CNC Machining & Small Runs of Specific Items

It seems that with the proliferation of CNC machines in smaller shops and even a few individuals, it might be possible to reproduce items such as Kenyon triggers rather easily. Once the specifications and prints were established the rest should be easy. Now wouldn't it be nice to be able to get a marvelous trigger that could be carefully fitted to achieve superior results without breaking several banks?

I have heard that Mr. Kenyon hand filed every trigger and fitted it to a specific rifle. Such fit could not be achieved by machining alone, but it could give a darned good starting point for exact fit.

There are supposed to be a few Martini International Kenyons floating about. What is one of them worth?

May be totally off base, not the first time and I hope it is not the last either.

Just the musings of a futile (not fertile) mind!

they call those type shops prototype shops. they do one off and small runs and are specialists in machine changeovers to minimize your bill at the end. now, if you had a kenyan trigger for a martini would you be the only interested party in purchasing one? I'd say yes. so a prototype shop may be just who you need to help make your dream a reality. they dont charge much in the grand scheme of things but I'd suspect on the many intricate parts and hardnesses required you'd have $5000 in this trigger.

One of the most common misconceptions I hear from people not is the business is something to the effect of..... "So, you just stick the blueprint in that machine and it makes the part, right?" I can't tell you how many people I turn away in a year that come into the shop with a broken lawnmower part thinking I've got a bunch of automated parts replicators that dispense replacements like a Coke machine. I usually tell them if the part can be bought anywhere on the planet it'll be cheaper than I can make it for. Parts in quantity is a different story.

If you mean fits that are full of error but do function in a case by case assembly, then you are correct.

I get a huge kick out of the Les Baer commercials on TV touting their hand fit jobs and "tolerances that no CNC can hold". L-O-friggin-L! I can just see the quality guys coming in from the Lockheed type companies with a critical aerospace part and me telling them..... "Well this here is a pretty tight tolerance part where peoples lives might be on the line so I'm gonna have to go fetch my Dremel and gunsmithing files for this one". Hehehe.

I like stories if you have the time to tell some.
