    There isn't a nipple on the screw itself. The bits that move are the bearings and the ballnut - the rest just needs a slight surface coating to protect the metal. The bearings are sealed, so its just...

    Cutting aluminium on a table saw is no big deal. I have a Bosch GTS 10 J and with the Bosch blade made for cutting aluminium, it cuts aluminium like butter. Squaring the saw took some effort, but now...

    FY! a charge pump is an electronic circuit that's usually used to generate a low-ish power but higher DC voltage from the existing DC supply using capacitors, rather than an...
  7. Re: School me on the best machine for big hardwood

    At least the brushes appear to be easily externally accessible - so easy to change I would guess.

    Do those motors have integral brakes? If not, you might need to add one on the Z axis if you're...
  8. Re: School me on the best machine for big hardwood

    Aye, they're the things - a lot cheaper on Aliexpress though! When I get my machine finished I'll bum a bit of hardwood off Mike and see how smoothly they cut it.Theoretically I can't see that there...

    Re: School me on the best machine for big hardwood

    Hi bluesking

    I can see why you want to go for larger cutters and for roughing I would agree, however there is another factor to maybe consider dependant on the guitar design/type you are looking...
  12. Re: School me on the best machine for big hardwood

    Your requirements are not a million miles away from what I want to end up with, except mine will be used for building high-end loudspeakers rather than guitars (hence needs to be a bit larger); I've...

    Re: School me on the best machine for big hardwood

    Yes bigger more powerful spindles like 3 kw you can use bigger cutters. If you want more motor power then use nema 34 but then you need higher voltage drives (mains voltage type).
