Thread: Mystery part on Jointer

Just remove it when rebating.

It's not removable!!

Can't be sure from the photo but is there a join along the length of the pin? If so it is most likely a roll pin and should be removable, you might have to work at it a bit.

If you get some pliers at the base (first put slim piece of material maybe ply on the bed resting against the pin, this will help protect the bed) of the pin and apply pressure the pin should lose it's shape, thus making it more loose within the hole, you should then be able to use the pliers pressing against the bed of the machine (for leverage) to work the pin out.

I think its where the spring loaded guard should attach to.

The big hole is where the spring guard goes in. I took the guard out to show the other part in red.


And... I already tried with pliers to rotate that mystery part and it does not come off. Also, as I said that part is not present in the exploded view in the manual.

Sorry, I'm not sure what you mean by a join along the pin. The "pin" is not really a pin, it's like a cylinder that is like a C profile in horizontal section and it stopw the guard from rotating too much out (pretty useless feature IMHO). And it does not appear on the exploded view in the manual of the jointer. If the only purpose was to stop the guard to rotate too much I cannot understand why they did not put maybe just a screw the way they do pretty much everywhere.

The Carbatec jointer at the men's shed has a roll pin in that location that stops over rotation of the blade guard. It has to be removed to use the rebate function. The roll pin is a press fit into an unthreaded hole. It needs to be pulled straight up and out (persuasion with pliers as per Camelots suggestion is required) Do not rotate it, it does not unscrew. To replace it needs persuasion with a tack hammer.

As an aside, the straight knife cutter head was eventually upgraded with a segmented head and now the rebate function doesn't work. The edge of the cutters on the outboard side are inboard of the edge of the body of the head.

If you're hoping to joint wider boards than what your jointer is designed for ie a 8" jointer can only joint 8" boards. You're going to be disappointed with the results.
Also i've never used my jointer to do rebates, there are so many other tools that can do that job more efficiently than a jointer, not to mention the setup changes required to change between the two modes. So i'm not sure why anyone would bother with this "feature" on a jointer.

That is similar to what my guess of the function. Some 'gentle' tapping from the back with a sledgehammer did the trick. It would not go back in as it would be much worse to come loose while jointing ad ending in the head than anything that can happen on a overrotation.

Maybe I can't train a choko vine over a sh.

Once you have the pin out you can always tap a thread to allow you to put say a small M4 bold into the hole for easy removal when you next want to rebate.

Regarding rebating have you sharpened the knifes/blades at the end, this would give you a better finish

Yeah, maybe I'll do that as it sounds like a good idea.
Sharpening blades sounds like something I'll attempt once I'll get more chummy with the tool.
