Cutter,


 Are you going to have a section of the cocking mechanism move able to disengage the firing pins like the RG-G or a fire only? Your Delrin cocking mechanism turned out nice.

Bruski,

Yes, I’ve decided to make a cocking switch with safety.

I’m liking this model.

I might just finish the model then start the real deal all over.

It’s only a hobby

I made the side rails from 1/4 X 1 aluminum

I had laying around for awhile. I also have

some 1” diameter aluminum tube for the phony barrels,

but only 13.375 long. That’s all the tubing.

Press in an insert with the chamber detailed.

 

I’m modifying the drawing for any changes as I go.

Should have a good drawing at the end

A  window in the front cam is needed

to clearly see the cocking mechanism

I just ordered a piece of 3” diameter

Aluminum , decided to make an aluminum pan.

I’ll save the brass for the real deal, besides being

heavy it looks out of place on the model.

I wondered about that, especially after you pinned two pieces of stock to make the pan, using what you had around.    Looks great !


 


What are you planning for a set of bolts?

I cut the tubes to length today and found

a piece of 4” diameter X 5/8 I can use for

the barrel plate. I might just press them in,

not sure yet. I’ll get the inserts in the barrels first.

 

That\'s all for today Bruski, it\'s warming up.

Well, I assembled the bolts after heat treatment and installed them in the carrier and have been cranking and cranking the handle for a while now. Everything seems to be smoothing out ok and I can hear the firing pins snapping although two of them sound different than the others. I wonder what is up with that now because they were all created equally the same. I will look into that later I think. I have six 38 special snap cap dummy rounds that I cycled through it with good extractions so far. I do have the slots under the bolts cut, but no pins drilled and pressed in the pan for ejection yet. The dummy rounds seem to fit the chambers a little bit looser than an empty resized brass does. I pressed in primers in six rounds with no powder or bullets and hand placed them in each chamber to test the firing pins which all fired ok. Even the two firing pins that sounded different worked, that is a mystery still. When I say different sounding, I mean they sound like they are very weak springs or something but they are the same as I checked them several times now. The dents in the primers are all the same depth which is the amount that they protrude from the bolt face. I know that I could mix and match the firing pins with the others to narrow it down some but if it ain\'t broke don\'t fix it right.

I put the slot in the bolt bottom for the ejector pin also.    I figure is not going to hurt anything having the pin ejection system in place.  IF the rounds eject before that fine.

I have some rotation, but that’s all for awhile.

I’m making my annual trip to the Pacific Northwest,

Oregon/Washington

Cutter,


 Have a nice vacation and don\'t forget to bring your laptop with you so you can design a nice hopper feed mechanism for the 357\'s.

Have a nice enjoyable trip Cutter.       The break will give me a chance to catch up a bit with the 357 project.     It goes a LOT slower when you don\'t know what the hell you are doing   LOL

Cutter- where are you heading in Washington? I\'m in the Tacoma area. If you\'re going to be around let me know!


Have fun.

Hello RumRunr, I will be in the Tacoma area in about 3 weeks.


Having lived there 50 years (13 years ago), the wife and I have grand kids to visit


in Milton.


In addition to attending my Clover Park class of \'68 50th year High school reunion, we will


visit the Puyallup Fair at least once.


This year will be hectic, so we won\'t be shopping at the Starlite swap meet very many times,


unlike our other yearly visits. 


Later.


- Ted
