Harrison Mill Conversion

**m_c** · 21-01-2009

Not much.

Got a 50V toroid and tested it a while back, which gave a nice 75Vdc when I tested it.
Bought a metal cabinet to house all the electrics, but it's still sitting in it's packaging.

Been too cold outside to do much, plus what time has been spent outside has been on a couple other ongoing projects.
Hopefully get back to this next month.

I presume this conversion died?

I know this is an ancient thread to drag back from the dead but I'm converting a Harrison Milling machine myself and just wondered if it got any further than the last update or if that was it?

Take a look here if you haven't already - a very tidy Harrison conversion. Pics and videos of finished job on the last page of that thread.

Well and truly dead!
.
I realised just how much of a pain doing a good manual to CNC conversion really is, sold this machine, and bought a bigger barebones already CNC'd knee mill, although progress on that has been very slow, as other projects keep getting in the way, and I keep dithering over the tool changer.

Haha, I've known Andy for many years and it's his fault I'm doing a Harrison in the first place (that and I already have a Harrison Lathe). :) Mine is not going to be as neat as his though. Mostly because he used driven nuts for Z and X and I'm just going to hang the motors in the breeze and spin the ballscrews.

Figured as much but nice to have closure. :)
