This will give you approximately 2-gallons of the 5% Albon (RX) for only $75 rather than only 1-pint that a Vet will sell you for $75 -- you figure up the savings! Once you have this 5% Albon solution mix, each teaspoonful (5 mL) will contain 250 mg of Sulfadimethoxine.
A low carbon mild steel designated A-36 is used for the most popular type of horseshoe. The steel comes in the form of round bars ranging from 0.5-0.7 in (1.27-1.8 cm) in diameter, depending on the type of shoe to be made. These bars are then cut to various lengths, again depending on the shoe type.
The picture below shows the type of horseshoe court I typically use. It is relatively simple to manufacture and is quite durable. The nice thing about this design is because the stake is not mounted in cement the stake will absorb some of the shock of the horseshoe. Allows your horseshoes to last longer, less bounce-offs and typically less noise.
