im starting the build on my new little scratch homebrew pistol. using a modified sten bolt.
got my teacher let me use some tube.
so hers my plan, in pretty much chronilogical order. and a few questions at the end i need some read good advice on
1 in a few days, anneal my bolt and carburize it in the furnace in the shop.
2 once annealed, cut a flat out to clear and old rommy ak hammer,
3 fabricate a firing pin to the specs i need, (to be determined) and drill a hole for it, in the
lathe of course.
4 once i make my pin, and mod the bolt, re heat treat and temper as needed.
5 once i am all taken care of on the bolt im gonna get that pipe, and immidiatly install a rail of key stock or tool steel rod, and weld in the top of the tube,
6 i need to then design a rear plug for the tube and a recoil system, i will use 2 steel rods to utilize springs( i make my own springs ) and make a stopper/buffer to put in place.
7 i will lathe me out a cocking handle and position it on the left of the gun. the mag well on bottom front and eject straight up
8 I could buy a mag well,,,,, lol , I think ill make my own thankyou, would you like some tea. Im working on tht right now in bed.
9 Ill be using sten mags(cuz that what i got) so im sure my famous feed ramp will be in order.
10 I guess from here, ill go ahead and mount the fcg. ill make the cuts and mesurements nessesary and im going to cut the center section of a defunct ak build reciver and weld to the bottom of the tube, or i will fab a body from 1/8 plate and a grip stick in which i may fab my own ironwood grips with a hand rub oil finish.
11 once i have this figured, ill mount the barrel supported in a single yet long trunnion from the lathe
12 now i like the mp40 sight so.... ill make my own! hehehehe hahahhah muahahaha
13 to top it off i think i will make a thread on shrowd so i can swithch between the mp40/m3 grease gun look to th tac 9 look with allthe ventalation holes. the metal will probably be flat black..
THIS IS GONNA KICK ASS!
now i have a few question,
1 What kind of material do i want to make my firing pin from? tools steel? heate treated high carbon?
2 how would one figure how much spring you need to cycle right or at least close? i thought mabey one longer and lighter then a real heavy one at the 1/2 way point.
3 idea on how to close up the rear and not be permanant so the gun can be dissasymbled.
i thought a nice round ended plug with a large pin and a reienforcment block on the out side. but needs to be strong unless i can stop the bolt from inpacting anything hard. like using a secone heavy spring
any ideas yall have please feel free, id love to incorperated someones ideas to better the design, budget/ability willing.
i need quick help on the pin thought, i have a narrow window for time to use the heat treater because the teacher only uses it 2 a semester, and tha s it
thanks all MIKE
