Making and testing pattern
OK!
I've finished the Rotary Knight scan and carve (1/5/2012).
First I'll point out things I've learned.
1) When you bring the scan in to Pattern editor, remove the bright green border as it will cause an unwanted plunge to the bottom depth of the carve.
2) Before you bring the pattern on to the board, be sure to un check the Scaling box at the bottom of the library list.
3) I left the depth alone.
4) I made my design board slightly less than my pattern width. In my case the pattern was 7.14 and I set the board to 6.898 (I used 6.9, but it went the the lower number).
5) I feel that the use of the Optimal carve is a must for the rotary carve. It takes more time but avoids taking too big of a bite out of the stock, which could make it rotate out of place (OOPs, that is why my first test happened).
6) If you feel that your dowel has too much play, on the Y-axis, use a flat washer the remove that play. We want it free to roll, but not loose enough to move left & right.
7) Since I have not made Ed's vacuum box, and I do have a top mounted vacuum head, I redirected the muffler in to the rear of the jig. I pointed the flow at the non-keyboard side. That kept me from having a sawdust build-up at the worst spot. I never stopped the unit, but I did use another air source every once in a while to blow the area.
I've, also, talked with Ed about limiting the depth of his pre-drilled holes to 1 inch. For the type of carve lay-out, I do not want a hole in the end of my carved item.
