CNC Design & Fabricate a Worktop

Good morning. I'm looking to turn an adjustable height work table into a micro jig match fit style work station with mft style 20mm dog holes. Does anyone know anywhere I can find someone that will design and CNC cut something like this from a sheet a plywood I plan on laminating with formica? Any businesses that can do this sort of thing would be greatly appreciated. I'm in the southwest Charlotte area, but willing to travel a reasonable distance. Thanks in advance.

I have heard discussion of a hand drill jig that rivals CNC accuracy for the MFT table.
A couple folks here have them.

There are a few guys here who have large bed CNCs who can cut those for you. There are folks on Etsy who have customizable files for a few bucks.

You could message them and tell them what you need.

I've seen a few jigs, but they seemed pretty expensive.
If you have a plunge router that accepts guide bushings, those templates are relatively inexpensive.

We have a "community" router template, but I don't know who has it (@Hmerkle will have to chime in). Also, @chris_goris has offered to make tops on his CNC in the past

So, instead of insulting me why not explain why a jig can not be as accurate as a CNC? I have to assume that’s what you mean since there is no indication of what exactly is laughable.

a jig to drill individual holes? referencing one to the next? ever hear of cumulutive tolerances? My CNC has a repeatable tolerance within +/-.002 inches. Thats between every hole ans from the farthest apart. Drilling one hole and then putting a pin in that hole youve already lost. Chances are , your hole wont be round and then the pin that goes in it to locate the next one has a diametrical tolerance (slop) and it just multiplies.

Oh boy. It's gonna be a machine accuracy vs man made accuracy thread now right?

There are arguments on both sides folks. You start off automated wrong, or have a fault somewhere in the middle of the process, and everything goes haywire. You manually set a template and after a few holes see an issue and have the ability to adjust on the fly. Horse a piece honestly. Better to argue about the best way to square up a cabinet stile than to argue automation vs a craftsman using a template.

I’m really surprised your CNC is rated +\-.002. Not saying it can’t do it, just surprised it is rated at that. The million dollar Amada turret punches I worked with were only rated at +\-.004. I believe they actually performed better than that, but I think it was in the machine manufacturer’s interest to pad the rating. Either way, it’s all about tolerance stack up when putting stuff together. Wood is pretty forgiving, but it’s nice when parts are right and it all comes together.
