planning glued up boards?

[tlcneeded]

i have a dealt planner but, ive never run boards though it that has been glued together ( with the glueed joints facing the blades.) before i do it i'd like some input on it. blades aren't cheap.
thank you

If it's yellow glue... if you've already cleaned up the glue as best you can, it'll be a little rough on the planer's knives but not too bad unless the glue line gets wide. A good-fitting glue joint only leaves a teeny bit of glue in there.

If it's polyurethane glue, not to worry at all - that stuff stays pretty soft forever. Hide glue the same way, but a different kind of soft.

Don't run yellow glue through with beads of squeezed-out glue on the surface, though - THAT will beat those knives to DEATH.

If you've just used regular yellow glue, you'll probably be fine. Do know, though, that a LOT of glue through the planer will make some flat spots. Be sure to scrape all the glue off the surface that you can, too, that'll help

If yer done with it for the day, I'd appreciate it if you'd send it back... I miss it.

LOL!!!

suggested glue for using? was going to use gorilla wood glue.

[TDHofstetter]

That'd work just fine - and won't hurt the planer knives at all.

Honestly - if your planer knives are beat to hell and you are going to be doing a ton of sanding anyways.... lol - this sounds awful, but - does excess yellow glue matter? I think - no - just because, the blades are shot anyways, you'll never get the nicks out.... I still try and get as much excess off before planing - but - if the knives are nicked up pretty good.... I don't worry as much about it.

For instance.... when I make my end grain cutting boards - I do send them back through the planer a couple times - and yes - there are a ton of glue joints.... if my planer blades had just been changed - or were completely nick and scratch free..... I'd think twice about it.

Just like Zac, I've run cutting board glue ups through the planer quite a few times. I always clean up the glue (I like TiteBone III) with a putty knife before running them through.

Also, I don' wait too long before planing them - I figure the glue won't be quite as hard on the blades if it is not fully cured.

Everybody else has talked about glue, but I didn't see anybody mentioning tearout.

If your boards have grain running in different directions, it's possible you could get some nasty tearout in some parts of your panel. If you're planning to plane a panel, it's a good idea to consider the direction of the grain ahead of time and adjust your boards so the grain runs in the same direction, or at least make note of how you've assembled things so you know if the grain runs in different directions. If you know for sure that all the grain is running in the same direction - great! If not, I'd suggest taking small bites to start. You might even want to moisten the boards with a wet rag and let the water soak in for 10-20 seconds before putting the board through the machine. Doing one or both of those things can help mitigate tearout in some situations. Worst case, you need to find somebody with a wide belt sanding machine to help out.

thanks for the input i ran the boards today and they did just fine.
the water thing sound interresting im sure i will be trying that here soon too.

thank you
