TS55 saw blade for cutting biscuit slot?

[NAS]

Is there a bade for the TS55 (or any circular saw) that has the correct kerf for biscuits (5/32"??)

I was thinking that an easy way of joining plywood panels at a 90* angle would be to cut a kerf with the track saw where you want the joint and then cut regular biscuit slots in the edge of the joinging piece wherever you want (because you have a continuous slot to receive them)

Ideas?  Thoughts?

There's no blade made by Festool with a 4mm kerf.

You could easily do it with 2 passes of the standard blade though.

Other than helping with alignment, there is no big advantage to using biscuits.  You get a bond just as strong with simple full-edge gluing.

Sooo, I guess my point is, why bother trying to rig up a TS55 to cut a biscuit-sized slot? If you want to aid in your glue up by using a long spline, then just cut a normal kerf  the full length of your board, and create a long spline that matches the thickness of the kerf.

I have no clue how you get that impression. With biscuits or dominos applied you get a whole different picture of how the forces work on the joint. With a normal glue joint the forces only work in 1 direction. With biscuits you also get forces to work across. And the glue surface becomes bigger. Really, biscuits help a lot.

Also, the blade diameter is too wide for biscuits.  You would have a very excessive groove that would probably negate the use of the biscuit.

Don't know if this will help, but...

Years ago, I bought a slot cutting bit for my router.  It worked ok, but I always routed slightly longer grooves than needed to make sure I had enough "play" for alignment.  Yes, I could have made a start/stop jig, but I was in a hurry...

Can you not use a router ie 1010 on a rail with a 4mm bit, if not just ue the TS55 and move it over by 1.8mm for the second cut thats if the kerf is 2.2mm.

As Wood_Junkie said, I too only use biscuits for face frame alignment. I got lazy years ago doing cabinets so I use a slot cutter in my router and I cut a groove all the way around the edge of the cabinet. The I use the plate joiner to cut a few biscuits in the face frame and you are good to go.

I do use my Domino on smaller cabinets...

I also do face frames like Ted says.  A continuous groove for the biscuit...  I was trying to apply this concept where you can't get the slot cutting router bit.  When I do face frames this way I only use biscuits for attaching it, @ about 6" oc, and glue and clamp overnight.  You just have to basically fill the entire groove with glue...

A plung router would be good too, just don't have one, yet!

hey guys, i used to fiddle with a ton of different joining techniques and in my opinion the best one for me at least is pocket screws, when i'm joining faceframes pocket screws are instant, no glue needed but i recommend it, you can instantly sand them and slap them onto your box, i deal a lot with veneer countertops with wood edging, i use the domino for a flush joint but i pull it together with pocket screws especially when it's a inside corner top where there is no way you can get clamps in.
and i also used a router bit to make biscuit joints, 20 bucks for the bit and already had a router.  better then spending 250 on a buiscuit joiner
