OK .Test bore was fine at 450 rpm. But I have another problem.Mini Mill has very shallow vertical travel of 10mm.What an anti-climax!!!! That's life. May try coming up with some "bush engineering" to get more vertical travel.
BoreHead will be "On Display" at my Nbook desk. See foto.

May consider buying another Sakai Mill with larger vertical travel. Been eyeing attached for long long time.Will have to work for it.Basis my investments make good money.No fancy Inverter Speed Control,just plain good old fashion belt shift to change speed. So no worrried about electronic board burnouts.

My DIY Boring Head came out retirement to bore the segment on Webbie's fuel tank support. There was no way to clamp on four jaw chuck. Neither do I have a facing plate. BH turned out to be quite versatile. Used the lowest spindle speed.
