I had some problems putting the threaded bolt end directly into the chuck, so I got a jam nut and a threaded connector to put on the threaded end and then into the chuck. Worked a bit better for me, and I didn’t damage the threads or the chuck. Your way probably works fine if you’re less of a klutz than I am!
I'm not so sure on that one lol! For the LIFE of me I couldn't find an 5/8 threaded connector! I looked and looked and I suppose HD was just out. I replaced the original bolt with a 3.5" one, kept the same square head, and added a lock washer to the base so I could get some purchase. To your point about the chuck slipping... I just ground the lower threads down on three sides to give the teeth something to clamp onto.
For all of ~$3 I reasoned that this was a one-job-only kinda tool... Link if anyone needs help finding a freeze plug https://www.homedepot.com/p/Oatey-1-1-2-in-Gripper-Plastic-Mechanical-Test-Plug-33400/100342630
I'm curious how you ran yours! - I've seen so many different designs with a drill, but nothing that let the shopsmith clean itself. I only have just the one, so I wanted to see if three way tubes kept enough stability to allow me to clean one pipe while the others were all locked in place. I scrounged around the shop and came up with an approximation of the extension table (2x4 and some dowel I had laying around) and some old skateboard wheels a neighbor threw away.
I was concerned about speed causing the pipe to simply hop out, so I went through a few tests and safety checks. After aligning everything, leveling the pipe, and setting the spacing to let the way tube get a bit of a draw from both wheels. I ran it with a few ratcheting tie-down straps to catch it if it decided to move. TBH I'm not sure if the whole was clever or stupid, but I felt pretty confident after my initial tests.
It worked out pretty well I'm pleased to say. Never even tried to jump, the only hiccup was the chuck loosened up and it started to push out on me... hence the grinding lol.
So far I've cleaned the lower two way tubes as good as I'm going to get without taking the top layer off and am considering seeing if I can flip the pairs for the last two cleanup. As I understand the upper tubes *are* shorter, but I wonder if it's got enough wiggle room to allow the trio cleanup again.
