I first started with solid precision ground steel connector rods and after they worked so well I got the bench and way tubes also. I was upgrading from original Greenie bases to the double tilt so I had to get different tubes anyway. I went with the 1/4" walled tubes for the way tubes because I thought it would get too heavy to lift to the drill press position. That was a mistake because I also eventually got a lift assist and the solid steel tubes would have been no problem. After all the work I think it made a big difference. It added about 100 pounds to the Shopsmith and I have not had to do any alignments since. When I set up in the table saw mode I can depend on the fence, blade and miter slots to be aligned whether the fence is on the main table or one of the floating or end tables. And the connector rods always align with the 2 end tables I have on both sides of the main table, something I never was able to do before. Stability is great. I balanced a dime and a nickle on the main table and started to run the motor up from 500 RPM. The dime fell over when I got to 3,000 RPM and the nickle was still standing at 10,000 RPM.
Thanks. I found your post (https://shopsmith.com/ss_forum/maintenance-and-repair-f10/510-520-table-connector-tube-length-t19880-s10.html
) from 2017 where you talked about the solid connector tubes. I guess I would have thought over the short distance these are used that a hollow tube would have been rigid enough for connecting main table to aux table, but if your alignment improved after upgrading to these, I should consider it. For the waytubes, you say you got 1/4" thick tubing. Do you remember the supplier you got these from? Or does anyone else have recommended suppliers for thick wall tubing for way/bench tube replacements?
