Anyone know what a mainspring tester looks like?

Hey folks,

I would be interested in finding-out what a mainspring tester looks like.

A while back I made a recoil spring tester...but I would like to see if I can concoct a mainspring tester.

I would also need to have the compression measurements.

Any links, or pictures, would be appreciated.

Thanks.

Really?

No one?

No one knows who sells one, or no one owns a mainspring tester?

Any info on compression rates if I were to make one?

Hmmm...

To get a basic idea of the weight of a Mainspring, I put it in a Mainspring Housing and then use a bathroom scale and press down on the Mainspring Cap so the Mainspring compresses about 3/8". Read out the weight on the scale.

I've never heard or seen one for sale. Shouldn't be too hard to fab one or too hard to come up with the compression distance. Pop the beavertail out and measure the travel of the strut.

CYa,

Below are photos of my version. This was originally built to test Glock striker springs but works for 1911 mainsprings also. In use I place a scale on the table of my drill press. The aluminum base with the guide rod is placed on the platform of the scale. The spring slides over the guide rod with the brass follower on top. I set the stop of the drill press to compress the spring at the correct length for the spring application I am testing. Read the spring weight off the scale.
