Title: De-oscillating the Ridgid sander
Post by: knuklhed on June 12, 2019, 05:21:52 PM
I know somebody has done it, I can't find the thread, though. Anybody got any tips on doing it? What to watch for, and how long to make the spacer? Thanks for any help!

There was a youtube on it.
Are you trying to make a pattern sander?

I think goobersan did that.

Thanks to you both, I'll search YouTube, and search Goobersan's posts.

I don’t know about the rigid sander but on my triton I had to take out one of the two belts (the oscillating one)

Send me your address Roger. I'll mail you a part to try

Josh, thanks for the kind offer. But, just the dimensions would be ok, I've got the ability to make the parts from a wide selection of engineering plastics. I will take pictures and post a build along for others who may also want to convert the sander. I'm going to make the 2" spindle into a pattern sander, as I have a bunch of 2" x 2" sleeves available.

I used polypropylene pipe
1-1/4" id
1-5/8" od (could be larger)
1-3/16" long was too short, add 3/16" to 4/16" as I had nearly 1/4" oscillation. Roy has the final video on his utub page. Pics are on page 43 of "2019 what did ya do today"

No way to eliminate all the vertical movement?

I believe there is.  Just needs a longer piece of pipe (3/16"-1/4" more)

A 2" pattern sander will not work very well.
This has a 24" belt and wont clog as often.

Max, now you got me thinking in a different direction.  (I may still take the oscillation out for general sanding, though.) Is that the belt attachment from the Ridgid? Having it do double duty is a great idea.

Mine works really good.

I found a video awhile back that showed how to use an oscillating spindle as a pattern sander.  Basically, the spindle floated on top of a bearing that never left the surface of the template.  I found it easier to make a pattern sander out of an old homemade drum sander motor and spindle mounted under a router table insert.  There's a line of spindles at Stewmac.com that have bearings attached.  It's designed to go into a drill press and is used for making guitars, but I switched the bearing from the top to the bottom, and it works pretty good that way.

I copied Max's idea, after having made a sleeve that stopped the oscillation, then removed it. I started out 1 1/2" high, then cut down to 1 1/4", which stopped it all, and left the belt just proud of the table. If anybody wants the sleeve, pm me, and I'll send it to you. The only thing I added to the max design was a bearing at the bottom of my plate, to make sure I was not side loading the drill press spindle too much. The tracking is taking a while to settle in, as I threw on a new 50 grit belt. My scrap of aluminum was not big or thick enough, so I had to add a rest out of Delrin to bring it to the right height (my patterns should slide well). Mike, I'll have to visit Stewmac, and bookmark it just in case. thanks

Yea on mine, the second picture, that's a bearing and a rub collar in the bottom plate.
Mine works really good. and the drive shaft has 3 flat's so it can't spin in the chuck,

I have a robo sander  but it clogs up to fast, and I had some kind of metal sanding sleeve.

Looks like great minds think alike, I put flats on too. I hadn't noticed the bearing until you mentioned it, and enlarged the picture to take a look. Thanks again for the inspiration, I'm really happy with the way it turned out. I had trouble tracking a new belt, but once it settled, I got a riser that had been waiting done.

Max, is that c-clamp on your drill press used to stop the whole issue from wanting to spin?

Yep
