Pelham Waterford Bit
It uses a variety of pressures, which all in all seem to work together to prove a very useful bit. Basically the Pelham is an incorporation of the Weymouth and bradoon, and should theoretically be used with 2 reins. the first rein is attached to the snaffle rein, and the second rein attached to the ring at the bottom of the shank, when the first rein is used the Pelham acts like a hanging cheek snaffle, putting slight pressure on the poll and carious pressures in the mouth depending on the mouthpiece, when the second rein is brought into play, this increases the leverage and lip pressure, and also the curb chain comes into play. This bit has a chain type mouthpiece which has ball shaped links linked together, the bit is floppy and mobile in everyway, it is completely movable in all directions. The Waterford mouthpiece has proved one of the most popular bits for bitting problems such as leaning, taking hold of the bit, setting the jaw etc, when the horse tries to lean or take hold of the bit, the waterford mouthpiece collapses, thus the horse has nothing rigid to take hold of. It encourages the horse to work off their quarters and carry themselves rather than using the bit as a bike handle to lean on. This bit has several joints and distributes the pressure of the mouthpiece over both the tongue and bars. Although this bit may look severe it is quite a mild bit.
How to measure for a bit
A bit should fit your horse’s mouth so that the mouthpiece extends approximately 1/4 inch (0.6 cm) beyond the horse’s lips on either side, but not so tight that the horse might be pinched by any movable cheek pieces. You also don’t want a great length of bit hanging out of the horse’s mouth.
The different parts of the mouthpieces on bits are made to sit on specific areas of the mouth. So for the bit to be effective, the bit needs to contact those areas properly. You also don’t want the bit pulling through the horse’s mouth when you pull on a rein.
Measure an old bit you know already fits. Use a tape measure to measure from the inside of each cheek piece or ring.
Use a piece of string about 12” (30cm) long. Tie a knot about 2 inches (5cm) in. Put it through your horse’s mouth, with the knot against the lips on one side. Mark the opposite side with a marker or little piece of tape.
