Topic tags/keywords: planer question

Some might have seen a small gloat about a thickness planer I picked up for fiddy bucks. (Fiddy bucks = $50)

So let’s be honest. I probably wasted fiddy federal reserve notes. Sure… Their value is debatable, but they aren’t getting easier to come by despite their perpetually diminishing value.

I digress.

Anyhoo… It sounded good enough when I bought it, even after I repaired a gear with sheer ingenuity. Even when I planed some stock which was about two inches wide.

Forward to today, as I began planing a piece of walnut about 6” in width. Starts off well. Gradually a sort of chattering sound, perhaps a bearing, begins to become more present. By the time I had nearly surfaced one side of this piece, the noise was nearly constant.

I disconnected the drive belt, and the motor sounds smooth, albeit loud. These things aren’t noted for quiet operation, but the chatter was not seemingly in the motor.

I looked at the schematic online, which was not particularly legible, and it doesn’t seem to list bearings for the cutter head. Perhaps they are integral? Included with the cutter head?

Fwiw, the cutter head is discontinued.

Any thoughts? Suggestions? Reprimands? Insults? (I can take it.)

(I know… Go buy a new planer, or a more quality machine from CL)

Not to add insult to injury, but I Googled your machine and found this. Looks like someone else found the fix.

Sure looks like it has bearings.. part #1086894S (Qty: 2)

( found at ereplacementparts.com )

Try spinning the cutter head by hand (with the belt off) to see if you can isolate the noise. There is another bearing in the gear assembly along with some bushings on the gears and feed rollers that could also be the problem.

I might have to attempt a woodgears jointer build with this planer as the victim. Still… Bad bearings will still be bad.

Cutter head has to ride on something, so just tear into it. It sounds like an easy fix.

Thanks mr unix.. The blowup on the delta site wasn’t legible.

When I spin the cutter head by hand, it seems to turn smoothly with no resistance. It could be as you say. I did not want to tear that deep into it, but really, what’s the harm?

Feed roller chain drive maybe. Likely has sintered gears and
the teeth can chip off.

Thanks Loren.

Those seem to check out. All teeth present, no signs of excess wear. Operating smoothly.

I think I’m actually enjoying this.

So I went ahead and checked the brushes while I have it cracked open. They are looking nearly devoid of wear.

This planer did not look unused, so perhaps they have been previously replaced. When I opened one up, a considerable amount of dust had collected. The other was clean. (A healthy “pinch” of dust)

Could this cause a racket? I used the compressor to blow it out thoroughly.

The bearings for the motor seem to spin without undue resistance or any signs of chatter.

I guess I’m going to break open the motor housing and see if there is any more dust or other obstruction.

Since you already have it apart, pull the gears and check the bushings (plain bearings).. they could probably use a good coating of grease anyway. There is a bearing behind one of them also. Might want to go ahead and clean/lube the chain while you have it off as well. One last place to check would be the block bearings that the feed rollers are in.. and give them a good coat of grease.

Cheers,
Brad

I am doing as you suggest, MrUnix.

It makes good sense to lube the works. I would be surprised if its one of the feeder rollers, because they move so much slower. That said, it could just be bone dry and demanding attention. I had been reluctant to disassemble the feeder rollers. As I backed out the screws, it became clear that there are some fairly strong springs which apply downward pressure to increase feeder friction. It looked like it might be a PITA to get it all back together.

The planer is basically disassembled, so it would be a shame to not check. The further I go into this, the simpler it seems. Fear of the unknown is fear of nothing, which is the most crippling fear of all. Thanks for the help and encouragement, everyone.

Update: Success?

So I took everything apart, lubed any appropriate parts with grease, put it back together… Fired it off a few times… Let it run… And the chatter seems to have vanished. So it might have been yet another case of overdue maintenance.

I say “might” because I don’t want to jinx myself. (Not that I am superstitious, but Mr Murphy was very legalistic)

So thanks everyone!

MrUnix… Those block bearings seemed particularly dry. I think that may have been the culprit.
