Has anyone had a play with making up rubber wipes for their modular suppressors?
something similar to welrod pistol rubber baffels
seems like it would be piss easy to make a circular piece of rubber that would fit between baffles that you just replace on the regular by taking it apart
im curious to know the effect on accuraccy, as it should have an effect as the bullet literally touches the baffle
rubber or leather? Sounds like a question from a fetish forum I know,
but I thought some of the ww2 designs used greased leather washers.
I was thinking rubber like inner tube as not to mess with the bullet too badly by being overly thick
Easy availabile ect, like the members of this forum you speak of
I did a quick google on it. The wipes don't last that long and affect accuracy pretty badly. Good on an assassins pistol at close range for a couple of shots but otherwise not so good.
The Welrod was designed to be fired in contact with the target for maximum effect so accuracy was of no consequence! If you want hit things further than 25 metres then forget about wipes. Wipes are pretty much fully degraded after 10 shots anyway.
I made a wipes can once, was amazing at sound for the first couple of shots but I couldent even hit a coke can at 10m with it
Check out this for modern suppressor with a wipe.

Skip to about 15min in for a 300blk with wipes. Pretty impressive! Cant imagine accuracy is too flash though.
from that video Im sold
I am hoping to do something similar with a wipe at the end of the can with a hole the size of the bullet
im thinking the air that the bullet is pushing will open the hole enough to avoid bullet contact so not really a wipe
but then it sort of closes behind the bullet
anyway 10 shots once my rifle is sighted in is far more than id use on a typical day hunting
If I use five its either been a really good hunt or somethings gone wrong
I have seen in suppressors that bullets dont even need to contact baffles before accuracy is affected
I am dubious about what effect there will be accuracy wise and the sound difference with and without wipes isnt enough to justify destroying accuracy
Quick way to test if it's worth it. Try a piece of leather over the end of your can, attach with hose clip.Quote:

If you need something extra silent, get a bigger can. Less bang for your buck that way...
If you need it that quiet you are probable poaching
Perhaps not poaching but potentially shooting where one is not supposed to? (EG rabbit control in an area which is too built up for shooting but still you r own property....) Either way, sounds like someone is up to mischief....Quote:

Anyway, suppressed 22 subsonics for rabbits. No one would even know you were there if you don't do anything stupid.
Yeah or you found a cool idea from the past and you want find out more about it
Anyone who’s played with large subsonic calibesr knows it’s hard to knock the noise off a 45cal
The difference in noise between a 30 and 45 cal sub is quite a lot
Just do it and tell us what it did to accuracy. Maybe at equal velocity a heavy .45 cal bullet is not as readily knocked off course by a wipe as a .30 cal one might be. But a .45 cal would make a very telltale thump on hitting anything, so is the wipe worth it unless you're planning to miss?Quote:

Getting super tight suppression for those vital few shots, it's obviously got some application... with an accuracy drawback. Another thought is that silicone wipes may last longer than traditional rubber ones.
look what I found when trolling the internet
sionics suppressor for a mac 11-9. synthetic wipes in there.
Sionics M11-9 Suppressor - SilencerTalk
This image is from your link. Looks like several handfuls of car bulkhead grommets, ???from the first stage of the suppressor??? Weird.Quote:

Or, keen to have a play! Id like to make a delisle type thing one day when my workshop is set up and I get some time.... Would be fun!Quote:

Yes, those Sionics suppressors used hollow rivets as an absorbsion system. I don't know that it was any better than anything else on the market. Pistol calibres with their slow heavy compact bullets perform best through wipes. Pre-perforated wipes work best, and neoprene is slightly superior to rubber or leather, but all of them still degrade very quickly (10-15 rounds max). That is perfectly acceptable for covert military use.
[QUOTE=gundoc;775631]@gundoc, have you any advice for someone wanting to give this a try? Iv got a Schultz and Larsen Thunderdome for my .45Quote:

Cheers.
[QUOTE=40mm;775633]Oiled leather works quite well. The wipe needs to be supported on either side by washers, the rear washer needs a hole at least 1mm over bore size, and the front washer needs to be about 8mm over bore size to give the wipe room to open cleanly (assuming 3-4 mm thick wipe). Put a cross slit in the wipe at least 1.5 times bore size, and a 3mm hole punched in the centre. Two wipes work best, one at the front of the suppressor and another inside closer to the muzzle (but still at least 30mm away to avoid too much burning).Quote:

Can see the rationality about a lot of complex shaped rubber inside the silencer - after all rubber absorbs a lot of sound energy, converting it into heat - in addition to its absorbing some heat of the blast but metal probably is better for that.
Some silicone rubber is very heat resistant and would make up some nice filler, definitely going to use something like that in my current de Lisle like project.
I have a shot out SMLE that will be dedicated to lead boolits with a 15" barrel. I need to take off exactly 9" of the 24" whippy barrel to allow me to put a 16M2 thread on it, 16mm being the barrel diameter at 9 inches from the business end. The suppressor won't index on the thread so I can thread it with a hand tool. Shame for the rifle as all matching numbers etc, but shot out is shot out.
