Neville...
Glad to see you are back at it, Man. I thought I might have to repo the old girl and knock the cobwebs and rust off of her! Nice work.

Not to worry Gary, she is a beauty, I like her before but I'm so impressed with the rigidity and mass of the machine. I look forward to cutting aluminum now, not how it used to be . I'm in love again ��

I think my friend with the fadal would be envious of the edge finish there. Is there a trick or is it Gary's machine?

[dubliner]

Id like to say it was me, but it was Garys extremely well built Shopbot, well that and the right bit, feed and speed. 30 thou. passes, 15k rpm, 1&1 IPS, coolant mister and this bit: or similar. The grooves behind the cutting edge seem to polish the cut. Use as small a cut length as possible and a ramped entry. Ive gone up to 2 IPS on long straight cuts, but 1IPS seems to be a sweet spot for small and distance cuts on the same part. Bits of this type from any manufacturer seem to perform very well, and I have had rather successful performance out of the equivalent Onsrud High Speed Steel version on this machine Im happy to say. I did not acheive the same quality with HSS on my 120" machine. Im comparing apples to banannas though. I should also add that solid, unmoveable hold down is imperative. You can see slight chatter when I didnt have solid hold down.
