hi guys, need a bit of help , does anyone know where I can source a replacement for this drive wheel? it's off a gem stone tumbler but something must have gotten stuck last night and tore off the cogs either that or it got brittle due to old age
dimensions are 45mm by 10mm , hole diameter is 4 or 5mm
made from plastic or nylon looks to have originally had 54 teeth
thanks

Do you know anyone with a 3d printer ? That would be my first place to ask.

Gear Wheel

Search ebay for "54 tooth gear wheel", there's a few examples, not identical but you may be able to adapt to fit.

If you have the make of the tumbler, you will possibly be able to source spare parts for xxxx Tumbler as there are loads of spare part company's for these items. Good luck!

If you don't have any luck with spare parts there's a company called HPC Gears who specialise in all kinds of gear wheels. They have an online catalogue which you will need to trawl through. You will need some dimensions such as diameter, number of teeth, width, bore size etc. I have ordered various standard gear wheels from them over the years. Good luck with your search.

Just had a quick look on HPC site, going off your dimensions it looks like a 0.8 module spur gear which at 54 teeth is 44.8mm outside diameter. They don't list a gear with your exact dimensions so you may struggle unless you have one made to order.

Hmm, who'd've thought a 3d printer would be made of cast steel and weigh 1500 kilos. What sort of logic system is it using?:)

It would have taken ages to draw & slice a graphic for this, then 3-4 hrs to print. This was done in 20 minutes using good old micrometers, slide rule & the back of a fag packet, one cup of tea, & 1 fag. Sometimes, new fangled isn't always the best when it comes to one-off jobs. The logic system is built-in to in the operator, its called "experience".
