Hello, I wanted to make 1/2 PVC french cleats using my CNC router (( Colex Sharpcut)) because using the table saw is very messy. I found a V groove bit that cuts at 90 degree angle ((Onsrud 37-87)) but it requires a 1/2” collet which I dont have. Does anyone have a better idea? I can only make french cleats on CNC because again the table saw is very messy and we make alot of those french cleats.

at best you will want to use a finishing pass.
The debris from the harder material will cause striations on the softer.
It makes sense to put acrylic facing up.
However, you can specifically orientate your lasers how you would like.
Have you ever tried cutting just above the adhesive layer with the acm up to size first and then cutting the acrylic oversized.
Clean bit and then run the finishing pass to size.
Sometimes you have to do the best you can on the machine with what you have so it is good to have ideas and options.
So with a nice DLC coated bit you can skim pass to the finished pass.
It is better with 6mm or 1/4 bits so the bulk of the debris can "evacuate" the cut.
you might consider an offset with a smaller bit to increase the size of the channel around the cut for the vac.
Your adhesive is another wild card.
Depending on the type you will have various results from chips binding.
If you are able you can mist some alcohol to loosen the bond on debris and if you dont have a tool changer system youll want to clean the bit prior to the finishing pass.

Hi Sam, we just finished a batch of French cleats using our table saw and it wasn't very messy. I'll check to see what type of blade our Facilities Manager used. Like you, I would definitely prefer to use our Colex rather than rely on him making time to assist my wide format guy with this type of project. I'd ask Colex for best practice on this type of project.

Or go to Brooklyn Hardware Manufacturing and buy some panel clips.

If French cleats are something that you use often, why not just take a couple hours and cut a bunch of them and store for later use? Then you can make a mess one time and have a large supply? Or like Johnny Beat said, buy some aluminum z-clips…

What's your max collet size? Toolstoday carries a 1/4" collet V-groove that should be large enough: https://www.toolstoday.com/v-5713-45722.html

Wow, I forgot to come back to this. Apparently our Facilities Manager just used his table saw at a 45 degree angle to create our French cleats.
thank you.. I found the 1/2" collet and started cutting french cleats on Colex. I forgot to check this thread lol
