Re: DIY Hyd Pump
What kind of demand do you think there would be for these. I can probably get it all done, would have to do some prototyping and testing first though.

Re: cnc ?
Steve, if you can find it, may be difficult. Try and find a manual mill that uses the same toolholders as your CNC, saves a TON on tooling costs.

Re: cnc ?
Not postive on the Cat 40 in a NMTB 40 spindle, might work, if the drive keys are same etc. I'll check the handbook and double check they are the same tapers etc.

Re: What mill to buy
