I'm not aware of any licensing requirements to make gun parts. It seems to be just a way to say he's not interested. Insurance requirements may require higher premiums. I know shops dealing in aircraft and aerospace parts pay higher premiums.

Yes wire EDM is slow but in most shops the process is unattended or one operator runs several machines in a cell. The process can make very precise parts. Waterjet is another way to cut out the blanks for the hammers. It is faster but not as accurate as EDM. A combination of the two may be the best way to go. Cut the blank with waterjet and then the sear notches with the wire EDM. Any way you go the hammers should be hand fitted to the rifle they will be used on for the best fit and function.   

Okay, anybody actually have one of these in their possession?  If you do, put it on your scanner, and scan me a few jpegs, rotating the hammer 90 degrees each time, and flipping it over so that we have a different perspective from the other side.   I have several standard hammers that I can measure  and compare to get the sear and other dimensions right.

With the scans, I can create a CAD file and get a bid on producing a lot of them from 4140 prehard.  If the cost isn't too outrageous, I'll finance the lot and sell them.  What I would do is leave the lug generous in size, for final fitting.  Of course, the sears would also have to be finally fit too.

Anybody have one available to scan?

Here's a similar one that I did that, and created the cad file that has the below image; ready for programming for 2 dimensional EDM or waterject production:

The safety lug is a precise fit to each action. I had to do a lot of hand fiting with Prussian blue to get it correct

I already have a CAD file that's pretty close.  Only the sear notches area needs fixing-up.

I've been bit by bit trying to reverse-engineer the entire mechanism.

Sent you an email, Dave.

Good Morning ssdave!

Where are we along path to contracting someone to make initial supply of lugged hammers? Do you have enough information to get quotes on cost and delivery times?

Thanks,
Grisen

Thanks Dave,

Your timeline is OK with me. Especially since first attempt at checking consistancy of dimensions suggests expected variability from Stevens factory.

You seem personification of "If you want to get something done, find a busy person to do it."

Happily, my early M44 has a "7oclock" extractor. Next time I have breechblock, etc. out for cleaning and inspection I will take a close look at back end of breechblock, maybe take pictures too.

My M44 has same type hammer spring as shown in diagram you posted.

Would presume that the differences between "7 oclock" vs center extractors and milled vs cast breechblocks mean that Dave will need to collect data for each. Would you agree?
