MatchGuns MG2E RF part help

[conradin]

I think I'd like to see if anyone has a part here before asking for Stefano. I need a new trigger pull spring (2071 in the diagram,
"Molla per leva n.59"). If anyone has that part, please let me know.

Please move this post if you think it suits the Classified section, moderators.

You should contact your local distributor.

Or a local Spring manufacturer. Springs run mainly by diameter and wire thickness and you can buy lengths to cut your own.
Any discrepancy in hardness or tension from the original can be corrected by the adjustment screws.

MatchGuns is famously not having any agent in the USA.

I have no idea what N.59 means.

[deadeyedick]

Take a vernier ( preferably a micrometer ) and measure the wire thickness. Then measure the 0.D. of the spring, and you're in business. Contact a spring manufacturing company and give them these dimensions.
Don't concern yourself too much with Matchguns codes which may only apply for their reference.

The spring is gone. No way to measure now.

You bought the gun knowing this condradin, better now to find a solution to your problem.

It seems you have two alternatives.

1. Contact Stefano who will mail you a new spring immediately.

2. make a spring from something similar. It may be a pain but if you look closely there are billions of springs at your disposal that can be cut to length and made to fit.

After all it is only a spring to provide a return for the trigger.

2. make a spring from something similar and adjust the tension to suit. It may be a pain in the ass but if you look closely there are billions of springs at your disposal that can be cut to length and made to fit.

I have no bitterness whatsoever. It is part of life about owning a MatchGuns in the USA. I bought the very last one off the hands of Neal Stepp, thus getting a good bargain. I also know about the potential service problem, hence I have a Pardini as a backup. I am communicating with Stefano right now.

What I am asking, if anyone has one right now who has a spare spring, here in the USA, it will be great. I don't know who has bought off all the spare parts from Neal over the years.

If you have a MG2 of any sort, then please measure the spring. Someday neither Cesare nor Stefano will be available and then everyone will be on their own.

[deadeyedick]

I recently sold my MG2 RF however will take measurements within the next few days after contacting the new owner and p.m. the dimensions to you.

In the meantime why not call Neil Stepp and ask where the parts ( if any ) went.

[conradin]

Good idea...except he still has not emailed me back after a week.

Wire diameter .48 millimetres or 0.019". Free length 8.7mm or 0.3425". Outside diameter 2.82mm or 0.111". Inside diameter 0.125". Given tonight by a MG2 RF owner. Now technically you can order your own if something happens and Stefano cannot be reached.

As someone who regularly has to order springs, I would have thought that you will also need to know the material and number of coils. These can dramatically change the strength of the spring.

Of slightly less importance would be the end type (if in doubt, ground ends are the most common on compression springs).

Active coil is 8. Close and squared. I actually have the photo now. The only problem is I don't know about the material, it is black. It is the same material as the trigger spring. I was told it is not a stainless steel..but piano wire is usually silver, not black. Advice? Maybe it IS stainless steel and the owner does not know?

My understanding of the spring condradin has been referring to should make it a tension or extension spring. There is no need to know how many coils per inch as would be required with a compression spring. However I may be thinking of a different part and the electronic may use a different trigger mechanism to the manual.

I am also confident that the material is standard spring wire appropriately heat treated. As mentioned earlier the spring is only for the purpose of returning the trigger to its starting point and certainly nothing hi-tech. The tension required is adjusted by an Allen head screw to increase or decrease tension.

This spring could be replaced by a any number of modified, similar diameter extension springs within five minutes as its purpose is very basic.

If we are talking about different parts please let me know.

I must have missed something here as my understanding of the spring condradin has been referring to should be a tension or extension spring.

If that's the case then I would apologise for confusing things.

I just read your first post on this topic regarding cutting stock lengths of spring to length. That is more common on compression springs.

[conradin]

Completely different parts, in the manual it is listed as "trigger pull spring" (Molla per leva secondaria di scatto), which is different from 'trigger spring" (Molla ferma caricatore). The part that it is responsible holding is " Secondary release lever MG2 E" (Leva secondaria di scatto), which is really a sear lever. There is neither the word "sear" in the English manual, nor the equivalent in Italian.
The trigger works on the "Pawl"(Portagrilletto), then "Contact"(Contacto), then "Release lever"(Leva primaria di scatto). The solenoid sits between the release lever and the secondary release lever.

Trigger>Pawl>Contact>Release lever >>Solenoid>>secondary release lever>Hammer
So essentially it is a series of sears.

When you pull the trigger, the pawl and contact and the release lever will move in unison, meanwhile the solenoid is activated, and secondary release lever into position to mesh with the release lever. Once meshed and out of position, the hammer is released.

To set the pistol into dry fire mode, one simply pushes a pin (safety) to jam the hammer. For the athlete everything still feel the same because the entire train of sears still moves, and so does the solenoid charge. The hammer just does not drop.

It is still good to know data like the amount of active coils on this spring. The strength of the spring determines how minute an area the release lever and the secondary lever will mesh, similar to a hairspring trigger. Since this is a RFP, it may make a difference.


The trigger pull spring is to ensure the secondary lever to be pushed into a position that is ready to be mashed with the release lever when the solenoid is charged.

Thanks conradin I had a feeling we were possibly talking about different springs.

It appears you have no alternative other than to plead with Stefano for a quick despatch.

[Gort]

conradin, Your dimensions don't add up, how can the the ID plus two wire diameters be larger than the OD????
Gort.

[Rover]

Conradin doesn't add up.

Go down to your local Ace Hardware and buy a few that look like they might work. They're cheap.

Why is simple so hard for some people.
