I recently picked up two slabs of buffalo horn off eBay, 6 1/4 x 1 1/2 x 3/8. I'm looking forward to making a couple sets of scales from them, but I hate the idea of wasting so much material sanding it down from 3/8 to 1/8 thick. My "shop" consists of a belt sander, a scroll saw and a Dremel drill press thingy. How can I split the 3/8" pieces into halves? I could do it with the scroll saw, I guess, but there's no way it would be a straight cut. What's the right tool for this job?
