Drive suggestions for DIY RCM?

I picked up a Black & Decker Jar Lid remover for $6 at a local GW. Has a nice geared-drive motor in it that spins a platter at about 5 rpm and is designed for high loads. It has a square output drive on a shaft slightly smaller than a spindle. I adapted a RC plane foam wheel to contact the platter. Only downside is that it has a spring switch that'll need to be replaced. Haven't constructed my RCM yet but it's another alternative.

Well, here is sort of an update. After trying to rig an automotive winshield wiper motor to a 12 volt power supply, I am going a different way. I found a small countertop Krups ice cream maker at the thrift store cheap. It was missing the bucket. I have harvested the geared drive and switch out of it and have rigged it temporarily to turn on. It has lots of torque but riggiing the gear(s) to a turntable spindle is presenting some challanges due to the geometry of the gears and mounting points. what I need to find is an intermediate plastic gear about 2 to 2-1/2" wide. Anybody got a cheap source for plastic gears?
Once I get this thing working, I plan to post again with photos. Also, I picked up 2 turntables at the flea market for $5.00 each, as possible spindle and parts donors. The seller said they were broken. The JVC-JLA20 appears to only need cleaning, lubing, headshell wires and a new belt (plus a cart) so I think I will rescue it. The dust cover is covered in scratches but otherwise intact and undamaged. So the Fisher MT-30 will be the one that gets cannabalized. While I was at the flea market, I just could not pass up a $15.00 box of 65 records. All rock pop and jazz from the 70s and 80s, most in good shape, Including YES-Fragile and Moody Blues Days of future passed in really good shape.

Ok folks, here is an update with some pics. My DIY RCM is not yet together, but today I found some 3" foam rubber RC Airplane wheels that I think will work. Tomorrow, I hope to have a mockup of the mechanism assembled. Here are some pics of some component pieces, including the homemade vacuum wands I made based on another posted design on the web.
The picture above is a crude non working mockup of the motor to platter arrangement for the record cleaning spinning machine I am building. The vacuum part is a separate hand held system. Parts Cost so far, flea market turn table-$5.00; Krups small table top Ice Cream maker-$10.00; Pair of 3" foam rubber RC airplane tires-$9.00, Misc screws and mounting hardware- $7.00; box to mount it all in plus a switch- cost not yet determined.
This photo shows the wash (black) and rinse (white) vacuum wands I made from narrow vacuum nozzles. I found this tip on the big DIY RCM link I Googled and copied it, but I tweaked the end caps. I cut up a white light switch cover plate to make two end cap pieces and epoxied them on. The pads are replacement Mo Fi cleaning brush pads, cut in two. These wands will work with a old cannister vac I got from the Goodwill store but Home Depot is running a hand held shop vac type for $20.00 that I may buy. The manual platter in the back ground is from a cheap Sanyo all in one stereo with turntable. Its not real solid. More about the record weight in a moment.
On a separate but related note, the two pics above show a hand held record label cover/clamp I made based on the design posted in a related thread here on AudioKharma. This is for covering the label and hand holding the album to preclean really nasty thrift store and flea market finds before doing a normal cleaning routine. Cost was $6.00 for the male and female clamping knobs from a local tool and woodworker supply house; $5.00 for the 2 each 4" round gray plastic electrical box covers from Lowes (or Home Depot), and $1.25 for the 1/4" C clip to hold the cover to the male clamp.
This is a home made record weight/label cover I will use on my RCM. Parts are another 4" gray plastic electrical junction box cover, a Driveline Gear Spline from Tractor Supply for $9.00 plus a plastic push in cap for about a $1.00, and some glue and black spray paint.

Geez, at this point, I think I am presenting to an empty auditorium. maybe I need to move or repeat this in in the DIY section. ANYWAY, here is a progress update:
IT LIVES! My prototype is now a working prototype:
The motor is now coupled to the platter rim by a 3" diameter foam rubber Remote Control Airplane wheel by a company called Hanger Nine. I screwed it to the top of the "knob" on the upper gear that originally mated with the ice cream bucket. This mockup works really good. On the left you can see a piece of 2" PVC pipe and a glue in mini drain. I will use 4 like this to make legs for the RCM. But, first I will trim, edge, stain, and seal the plywood. Then reassemble the mechanisim and add the legs. Plus I'll probably change out the switch, and then get serious about cleaning and vacuuming my records. I hope this inspires some one else in their DIY record cleaning machine quest.
PS: I found and substituted a 2 speed motor from a GE table top ice cream maker for the single speed Krups model I first found. If anybody gives a rip, I will try to post again with the finished product. Helloooo?

Just jealous! I have the parts but haven't found the time to get one together. Go man, go!

Thanks guys, I have now taken the RCM apart and am finishing the wood plinth and making legs for it. I have also bought a better DT rocker switch for it. I am installing a removable small post on the plinth for the hand held wands to ride against while cleaning.
More pics when it is finished
