Re: My 12" 4 jaw has gained weight.

I made this; rolls on home made steel wheels in channel.
I should have used bigger channel and bigger wheels, but it works ok.

It rolls forward + back, pivots side to side, and can protrude 2 1/2 feet out the door.

Re: My 12" 4 jaw has gained weight.

Never do any work by hand that you could do with a machine; and that goes double for lifting!
I wish I could say that I always take my own advice...

Re: My 12" 4 jaw has gained weight.

I put a hoist into my workshop in anticipation of upcoming weight gain of all things.
There's no use in pretending it won't happen to us.

Re: Old switch to teco L510 vfd

But when you use a drum switch as a vfd control, all that complication goes away; you only need to find on-off-on for 3 wires, with negligible voltage and current.
All those thick old motor wires can be disposed of.

Re: Polishing doorknobs

Did you varnish them afterwards?
That was the mistake I made with brass. without varnish it corrodes again pretty quick.

Re: Old switch to teco L510 vfd

Me too. I had to take the switch apart and fix it first; what a wonky old thing, I was amazed that it had still been switching the whole load of my motor. I have a different VFD, but I suspect they're similar; you can set them to be wired however suits your needs. Being able to reach for the old swi...

Re: Graziano SAG12

It sounds easy enough; transformer, rectifier, 24VDC. Unless one of those clutch coils has fused and caused the problem. Is there a fuse after the transformer? If not, you should add one. And you could check the resistance of the various clutch and solenoid coils too, look for signs like blackening ...

You're right; we might be a bit thin on engineering supplies, but we have lots of oranges.

Re: press fit lube?

https://www.kbctools.com/catsearch/909/anti-sieze We don't get any of those products here in Portugal. I used a little copper grease, went ok. There was some errors in my layout though, and the parts aren't very concentric; luckily, I know I'm not a particularly good machinist, and I made it so tha...

Re: Ball bearing manufacturing

That second vid is more for the machinist person.

I'm always amazed at bearings, how they can be so well made and so cheap.
Well, the more common sizes at least.
Mass production has killed a lot of skilled jobs, but has made some great things available at usable prices to us too.
