I'm finishing a 1/2 scale Mt. howitzer barrel and need suggestions for lanyard firing. I don't want to use a fuse and want the parts removable for display. Any ideas??

A gun that small and light might be difficult to fire with a lanyard. It might not have enough mass to resist the energy of pulling a lanyard and will move when fired.

My suggestion is to touch the Howitzer off with a slow match., no parts to remove that way., no parts to put on., machine., or clean., complete control.,reliability.,and simplicity.

Is there some reason the cap could not be fired by a spring loaded device like that on a black powder pistol? Then the lanyard would only have to be pulled hard enough to release the sear, not provide the energy to fire the cap.

SD it will still move

Slowmatch in a linstock touched to a quill in the vent works just fine for me. Or if you don't care to stand quite so close, a short piece of fuse will allow you to retreat a suitable distance.

I think I've decided on a spring loaded device that screws onto the nipple.
The resistance is minimal and it can be easily removed. I'll post pictures when I'm finished machining it.
Thanks for everyones input.

bpsteve, what is the wheel diameter and approximate weight of your howitzer?

Dominick
The wheel diameter wil be 21" and the estimated weight is approx. 200-225#
