Perfect The 1st Time.
"Easy Jig" is an appropriate name! It's clear that all of it's appointments are well thought out, no doubt by much trial & error. The instructions are clear and easy to follow. My 1st lower came out perfect! Never having milled anything before.
I'd love to add a photo of the awesome kryptic typhoon ceramicoat finish I had it done in, but Imac's instructions aren't nearly as clear as 80% Arms!
