Reversed Main spring

[Tanners Owner]

@Protocall_Design does your mainspring bend mod reduce the lifespan of the mainspring?

Am intrigued by your bend, so simple a concept- thanks for sharing. Might give it a try, but need to find the replacement mainspring screws first

I think there's room for everyone - Those who stick to what they know, and those who like to try new things.

There is nothing dangerous here, like going to the bottom of the ocean in a submarine. This is one of those things that can't hurt, might help. No harm in giving it a try. Anyone who wants to, can try it, anyone who doesn't want to, doesn't have to.

I do feel sad for those who go through life afraid to try anything new or different, though. Life is what you make it. I'm making mine a fun adventure.

Thank you for your contributions to this thread and reasonable approach. Do I want to try this bending approach on my next range revolver? You betcha!

I have guns that have had this configuration in them for over 30 years and haven't worn one out yet. I think they probably have the same life as a regular one, but don't know yet. There are some springs marked with an S for stainless. Those never did work right, so don't use them for anything.

The main thing is to make the bends with a large, smooth radius. The best way to do this is to bend them in a vise or arbor press with a V block or 2 rolls on the bottom, and a 1-1/2" diameter roll on the top. The spring lays across the gap on the bottom, and the top roll bends it down into the gap. You have to fine tune the shape a bit by trial and error, but when you get it looking like the pictures, it should work.

I will say again, as always - These type of mods are for range guns only. I shoot a lot of matches and competitions, so I want the best DA trigger I can get, for the best score on paper and steel.

DO NOT do this for a carry or duty gun. Keep THOSE factory stock. Yes, I can shoot a 12 lb. DA gun quite well enough to get the job done. You can too, with practice.

Not sure who you think you’re kidding but reshaping mainsprings has been done by lots of top end revolver smiths. I learned from Ronnie Power but Jimmy Clark and many more including Pachmayr reworked mainsprings. Here are some I did when I was in the business years ago. The two on the left and notice they’ve been polished to remove those pits and roughness along the edges. No place for stress risers they have to be removed for a first class job. I posted this info and photos years ago here.

I'm not kidding anyone. I said in the original post that I haven't seen this anywhere else and didn't know if anyone else had done it or not. I wasn't here years ago, so I didn't see that post.

For something original that I know hasn't been done, check out my patent pending drop in hammer kit at Welcome to RevUp Action®! - RevUp Action®. Just changing the hammer makes the trigger pull get lighter and lighter down around single action pull weight by the end. I invented and make the hammers, and invented and built the trigger pull gage to show what it does.

For those who are trying to portray me as a kitchen table hack, I have built and shot custom S&W revos for over 40 years, been a tool & die maker for over 45 years, have many patents in various fields, and have a complete machine shop that I earn a living from on a daily basis.

Ah come on man let’s be honest here okay. On 6-14-2020 I posted in a thread called “ Main Spring Questions “ where I discussed this topic and posted the same photo of four springs above. You then posted a reply right after mine and made several others in this thread ? Your posts almost seemed like you had a much different opinion on shaping main springs. In fact you said you’d been using them for over “ thirty years “ ?

 

[Protocall_Design]

I didn't recall that thread. If you do the math, I could hardly have copied your work from a thread 3 years ago, 30 years ago. At the time I came up with it, I didn't know of other ones.

I apologize if I have offended you in some way. I don't think there is a need to call me a liar. If we have a misunderstanding, let's work it out.

I have always tried to help and support everyone else on here. No one is perfect. Sorry you feel you have to tear others down.

I’m sorry if you think I’m calling you a liar as that was not my intent. What I’m saying is if anybody wants to go back to June 2020 to the thread titled ” Main Spring Questions” and reads your comments it’s clear there are quite a few contradictions about reworking main springs. And you did indeed see my earlier post as you replied to it. It should also be noted that shaping these springs is not my idea as I point out. So if you’ve changed your mind it’s your prerogative. However good luck trying to patent something that has probably been done many times over the years

Regards

You are way off base here. In the photo you posted spring shapes do not look anything like the one posted by Protocall_Design.

No where in any post in this thread our yours does he claim to have invented reshaping mainspring - he does take the time to explain why the shape he uses works. Many smith in the past have reshaped spring but I have never seen any of them claim they invented anything.

He never said he was patenting spring manipulation or bent springs. I would suggest you read the post out load and you will find your reading into what has been said.
