I have decided to build my own jig for pressing the two lower rivets on a Yugo underfolder. Below you will find a photo of what I want to build. The problem is the link I found for the plans has some of the photos with measurements missing and I know I have seen a blue print for this type of jig somewhere before but after searching the web for two plus hours last night I give up.
My question is while what I have has some measurements, is there any reason why I can’t use a 1” ram and 1” ID tube to do this? I am sure I will have to also change the bolt used to make the arm since a ¾” bolt will be too big to use on the 1” ram. The reason is I have everything readily available to change it to 1” Any input is highly appreciated.
I tried several times to upload just the pics but no luck! Here is the link:
