I have an adjustable notcher but since these were all 90's, I just used the drill press. I also have a small belt sander with an upper roller that is just the right size for cleaning up 1.75" tubing. I actually broke the 3/8 stem off my holesaw arbor doing this and ended up finishing the last few with the lathe.

I didn't have to tap any holes since I started with a threaded coupler. Welding on a couple of nuts would work too.

It looks good!
