Re: New Gear Tooth?

Kitty liter is clay and a great insulator
The reason to toss it into the kitty litter is that way the Cast iron does not become brittle ( which it will do if chilled too fast)

Kitty litter or sand will give you the slow cooling desired

Re: Drilling holes at an angle

Short answer is No, It's one thing to burn through 1/2 " of steel , but the 30 degrees means the cut will vary in thickness from 1/2" to 1" and then back again that means the torch has to handle variations in thickness while moving (Variable heat requirements) and that usually means &...

Re: Allowing For Bending Radius Folding 3mm Small Aluminium Sheet

Pollysdad When bending metal, you follow the centere of the sheet , which is called "The Neutral Axis" in the bend, the inside of the material compresses and the outside stretches so a lot depends on the radius of the bend when doing forming. So do not use the outside or inside dimensions ...
