Hi,

I'm sure (not exactly sure but would expect) that there will be connections for a braking resistor on your VFD.

My lathe is a similar size to yours and I can stop a 160mm chuck from 2,400 rpm in less than a second.

I have 2 off 220 Ohm 50W chassis mount resistors wired in parallel and fastened to a smallish finned heatsink. (Equivalent to 110 Ohm at 100W I hope.)

Cheers.

Phil.

P.S. Loving your videos.

Thanks Phil, the Lenze brak module for this VFD is 300W, but since there is a mechanical brake mounted on the motor shaft already, I would rather just let the vfd coast down, and mechanically brake the load. Havent worked out whole to set that yet.

I took a Uni course in machine tool design, and figured I'd try out what I learned on the Schaublin...

I didnt post last weeks video to this thread, as it was more of an unsuccessful casting vid than a Schaublin progress report. This week is better.

This week it is the X-Axis motor mount...

I have never had a power chuck before...

Bit of lathe work on the Boley required this week, but good progress...

It is looking more and more like a lathe...

A step backwards this week.

I was wondering when we'd see some more episodes - thanks.

Hi Phil,
Sorry about that. I was back in NZ for a month, and also working on a few other projects.

Don't apologise!

I thought setting up Mach3 with stepper motors was complicated enough. You've put me off servos.

Cheers.

Phil.

I am sorry to hear that. I think I am pretty lame at this stuff, and most people could do it much faster and more easily than I do it.

Adding conversational programming is a real game changer for a home shop machine like this...

Bugger!

Better luck with the next one.

You may have got away with it if you didn't keep taking a cut on the taper. A short parallel section wouldn't have done any harm.

When using the 4-jaw I find it easier to use 2 keys at once.

Thanks Phil. Good point.
It will be easier once I have the control panel set up and can more easily switch it out of back gear, but yeah, a second key would be quicker.
Cheers,
Mark.
