I got a used springer that someone converted to fire .41 balls?, paintball maybe?. I want to line the barrel with a .22 so its useable again. Need OD of a Crosman 7/16 barrel turned down to about 10.4 mm, a tiny bit less so its not a press fit. Would be about 18.5 inches long. It needs to fit inside a .410 barrel.
Is the rifle such a rarity that purchasing a completely new barrel for it is not possible, or completely uneconomical?
My question would also be- if a barrel can be machined to 10.4mm - how would you retain it in the reamed-out larger barrel? Glue, solder, some sort of press fit, collar and threaded end?
JB weld would hold it.
Acraglas is what is normally used to hold barrel liners in PB work. So I would think that a good two part of thin consistency would work very well in an AG as would Loctite shaft and sleeve retainer
A factory barrel is kind of a pain as its only sold with the compression tube as well. Since the crosman barrels are dirt cheep (thanks Eric) I figured this would be the best way to go. I also dont know if the breach was opened up at all for the larger bore. I figure I will use epoxy and set screws to retain it.
