The last time I broke a tap was about as ironic as is it possible to imagine. I broke it using LinuxCNC and rigid-tapping, having forgotten about a bug that existed if you stopped the system mid-cycle on a previous rigid tap. A bug that I myself had fixed months ago. And a fix that was in the latest release version, that I had released a week before. But that I hadn't updated to. I tried to dissolve it out with Alum, and it looked like it would have worked had it not been a blind hole (it was in brass, the technique doesn't work in steel such as your motor shaft). But in the end I drilled through from the other side. This wouldn't normally work, but in this case the tap had been plunged straight in at rapid speed, so wasn't really engaged.

Tapping with a drill and using small taps is almost always a bad idea. If you must do it, use a spring drive for 1/4" or 3/8" sockets and a mini chuck. Personally, I've always taught people to use hand taps for 5~6 holes, you can feel whats going on and snap way less taps. You also have in effect a 8" extension to tap length which makes it very easy to tweak sideways snapping tap off.

If you havent started, consider trading it in for something with more iron in it. Even the 9x20 chinese lathes beds are much more rigid, or an old Emco/Myford etc. The missing support for the headstock rear end is not likely to be the main driver. The open profile, poorly ribbed design would have a rather low moment of inertia. If you cast the whole bed into a epoxy granite block, you then have the problems with chip evacuation.

The Indramat servo drive can actually run directly off 240V single phase with no real modifications. 24VDC now comes off a DIN power supply, which is a lot tidier than the 3-phase stepdown transformer, diode bridge, and capacitor setup that the machine came with!

True, there comes a point in a project as poorly planned as this where you just want to finish, and (often bad) compromises get made.

All that scraping and turd polishing and you butcher the bloody pulley !

Yep, that was lame.

Hi. I really enjoy your videos, but I am afraid I will have to unsubscribe. KZread has flooded your videos with advertisements every 3-4 minutes. It is very annoying :(

The whole ad thing on Youtbe is getting out of hand. I'm considering paying the $10/ month subscription to never get ads.
