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.
