ash planing problems
I am trying to plane 3ft long by 10 inch 35mm thick ash boards on a 18inch wadkin planer thicknesser. at the moment I am trying to surface plane the ash but having real problems the pieces of wood are vibrating quite a bit as I'm pushing them over the blades and the end result after 4 passes is a rocky base not level taking more off the front half it also takes a lot of force to get it over the blades. I checked my method hand flat in the middle of the piece on the infeed table and smoothly changing to the outfeed as soon as a hands length has gone over then all the weight on the outfeed. we have a suva guard over the blades. I yesterday honed both blades and double checked the out feed table with a true piece of wood and took the wood 6mm all along the blades. I cant understand why it is vibrating so much and tough to push through. first time if dealt with ash on the planner but have had not problems with beech pine spruce cedar.
any help would be much appreciated.
