There was a string in art of the rifle that dealt with this about ten days back...It confused me a bit..so i've posted this message here and on an engineering post...can anyone help.
"Okay heres the dilema ...two pieces of pipe
one is a gun barrel..the other a compensator that goes over the end of the
barrel
Usually the compensator(female) is threaded ,as is the end of the
barrel(male), they screw together like a bolt(barrel) and nut (compensator)
My question is...lacking threading..or pinning the compensator in
place...can the compensator be machined to a close tolerance, heated, then
slipped over the barrel , and cooled to a room temp,to hold in place?
I was under the impression that expansion would be inward as well as
outward, I realize I hadnt mentioned expansion along the outer circumference
because that wouldn't be a concern in the actual fitting of the peice.
I assumed the compensator...with it's inner diameter being slightly smaller
at the start, than the barrel outer diameter, could not, by the application
of heat, be made fit ..because the heat would further reduce the inner
diameter of the compensator.
Someone mentioned to me how bushings are applied to solid rod with heat
then cooled to a snug fit...how can this occur?
Can it occur at all...What is physically happening when the bushing is
heated that allows it to slip over a solid rod"
