Anyone see any reason why cutting the taper before building the spar would have any advantage? Yeah, I the spar is 8.190" of an in thick at the root. Good luck finding a saw that will cut that deep. I used a 3000 dollar delta chimerical table saw and it could only cut 3" in depth. If I had it to do over again I would do it the same way and that is build a sled to push though the saw. If you build it right your spars will clamp down to it and all four caps will be within a few thousand of an inch. After you cut the taper on the fwd side of the caps you will have to start thinking upper right and lower left, upper left and lower right for the next two sleds. You will need to build 3 in all and this can all be done in one day. I saved all of the tooling I have made just in case I finish this one and want to build another. The only difference I would make is buying spar stock that is thicker than what the plans call for. I would then plane it down on a joiner to make it strait, true and square. For the center spar caps I would add at least a half of an inch to the vertical thickness and for the outer caps I would do the same at the root to allow plenty of room for placement of the wing attach fittings. Also make sure you use the correct blade in you table saw for ripping and cross cutting, you might want to ask you local wood working supply shop for the correct blade that will give a good glue joint when cross cutting or ripping but be prepared to spend 150 dollars for each blade. I would bet I have a 1000 tied up in just in saw blades alone. If any one would like to see pics of my sleds I will be happy to dig them out of the attic and snap a few digital pics.
