harpoonlouis Posted September 15, 2013 Report Share Posted September 15, 2013 Just picked up a cheap hushpower 410 and want to know how they are constructed. Can I dismantle the full length silencer can, is it threaded or welded. Anyone who has already done this care to let me know before I try and get it wrong Thanks Quote Link to comment Share on other sites More sharing options...
kennett Posted September 15, 2013 Report Share Posted September 15, 2013 If its on a Baikal mine had a threaded collar welded near the forend and the moderator screwed on to that Quote Link to comment Share on other sites More sharing options...
harpoonlouis Posted September 15, 2013 Author Report Share Posted September 15, 2013 Its on a Peddretti and doesn't feel like a thread but I haven't applied any kind of force to find out yet Quote Link to comment Share on other sites More sharing options...
kennett Posted September 15, 2013 Report Share Posted September 15, 2013 sorry can't help there! Is there a grub screw or anything? I wouldn't worry too much about getting inside, the hushpower one was a just a tube with a ported barrel and worked better with a bit of crud in it Quote Link to comment Share on other sites More sharing options...
sitsinhedges Posted September 15, 2013 Report Share Posted September 15, 2013 If it's a Pedretti single barrel it is threaded on to a bush at the breech end which should unscrew with some effort. The aluminium threads can seize quite easily making removal awkward. It will also have a steel centering collar welded to the muzzle of the barrel which acts as a stop for the baffles that are forward of the barrel. The centering collar will drag all the accumulated **** back with it as you slide the outer tube off. Once you clean it put some copper-ease on the threads to stop them seizing again and grease the barrel outer to stop it rusting unnoticed out of sight.

harpoonlouis Posted September 15, 2013 Author Report Share Posted September 15, 2013 OK looks like I will Kroil it for a couple of days then try to get it off. Has a lot of crud free floating inside it which I would like to get out. Thanks all Quote Link to comment Share on other sites More sharing options...

harpoonlouis Posted September 16, 2013 Author Report Share Posted September 16, 2013 Same symptoms here. Usable but I would prefer to clear out the crud inside if possible. Quote Link to comment Share on other sites More sharing options...
harpoonlouis Posted September 16, 2013 Author Report Share Posted September 16, 2013 Anyone ever added additional sound absorbing material between the baffles, like scotchbrite? Quote Link to comment Share on other sites More sharing options...
sitsinhedges Posted September 16, 2013 Report Share Posted September 16, 2013 Anyone ever added additional sound absorbing material between the baffles, like scotchbrite? Don't waste your time you wont notice any difference. For those who loosen the outer tube but can't remove it you need to be using that collar that is welded to the end of the barrel like a slide hammer, gently, drawing all the **** inside the tube backwards until it is off. Bear in mind that it is a corrosion trap and wants inspecting every once in a while. I've had quite a few Hushpowers various and I've never had an issue with noise increasing from cleaning a gun in fact giving the barrel outside a good coating of protective grease may help to deaden sound as well as keep any rust at bay.

stubby Posted September 16, 2013 Report Share Posted September 16, 2013 Sounds like you've got the old style 20g over/under. A single shot Pedretti type tube can be pulled off and leave all the baffle plates in place, IIRC. nope, they were both single shot, Quote Link to comment Share on other sites More sharing options...
sitsinhedges Posted September 16, 2013 Report Share Posted September 16, 2013 nope, they were both single shot, So why couldn't you unscrew it from the breech end and remove the tube with the baffles still in it? The old type O/U were a real pain because the baffles which had two holes in obviously slid down onto a pair of rods to make up a cassette which fixed to the barrel end. They did have to be stripped one by one before you could take the tube off at the breech because you couldn't spin them like you can a single barrel.

pstenson123 Posted September 16, 2013 Report Share Posted September 16, 2013 I can only unscrew mine from the breech end & only pull it about an inch away then it feels like something else is holding it on!!!! Quote Link to comment Share on other sites More sharing options...

harpoonlouis Posted September 17, 2013 Author Report Share Posted September 17, 2013 Update Threads at breech end Barrel length v moderator length Baffles at muzzle end which I haven't taken out as too tight Barrel ports time 10 The loose stuff from the moderator was from the outside of the barrel but had been shaken or shocked off and was loose this is the fine stuff from the inside wall of the outer moderator which wasn't enough to make the outside hard to remove, it was small dents in the wall that made it tight. There are no baffles or absorber in the whole section behind the fixed gas tight end of the barrel and about 5 or 6 vane baffles beyond the ported barrel to break down the exiting gases. Going to try muffling that main section or sleeving the outside with a neoprene sleeve to cut down the noise coming from the main can of the moderator.
