Flame cutting of frames.

Curiosity killing me. Flame cutting of the frames of revolvers at the cylinder gap seems to occur regularly.
Yet revolver mfrs. seem to try for ever tighter and tighter cylinder gaps.
Since gas cools as it expands, wouldn't it make sense to slightly bevel the top of the barrel extension and turn the face of the cylinder down a bit just above where it meets the forcing cone?
That would leave a tight gap at the junction, but it would flare slightly as it neared the frame. Seems that cooler gas would be less likely to cut the top strap.
???????????
 
Lavan...sounds good. Might have to do major change in many tho cause the end of the bbl at the forcing cone is pretty thin already on a lot of em. Some folks put a piece of stainless razor blade on the top strap where the gasses impinge. A lot of folks leave the residue in place to take the brunt of the flames. And some folks just don't worry about it.

Sam....I love the smell of Unique in the mornin.
 
You can do what a number of old timers used to do, coat the top strap with graphite. The hot unburnt powder particles and gasses seem to slip off the graphite without the cutting.

Flame cutting add "character" to the gun. ;)

Good, I will stop worrying and keep on loading the Heli-arc propellant that I use in my 38 S&W Police Positive silhouette gun.

It is actually handy as I now use it as a camp stove by holding the coffee pot over the place where the gas squirts out. We have a noisy camp at mealtime as you gotta keep firing to heat the food.

:D
