Topic tags/keywords: biscuit joiner plate ff biscuits biscuit joiner

Just got A P*C biscuit joiner. I’m a newbie to this tool.

I understand that the FF biscuits are used on small pieces, such as face frames. From what I can tell, you can’t really use a biscuit joiner on stock that is less than 3/4 thick. Is that correct? So your face frames would be made of 3/4 thick material?

That 2” blade is quite pricey at about $60. Any better sources for that?

Thanks! Gary

I’ve never used a PC but on my Freud, you can adjust the fence for different stock thicknesses then register the fence on top of the material. If you register the base of the joiner and the material off the same surface instead of using the fence, it cuts a slot centered on 3/4” material.

I have one of the original Porter Cable biscuit joiners (thanks to “norm”)

I use the stock cutter and the smallest biscuit I use is the #0. The cutter makes a 1/8” kerf (I think). I’ve used it on material as thin as 3/8” with no problems.

My PC 557 came with all the parts required to use the FF biscuits (including the blade but not including the biscuits). Never used it though. I use the Kreg for face frames.

Your 557 should come with a clear plastic spacer that clips to the underside of the fence. This allows the jointer to work with stock thinner than 3/4”

It will work with smaller stock, you need the plastic piece that Mark Mentioned. I’ve never seen any aftermarket blades for the FF biscuits, though the full size aftermarket cutters are available. If there is an aftermarket FF cutter, I’d be interested in one as well.

Thanks everyone for all the great info! Guess I need to read manual on that plastic piece. Didn’t seem to find anything on YouTube.

Thanks! Gary

Yes, you can use it on less than 3/4 stock. FF biscuits are dinky. I had a pack of them for 15 or so years and never found a use for them so gave them away. #10 is the most common size I use followed by #20.

I think FF biscuits are too small to be useful. I assemble face frames with pocket screws, then use the #20 biscuits to attach the frame to the cabinet. Works great.

In applications where the top of the frame is hidden, you can use #0 biscuits and trim off the excess. In cases where you have 2” wide rails and stiles, #0 biscuits will actually fit with careful layout (they are 1.75” long).
