Title: Auto advance unit nut/bolt
Post by: Marqs1979 on 28.01. 2014 17:48

Hello!

This is the nut to the auto advance unit. I thought about making some new ones because my hex is destroyed. Can anyone tell me what the key width should be?

If you're making it, it's your choice!

I think it's 5/16" WW.

These are available to buy. The chap who refurbs A/R units sells them, seen them at Stafford show.

I did five pieces in stainless steel, some day someone might need one.

I want to make washers but unfortunately, I have nothing original to copy: (I've just realized that it will be an open washer there. But I guess it should fit quite right in the inner tray? How thick should it be?
