Topic tags/keywords: jig question resource tip trick router finishing veneering

I’m making a grid surface that will accept T-bolts. The dimensions are 29×29”. I’m going to have t channels every 5 inches. Horizontally and vertically. I haven’t worked a lot with laminate or formica so I’m wondering- is it better to route out my grid first with a 1/4” endmill for the majority of the channel then go back through with my t-slot bit to finish the slots…
Then adhere the formica to the surface and flush route the channels with my formica flush bit, or

Adhere the formica to the surface then put the surface into my cnc and route everything through the already adhered formica ?

+1 on Laminate first. Then hog out a groove with a straight bit first, then use the T-slot bit.

If you are going to use your CNC, make sure that your tool paths enter and exit from the ends with the T-slot bit. Not all CNC software understands undercut bits so you may have to force it to do it. Might be a good idea to test the paths with an air cut first. (EDIT to add:) You might do a practice slot on some scrap first too.

+1 Formica first then route. I’ve done it both ways and the results were the same and doing the formica first is less work.

As others have said, Formica (or other plastic laminate brand) first. Easier & quicker in the long run.
