Would anyone here know if is such a tool as a 15 line per inch checkering tool. I have a request to duplicate a 90 year old set of grips, he swears that it is 15 lines per inch. I have not seen the grips, only a picture. I am sure if there is such a tool out there, someone will know about it.
Thanks in advance for any help I can receive.

The only thing I know of is the adjustable LPI ones from J&R.

Thanks for the link RC. I checked it out and the tool only adjusts from 18 up.
I was wondering if someone with a CNC outfit would be able to duplicate that kind of cut. I just know about the name CNC but know nothing of how it works other than with a computer.
Thanks again, I am still looking.
Love your signature.:D

I don't see anything coarser than 16 lpi in Brownells.

It would have to be a heckofa fine and expensive pair of grips to justify custom grinding the necessary tools. I think I'd try to negotiate him down to 16.

A one-off on a CNC mill would not be cheap, either. The spacing would not be a problem, programming in the contours would be the trick.

Jim, thanks for the post. I really wish I could hold these grips in my hand and measure the checkering. I would almost bet it is 16 LPI. If I can get the guy to send me the grips to duplicate I will post the actual LPI.
A one time set up for a CNC would be expensive as you stated.
Thanks for your input.

The grips are for a WWI Colt 1911 Made in March 1918 (15 LPI)

RHood, you sound like the guy with the gun. If so, I am glad you are reading the posts. I have been researching this for hours on the INTERNET and I can't find a tool anywhere. We will see what happens tomorrow after I make calls to several of my suppliers.
Thanks for answering the question on the gun that the grips were for.

If you can't find the tool maybe we can talk about restoring the old ones?

Thanks

Robin,
Thanks for looking at the thread.
Restoring might be an option. If you will email me some more pictures in high resolution in an attachment, so I can see what kind of shape they are in. I know I can re-cut the checkering since it is already laid out. I will check tomorrow with my suppliers and email you then.
Thanks
Carl
