Rigid planer

I have had this planer for 5 years and never had any issue with it. I recently ran some 8/4 purple heart and some 8/4 maple through it and there was no issue. Everything worked fine. After glueing up the maple and purple heart I was going to run it back through the planer. The first piece I sent through milled out just the way it was suppose to. However the second glued up section is not going through the planer. It immediately kicks it out of the planer as soon as the blades come into contact with the wood. I changed the knives, ran some oak through and it milled out the way it should. When I tried to send the glue up pieces of mapel and purple heart back through, it again kicked it out.

I have used hardwoods numerous times with no issues. When I run any stock through, I usually take only 1/32 or 1/64 off at a time depending on the wood I’m using.

Any suggestions.

Have you tried adjusting the cutting depth up and/or down slightly to see if that has an effect?

any residual glue squeezeouts on the glueup that keeps it from sitting flat? or that are sticking up into the cutterhead?

also which way is it kicking it ? back at you? or out the outfeed table?

Cutting Depth – I have tried adjusting the cutting depth. It either just misses the wood or as soon as it touches the wood it kicks it out. I tried the same procedure with the stock maple purple heart and it takes okay.

Glue residue – I see no glue residue at all. As it’s drying I scrape off what I can get too which is most of it. There is no glue residue where it is starting its cut.

Odd mystery!
Hope you find the problem and let us know.

is this an end-grain cutting board by any chance ( a big no no for planers)?
if not – are the grains between the gluedup boards reversed?

Rollers – The rollers are clean. I cleaned them when I did the blades.

End grain – Yes the final cut is end grain. If this is the problem, should I just sand it?

Honestly I am surprised this hasn’t happened sooner. As a point of safety we should not ever run end grain through the planer. This can cause damage to the planer not to mention injury to you….

I usually just sand the end grain… Far safer.

Are there anti kick back fingers on this planer?

um …. yeah… end grain should not go into a planer for the obvious reason you are experiencing. the good news are you are still doing well, and your planer seems to still be operational so consider this a lucky lesson.

end grain should be wither sanded flat, or use a router in a sled to flatten it

Yeah I’m good. Planer is okay to. I checked it out and milled out some other stock and it worked fine.
No kick back fingers on the planer.

Thanks for the help.

I think you have your answer. Sanding, it seems, is the way forward.

I asked about the kick back fingers as my planer is equipped with them and they stop absolutely everything coming back out the planer. I would have thought it would be possible to plane end grain as long as there was a spelch block at the back of the piece to prevent breakout, but without the anti kickback feature, it’s probably not worth taking a chance.

as said planners don’t like end grain actually they hate it… sanding… and more sanding needs to be done… I mean we are wood workers we love to sand :-)

Not so long ago, I used my Makita handheld electric planer to get the ends of two 8” walnut pedestals flat and square before mounting on the lathe. They planed up really well, much better than I expected with the electric planer. Couldn’t have done better with a razor sharp low angle block plane.
