OK, I was thickness planing a piece of wood yesterday and when it came out it had a groove the length of the board. I opened up the back of the planer and checked out the blades. Underneath one of the blades, is a piece of wood jammed in between the blade and the drum. My initial thought was to remove the blade, clean out the debris, hone the edge and put it back together. I was going to do all the blades while I had it apart.

Problem: A couple of the set screws, holding the blade in place will not loosen. I’ve either stripped the allen wrench round or stripped out the set screws, or both.

How do I get the set screws out and how do I keep this from happening again (debris between the blade and drum and also the set screws seiizing up)? I’m perplexed to say the least. BTW this is a Ryobi bench top planer.

Have you tried an easyout?

A light tap to the screw heads with a hammer can help break the grip of the thread. Once you get them out, lube them before putting them in…I’d also look to replace the screws with better quality hardware.

If all else fails, use the smallest cold chisel you have to make a slot in each screw then use a slotted driver or, continue to use the chisel gently taping it in a counter clockwise direction. If it doesn’t move after the 2nd or third tap, tap it firmly clockwise once and, then try counter clockwise again. All you have to do is break the bond. This technique works with frozen bolts of all types.
I hate to say this but… As soon as you can. I recommend the new DeWalt or even the Ridgid. I’m sure you can sell this one for part of a new… You owe it to yourself.

This might sound a little nuts, but if you can find a can of something (canned air maybe?) that comes out REALLY COLD you could shoot it into the allen wrench hole and maybe shrink the metal of the set screw and quickly pop it out.

Better that tearing up the screw.

Good luck!

I usually try these in this order take a brown paper bag (just kidding) I use some oil like knocker loose(not kidding) and let it set for as much as over night, then I give it a couple hard taps on the Allen or screws if not successful then I use some heat if then if no success I use a easy out or repeat the whole processes.
Most of the time I don’t have to resort to the easy out.

All good suggestions, except for the brown paper bag, LOL. I haven’t had a chance to get back out to the shop and try any of ‘em yet. Been trying to rebuild a crashed hard drive and get all my data loaded back in. I’ll let you know what worked. At this point since I’ve probably stripped them out, it will probably be the easy out method.
