First, order some urethane casting compound, for example, [http://www.mcmaster.com/#8644k11/=3f24h0 part #8644K11 from McMaster Carr]. This can be used to repair seals, make molds to cast ceramics, etc. It comes in two parts; you mix the two together, and then pour them into your mold. They take 48 hours to dry, and there is no baking required. | First, order some urethane casting compound, for example, [http://www.mcmaster.com/#8644k11/=3f24h0 part #8644K11 from McMaster Carr].

− | Molds can be made out of steel tubing -- you can use the steel tubing that will be housing the bushings; that will ensure that the bushings are the correct diameter. Bases can be turned out of HDPE plastic, so the tubing presses into it, and then you can drill a hole in the base for some 3/4" nylon rod used as a center | + | Molds can be made out of steel tubing -- you can use the steel tubing that will be housing the bushings; that will ensure that the bushings are the correct diameter.
