bolt extension is made (used pcb's version) will weld it on as soon as the weather clears up
and I get my argon bottle filled. I don't have anywhere under roof I can weld and I need to practice with my tig before I attempt anything permanent.

Took me 7 tries and 4 hours just to get this to post
Stupid fouled up internet :( :(

No dsl guy untill monday.Sorry fellas :( Nasty weather. I kinda borrowed my friends dial up to get this posted. how to is written pics are taken just need my dsl workin to get em posted. dial up takes FOREVER to upload a pic.

Just to get you all started

Heres what tools I have and used to make this conversion.
7x10 mini lathe with a selection of bits (I got the indexable carbide ones)
a tool steel blank bit to grind or a very small boring bar (this is to bore the wedge collar)
another blank to make a very small threading tool for the roller assembly threading
an 8x36 tap
harbor freight micro mill with a vise and milling bits (this was to machine the flat on the wedge collar/firing pin support tube) you could probably do this with a belt sander or a file
or a grinder if your careful all the flat is there for is so the ejector will clear the support assembly
a 3/16 Carbide tipped drill bit (to drill the locking wedge) carbide is a must!! anything else won't even scratch it.
A torch capable of heating steel to bright red (for hardening the pin and roller) a good hot fire would work too.

Material list

6 in section of 3/4 round steel (main support assembly)
6 in section of 1/2 round steel (rear assembly, roller assembly, lugs ect.)
at least 6 in of 5/16 round steel (firing pin)
springs (I just picked up the no 1 spring assortment by csc at tractor supply)
a can of kasenit case hardening compound (for the roller and firing pin)

that's all for now I will post the how to in a new thread in case the mod's want to sticky it.
there are a Lot of pics to help out.

Well this is a very old post still with pics. Does anyone know if the bolt was finished and if it ever worked.

A different interesting idea for sure. I bring this up for review.

Later 42rocker
