I’ve seen several posts before stating that a planer will not flatten a board. I have a 735 that I’ve been using for several years and have run several hundred bf and never had any issues with flattening a board. What am I missing? I don’t even use my jointer to “edge” I use an Incra LS.

When we talk about flattening a board, we are talking about getting the twist or bow out. A planer will not take the twist or bow out where as the jointer will.

The planer makes the two flat surfaces parallel. If the board is not flat, say it is bowed, the resultant planed board will have two nice parallel faces, but it will be bowed.

Roger,thanks for the tip but I gave up my sub to Wood. Got really tired of getting a notice every month when I was paid up for a year. I buy their mag off the stand if it has something I want to read.

You don’t have to subscribe to Wood to get on their e-mail list, as I recall it’s a free service they offer.

The planer roller will compress the board since it’s intention is to make both sides parallel whereas a jointer will remove the high parts and make the board flat. It’s possible to remove cup by taking light passes with a planer but it’s not really the right tool for the job. A planer will not remove bow or make two adjacent sides square.

Is that why they call them a ”Thickness Planer”? LOL
