Bit the bullet

[bigsteel15]

I just got back from my daily lunch trip to a tool store. House of Tools in this case.
I went in to LOOK at biscuit joiners and walked out the proud owner of a PC 557. I bought it because it seems to be the fave here and is half the price of the Lamello with most of the same features.
I didn't want to have a need for a biscuit size and not be able to produce the cut.

Now my questions.

What would be considered the most common size biscuit? HOT say they sell more #20 than anything. They look kind of big.
Most of my immediate use will be for corner joints on 3/4" plywood for cases.
I bought a mixed box with #20, #10 & #0.

I'd say I use #10 and #20 in roughly equal quantities. For 3/4", I mostly use #20.

P C has the smaller size called FF . They are smaller than "O" I think you might need a smaller blade in the cutter tho. The FF stands for face frame like for cabnets.

The PC should have came with the small blade. Easy to install if you pay attention to the instructions.
