I haven't been on here for a while so I had to open a new account, couldn't remember my login
I just wanted to put this up to help some people out that may be looking for a easier way or a new idea. You will obviously see that I didn't invest a lot of time into it because I wasn't sure of the validity of my idea. . . .
My idea was to make a belt sander with inter-changeable drums to precision miter thin wall tubing (.028/.035/.7mm/.8mm etc) Instead I ended up making a attachment for my vertical mill. It took about a day to cobble this together and maybe $100 in materials.
When I turned the drums on the lathe I made provisions for a bearing to be installed at the end with a plan of using a piece to support the end and help the tool to take some load off of the mill spindle. However it works so effortlessly and I am using such a light belt tension that I don't think its that important (however I may still fab one because it really is the right way to do it)
I definitely need to make a support for the idler pulley side that I will have a micro adjust so that I can set belt tension and alignment in a more consistent and precise way.
After making this attachment I am surprised at how effortlessly it works, absolutely no chatter as compared to using hole saws or annular cutters that feel like they are fighting to get the job done. I wish I made this 5 years ago haha.
Anyway, maybe this is nothing new and you guys have been doing stuff like this for ever but I thought it might help some people looking for a better way . . .. tube mitering on a vertical mill - YouTube
