Regarding Walt's suggestion, here's a way we O.F.'s do it on Cubs and other rag bags:When laying out your rib spacing per A. C. 43-13, or whatever reference you use, remember this trick: Lay your elastic on the underside of the wing (shortest distance from l.e. to t.e.) and make sure it isn't stretched. Starting from the rear edge of any leading edge covering, mark your spacing, being sure to mark the back of the trailing edge, as this will become a reference mark. Don't forget to mark both the tape and the wing. Move your tape to the upper surface, stretch it to fit the upper camber and tape it down. The forward mark should be the same distance back from the leading edge as it was on the bottom camber. Mark your wing surface at the expanded reference points. Do this on the outermost rib and on the innermost wide stitch rib, run your chalk mark, and do some sewing. By stretching the tape like this, you automatically adjust the stitch spacing, and will have less problems figuring out where to punch the needle holes to have the stitches line up. It's actually easier to do than to read about, and negates a common problem area. Try it, you'll like it!EdDannymac, I had done my Fisher 3" outside and 2" inside propwash area. Think thebook calls for " the prop wash distance, and to the next full rib".I used a trick I saw somewhere, that worked great...get a piece of "white elastic garter" the kind you would get at the sewingstore. about 3/8 or 1/2" wide by about 6ft. lg and put marks every 1 3/4" orso. Then on innermost rib to get wide spacing, and tip rib, mark wherefront and rear stitch will be ,and lay end mark of garter on front andstretch garter to rear mark. now stretch garter till you get the spacing youwant. you always get even spacing. Mark this rib and tip rib. Then doprop wash area with closer spacing. Snap chalk lines, and you're ready tostitchWalt Evans-----Original Message-----
