Hello. I'm trying to restore a Gerber D200 CNC router on a hobby (cheap) level, since I'm from Eastern side of Europe shipping here from US costs an arm and a leg, so I was looking for cheaper solutions. This router was laying in my garage for the last 7-10 years and I have no idea how my Father got it. Router is missing all electronics, but this is the thing I can handle, the biggest problem right now is the spindle motor. Being in this side Europe everything we have here is in metric, while CNC router was made in US. I think it still has original spindle motor Porter Cable 86902, sadly routers 3.5 inch are unavailable here. Original collet is shattered, replacement with shipping costs 50-70 USD and only comes in imperial size for bit shanks. Original nut should not fit ER type collets (did not test yet) and it has proprietary nut tread M25X1.25 or something like that, so I can't get an ER collet nut. Changing whole collet chuck is also hard, as there are no chuks with 0.5-20 UNF thread other than drill ones.
So my question is, what should I do?
Go for new 3.5" spindle motor and spend a fortune on shipping? If so, what would you recommend with ER collets?
Buy a drill chuck and hope for the best? This way it's really cheap.
Throw away 3.5" mount and try to fit 80mm design?
Thanks in advance.
