As I mentioned in Bob's "Rest Machining" thread I had planned on doing that same file. Now, I don't have a clue what Rest Machining is
so I proceeded with what little I knew. He was gracious enough to PM me with his dimensions and some info on the two finish files he setup to carve his. I have considered for some time to run a project with 2 finish files but until now hadn't done so. Bob shared with me that he hadn't used a rough file .... me, not being smart enough or gutsy enough
, ran a rough and 2 finish.
Started with a piece of cherry 18" x 5.5" x .85".
-Rough: 1/4"em, 41% step over, FR@110 ipm, PR@50 ipm and .125" pass depth. Took 50 min.. This I think, proved to be a little much. Got a bit of undesirable chip out that I'll need to fix with a dremel
-1st Finish: 1/4" bn, 10% step over, FR@130 ipm, PR@40 ipm. Took 28 min.
-2nd Finish: 1/16" bn, 4% step over, FR@120 ipm, PR@40 ipm. Took 5 hrs 21 min.
When I originally set it up a few days ago with just a rough and a finish (not the same settings) it gave me an estimate of just under 11 hours.
Anyways, here's the result with out any sanding or finish.
Always trying, always learning
