winchester 37A 20ga disassembly

I broke my nephew's winchester 31A 20ga shorgun trigger. How in the world would I disassemble it and change or make another the trigger and fix it ?

singleshots can be a buggar to assemble requiring you to make some "dummy" assembly pins to put them together. They are definitely a learning experience the first time. The pins holding the parts together need to be driven out from left to right with you facing the rear of the gun.

The trigger & its hairpin spring is held in place with a pin through the lower tang. The stock must be removed to drift the pin out.

Let me get this wright. I just have to drive the trigger spring pin out once the stock is off ?

[Cap'n Morgan]

That's about the sum of it... the trigger will practically fall out, once the pin is gone.

[danyboy]

Thanks a lot for the info. I'll try that.

Capt'n Morgan,
Tried removing the stock in vain. I disassembled guns before but I just don't see it with this one. How do you get the stock off ?

Finally,
I managed to remove the broken trigger. Now the other challenge: get a new one. Obama restricted the sale of gun parts to Canada. I have to find an american retailer who will accept to ship me one.

I made a new trigger for my 37 12 gauge it took about a half hour.

[danyboy]

Half an hour ? What kind of material did you use ? I was thinking of using stainless cause I work with stainless all the time ( steamfitter working with a tig welder ). I am away from work for the holidays. I tried to 'J-B-Weld' it in the mean time and it seems to hold. It is made of a mix of metal and don't think it could have withstood the heat.

[Cap'n Morgan]

You'll need to make the trigger from a steel that can be hardened, or the sear will wear off in no time. If you can't find any suitable steel, a small piece from a hack saw blade can be soldered to the tip of the trigger.

[gunguychuck]

You can use hot or cold rolled steel available in most hardware stores and use kasenite to case harden the sear part.
