Homemade version of Ideal Cylindrical Adjustable Mould

[Danny Ross]

I just use regular old 1-1/2” X 1/4” cold rolled steel for my sprue plates. Skim cut each side on the mill and drill the holes. Use an 82* countersink for the the actual sprue hole, wet sand with WD40 or cutting oil on a flat surface and you got it. Steel is much harder than lead, and I’ve never had one wear out.

I'm sure you are correct. I forget why I went with the saw blades. It's been a while.

I wasn’t trying to be critical, and one is really probably just as much work as the other. I do like the puddle it leaves on the thicker plates though.

Actually in looking closer at the mold, the saw blade makes more sense because of the venting. The thicker sprue plate wouldn’t really allow that. The sprue would be larger than the mold cavity.
