Topic tags/keywords: question

I know this machine has been the subject of several postings in the past. My question is… Does anyone have any experience changing out the rubber toothed timing belt that raises the table with a chain and sprocket configuration? I can sort of make the rubber belt work but only with a lot of tuning up work, usually when I am in the middle of a project. A chain drive system seems like it would be a better option and likely someone has done it already.

Sorry, Paul, I can’t be of any help on this one.

My home made one is manual feed.

I haven’t done that, but when I bought mine used, it needed to have the timing belt adjusted. I don’t know if I damaged it while moving it or if it was bad when I bought it. Anyhow, I took it to a Delta repair center and they had a difficult time getting it into proper adjustment. My point is that messing with this mechanism isn’t for the faint of heart. Good luck if you decide to tackle this adventure.

I had one of these for about 13 years, bought second hand and never heard anyone mention they had done that. I suppose it’s possible, but a huge amount of effort. The little plastic gears aren’t available anymore (someone, somewhere, did find a work around) so your idea would have merit for all the owners who may run into that problem.

Paul, I haven’t done what you’re thinking of, but I have replaced the nylon bevel gears and cleaned/lubricated the post mechanism so I’ve had all that apart. I operate the mechanism ginegerly because I regard it as fragile and prone to breaking again. I just wanted to say I think you’ve got a good idea and I’m interested in whatever plan and lessons learned you come away with.

My perception is that the toothed belt and cogs that it ride on isn’t the delicate part as much as the bevel gears that turn the force 90 degrees from the handle shaft to the first post. Were you planning on replacing those with something else at the same time? I guess I believe that only because when I bought my machine used for $70 it was because the nylon bevel gears were stripped out. They are available here if anyone else needs them.

I’d like to have a frank discussion with the designer that decided to save a few bucks and make all that out of plastic.

One goofy thing about the design is that the posts are not held in a defined vertical orientation. They are in ball gimbals so they can point whatever way they need to to be pointed at the holes in the table. The table isn’t in a defined X-Y position over the posts, it floats around over the frame. Why didn’t they have the table ride up and down on slides or posts that would define where the table would sit? When I look at my machine the posts aren’t very close to vertical. 4-5 degrees off vertical maybe.

Thanks for the comments, I agree that the design of this machine is shabby at best (Delta should be ashamed). I had hoped someone would have a solution that I could follow. My machine was also bought used and I don’t have a big investment in it so maybe (maybe) someday I will just replace it with a better brand but I will know what to look for in a lift system. As bad as it is it is still a machine that I use for most every project, don’t know what I would do without a drum sander. I’ve bookmarked your gear reference.
