Wood is .62" thick Butternut. Trying for a scrollsaw look with a 1/2" piece on bottom to be glued in a pocket of a black wood(C-90 Torrefied ash) for business cards. The intact one was cut in a pocket toolpath with a whiteside 1/4" shank 1/8" downspiral with no clearance tool(50 minutes). lesson 1: PREVIEW it pocketed the interiors of the letters LAST.
So next one pocketed letter interiors separate toolpath first, then cleared with the 1F .25 upspiral that came with the Desktop starter set(still trying to find something it's good at). TEAROUT bad. I left a .01 pocket allowance which the same whiteside ALMOST cleaned up. Tried to change pocket allowance to a negative and vectors in preview went NUTS. So tried a second pass hoping no bit deflection(climb cut)would clean it up and it looks like the bit grabbed it on the first pass and chewed it loose.
QUESTION: The board took on a slight bow so the center of the board cut clean and towards the edge had a very thin skin---should I have left a skin on, on purpose, and sanded it off afterwards?
First attempt at this style, but I like it. Should not have used that upspiral though, downspiral next time.
Comments very welcome on anything I did wrong.
