Update 1: fixed jaw files were not included, added now.
A project ive been working on for some time, the model 301 Tapping Arm is a mostly printed tool to help with tapping. For the past 8 months its been my entire tapping setup, replacing my case of taps and dies since i dont use dies. The tool is ideal for me as I dont like vises in my small workshop since they disrupt the edge of my bench and make it less useful (I have a vise in a separate room but moving is not ideal.)
Build guide:
This is a version 2, I never released version 1 which is shown above.
The tapping arm features a removable vise, two of them actually, to allow for any part to be quickly setup. I use the same standard as my fractal vise so all the jaws for that work on this as well.
Build guide coming soon!.
