I am looking at ways of making a shroud for a springer with a cut down barrel, so the shroud will also be a cocking aid.
I can thread the muzzle and make a threaded bush to screw on to it and slide into the outer tube. This will centre the muzzle in the tube another push fit bush (nicely shaped) should take care of the breach end of the shroud.
The shroud (Thick Walled Tube) and threaded bush are aluminium; the rear bush could be alloy or delrin. The picture is not to scale.
I’ve made up a short version as a silencer using “Red Stud Locker” to glue in the treaded bush. I would prefer not to drill through the sides of the shroud and use grub screws to hold the bush in it’s not that thick 3 to 4 mm so there would not be a lot for screws to bite into.
From past experience I know how tough Stud Locker can be but I’m concerned that it might not hold when the rifle is cocked repeatedly.
Can anybody suggest a better way of fixing the threaded bush into place? I suppose I could simply flood the area between the front bush and the back bush with epoxy resin but then I would not be able to get the shroud off.
