Can't report anything yet, but I was running some lams on my new sander and and was planning all parallel, but I discovered that my sled, made on another drum sander I didn't care for and couldn't seem to master, isn't actually parallel, but instead produces a taper of .005 per inch. I thought about fixing it with the new sander, but then thought again. I have one more set of lams on hand with one a .002 taper. After that I'm going to go ahead and lay up a couple of bows with two lams (I'm building light bows) and I'm kind of hoping that that total of .001 taper off of this sled will work out well... close to parallesl, but not quite. I'm finishing a quilt on a deadline, so I can't really get to any bow stuff till next week, but I'm looking forward to the result.
