I recently purchased an old Powermatic 50 jointer from craigslist. The jointer runs nicely, but it was missing the cutting guard. Purchasing a replacement guard assembly would run about $70, and so I decided to build one myself for about 10 bucks. The porkchop-shaped guard itself is made out 3/4 Baltic birch. I embedded two sets of bearings in the guard that are attached to a 5/8 hex bolt, so it rotates sort of like a skateboard wheel. Extra washers between the table and the guard give the guard enough clearance for making 1/4 inch cuts (though I don’t ever plan on making cuts that deep on the jointer). A spring is attached to the back of the guard to hold it tight against the fence/material while still covering the cutters. I painted the guard red to make it look more appropriate.

Now I’m not scared to death by the jointer! ;-)

Very cool idea. I like that. I have turned away from purchasing one or two old jointers that I found because this piece was missing. I may not pass on the next one now that I can see how to make one. Thanks for sharing.

verry nicely made! i removed the guard from my jointer wich is one that lifts up over the piece, but it’s also a thickness planer and when i use it that way the guard hangs in the way. it doesn’t really scare me to use it that way, but i know im playing with fire
ill see if i can make one similar to yours for on mine! that system looks more practical.

This is exactly what I’ve been looking for.
In the UK jointer’s have a really crap sliding guard that in my mind is dangerous.
I’ve removed mine totally. Which I’m not happy with.

I hope you don’t mind if I copy this?

thanks Jamie

Hey , there it is !! Thanks for the flashback , Brandon : )
You did a really good job on this !
I don’t know if I would have thought about adding the bearings to it or not. Nice idea : )

Thanks! I’ve been looking all around for a replacement, and it never dawned on my to make a guard from plywood. Thanks for the idea!
