Giday, Shane. I was looking for the most info I could get while contemplating the rib jig and finally ordered the one piece drawing from Leonard. When I first received the plans, I was not aware that a one piece drawing was available and went ahead and ordered the supplementary plans from Scott in Iowa and proceeded using those for my jig. I couldn't seem to make Leonard's paste together rib drawings match up with the one piece copy that Scott sent and became curious, only to find out later that Scott's drawings show " another way to do it" for lack of a better description and his dimensions may or may not match those of Leonard. So we have "options". Several replied and said there's nothing to worry about, " it'll work just fine anyway" , " it's just not that critical" etc. I just took another look at Leonard's one piece rib drawing and if it would be helpful, tonight I could take some accurate measurements and post them here for you. That would allow you to draw a straight base line and plant those piece by piece drawings right where they should be and have something to work from for your own full size drawing. Leonard's $13 drawing is one piece and it does match up nicely with his page by page drawings which tells me they didn't get skewed or altered by the copying process.
