Hey Guys, assuming this is okay – looking for someone with experience to tell me yes, or no. My planer leaves a much nice finish than my jointer as this time. What I’m wanted to do is this – flatten face, joint, clean other on TS and then plane to thickness just above my desired thickness. Now what I want to do is flip board over and take last 1/16-1/32 off the face jointed side. Any reason/s why I shouldn’t do that?

Nope. As long as your reference face is flat, you are fine. I do it all the time, sometimes flipping the stock multiple times for the last few passes to final thickness.

Thats is pretty much the sequence you use on rough stock !
Just curious why jointer is not leaving as smooth a job as planer ?
Perhaps knives need sharpening.
Both machines should leave same result

Agree with Brad. If you’re removing a significant amount of stock, it’s a good idea to try to balance the amount on each side of the board so you don’t risk having one side with more moisture than the other, which could increase the tendency to cup or twist.

Thanks, guys – that was my thought. As long as my reference face was flattened and I took enough off the top with planer to reach the same plane, I should be fine.

In regards to Rich, I’m not really taking much off here – stock is 4/4 but shy of that by a little. I’m taking down to 3/4 heavy. Lastly, I think my knives do need sharpened/replaced – need to look into that soon.

Thanks again for the confirmation! Rather ask then to have a bunch of lumber that isn’t prepared correctly.

Have your say...
