Oscillating Sander Project.

Post by thegallery » Mon Jan 02, 2012 3:00 pm

I am finally getting back to work on my oscillating sander project. I need to finish the frame work for the work tables and get a 1/3 hp motor and mount to the oscillating gear box drive. I will use 3/4 inch hardwood for the work tables. It will soon be ready to be disassembled for paint. I have tested the oscillation with an electric drill and was very satisfied with the results.

Spec are:

3 x 80 inch belt
5/8 inch stroke on the oscillation
35 oscillations per minute
3/4 hp Baldor 1725 rpm drive motor
spindle sand above the the drive wheel on the drive motor
table tilts up 20 degree and down 45 degrees.

I will post pictures of the completed unit when paint and final assembly is finished.

Holy Cow. That's the mother of all oscillating sanders. That's amazing. I hope the dust collection is as impressive as the rest of the tool. Are you going to have T-slots for jigs? I have a little Ridgid sander which is extremely useful. It's especially good for thicknessing small wooden parts.

I was just going to put in a series of threaded inserts into the work top to hold jigs but I like you idea better. Those aluminum T slot dadoed into the wood top should do the trick. Thanks for the input.

Very nice work. Something I've been thinking of making for a while now.
3 x 80 doesn't sound like a common belt size, are you gong to make your own?
Would sure like to see a closeup of the tension / tracking end.

Thanks for sharing.
Greg

Greg, 3 x 80 is not a common belt. I did not want to go longer because I did not have the need or the space in my small shop. I believe I got the belt at McMaster-Carr here in Atlanta. I finished the frame work for the work table so I will include a picture along with several of the adjustment head.

Impressive! If you decide to release the plans, I would love to have a set!

I am sorry I am one of those nerdy machinist that build things with the plans as an image in my brain.

Hmm ... if you are interested in having plans (for example, to develop a magazine article or such), take extensive pictures and detailed measurements, and I'll draw up a set.

I should show you my thicknessing jig. It's truly pathetic, but it works absolutely perfectly. With your skills you could come up with a version which would be a whole lot slicker. It's just a vertical piece of MDF glued to a stick. You clamp both ends of the stick to the table and adjust the distance between the belt and MDF. You shove the wood against the belt movement, and the belt takes of a tiny layer on each pass.

I don't know if you've looked at a Ridgid oscillating sander, but everyone loves them, and you might steal some ideas.

It is finally ready for disassembly, paint, reassembly, and wiring. Test runs went very well. I will post the final picture next week.
