ok to use a neoprene sheet?

i actually have a 1/4" chisel (for the x making) and a 24mm punch.  It's less than 1" but close enough.  I might have a 25mm punch somewhere too.

bump as this is good info

I found some great punches for wipes. Most leather and gasket punches are poor quality steel, not hardened, and not very sharp. I picked up one of these and its awesome. Tip is induction hardened and very sharp. I cut 70 duro 1/8” silicone sheet by just twisting the punch a bit side to side for a few seconds and it cut very clean.

Interesting.  I have other Osborne punches, but they take a few wacks with a 6 pound dead blow hammer on 1/8" material.  I guess I will give one of this style a try.  Thanks.

Thanks for the heads up. I have the one from Mcmaster and haven't been impressed with it. Not a clean cut and takes quite a few blows.

This is what I use to replace wipes on my cans. It’s not the fiber reinforced stuff that EA uses but works well enough for ghost, wolfman, and Vox. The punch set is a cheap chinese one but it’s got a ton of sizes and cutting silicone isn’t a challenge for it. The wipes I make with this material last a hell of a lot longer than the Deadair supplied ones.

Thx @fr3d

I use this same material on my DA Ghost and Thompson WASP.  I’ve got a couple Osborn Chinese punches from Amazon and they work well.  I don’t bother punching a center hole.  The first round pops one for me.

You are a brave man.......

Is it time to reconsider this thread being a never going to archive post instead of a pinned to the top post?  

-The OP is Hansohn Brothers (a longtime, active and very respected poster/site sponsor)
-OP updates the OP
-Great info
-People keep referring others back to this post
-It has gotten to only page 2, but is probably viewed more than any other broad technical post
-Thread is manufacturer neutral

IMO, this thread is data rich and should be pinned.

Well, so far I’ve had zero issues.........

Bump to the top. This was a gold mine I had found on google of all places. Pin this up

I don't think I have seen any posts about the wipe's durability.   How many rounds are you getting for the factory wipes and the make do wipes of the home depot washer types?

Agreed with your first part.

I get about 15 rounds thru my Aurora II before it starts getting noisy.  Twenty max.  Glock host (mostly)and AGUILA SUBSONIC 147 GRAIN FMJFP rounds.  Most all of the eight wipes are pretty shot through at that point.

I remake them from a similar to factory spec durometer urethane sheet, with the same "X" cuts, so I can't attest to the "home depot washer type" products.

Is it really that hard to save the thread to your favorites on your computer and bring it up any time without having to search this forum.

Someone had told me that these would work for the ghost and possibly the wolfman.

can you shoot hollow points through a wipe?

All the manufacturers I’ve seen say no. You don’t want an expanding round doing it’s job inside your suppressor once it hits the first wipe.

I have a Wolfman, Wipe is in the endcap.

Nope

[EDIT]  Well you can, if you choose to do so.  But if your entire rig goes flying down range, you might want to consider refraining from such activity.

You may be OK there but let’s ask the man @mageever

The Ghost Wolfman wipe is 1" diameter and the wipe retainer has a large clamping surface area so it's not necessary to be exact.  I've cut a ton of wipes out of sheet just using scissors and making them octagonal (-ish).  Just get it to fit in and it'll be fine when you tighten it down.  I designed the wipe cap around a 1" faucet washer that you can pick up at the hardware store.  I don't have the part number in front of me, but I think it's in the user manual.

A word on the central hole in Ghost wipe (or the off-the-shelf faucet washer).  If you have exactly the right diameter of wipe, it will place that center hole exactly on the bore line.  The benefit of this is that it minimizes any point of impact change and also a precision change in your grouping when using the wipe.  A solid piece can cause more accuracy and precision change.

Hollow points do just fine with a central alignment hole.

@HansohnBrothers  The wipe durometer we use is 70A for both Ghost and Wolfman.  

Other wipe material bits of info:

-Silicone is very temperature resistant, BUT it's not a tough material and erodes quickly.
-Urethane is very tough, but not temperature resistant.  Net result is it erodes quickly.
-Neoprene is the best all around material.  I found it to be the best blend for toughness as it gets hot and bullets are trying to tear it apart.  
-EPDM lost out to Neoprene on toughness, but handled heat a bit better.  Same for Buna.  They still worked well for me, though.

On Durometer:
70A is more rigid.  It will give you a better sound result, but will wear a little faster.  
60A is more flexible.  It'll last longer but flexes enough that performance isn't always as good.  Bore opening won't open as quickly as 70A, but because it flexes more, it's usually a little louder because gases can push through it so easily.

Remember that durometer ratings of a material are very much an average.  The 60A stuff we first purchased for Ghost production actually fell in the 70A range.  There can be a 10A-20A range in material you buy from Grainger or McMaster.  70A seems more consistent. If you source directly from a manufacturer then quality greatly improves.  

These are general points that I found as I've jumped into development on products and had a window to do some testing.  I don't actually shoot with wipes much so I'm sure some of you have probably found certain usage conditions that probably don't fit the info I've dropped here, but I hope it helps you all get where you want to go as you experiment.

ETA:  I accidentally typed Ghost instead of Wolfman on that opening line.  I apologize!

I could kiss you.

Thank you. This is one of the best nuggets of wipe info I've seen.

Yep I so glad we have a few of the Major Suppressor manufactures on here, to share their knowledge with us.

Also that they are civil to one another.

I still need to order a punch and a sheet....

Just an update to my earlier Wipe info.  I accidentally wrote the "Ghost" uses the 1" wipe when I meant to write "Wolfman".  I apologize for any confusion!  I've corrected it in the post above.

I picked up my Thompson Machine Neptune 9 today. It's essentially a boosted Poseidon 9. Same wipe setup as the Poseidon: 15/16" diameter, 1/4" thick, 50A neoprene. Mcmaster PN# 1290N373 is called out.

@HansohnBrothers I figure you could add this to the first post if that would help.

Long live the wiped cans!

With the red silicone and no center hole on my Ghost my wipes get pretty rough after 100 rounds or so.  After that it doesn’t do much.  A lot of times I’ll shoot 9mm for a mag or two then switch to 45 to make a bigger hole....

Anyone know the  GSL Pill box specs

Perfect for the Wolfman.....

A little off topic but, does anyone have a link or know the size of the piston o-ring for a ghost?  Thanks

Thanks Todd.
Found them on Amazon, all reviews are in reference to suppressors.  Must be an industry standard.

Rex gives part numbers instead of measurements to make your own wipes for the MG22:

McMaster-Carr item 5787T63 and Punch 3427a17

Where is a good place to get 70A urethane in 1/8" thickness and preferably amber color? Bonus points if it's available via Amazon Prime. Checked McMaster and they didn't have any 70A when I searched for 1/8" thick urethane.

Looking for a sheet of it to make some replacement wipes for my XM9 can, and also for another XM9 can we have at work.

I’ve been running neoprene in mine after Mageever recommended the material.
