Then my calculations seemed to work much better. The rest of the code runs in G90 mode. So late this afternoon I went out & bought a 6' 1x12 that I can nibble 4" at a time from & use that as throwaway test pieces. Poor lumber though, flat sawn and the trees original central twig runs right thru the length of the board about2.5" from one edge, so the first thing I have to do is give it a drink of superglue & slap it in a 2 foot Bessey style F clamp for half an hour else it falls apart just trying to put it in the jig & get it clamped down. I have a couple of them laying here, but the fit is too tight, so I need to add or sub, about 3 thou depending on which corner its carving in order to loosen the fit enough to actually drive it together. But I am not yet done with the code that cuts the mirror in the end pieces so a true test fitting is not yet possible. And my back is yelling so its done for the day. So I'll sit here and play with the code to widen the gaps about 5 thou for an easier to drive together fit. What I'll likely wind up doing is setting up a #<_fudge> variable set for a couple thou, subtract it from the length of the top run, and add it to the length of the bottom run. So a two thou change will actually make a 4 thou difference in the fit. Whether tat will be sufficient when converted to Mahogany, I have no clue until I try it. Final fitting of course will wait till the Mahogany gets here and I find out exactly how wide two 1x6 boards, edge glued together, actually are. They said they were s4s, 3/4"x 5.5" wide, which would be 11" total. But I swear these guys use a rubber tape measure at times. It's supposed to be 11.5" wide, but I wasn't able to find any '1"x12"' in anybody's web page. So this chest is going to be 1/2" shorter vertically than the magazine version. I doubt it will be noticeable in the finished chest though. Thanks for the hand holding John, you did make me look at it a hair differently. I also printed out about 6 pages from the Usermanual.pdf, which had the coverage of G2 G3 in it, and which is not available in the wiki that I was able to find. Wasn't there a search engine in the wiki at one time? That printout answered _most_ of my remaining problems. Thanks John.
