I've been working with some oak that has been giving me fits with tearout from my planer and jointer. The problem is with grain reversal. I run it through one direction I get tearout, reverse the feed direction and the tearout occurs at a different location. The jointer knives are brand new and the planer knives have only seen 5 small projects. I've tried all the usual tricks, skewing the piece, wetting the surface, taking really light passes (1/128") and nothing works. So after my experimentation I thought I would ask some of you more experienced woodworkers. A drum sander is not in the budget right now so I need other options. I can spend hours with 60 grit paper on my palm sander but that ends up dishing the piece. I've tried hand planing with a #4 but it has the same issues with grain reversal. My card scraper does the job very slowly, but my thumbs give out before I can remove the tearout. How does everyone else without a drum sander deal with tearout?
I think I remember David Marks mentioning on his show, to back bevel the planer and jointer knives. Has anyone else tried this? Does it help with tearout? Is it time for me to get a Veritas cabinet scraper or scraper plane? Would that be more efficient and less work than a card scraper? I suppose a random orbit sander would also remove material faster than my palm sander, but I just hate the dust sanding creates.
Thanks,
