease. You will see that the nail head is fit snugly into the cavity of the pullers if you have used the tool correctly. When the head is in this cavity, the pressure of the rolling motion you use to pull the nail will not cause damage to the tool.

Photo 2 – Puller tips are not under nail head; this method causes damage to tool.

From time to time you may want to touch up the nail puller tips so they can penetrate the debris in the crease and get under the nail head. You should also be sure the tool is not too thick to fit into the crease. If it appears to be too thick you can use a belt sander to dress them to a thickness that works. Be careful not to grind too aggressively or for too long. You don’t want heat to build up and destroy the heat treat. If you can’t hold the tool because of the heat or it develops a blue color– it’s too hot. Quench it occasionally as you go through this grinding process.

Fullering Technique: Crossover or Inline?

Roy Bloom talked with us about fullering or creasing styles in forging or modifying shoes. This conversation was precipitated by some steel handled tools that were damaged and returned for inspection. It has also been a topic in Roy’s clinics for many years and it is certainly debatable as to which of the two common fullering techniques may work better for you.

Crossover

We’re going to use the terms “Crossover” and “Inline” to describe the two most common styles Roy discussed. We termed Crossover to mean the fullering tool is positioned on he branch of the shoe that is furthest from the hammer hand; in effect, crossing over one branch of the shoe to fuller the other. Inline fullering would be the opposite; positioning the fullering tool on the branch nearest the hammer hand. The decision on style used will dictate what fuller you buy – regardless of the marking of left or right on the tools. Keep that in mind when you shop for a fuller – especially steel handled.

Inline

We asked a number of top competitors why they worked predominantly with one style or the other. It wasn’t too surprising to hear that it all depended on how they were taught; whether it was in shoeing school or in following mentors or clinicians like so many things we do in work and life in general.

It is also clear, with a lot of practice and development of hand-eye coordination either style can work very well.

We have attended a lot of forging competitions and know that many of the top competitors use a Crossover style rather than the Inline.They have spent thousands of hours working on their skills and hand-eye coordination to reach the top levels and if they had any difficulty in the beginning, hard work and experience obviously got them past it.

Four tools all used in Crossover style. Two tools used by right hander, two by left hander.

If you look carefully you can see all were struck off center.

Left hander used this in Crossover style. Note damage to fuller end.

Roy talked about two key disadvantages of using the Crossover style for someone just starting in forging. The steel handled tools pictured in this article were all used by novice level farriers working in the Crossover style. This style requires an extremely skilled level of hammer control to be certain you are striking the center of the tool. The tendency is to lean the tool away from you and that forces the hammer swing to come from a less balanced position, with the elbow further away from the body. Your swing has to take the hammer in an arc that is not easy to gauge when starting out. Not to say that you won’t learn to compensate as you develop your hand-eye coordination, but in the early stages, this is a complicating factor and the reason why you see the damage to these steel handle tools. They have been struck on one side of the tool, not in the center. And it is always the side of the tool nearest your body. The more serious damage is what then happens to the working end of the tool as you can see with the deformation of the end of the fullers.

ABOVE: Left and Right Hand Crossover Style. Look closely at the position of the elbows in relation to the body.

The reduced control of the hammer swing is probably the primary drawback for using the Crossover style in your early stages of forging. Second to that is the reduction of power or force that occurs when the struck tool is further away from your body and your hammer arm is also not centered with the blow. Note the position of both elbows in the various pictures of the two styles. As a rule, the Inline style keeping the elbows closer to your center will maximize the control and power behind the hammer blow. This is just food for thought. If you are experiencing any difficulties keeping your struck tools in good shape, you may want to consider these ideas.

BELOW: Left and Right Hand Inline Style. Look closely at the position of the elbows in relation to the body.

What Kind of View Do You Have?

By David Farley

One of the steps to getting a good trim is often overlooked. If you don’t have a good view of the balance of the bottom of the foot it is difficult to get the best trim. How you hold the leg affects the view of the foot, sometimes dramatically changing the perception you end up with.

Many farriers have found that holding the leg in its most natural position is the best way to get a true picture of the balance. This applies to front or hind. Take a look at the pictures. Try holding the leg in the various positions. You may be surprised at the differences in what you might have done with the foot trim based on how you see the hoof
in these positions.

If you hold the front foot similar to photos 1 and 2 you are very likely getting a distorted view. Your hand, especially the thumb pressure, will push the hoof capsule in one direction or another. Holding the leg out from the body, as in photos 3, 4 and 5 will also create a distorted view.

Try holding the leg by the cannon bone and staying in line with the body. The hoof may be under the horse and you will have to crouch to get the view but it gives you the most accurate view of how the hoof aligns with the cannon bone and gives you a much better starting point for your trim. See photos 6, 7 and 8.

The hind view is similarly affected by not allowing the limb to hang as freely and near its natural position as possible. Pushing the leg out of position with your inside knee will make it difficult to see the true alignment of the hoof capsule to the leg. This is evident in photo 9.

Hold the leg under the hock joint and keep the cannon bone perpendicular to the ground as it is shown in photos 10 and 11. If the cannon bone is pulled forward or pushed back as it is in photos 12 and 13 it will distort your view – particularly of the toe and heel length.


Your trim should always be done with the alignment of the hoof capsule to the leg in mind. Hopefully these tips will help you to improve the view and the trim.

Building Efficiency With Equipment Adds Profit

No matter what business you are in, building efficiency into your operation is a key to making more profit in less time. A shoeing business is no different from a manufacturing or distribution business. You need to look for equipment that helps minimize your labor and time spent in getting to the final product, the finished shoeing job.

There are a number of power tools and other pieces of equipment that can be worked into your rig setup that will help with everyday steps in shoeing. A propane forge is the most obvious. The ability to heat your shoes will make the shaping and modification steps much easier. Everyone runs into feet that are in such bad shape that simply punching additional nail holes will make an otherwise difficult situation easier to handle. This doesn’t require a large forge but can be done with some of the single burner units. Mounting the forge on a swing out arm or slide out will help get the heat away from the rig and more accessible for your forging steps.

A lot of horseshoers are finding a belt sander/grinder combo to be an extremely useful piece of equipment. The belt sander is more versatile than a grinding wheel as you can select coarse grit belts (24 or 36 grit) for heavy grinding and finishing of steel and aluminum shoes. A quick change to finer grits like 80 or 120 and you will have the ideal setup for maintenance of your tools. You can even cut fine belts to a narrow width and use them for sharpening knives. If you have room for a buffer you can mount various buffing wheels, like sisal, felt or Scotch-Brite® to use for final honing of your knives or cleanup of nippers, punches and other hand tools.

If you already have a grinder but it doesn’t have the belt sander you can buy an attachment like the FootPro attachment arm and mount it. They are available in a 2”x36″ or 2”x48” belt option. They are compact and have a 8” rubber drive/contact wheel that creates great belt speed and makes working shoes and tools very easy. These attachments work well on 1/2 hp or larger grinders. Expander wheels are another good option if you are primarily grinding shoes.

Don’t look merely at price when you buy equipment like grinders. You are making an investment and want to maximize your return. Buy brands like Baldor, Jet or Kalamazoo in order to get the most life from the unit. One of the easiest ways to compare quality is to check the weight of the units. A 1/2 horsepower unit that weighs 20 lbs. will not have the “guts” of one that weighs 35-40 lbs and will not perform as well or last as long.

If you are doing a lot of work with hunters and jumpers you will have to drill and tap for studs. For pleasure horses the drive in studs are excellent traction devices but require holes to be drilled. Setting up a small drill press will make these jobs much easier, with less broken drill bits and less effort. A drill press will also make the job of riveting pads an easy task.

Remember the key phrase – time is money. If you consider the time spent using inefficient tools or methods to get your work done you will see that the investment in a few key pieces of equipment will add significant profit to your bottom line.

Therapeutic Case Provides Valuable Lessons for Students at Pacific Coast Horseshoeing School

by Larkin Greene

Recently, I spent time at Pacific Coast Horseshoeing School.  Students in their third week of instruction were able to observe and participate in valuable lessons regarding work with therapeutic cases.  I was privileged to help provide training and guidance for the treatment of the horse presented in the following photos.

Upon first glance at the foot shown below, it would be easy to look at the length and believe a proper course of action would be an aggressive trim, to find the better foot within.  However, this horse was older and had very limited mobility, underrun heels and an atrophied frog.  In addition, there was a significant white line resection and treatment done two months ago that was showing improvement.  The students performed a conservative trim to align the pastern and dorsal wall and shod the foot for protection.

The question of whether or not to repair was discussed.  There are many factors to be considered in this decision: (1) how much wall has been removed, and will it destabilize the capsule and P3?; (2) is there still wall separation, and/or pathology present?; (3) will the shoe stay on if it’s left open?; (4) is the horse’s environment going to contribute to further intrusion by bacteria and fungus?

The decision was made to do a partial repair to stabilize the hoof and protect it from a dirty environment. Because there was a soft spot in the upper portion of the defect that got a negative reaction to applied pressure, the conservative approach dictated leaving it open to allow monitoring and further treatment if needed.

Best Practices and Results for Application of Vettec Adhesives

by Larkin Greene

The increased moisture and lower temperatures associated with Winter and Spring present significant challenges to successful adhesive applications.  Adhesives prefer warm and dry, along with clean. Anyone who regularly picks up a horse’s foot knows that none of those characteristics happen without effort.

Larkin Greene demonstrates application of SuperFast to create a shoe for hoof wall protection.

The Effects of Cold
Vettec products perform optimally when used between 60 and 80F, in other words, room temperature.  When temperatures fall below that optimum range, adhesives become more viscous, harder to dispense, and take longer to set.  Both methacrylates and urethanes produce an exothermic cycle that is critical to their final set.  Colder temperatures inhibit that heat cycle; if the adhesive cannot generate that heat, the set will be softer, and the bond less reliable.  While many users are familiar with the need to warm up the adhesive, it’s also important to warm any surface it touches, including mix tips, any glued-on device, and especially, the surface of the foot itself.  If you forget to warm a surface, applying heat after the adhesive is on the foot can help, but does not guarantee success because the exothermic cycle is a chemical reaction formulated into the adhesive.  For temperatures below freezing, a heated workspace is essential to achieving predictable results.

Vettec SuperFast

Keeping materials warm is easy enough; most keep them in the cab of the truck, in an insulated container, or home-made hot box that contains a light bulb or warming pads.  The worst thing one can do is store them in the rig in cold weather, then try to warm them up prior to using them.  It takes time to warm up cold material, and it is best done slowly.  It’s easy to heat up the plastic cartridge, but it takes a while for warmth to penetrate throughout the material inside the cartridge.  Best practices would dictate not letting the material get cold in the first place; however, if quick warming is necessary, putting cartridges on the dashboard with the defroster running works well, or perhaps on the floorboards with the heater on.  Some have even reported success putting them in the engine compartment for a while after arriving at the barn.

Within the preferred temperature range, SuperFast sets in 30 seconds for non-weight bearing applications, and requires a minimum of 2.5 minutes before bearing weight on bottom applications.  Adhere sets in 45-60 seconds for non-weight bearing applications, and needs 3.5 minutes minimum before bearing weight in direct glue-on applications, five minutes would be better.

Any time adhesive products are used, it’s strongly recommended to make sure the hoof is as dry as possible. This handy moisture meter gives you a very accurate check of the moisture level. (shoot for less than 10%).

The Effects of Excess Moisture
Excessive moisture is the most common cause of adhesive failure in equine applications.  The inability to get the foot dry enough remains a challenge for many hoof care practitioners.  Fortunately, there are tools and techniques that allow us to conquer this problem.  Some methods work better than others. For example, a hair dryer is louder and less effective at drying a surface than a heat gun.  A heat gun is much quieter and more effective, held a few inches away, and kept in motion.  Another tool equal to or superior to a heat gun, is a hand-held propane torch with a soft flame.  The torch has the advantage of not requiring power, is also quiet, and produces great results if the same technique is applied: inches away and in constant motion.

Adding a moisture meter to your adhesive tool box is the best way to know that surfaces are actually dry enough for bonding.  Typically, the moisture meter must read below 10% for successful bonding, though single digits is desirable, and very attainable.  Once the foot surface is dry enough, the adhesive should be introduced in as short a time as possible for best results.

Effects of Excess Moisture After Bonding
If all protocols for proper bonding are followed at the time of application, excess moisture afterward is less detrimental, but can still lead to failure.  We know that horse’s feet swell when the ground is wet, and shrink when it dries out.  If that change happens during the weeks when an adhesive is in place, you can expect it to be a contributing factor in the failure of that application.  Frequent sessions at the wash rack, standing in an irrigated pasture, muddy paddock, or any other saturation conditions can contribute to shorter longevity, or early failure.  No bond can withstand immersion for any length of time beyond passing through a creek.

Following these guidelines for storage and handling of adhesives can dramatically improve success rates, and reduce the level of frustration users often experience when weather turns cold and wet.
