Thanks for all the input guys.
The bar is 2.5@ dia and is only clamped in the middle, I'll stick it in my vise and try with a feed of 100mm/min and make sure the bottom of the tool is cutting.
The 120 PSI was way too high as suggested- it was like it was snowing in the shop lol. Chips in your underpants is scarry! lol. I'll choke this down.
I'll start again with a new tool using all the tips suggested.
Many thanks again chaps!
