First custom: machining everything myself

[CaptnC]

I'm so envious!

To have those machines and the knowledge to operate them...awsome!

While my project was nothing even close to what you are doing, I did an AK receiver on a 80% blank...at least they called it an 80%. More like 45%...

Biggest difference between our project, mine was all done with hand tools...not even a drill press...hand drill and files...I used my wire feed welder to spot weld the rails in place.

Sorry for derailing your thread!

Can't wait to see how you work through this project!

All right, new update! I got quite a bit more done on the bolt. I had to make a flat bottom drill to get the shoulder about 4.5" deep that the firing pin shoulder will bottom put on. Where it's at right now I will be about .03" protrusion in the firing pin.

Also got the bolt into the mill and after a hell of a time designing the swarfed surface the the firing pin actuator rides on for the back end of the bolt... got the and the detent cut and then cut the lugs to a very close size and hand for them to the raceway! Smooth as butter!!!

At this point I also decided I will be making my own bottom metal, designed around an AICS mag. The bottom metal I was going to buy ended up being an 8-12 week wait so I may as well make my own.

This thread makes me want to go to machine school and clear out a bay in my garage so I can fit all of the machinery. Anyone want to donate tuition and equipment? So awesome!

This is cool! Are you making a flat, cone, or Remington style bolt face?

 

[livetohunt]

Just a standard Remington bolt face. I'm still trying to make sure I have the extractor and ejector places correctly for the SAUM bolt face diameter.

Let me know if you decide to go into business... I'd be more than happy to be your official product tester.

You are a very talented gentleman. You should be very proud of what you are doin. Keep us posted awesome job

If I was you I'd look into
Putting double ejectors on it. I've seen a couple bolts lately that have twin ejectors and they look well thought out. I think it helps direct the spent casing straight out the side of the action without Pushing it upwards. I've seen several people have problems with ejectors pushing the spent cause up and hitting the windage turret on todays bigger scopes. This sometimes causes the case to fall back into the action and is a real
pain.

I will roll with the single ejector for now and if I have problems make another bolt with two. After this I'm turning right around and doing a titanium receiver for a lightweight 300 WSM build maybe I will try two ejectors on that one. I want to do a titanium bolt arm.... will be interesting to see if I can weld titanium to steel and get it to hold.

Good thing laser welders are good at welding dissimilar metals.

Welding Titanium to carbon steel is not a great idea ( HORRIBLE IDEA).
If you weld titanium to titanium, TIG weld it using a trailing gas purge as well as the initial torch purge. SLOW AND CLEAN.

 

[livetohunt]

Perhaps then I'll do the lightweight build with a savage style floating bolt head out of stainless and then do a titanium bolt body and titanium bolt arm and knob.
