So I was talking to a buddy of mine, and we started discussing how to get a board truely sqaure... and so the differences between Planers and Jointers was the topic... and I'm sure there's varying "true-ness-es" - let's just say, generally true, good enough for nice woodworking projects...
He said that the only way was with a jointer. Well - we have a 6" that I'm "housing" for him until he sets up his garage... and so you could only face and edge a 6" board...
I argued that you could do it just fine with a planer... for the flat part and then a jointer for the edges...
He said if you plane a "cock-eyed" board, what you will get out is a slightly thinner "cock-eyed" board.
I have a ShopSmith planer... so thats all the experience I have on those... But I sent a couple boards that were quite a mess - and they came out purty darn flat.
So he says for me to get "on that forum" and ask those guys...
Well - Anyone care to join the argu... uhhhm... errr... Discussion!??!
