Re: [CAD_CAM_EDM_DRO] Re: Alum. Extrusion Manufacturers

I'd never have them made. This ONLY gets to be a wonderful Idea if I (or any
hobbiest) can call Mcmaster (or someone else) and order a X' foot stick of
an extrusion that works well with this method. One can make a lot of parts
with 10 feet ! AND, this is super simple..........

Casting ?? My wife hates it when I convert the kitchen oven into something
for that use ! :-)
