I was sent a Farley Action that had the lugs shear off of the bolt body.

Jackie - What would that bolt cost if you included all of the time you've worked on it [researching, designing, building] overhead costs, the materials and a 50% profit margin [or, whatever profit margin would be appropriate]?

You sure couldn’t make a living doing stuff like this.

I have a lot of resources at my disposal, Since my business buys a lot of steel, I can pick up the phone and ask one of the suppliers t get me a piece of Premium Aircraft Quality 4340. I can call, a local Heat Treater and get the heat treating done. The end mills and drills are just a call away as well.

My time is the intangible. As a machinist, I figure out how to perform the operations with the tools at my disposal. But since I have never built an entire bolt head, I did have to spend a certain amount of time simply thinking about it.

Thinking about these things are what keeps a brain health and happy
 
I have complete confidence in my work and I would feel the same way about Jackie's but my worries now would be the metal I can come up with I don't have much trust in anyone of the suppliers any more .
I'm just digging a hole
 
It’s pretty much finished. I attached the bolt head to the original Farley body, then mounted the bolt handle. I used a 10-32 socket head cap screw and e 8-40 screw.

everything is timed correctly, except I missed one length. It mounted a trigger and it only has about .120 firing pin fall. That means I will have To ffset bush the trigger hanger to get the .230 I want.

The bolt head and bolt body are locked together with two 5/16 steel dowels that are pressed into reamed holes. It as difficult to make it look as neat as I wanted due to the bolt body fluting, but it is rock solid.

This is all looking pretty good. IMG_2775.jpegIMG_2776.jpegIMG_2777.jpeg

At my shop, we have concerns with material. That is why we stick with reputable manufacturers. We even try to deal with the same sales representative because they know our requirements and needs.

Several years ago, we were offered around 20 bars of 9” bar stock that averaged 30 feet in length. It was offered by a broker who knew we used a lot of 1018 in this size range..

His asking price was ridiculously cheap, around 25 cents a pound. He said the steel came out of one of the old Soviet Block Countries, he acquired it through an international auction.

We told him we would take it if he would furnish a sample to have tested. He agreed, as he really did not know the chemical make up.

It turns out the bars were an alloy similiar to 8620, which was not suitable for our needs. I suspect that it came out of an old communist munitions factory, who use alloys like this because of their superior case hardening properties.

It would have been a great purchase.

That's good
I probably could find something. A trusted supplier through my employer at this time.
I'm going to need to
 
I machined a new shroud from the Graphite Impregnated Delhren, that‘s what I use on my other Farley’s. The final thing will be to redrill and tap tap the scope mount holes fron 6/32 to 8/40. I have a set of Bat direct Mount rings that I will machine the bottoms flat to mount atop the Farley, as the hole centers are the same.image.jpgimage.jpg

Quite the mental challenge, figuring out how to affect each step. Machine work is easy. Figuring out HOW to do it is the hard part.Guessing Jackie likes a challenge.
That's probably the biggest real difference between a machinist and a machine operator. Lots of machine operators out there but not many to figure out the setups to make it happen. A lot of which comes with experience as well as a good noggin.
