I've got a 1" wide shelf of curved MDF that protrudes about 3/8" out for about 8". It's in place and after the trouble I went to getting it there I really don't want to take it out and try to run it through the TS or BS. If it were any kind of hard wood, no problem. Out with some hand planes and I'd knock it down and love the task of doing it. But MDF...I know I've heard that it's hard on handplanes. I'm at that point where I'm ready to do that. Before I do...how bad is it on handplane blades? I have no problem resharpening them. I have a Tormek and it's about time to do LOML's knives anyway. But if it really dulls them rapidly, I'd like to know that in advance and maybe I'll try to do some sanding first...Grrrrrrrr at that thought. Thanks for any input from those who've handplaned MDF...I haven't.
