It could be the pump is designed to only run for a set period, after a set pressure has been reached, then switch off. If it's a continual pressure pump, then I suspect it's not meant to run continuously on such a small machine.

I'd guess just a pretty standard insert parting tool would work (small tip type, not big flat blade type), with the holder cut shorter if needed.

Thanks. The problem is to tighten into the slot you need to get behind the tool. Ive done some CAD drawings of the setup. Just rendering them quick, not sure if it will show the issue.

I made a bracket but out of alu which bent. Might try one from steel instead. The issue is the Glanze tool I have has a max of 25mm, so not ideal. The blade type would be better.

Ive drawn the blade holder in glass to see through it. It can be shortened, as it will hit the rear of the turret (centre).

The issue is how to tighten the 'spacers' that are use to squeeze the 12mm tight against the turret (vertically)?

The question is how to get to the nuts to tighten up.

I could drill the holes at 30 degree and use the drill bit holder 'holes'. A bit risky and need a sine vice for that. Alternately perhaps cut slots to allow me to get to the size 8 spanner to tighten up.

What diameter would you like to part?

Well, more than 25 if possible. There will be a limit, need to measure the max. With blades this can be adjusted.

GTN style insert up to 32mm diameter - https://www.shop-apt.co.uk/part-off-...2mm-shank.html

WDN style insert up to 26mm diameter - https://www.shop-apt.co.uk/external-...max-depth.html
(APT do do a 32mm version, but they're showing as out of stock)

I personally use the WDN style, as I couldn't find a reasonably priced 12x12 shank holder for GTN types when I was originally buying holders.

Thanks. This one will be better. What I do need to find out from APT is the size of the 'head'. If its too long, then even cutting some of the rear off doesnt help as the head will protrude. This is the issue I have with the Glanze unit that I have.

If I remember, I'll get some rough measurements for you when I'm in the workshop later, as I've got a couple different ones.

Thanks. Appreciated. Ive emailed APT support, ive used them in the past and they are really good but finding a parting solution for this otherwise excellent little CNC lathe.
