Pinion and spur gear is a way of adding additional functionality to a rifle, typically by changing the length of the rifle’s action. These two components work in tandem to create different weapons: the spur gear allows for customization of the stock, while pinioning brings adjustable cheek and cheekbone position.
Spur gear was originally created as a way to add length to a rifle, making it longer or thicker at the end of the stock. This can help aid in range training, since you can now sit deeper in your seat while shooting.
Pinioning was originally created as a way to adjust cheek position on guns withacherhead, making it easier to look through the sight and get an accurate shot on target.

Set pinion depth
Once you have your pinion depth set, it is time to test it! You can do this by simply leaving a few inches between the pinion and the bottom of the spindle. Or you can put in some extra space!
If your spur gear setup works, then you will see a slight lifting of the spindle as the gear moves. This is normal and indicates that the setup works. If there is serious bind issues, this may not happen.
If there is more excess spur gear material above and below the engaged gear, then there may be an issue with overloading the gearing or breaking it.
Set spur angle
Now that you have your Pinion andenery, it is time to set the angle at which the spur contacts the horse’s leg. This angle can be changed via the pinion settings.
Usually, this setting is at 25–30 degrees, but there are some instructors who say 35–40 degrees is better. Either way, look for a setting that is close to your own leg length.
A longer leg will allow more space between horse and shoe, and a shorter one will give less space between shoe and leg.
Set spur height
When setting the spur height, you will want to know what you are trying to achieve. Say you are looking to steepen your stomache velvet. Then, say you are wanting to increase your gait. Then, say wanting a softer concave or flatter profile in your heels.
The easiest way to set the spur height is by placing a paper clip at one end, then pulling up with another paper clip at the other end. This will give you a little bit of resistance when trying to insert and remove the spur.
Once inserted, leave it there for about an hour before walking or riding so it can work through the heel bone and into the sole. Remove it and let it dry before using again.
There are many ways to get your horse set up with pins and glue-in spurs. Some use binder clips instead of sets of paper clips, or use rollers instead of just one piece of glue-in gear.
Make sure there is enough space for the gears to fit
There should be enough space for the gears to fit in. If there is not enough space, your horse will be nervous or uncomfortable, and they may have to wait longer to get back up.
The spur can only be used at a right angle, so it needs space for movement. The pinion can only turn clockwise or away from the horse, so it must have room for motion.
Making sure there is enough space between the two parts of the gear helps prevent any kind of pressure or interference when trying to put it on or take it off.
Make sure the gear does not hit the case or any other part
If the spur gear hits the case, it must be kept as short as possible. A short spur gear can hit the case at a slight angle, causing damage or pulling off of the case.
To keep a short spur gear, wrap some electrical tape around it and then place it in a metal case. If you are having trouble doing this, there are brands that sell these types of cases that you can purchase.
Then, make sure it is set in plate mode or leather mode to prevent pulling off of the board. In leather mode, make sure there are no sharp edges to prevent passing through the board. In plate mode, make sure nothing is sticking out that far to prevent breaking off.
Check clearances between the gear and shaft
When you remove your partner from a penetration, the two of you need to let the shaft dangle free to allow room for expansion and contraction.
Without being loaded, the shaft can be shaped by body contours and inserted with ease. Once it is in, it can only be withdrawn!
The Spur Gear is another piece of equipment that can affect clearances in subtle ways. When you remove your partner from a penetration, the Spur Gear can give you some relief! If it was inserted too deep or long, this may prevent removal or reinforcement of the female reproductive system.
A common way to check if the Spur Gear is affecting your clearances is to lightly touch a little flesh along the shaft where it joins the pelvis. If any slight resistance is felt, then it may be preventing easy removal or reduction of pressure on the part being penetrated.
