Hi Kevin. All of the biscuits that you listed are based on the same standard thickness. That said, I have found huge variability in the thickness of biscuits. This is due in part to different manufacturing tolerances, as well as seasonable humidity variations that can dramatically change the fit of the biscuits in the slot. Generally what I’ve found is that when biscuits are loose, they still swell up and fit snugly in the slot after they have absorbed some glue. You can test this by soaking one in water and testing the fit.
In spite of all of the variability of fit, I have never had a problem with biscuits. That’s not to say that it wouldn’t be possible to have a problem, but I’ve had good luck in my 25 years of biscuit joinery.

My jointer does the different sizes, 0, 10, 20 but it’s th thickness I an concerned with. My jointer seems to cut thicker then my bicuts are. Comments? Are there thicker biscuits?

Jim,

Most biscuit joiners allow for an adjustment to be made to the depth of cut in order to allow the use of multiple sized biscuits; #0, #10, and #20. All of these biscuits are the same thickness. If yours supports only one size I’d suggest consulting with the manufacturer or the manual to know the biscuit size. #20 is the most commonly used size.

When I make a practice cut the physical width of the opening measures .230″. What size biscuit do I need for this opening?

Hi Zach. It would not be recommended because there wouldn’t be much biscuit protruding from the slot after you slipped it into the first side, but if the biscuit protrudes at all (which I think it should) it might provide some aid in aligning the joint, so perhaps some slight value.
Thanks

The arbor is 22 mm or 7/8″.
