I just bought what I thought was a pretty good deal. About a 15 year old 2 HP 15” Grizzley copy (Grizzley manual is identical to this planer) Looks like new, very little usage. Running a piece of cherry thru and anything more than a 1/4 turn bogs down and stops. I thought the belts may be old or warn and slipping but that is not the case.

Doctors out there… any diagnosis or am I just biting off more than the machine can chew? I don’t think so but stopping???

I think a lot of guys try to go in 1/16” passes, im not sure how thick a 1/4 turn will get you. Are the knives dull? Try using a little paste wax on the table as well the can get kind of pitchy, same goes for the rollers.

I did a thorough clean and wax job. I will try and see how much the scale says I am trying to take off.
The knives seem fairly sharp with a good clean no line surface.

hmm .. youd think a 2 hp planer would chow away at it. Im sure someone out there a little more seasoned than myself will have the answer. I wonder if its electrical … try LJ member topamaxsurvivor if you dont get any more luck hes the local electrical guy.

Most planers I’m familiar with (except for BIG professional models) are designed to cut up to 1/8” at a time.
Did you mean,” more than a quarter turn”, or,” more than a quarter inch”?

We recently upgraded to 7 hp planer and I can take a full 1/16th off per pass without any struggle.

Before this planer I spent the last three years using a 3hp 15” jet planer. That planer would struggle at a 1/64th ”, or a 1/4” turn of the handle. No matter what specs say, taking a full turn (1/16”) is just too much for a smaller 15” planer, or at least that was the case for my 3hp jet.

I just think you will have to lower expectation, or upgrade.

I have a rigid 13” planer and had a similar problem. Until I changed out the blades. It was amazing. Cuts like butter now. One thing I noticed was that the old blades “looked” sharp. Turns out they weren’t. I can cut 13” wide hardwood 1/32” deep and not slow it down now. Where as before it would really bog down and you could tell it was really struggling. Just to be fair though, I see you’ve already done it, but I also cleaned the rubber wheels with alcohol and waxed the bed. I also double checked to make sure the in-feed and out-feed tables were in line with the bed (very important). Hope this helps. If it’s seen any use or you’re not sure, I’d sharpen those blades or replace.

I must admit I did not change or sharpen the blades. The cut looks OK, But I guess I cannot judge whether they are sharp or not by that. I will do the blades and hope that is it. If not at least I will be sure the blades are sharp.

I am kind of surprised to hear people having problems with 15” planers bogging down like that. My dw735 13” planer doesn’t bog down at all when taking 1/32” cuts and I have taken some cuts deeper than what is probably “recommended” when I need to remove a lot of material and had no problems.

First thing I would check is if the knives are dull. I got my planer second hand so I didn’t know how much use the blades had on them. I flipped them around and noticed a big difference. I don’t know if you can do that with all knives but it would at least be worth looking into. If you can, then that would be something you can test without spending any money.

Other recommendations (waxing the table and cleaning the feed rollers) are also good things to check. Though in my experience, dirty feed rollers won’t bog the machine down, it will just present problems getting the workpiece to feed properly.

Mine was bogging down pretty badly (and the feed rollers weren’t pulling well at all). I popped the blades out at the suggestion of my dad and they felt just as sharp as the reverse side (when dragged against my finger or something). I figured I’d try it anyway, and it performed 10x better. My money would be on dull (enough) blades

My vote is also on the blades being dull…. I have a 3hp Mini Max planer and it started bogging down and stopping once when I was plaining some red oak… Got the blades sharpened and it made a world of difference… Even if they feel sharp they may not be sharp enough.

My new blades should arrive today. After I get them in I will update. I also think it is the blades. Examining them with a magnifying glass showed them to be a bit more worn than I first thought. Now on to the job of change and setup.

Brian, it sounds like you have about the same planer that I recently acquired. Mine’s a Grizzly Model G1021. Due to factors inside and outside my control I haven’t fired it up yet. The previous owner had the foresight to stuff the manual inside the dust hood.

I’ll quote what may be pertinent: “There is a 1/16” limiter that is provided to limit the maximum depth of cut to 1/8” on full 15” planing. This limiting clip can be removed and a 3/16” cut taken provided that the motor is upgraded to 3 H.P. or full width boards are not planed.”

Like I said, I haven’t even turned the power on this thing yet and I have zero experience with these machines. When I do fire it up I’ll probably try, at least initially, to follow those instructions. YMMV.

On edit: Never mind. Where I thought you said quarter inch I see you said quarter turn. I blame it on slow caffeine absorption.

Just another thought – – – -
I would like to remove the drive belt and try turning the rotor by hand. If there’s a sticky or dry bearing in there it could add to the the situation.
