Hammer Spring Replaced With a WIN 92 Spring
Hammer Spring Replaced With a WIN 92 Spring
Searched to see if there was a thread. Maybe this will help someone.
A friend borrowed my 44MAG 92 for a shoot, and the hammer spring broke. Being a good guy, he found a replacement for it, which was great, except for the fact that whoever provided it furnished him with a Miroku Winchester 92 spring, according to the packing slip.
So, an experiment had to follow. Roughly figured the spring tension length (the WIN is shorter, and wound wider) and milled an adapter from bar stock. Shouldered it to fit the spring, and installed the adapter against the hammer.
This is the smoothest this rifle has ever run. It has a previous action job and trigger/hammer mating, but has NEVER been this slick. Pleasant surprise.
Anyone seen this before? Should it have affected the rifle so much?

This is the first report I've read of using the Winchester part. Pictures, please!

Re: Hammer Spring Replaced With a WIN 92 Spring
I'm confused - what do you mean "milled an adapter"? Why would you need an adapter? Aren't you replacing a Rossi 92 hammer spring with a Winchester 92 hammer spring? Is there that much difference between them?
Re: Hammer Spring Replaced With a WIN 92 Spring
Pix are in my IMGUR. IF this doesn't work, patience please, I don't post a lot of pics, and may have botched it.
First pic shows the installed piece.
Second shows the pieces used to guesstimate spring adapter length.
Third is the shoulder, however, this is not the correct center hole size. Broke my 10 wire bit this AM trying to recreate for illustrative purposes, just grabbed the first one in the index my finger hit.
In short, used a piece of standard 3/8 round bar stock. Milled a 10 wire (.193) center hole, and a shoulder at .210 diameter, .0312 depth. Cut to .55 or so, mill cut end flat to final length of .5, not adding raised spring "guide" (or you could cut to .5312 end to end). Blued with a quick coat of Oxpho from Brownells.

Ah, I see now, thanks! Adapter/spacer made on a lathe, hmm? The "milled" comment had me cornfused.
Re: Hammer Spring Replaced With a WIN 92 Spring
Sorry for that, yes it was cut on the lathe, but we've gotten in the habit of saying mill, as it's an all in one machine.
