I have attached a few pics showing the upper wheel tensioning assembly for the new Rikon 10-345 18 inch bandsaw.
I had noticed that it is very difficult to tension/track the upper wheel with any repeatability at all. Rikon tech support has been very helpful, but, I believe they unlocked the mystery when they told me that the upper wheel tension/tracking assembly was redesigned.
I believe there is an absolute fatal flaw in the design from a mechanical standpoint. Look at the pictures below and let me know if you can see it. IMHO this design will NEVER deliver repeatable positioning as-is. If you see something and would like clarification just ask.
If any of you have the 10-340, which had the "old" design, I'd love to see some shots of the upper wheel tension assy for that model to compare.
The first picture shows the entire assembly. The second shows the top of the assembly. Note the slot in this surface.
The third shows a closeup where the tensioning wheel threaded shaft comes through the frame bottom. You can also see the curved surface of the tensioning arm end.
