Topic tags/keywords: planer question

So my 735X’s mechanism is jammed.

The repair person who fixed it a few months ago told me (on the phone, without having seen it) that it’s rust – which may well be true, but it’s been covered in a screened-in porch in Los Angeles. He says it will need taking apart and cleaning… which was $100 last time, but all things being equal I’d rather not spend that again.

Anyway, it was working fine a week ago, so if it’s rust it happened all of a sudden. I have a feeling it’s out of alignment again, but this guy does have a lot of experience and seems to be very good.

Question: should I try WD40 on the poles and chain, or will that just destroy good grease along with bad stuff?

TIA

Bonus question, while my mind is on the subject:

The outfeed extension wing thing on this machine is missing springs or something that hold it level, so it’s a little low and I end up holding it up a little to support the wood as it exits.

With regard to snipe, is that worth fixing, should I bother with a “sled” as an alternative, should I just live with it…

The subtext is that the depth gauge will then be off a little, even though I do know how to add 1/2” or whatever.

My first impression is that it’s gonna cost you a minimum C-note if you take it in anyway, so why not just try the WD40 on the posts anyway?

What was wrong with it a few months ago that you had to get it fixed? (Maybe you discussed this in a previous post from back then and I haven’t seen it.)

Is there really grease on the posts?

Don’t go crazy, but see if you can gently get the WD40 to soak into the minute gap between the posts and the mechanism and see if you can get it loose. If successful, you can then clean the posts with a fine polish of 0000 steel wool and then lube again. Try to avoid getting any of the WD40 on the feed rollers.

That’s how I clean the posts on my Delta planer (going on 20 years old, and it’s never been to the shop).

Thanks Ray.

I bought the machine used, knowing full well it would need to be taken in for repair if I couldn’t do it myself. it was the same problem, only it was misaligned then, and because of what the guy said + the fact that it went bad without being touched, I’m skeptical that it’s the same cause this time.

Your estimate of $100 is spot on – that’s what it cost to have repaired. But it was still a good deal ($250 + $100), and the machine really does do a great job.

I use dry lube on mine.

Ah, good idea. I have a can of that stuff that I bought for something similar. Didn’t think of that!

Thanks.

FIXED.

It was just sawdust gumming up the works. I blew it out like crazy with a shop vac, then used a dull knife while cranking it (so it turned) to loosen jammed sawdust that didn’t blow out.

And then used the dry lubricant. Why not.

Now it’s practically begging me to raise and lower it, it moves so nicely. Very satisfying. :)

Kids, do this at home: blow out your thickness planer after using it.

Did I mention how satisfying it is?

Who would have thought turning a crank would be so much fun.

I was just getting ready to say – keeping these things really cleaned out is imperative. My 734 gets fully blown clean each time I use it. Actually almost all my power tools do…dry lube will work for a good while but not forever. Setting aside some time for multiple tool maintenance makes the very next shop session really fun…

Don’t use steel wool to clean the leadscrews. The debris will get in the bearings and is impossible to remove.

Use a green Scotchbrite pad instead. Its tough enough to scour but won’t leave destructive steel lint.

Makes sense, Bstrom, especially if like me you’re not using your machines every day.

While I don’t know what leadscrews are, I didn’t use anything to clean this thing out other than air and a dull knife to knock loose trapped sawdust.

But regardless of what leadscrews are, that sounds like good advice for many applications.

Have your say...
