Hi Mark, us Brits are a rare breed on these sites, it's good to know I'm not the only one!
The resorcinol I'm using is called Cascophen Polyproof I think, made by the same people that did Cascomite which English bowyers apparently swore by for decades.
I'm guessing it's the coarse blade that's making the rough cut, although it may be wobble caused by the coarse blade (due to the wide tooth set). I found a book in my dad's bookcase called 'The Bandsaw Book' and it states that the blade the author uses for resawing with a smooth cut is a "carbide-tipped, 2/3 pitch, variable tooth" blade. I went to the only place I know of that might sell those blades but their suppliers don't make them.
If anyone knows of anywhere that sells them it would be so helpful but at the moment I'm looking into the 'Wood Slicer' blade at Highland Woodworking. If anyone's used it, is it as smooth as they say?
I've read that if you rip hardwood veneers with the wood slicer you hardly need to sand it at all, and that's if you're wanting a touch-smooth surface.
Thanks
