Woodmaster chatter marks
I see by the postings you are still having problems with your WoodMaster. I have a question/statement to make.
Do you have full length infeed and outfeed tables for your Woodmaster? I'm not talking the small ones that come with the machine, but 8 or 10 foot long ones? Each of my tables are 8 foot long and they are still too short in my opinion for when I plane 10 to 16 foot stock.
I'm pointing this out because any 'bounce' or vibration at all of an unsupported board will transfer the vibration to the planer head and make a chatter mark. BTW, rollers will not do the trick because the board will still bounce where it isn't supported.
Just some thoughts!
It's a biiiig mistake to allow any mechanical object to realize that you are in a hurry.
