Delta planer problem.

[Steve in VA]

Older 12" Delta Model 22-640.

Its been a good planer but is developing a problem in that while in operation the cutter tends to drift downward. Not much. 1 rotation of the handle is 5/64" and the handle walks through about 1/4 turn. Still I'd like to resolve it

The parts diagram doesn't point equipment towards any obvious worn or misadjusted parts but I may be overlooking something.
Thoughts?

First thought is that your elevating nut(s) and/or spindle(s) are worn enough that vibration will let them move.

My DeWalt has a carriage lock that you must release to move the cutter head and then lock. It does not appear that your Delta is equipped with a lock.

No, it does not have that. It looks like I need to find a way to increase tension on the threaded shaft.

Is there room for a spring for one or more of the threaded shafts?

I was also thinking along that line. I haven't pulled a side cover off to look more closely. It may be the way to go.

There should be a locking mechanism on the elevation to prevent that.

If there is, I can't find it. I've read through yhe manual several times and reviewed the parts manual. I don't believe this particular machine was set up that way.

There should be a black knob on the right side looking at it from the front. That should be the locking knob. Perhaps it is missing on your planer but that is what you need. Delta didn't make the planer, it was made by someone else and they put the Delta name on it. The one I had Delta discontinued parts but Ryobi parts would fit it.

Thanks. I'll go take another look.

No joy. Nothing that would lock travel. I'm thinking my best option is to make a friction washer under the handle to counter tendency for elevation screw to move.

That was the first small planer I bought in the late 90's.I used and abused the crap out of it.No lock on mine either.My only problem was that the potmetal housings would kind of swell up and seize on the vertical guide posts.It was never left out,but that thing seemed to be a moisture magnet.Eventually I found the moisture was coming from the green wood I was planing.Duh,took me years to figure that one out.Skimming off old PT was a big source of the problem.Blades got to be a little hard to come by for a while,then suddenly they were all over the internet,and cheap too.Finding the blade screws got to be a problem,and it was still so when I gave it away.

How about a Bungee strap that you could hook over the handle. That is what we ended up with on Daddy's Belsow planer. But then, we were powering it with a 5 hp. Briggs instead of an electric motor. So lots of vibration.

I'll chase that. Thanks

I think the problem I'm having is the model number is 22-540. There isn't a 22-640 shown and google was showing me a different planer. The 22-540 doesn't have a locking mechanism. I believe this planer depends on friction to hold the height. If the four posts the head raises up and down on are lubricated, you might clean the oil off as well as the threaded rod it connected to the handle. You might also drill a hole through the crank handle and several into the body of the planer and insert a pin to keep the handle from turning with the vibration of the planer.

I may well have a typo in the model number. I like the pin suggestion. Fortunately I've done the immediate project by holding the adjust handle while it runs. Plus I was planning really old, dry, hard oak.
