That is fantastic work!
Do you do 30LPI?

Damn, just figured out where Upland is. :-(

I have a 07 FFL, it's ok to ship your firearm to our shop in the event that you live outside of driving distance or out of the state. 30 LPI is good and if that is what you like then great. However, I can assure you that once you see and feel 20 LPI you will choose that option. I believe this because I have had a handful of customers that initially wanted 25 and 30 LPI, but chose 20 LPI once they saw and felt the work.

Do do you do 30lpi? Or not?

Yes, if you wish to have 30 LPI then I am capable to do the job.

Looks like you've done this to more than one frame. Have any pics of the finished product?

Very nice! Can the checkering be taken all the way to the bottom of the frame?

Yes, I can machine all the way down the bottom of the frame.

That looks super sexy. I like that you are framing it too. Have you considered making jigs to allow for diamond checkering?

I don't think a Jig would get you there, it's easy to cut a groove around a radius space them out a given distance and then flop it over on it's side and do it again.

Creating actual diamond checkering of say 60˚ pattern would require a fifth axis machine Or at least a 3 axis with a fixture and some damn creative programing to eliminate odd looking starts and stops on the pattern.

That said I'd have to cut something to see how it would look and what would need to be done to correct it. And there are far better guys out there programming CNC's then I thats for sure. Just my guess. But it could be possible to kick it over on a jig get a cutter with the correct clearances and have a go at it.

I know you are right. I was thinking minimalistic, but it would have to be a complicated jig and obviously a different cutter. What popped into my head was a V shape cutter like a tapered end mill or a ball end mill if diamonds are to be super aggressive.

In the absence of CNC a two part jig - one part is basically similar to rotary table or a jig that rotates the frame, the other secured to Y axis for example camms or turns the rotary table or jig as the x is pulled through.

Almost like a ramp that forces the same amount of cam over the same amount of x travel, one for 60 and one for 90

If a rotary table is CNC controlled in addition to X travel of course there is no need to cam or link mechanically.

Thanks for posting the pic. That looks sweet!

Did you do the details on the screws, or are those purchased?
