Ideas on removing planer blade

[Osric]

I have a Jet 15" planer that is giving me some headaches.  I'm going to assume that planer blades are pretty much removed the same way...get to the blades, loosen a few bolts and the blade comes out.  If this doesn't make sense to you, let me know and I'll try to explain it better.

In any case, my planer has 3 blades secured by about a half dozen bolts each.  Two of the blades I've removed pretty much without problem.  But on the 3rd, one bolt refused to loosen...my using some cheap chinese wrench probably didn't help matters.  In any case, by the time I got done trying to remove it, I had pretty much stripped the bolt so it is too round for even a good wrench to get ahold of.  So I'm stuck with 2 blades removed and one pretty well stuck in there.

I've tried levering it up for the other corner (the bolt that is stuck is one of the last ones), but can't get anything underneath it that is strong enough to lever it up.  I've tried cutting the bolt off with a recipercating saw, but there isn't enough room for the blade to get to it without it bouncing all over the place.  I've tried cutting it out by hand, but I don't seem to be making any progress by doing that either.

Anyone else have any ideas?  I'm about out of them.

cut it with a cold chisel. It's most likely hardened steel and should snap fairly easy.

Vise Grips.  If you have the ones that have the long nose you may be able to get to it a bit better.  A similar thing happened to me when changing the knives on my portable planer.

Oh, if that does not work, use a cutting wheel in a Dremel tool to square up a couple sides to get a good bite.

dremel is a much better idea than mine.

If only I had a dremel....guess it's time to buy a new tool  :D

I second the Dremel...make sure you wear goggles as the cutting discs are easy to break if you even get them in a little bind.

Once you have one you will find all kind of additional uses to justify the purchase.

Double up the discs, they last a bit longer.

You could also get a $10 pneumatic cut off form someone like harbor frieight.  Might be a little easier.

picked up a dremel at the big box store.  Nifty little tool.  Cut that bolt out in about 5 minutes.  I'm sure I'll find other uses for it as well.

thanks for the help
