It sounds like an interesting project but my advice is to save it as a third of a horsepower motor and look on Craigs List for a spindle sander. Mine cost $75 and does things adequately.

Hello there i recently salvaged a broken robot coupe for those who dont know what this is ..... its a heavy duty food processer thats got a 250w motor in it and around 2 inches long of a 1/2" stainless hex shaft I plan to turn it into a spindle sander (ive heard that at this rpm it burns the paper but this doesn't matter because its only for the very final sanding on forms ) Ive bought a sanding drum for chucking up to a drill press thinking their was some kind of ingenious sandpaper locking device , their wasn't Also ,from the pictures I thought from the picture it had a coupling to fit the hex shaft on my motor .... it was round Anyway I managed to bodge a sleeve of cut pipe tight over the hex shaft and onto the drums coupling turned it on only to find out its totally wobbley...... Basically i need a longer shaft for an axle at the top of the drum for stability Ive looked EVERYWHERE for a 3" deep socket ,extension or coupling so i could mount it on the shaft and fit a sleeve over that to make a shaft extension The only other options i can see is to get some specialist to weld another extension on or turn this project into a big one by attaching a pulley to the shaft and gettin more parts exc Could i just remove the original shaft? any suggestions folks ? thanks in advance tomas |

This small Oscillating Spindle sander from Grizzly has a 1/2" arbor. The rubber sanding drums may fit your application. An email to Grizzly customer service would confirm it. http://www.grizzly.com/products/g0538/parts I would hope the replacement sanding sleeves are available in Ireland. After Googling those food processors I would try to trade it for a nice sander. They're the Rolls Royce of Food Processors! |

Thanks for the replys guys after looking everywhere for a "hexigonal tubing" coupling it seems like its cheaper to get/buy/find other parts than get it from the usa It seems im gonna go the full hog and make up a seperate shaft thats belt driven from my motors shaft attached to a frame by 2 pillow blocks the same as on a drum sander with the pulley in between them The only thing ive got to find out is what kind of bearing to get to mount the vertical shafts weight on . So far .the diameter of the new shaft is depending on this bearing ive got a broken bits of a garden mucher /shredder and i presume that it has a vertical shaft bearing ill report back when i get a better idea on the new parts im trying to source any suggestions appreicated though espically on the pulley sizes as ive never done this stuff before Thanks again tomas |
