We like 1" square tubing for legs. To add an low cost leg leveler, a 7/16" nut welded into the end of the leg and 1 1/2" x 7/16" carriage bolt have been used on may of our shop built stands. |

We started with 3" channel welded to 3/16" x 1 1/2" flat stock to give stability and mass. Since a spinning pair of disks to hold the rubber mold, it seems like a good idea to make it heavy enough to keep it from dancing around the shop floor. The channel has the perfect angle on it's web to attach the legs. |

The head on this metal cutting band saw can be pivoted to make angle cuts. Here a brace used in the framework of the spin caster is being cut to 20 degrees. |

You can never have enough clamps. Here's a shot where the stand and top are about ready to be welded. |

Machining |
||
|
This piece started life as part of an aluminum drawer slide. Here a 3/16" slot is being milled to hold the motor straight. |
||
|
The hub is from a piece of 2" aluminum bar stock. We machined it, bored and cut threads to fit the motor. |
||
|
The hub is attached to the 1/2" x 11 1/2" aluminum plate. The photo on the right shows 3/8" threads being tapped. Keeping taps started straight can sometimes be a real issue. My tapping unit is an old drill press body that has a hand wheel attached to the top spindle and another hand wheel to lift the tap. The spring has been removed. It works on gravity. |
