Heart Burn: Coil Spring Vs. Leaf Spring

[FishDFly]

Was wondering why the heart burn over having a coil spring (T/C and Lyman) versus a leaf spring?

Why the need to make the change? Seems kind of expensive to make a change in a rifle that you cannot see, especially considering a T/C Hawken which everyone complains about not being P/C and H/C. The change in a Lyman is not going to increase the value of it.

I assume both T/C and Lyman chose to use a coil spring because of manufacturing costs.

Lots of folks twitterpated over the coil spring inadequacy. Hammer blowback seems to be one criticism, but nipplee need to be replaced before blowback becomes a problem.

Shooting the same coil spring T/C lock 25+yrs.
Milage may vary....

Hi,
The problem is that a coil spring becomes harder the more it is compressed. A "V" spring properly made and fitted in a properly designed lock has some of the qualities of a compound bow in which there is a let up of pressure when pulling the cock from half to full. That allows a lighter trigger pull with a simple trigger. On TCs and other mass production guns with set triggers and coils springs, you don't notice it. It is not much of an issue with percussion guns but flintlocks with coil springs are just terrible to try and tune well. It is really hard to balance the springs for best sparking.

A coil spring compared to a leaf spring of the same quality is less likely to break. A well designed coil spring lock with careful construction should be the best thing since sliced bread. Unfortunately coil spring locks are made with mass production in mind. For me I shoot these old time guns for what they are so leaf springs and and all the other short comings are excepted.
