m12x1 to m10x1 adapter

[Nee Zee]

This has possibilities...

FYI, I ended up ordering one of those from eBay and it turned out to be useless. The threads and insde diameter were fine, but the male side did not extend out far enough to grab the threads inside the moderator which are deeply seated. That was one parameter I had not expected. Thanks again for the suggestion.

I'm giving this up!

Here's an illustration of the issue:

On top is the Diana M10x1 threaded barrel

Middle is the eBay adaptor (too short on M10 side)

Bottom is the Sig M12x1 threaded barrel

How many threads of engagement do you have in your moderator?

Look at the photo, it matches the barrel that's on top (Diana M10x1)

The adaptor has to look like that barrel's end, but as you can see, it was too short. The moderator's threads are deeply seated.

Hate to say it, get a different or another moderator.  Or pay someone to machine an adapter for you.  What's shown looks like a plumbing adapter.  It's unlikely you will find something like your barrel end, unless it's made for the application.

Find someone that has a metal lathe, they could easily make it in an afternoon.  Actually this is one of the reasons I ended up with a small shop, so I could make various adapters and things for my airguns.

Yes, it's a plumbing adapter, but it's actually very finely machined. It would have worked if the male end extended further. Btw, "that's what she said".

I'd think that we have members that could help out that are nearer to you than me. 

If it were me, I'd make the adapter out of 303 stainless, if I had any in the right size.  It's stainless and it machines easier than the more common 304.  Or I'd pick 1144 stress proof which is stronger and machines very well.

No worries Bruce, I've pretty much given this up, not worth throwing a bunch of money into it.

Thank you Mr. Churchill.

If Matt can't help you out, give me a shout out.  When I get back home, I'll see what I can do for you.  Would have volunteered, but have been away a bit.  I'm sure I have some stock that will work, be it aluminum, or steel.  Brass is too expensive for this sort of thing, although it looks good.   Your plumbing fitting cost a lot less than what I can buy the brass stock.

Thanks for the offer Bruce, but Matt actually helped me out on this. He sent me one of his home-made creations, the entire LDC that fit perfectly and did the trick.

FYI, for anyone looking to quiet down a blowback pistol, I learned that these pistols will never really be quiet due to the blowback blast. Matt's LDC tamed the muzzle blast nicely, but the blowback noise will always be there.

Thanks Matt for your generousity!
