so I bought this jointer off a guy on craigslist for only $200. Its a Sunhill. He said the majority of its life has been sitting in storage – and it showed. I had to get a lot of rust off of it – mostly surface rust, thankfully. Everything works great, except I can not get these knives out to be sharpened and realigned.

I’m assuming in order to get the knives out (there’s 3 of them) I need to get the bolts loosened…as shown in the pictures below. I can not for the life of me get these bolts to loosen. I’ve got the right size wrench. I’ve tried WD40 and Liquid Wrench with no luck what-so-ever. The bolts are starting to get stripped from trying to loosen them….

Am I doing this wrong? Is this how I get the knives out – by loosening these bolts??? I need some thoughts, or ideas. Its getting really frustrating!!!!!!!!

PLEASE HELP!

You can get a cheap torch at Home Depot for $20. Have you tried spraying a lubricant and letting it set overnight? One of my friends is a boat mechanic so a lot of stuff he works on is rusty and impossible to loosen. A trick he showed me once is to slightly tighten a frozen bolt before trying to loosen it. Doesn’t seem like it would make any sense but I have seen it work on otherwise stuck bolts.

the bolts ‘lossen’
when turned into the knives

i have made that mistake before
(looking down from the in-feed side
turn them towards the fence)
more liquid wrench too

are they left handed threads? Try tightening first.

I’m not sure which way the bolt comes off….maybe i’ll try and get a better pictures of the threads. I’ve tried turning them both way, and nothing budges….and on top of that its starting to strip the bolts….

You tighten the bolts to remove the blades…..

the next thing I would try is to take a good heavy punch, and smack the bolts. Not hard enough to break them, but hard enough to possible break them loose.

The other observation is: if I was doing it, the penetrating oil (Liquid Wrench) would be oozing from everywhere. Soak those suckers good. WD-40 isn’t a good enetrating oil in my opinion.

How long have they soaked? I’d have continually soaked them for a day or two.

Also +1 on the heat. It doesn’t take a lot, they don’t have to be cherry read to be effective.

If everything else fails you can always cut the bolts off with hacksaw or grinder, remove the knives and repair or replace the shim bar.

I had them soaked in liquid wrench for about 30 mins.

Does anyone know which way the bolts need to turn so I don’t strip them anymore. Patron said push the wrench towards the fence?

In my opinion 30 minutes is not anywhere near long enough.

I would agree with pushing toward the fence. Thats assuming they are threaded into the shim bar, which is what the picture looks like.

Dakremer,

If you’re still struggling with the bolts, try some Bluecreeper

I’ve found that this is the BEST penetrating oil product I’ve ever used (and I use a lot of different ones in a twenty year career in the Navy as a shipboard maintenance electrician…).

Soak the bolts down with this stuff, wait a while for it to work and that’s all it takes.

Good Luck!

Be Careful!

tightening them ‘down’ (clockwise)
actually loosens them up

when they are ‘loosened’
(or turned counter-clockwise)
they get tight against the cutter block
and push the blades tight
to the other side of the block

it’s all ‘backwards’
but it works that way

chrisstef has done what i did too
i have had to grind the ‘cheeks’ of the wrench
to fit into the tight space there
those thin stamped wrenches don’t work for long

and a tap with a hammer
on the end of the wrench towards the fence
can jar them

Doug, Liquid wrench is pretty old school. They have some much better products out today that penetrate rust. I soak them overnight in something like PB Blaster. the best one I’ve ever used is called Cyclo but I can’t find it much any more. They look like they got rusted in. I think most of them are right handed so you turn them like you are going to screw them into the plate or or tighten them. What they do is back out of the plate and against the knives- like jack screws that lift things. ...........Jim
