Jason, I wanted .010" per inch on the wedges on that lam,so I took a couple .002s and a .001 and made .005" per inch wedges feathered to 0, the right length for the wedges. Then used 2 of them stacked to make my .010 per inch.
Then you lay them on the most perfect parallel you can make and lay your sled(the one you are making) on top and grind it to shape.
Now you make the lams.
Then to get the .001 taper overall if you want it,just lay the new double tapered end sled on your .001 sled and grind.
When done with all that,I ran just the lams thru the sander and thinned the ends down parallel,making sure not to get into the working part of the wedges. On this bow,the butt ends ended up about .075,which will bend up the belly ramps of the riser without making a thick glue line.
Hope that made some sorta sense!
It may be easier to do than explain.
