Topic tags/keywords: question planer

I bought a new Grizzly 15” planer with spiral cutter head and have finally got it assembled and up and running.

I was initially getting chips along with marks from the in feed rollers but adjusted the roller height as instructed and that problem went away.

My problem now is chipping. See picture with some poplar.

It is not the feed rate and is does not matter which speed I use, I still get the same outcome. Happens on some cherry as well.

I feel fairly confident I have the in feed and out feed extensions properly seated/aligned.

Anyone have any ideas what could be the culprit and a solution? My next adjustment will be the chip breaker but I can’t see how that would matter.

Any help is appreciated.

Happy New Year

A few of those spots look more like dents than chips to my eyes. Do you have DC hooked to that planer? Without it, the chips can come back around and get pressed into the wood by the outfeed roller. Some of those look like chips as well, and I’m not sure I have an opinion on them. I might have said it’s just the nature of the wood, but you indicated it’s a problem with some cherry as well.

Have you tried very light cuts for the final 1-2 passes? Limiting the depth of cut will help to minimize the depth of the tearout.
The grizzly spiral head does have a staggered design (limits noise, increases blade life with carbide etc.) but it is not really a shear design like the Shelix and Laguna heads. Grain direction matters too. Send the board through in such a way that the board feeding into the planer feels smooth as it passes under your hand.

That said, I have NEVER had poplar tearout on even my straight blade planer. I would not be happy to see these results from a spiral head. Cherry can get tearout, especially if it is really dry, or has wild grain.

I think I may have figured out a solution, at least it looks that way.

The manual says to have the chip breaker 1/4” from the head but after adjusting it to that tolerance I still had some chips. When I move the breaker closer to almost 1/16” of an inch the problem was greatly reduced….very minimal.

I did some searching on the web and saw comments about getting the chip breaker as close to the cutter head without touching it.

Fred, I do have a Delta DC hooked up to the machine.

Yeah I know Pinto it is not like a Byrd. I knew I was still going to have to run my boards thru the drum sander for final thickness.

I will update after I run more thru it…..for now I need to get the Jointer open and assembled. I hate cosmoline.

Heck, I thought I was the only one having these problems. I cleaned and cleaned to get shipping grease off of cutter head and all, then I got ahold of Grizzly service rep., he told me to get old hard 2 x wide and run it thur till nothing left of it, that would heat up cutter head and get rid of any remaining grease and shine up the cutter head. So if yours is new try that. Then I was still getting marks in planed wood, so he told me to check chip breaker and dust collector. Chip breaker was in best position, I tried all the way in against cutter head, and all other positions. Nothing worked, so then I upgraded my collection hose to 6” from 4” ,still no luck. I then figured out if I ran hard maple thur my planer it had none of the marks on it that the soft wood did. I then found that the marks were the dust collection lacking to cleanup chips and planer rollers were pushing chips into wood making small random dents, the softer the wood the worse it was. I then did a substantial filter upgrade on my cyclone, in the meantime I also ran thousands of board feet of material thur planer and my dent problem kind of took care of it self. I still get a few marks on soft wood. I have run a lot of wood thur this planer and have not rotated cutters, it is a champ, with a softwood problem. Good luck, if you figure any thing out, please pm me.

I have cleaned and cleaned as well bugz. It does seem to be better the more I run thru it.

I removed the cover and hit it with the air compressor while it was spinning. This cleaned it up a little more.

I desperately need the filter upgrade on my DC….maybe a Wynn is in the near future.

I really like the volume level this thing has compared to my old Steel City with knives.
