So after upgrading to a bigger jointer and able to joint long boards now, I’m wondering about my lunch box planer, porter cable to be exact. Are there length limits with small planers like them to be able to flatten long boards consistently through the whole board? Should I build a longer in feed and out feed tables and get rid of the small metal ones attached to it. I’d like to upgrade to bigger one eventually but wont be for awhile.

I recently ran some 12 ft long red oak through my Ryobi AP-12 without any major issues. I had two roller stands one in the infeed and one on the outfeed.

The length doesn’t matter as long as it’s supported.

I agree, I have a small planer and if you support both the in feed and out feed you will be fine.

Not meaning to insult anybody, but there may be Nb’s reading the post.

So just to clarify planers do not flatten boards, they thickness them.
Put a warped board in you’ll get a warped board of uniform thickness out the other side ;-)
(Actually not 100% true, you can get a degree of flattening with very wide timbers.

You’re going to find these planers are not built for heavy, continuous use, so be careful running long, wide boards only take 1/32’ per pass, especially on hard woods. As you’ve probably figured out, you can tell by the sound you’re overloading the machine.

Make or git you a couple roller stands to keep everything cool.

When I needed to plane a BUNCH of 16’ Doug Fir recycled planks to floor my office I raised my planer (Ridgid lunchbox) up to where my 11’ workbench served as the outfeed table. Roller stands work OK for the infeed side but are a PITA on the outfeed side as they are constantly tipping/falling over, getting pushed around.
