Second attempt at a test stand using PVC plumbing parts-----This one WORKS....;)

Uprights are 1" PVC, and the cross-ties are 1/2" CPVC. The clamping widget uses bent washers to capture the tubes, but I'll probably make something a bit more elegant. In this setup, the pins for the springs are captured inside the PVC fittings. I think the opening are big enough for most springs, if that's ever needed. Another option is to cut notches in the PVC to grab the TT deck at the edge.

DUT is a Perpetuum Ebner----real problem child, but that's another story......;)

WOW Mark, very impressive! 8)

Especially coming from one who usually props up a turntable with four 4"x4"x4" wood blocks or four one-pound metal coffee cans. :lol:

Nice job Mark, now it just needs a 45 degree angle mirror with a light. :)

I haven't yet tried a mirror....it seems that it might cause some coordination issues. In thinking about the most comfortable way to work on these things, one idea was to do it lying on my back---maybe on an air mattress. In my case, that would not fit in my shop space. The current setup is pretty easy to work with....so far.

Cool idea. When I was working on an old 1951 turntable, I had it on boxes and soda cans also, so I came up with this idea. A ceiling hook my wife hung flowers from. Not a very good picture. I can sit in a chair and watch everything move and make adjustments. When I stand, it’s eye level. The spreader bar folds and all hangs in the shed. I got the idea from the owner of a Radio-TV shop that I worked at in the 60’s. It hung in the shop from the ceiling with ropes and a pulley. When done, just lower down onto the bench.

Now that is elegant simplicity!!

My only reservation with that approach is that it will move around a lot....and I assume it's a bit tricky to load records.

Ohhh. It's tricky alright. Those metal hooks were slipping and sliding all around until I put some electrical tape on them. Slow and easy works. I was real proud of myself when I first hung it up. Until I realized the 78's were hitting the chain. That's why the spreaders are there. Sprayed them white to give it a little class. Simple things make simple minds happy. Through life I have learned that there are plus's and minus's to everything. Your's looks as solid as a rock, BUT it looks like it would be hard watching the moment underneath. With mine, I can turn it around and see everything, BUT slow and easy or it may fall in your lap. I think we both came up with a cool idea though.
