SDI Fastener Repair Lab assignment


you need to invest in some reverse twist bits too.


As a tool and die maker who gets “instructed” quite often on Youtube of which way the file cuts, i am here to pass on the same message - dragging the file backward will dull it, unless it is a diamond file.

And yes, iDrag… the file that is… sometimes… when i need to…


You making this post and me receiving an SDI advertisement from 1911forum made me go and finally look.

While browsing the site i felt really good about living in California.

I believe those classes are the finish an 80% lower. If I remember right, the options are AR15, AR10, and 1911. I’m kind leaning towards the 1911 option myself.

They send everything for the course, the 80% receiver, jig, drill bits. Every few weeks I get another package in the mail from them with tools and stuff.
