Hello All,
Here is my Saturday project. I saw a picture on line and had to have one. It is incredibly ridged. Each component was fairly simple to make. I started with the main structure, ( drawing this part was a little time consuming) it's made of (.750) - 6061 aluminum. Next I made the swivel blocks out of (1.0) round stock. I drilled the through hole (.191), and turned each to (.750 OD). I added about (.750) extra material length to hold onto in the vise. Then I programmed the (.750) arc cut out. The top swivel clamp was machined from (.500) - 6061. I cheated on the slit. After the part was machined and drilled, I clamped it into the vise and cut it on my band saw. The two pins were turned from (.500) CRS, one was drilled through (.159) and tapped for 10-32, and the other was drilled through (.191) and c-bored (.250 ID). I turned one of the 10-32 SCS heads down to (.240 OD) and shortened the head length to (.185). The stop rod was a shaft I salvaged from a copier machine.
This was a very good project to break my new Taig mill in with, and I now have a good quality accessory for it.
Hope you enjoy it.
