- This was supposed to be a quick video to see the installation of a motorised spindle on the Mini Lathe. As will become apparent, things didn't progress quite as smoothly as I hoped. It ended up taking more than three weeks to make, involving as it did several emails and waiting for replacement parts from China. Still - it all worked out in the end - or did it? Watch to the end to find out.
(I bet some of you jump to the end! I know I would.)
Great stuff ! It's a chunky beast, hope it works fine for you.
Nice to hear that the seller and manufacturers were contactable and willing to help when the first one was faulty.
Looking forward to seeing the anti-backlash nut being made.
Thanks, Colin. The anti-backlash nut is going to be fiddly due to its size. I'm not used to working on bits of material that small. I'm thinking of 3D printing the major parts and turning the actual nut bits as a glued-in sleeve. John.
I'm planning to do the exact same thing on my lathe. I've recently come across a 2.2kw 18000 rpm spindle from an old CNC and I want to try to use it as a grinding spindle on my lathe.
Good luck with that! That's nearly 3 H.P! I just hope that your lathe is a good deal bigger than mine. John.
@@bizzibeeworkshop it's a bit bigger but for a 3hp spindle is still a bit small. I at least want to try
That motor doesn't sound right sounds like driver is incorrectly set.
Your hearing is obviously far more acute than mine. I wouldn't know what it was supposed to sound like, even if one of my hearing aids wasn't broken!
How about a warning so the rest of us don't accidentally buy this crap. If they're happy to ship you something that doesn't work without having tested it first then I would prefer to avoid them. Getting a replacment for "free" isn't really free if you've had to spend time on it. I don't mind spending my money on a product but I become incensed if I have to spend time as well. At that point the price becomes too high. So what is the brand and who is the supplier please. Adiitionally, indexing with a lathe seems a bit silly. Use a mill with a DRO and work out the X-Y point co-ordinates and drill away!
@@waynepetrevan The warning, if any, is needed is implicit in the video. You are free to spend your money how you wish. I've chosen to spend my money on this motor, and the fact that it failed after a short while is just unlucky in my view. As to using a mill with dro for indexing - I heartily agree and that's how I'd do it if I had still had my mill - but I haven't.
