I am in the process of building an entertainment center and will be adding a face frame. I want to attach the face frame with biscuits but I dont want to go through all the trouble of marking all the slots in both the carcass and frame. I want to use a slot cutter in my router to cut the slot in the carcass and a biscuit joiner for the frame. My question/problem is the cutter for the joiner is 5/32” and the slot cutter I have is 1/8”. I know its only 1/32” difference but the biscuits are fairly snug and I am afraid that when I add glue and the biscuits swell they will split or make the plywood bulge. Has anyone used a 1/8” slot cutter for biscuits and what was the outcome?

Pat…..I am trying to cut down the labor time involved. I had thought of sanding down the biscuits and even considered making 2 passes with the router to widen the slot. I guess I could break down and spend $15 and buy a cutter…...Novel idea huh?

I guess I will make a 2nd pass after a 1/32” adjustment. I was just trying to save time. I did order another cutter for the next time though.

Before buying my biscuit joiner I had an attachment from sears to fit my router and I had a smaller cutter and it worked fine, I find that with my biscuit joiner the biscuit is a little loose.

Ken, Why use the Biscuit Jointer at all? You really don’t need it. I’ve been attaching face frames for over 20 years and have never found a real need for one with face frames.

Yeah, I know the reason that they advertise, I just don’t agree with it all that much. I bought mine about 14 years ago and I’ve only gone through maybe 500 Bisquits total. I think they’re very inconvient for face frames.

John….. I dont want to use brads or nails to hold the frame on. I am gonna paint it and dont want to go thru the hassle of filling the holes and sanding etc. The biscuits will help with allignment and keep a nice clean look and I wont have to worry about the wood filler popping out later.

I recently built a kitchen full of cabinets. I used Biscuits to join/align the bottom shelf and the face frame. the sides that werent visible I used Kreg screws and nailed the top because the crown molding would cover the holes
I wouldnt use a slot cutter ina router for half your setup. Bisciut cutter for both face frame and carcas slots are neccessary because the biscuits swell with glue and do a great job holding. a thinner slot cut with your router will pucker the ply on your carcass.
Good luck. There are no real short cuts that wouldnt sacrifice something in the long run.

I have ordered a 5/32” slot cutter. I am thinking it will help to speed things up a little on this and other projects.

Ken, I never use nails, staples, screws or any other metal fastener to attach face frames, ONLY GLUE. The right glue and prep work is all you need.

I’m going out on a limb here but, you have spent more time discussing how to get around marking the slot locations and cutting them, just sharpen your pencil and go for it… ;)

This may be insignificant but, here goes anyway, if you cut a full length slot versus the biscuit slots then you are reducing your glue surface by about one third.

In any event…if you do much bisquit joinery you’ll need a slotter the right size whether you use it for long slots or for multi tool set up for face frames etc. Good choice getting the right tool. I typically use 2 bisquit slotting jig set ups simultaniously to speed up the face frame process. One for the styles on the router/shaper table, one for the rails with a table surface mounted bisquit jointer. It saves time and reduces mistakes.
