Mechanical Advantage

[Jason_Adams]

Good morning!

Has anyone done or know of any studies on the mechanical requirements of each lever action rifle platform? Some useful measurements would include the following:

1. Mechanical advantages/disadvantages of each platform tested.

2. Distance of travel for each lever with factory or aftermarket standard modifications.

3. Measuring the necessary force for forward and rearward travel of the lever.

 

Thank you,

Re.#2

The minimum allowed lever travel distance (i.e. "short stroke" modification) can be found on pp.36-37 of the SHB.

Hello there!

It certainly does. That would help with understanding some of the limitations that we would need to figure into the equation in the second portion of the second bullet point. I'm hoping that someone has performed an in-depth analysis on each lever action or can point us to a granular study of the mechanics for each bullet point. One interesting additional point I didn't think to mention above would be the various steels and mixtures used by different manufacturers to determine how much flex or lack thereof occurs when working each lever.

I feel the knowledge you desire will remain unrequited.  OR:  Who Cares??

I’m not sure that anyone has ever been interested enough to compile the measurements and specifications that you are referring to.

 

You MIGHT try contacting the individual manufacturers to see if their engineering departments or teams have recorded the measurements and the metallurgical data.

 

Given that the many gunsmiths and aftermarket manufacturers all use different methods and materials and that in some instances, they stray far from the original designs and specifications employed by said manufacturers, you’d be taking on a monumental task to gather and collate all of that information.

You could ask Jim Bowie....He seems to have been in the middle of all this...Way back when it started.....

I know that Shotgun Boogie has done some computer modeling of the Uberti action.

Fantastic! Thank you very much for the information!

Thanks you very much. Good idea regarding reaching out to the manufacturers.
