I saw a Bow Saw maker's wares on EBay. He had some very nice items. I sent him a msg asking if he had an 18'' saw with a rip blade. This would be used for resawing. He said he could supply one but the did not recommend resawing anything wider that 6'' with their saws. I can saw that on my band saw.
Then I had a great idea. I have my fater's Disiten(sp) rip saw, the one with the hole in the tote for other hands thumb. It had been sharpened a long time ago. I took into a 1ft length of cherry that was about 8'' wide. Yes I worked up a sweat but I think with a good going over and a sharpening it would to much better.
