I have a Delta 18-36 x series drum sander that I’m unable to adjust for smooth elevation movement. I’ve followed all the manual instructions with no success. So I’ve decided to reinvent the wheel so to speak. I’ve a few possible idea’s , maybe a chain and sprocket to replace the belt or maybe a piston set up . I was just throwing it out there for any input. Any ideas or suggestions welcome

I have one and my elevation wheel turns real smooth. What is yours doing, does it like jump, or hop or something and/when having to give it extra force? Maybe take the table off (just 4 bolts holding it) and see if you still have the problem. If so remove the timing belt and spin each threaded rod individually and see if one is binding. A bit of work I know but if you can identify the problem maybe fixing it would be easier then redesigning it.

Thanks for the input , I’ve taken the all the steps per the manual and then some. The gears at the main post ( front left) are not a very good fit from day one. I have done as you suggest, becoming very good at disassembly and assembly. yes the belt does bind and jump. Never was very smooth from day one. became worse when an adjustment was needed because of uneven sanding on wide material. Seems to me the drive gears should have been placed closer to the hand wheel since the shaft is undersized in my opinion.(to much flex) One time I was able to get smooth movement all four post were at different heights. I like a challenge so I’ll keep working on it. Thanks again.

When I first got mine and was setting it up my belt jumped too, but it was my fault. The idler pulley that tensions the belt was not adjusted properly and I didn’t know it allowing the belt to jump cogs on the pulleys. Since then when iI adjusted it, no problems.

Can the meshing of the gears be adjusted?

I’m going to take a closer look at the new ones and try them next time I’m at a store that has one on display.

Keep us posted with your progress, others may benefit.
