As the title says, I have an old direct thread form 1 can that I would use more if it had mounting options.

The primary blast baffle is an odd male to male piece with male 1.180x24 (Liberty) threads on one side and 1.375-24 (Hub) male threads on the other.

I need a 1.375-24 (Hub) female to female adapter to go from the wierd ass blast baffle to one of the Griffin or YHM mounts I have.

I haven't found an online shop that sells something like that, nor do I know who to ask to make a one off piece. Ecco has always been my go to for adapters but they state no custom stuff on their contact page. I  also dont trust my own lathe to be up to the task of making it to the degree of accuracy needed.

Any help is appreciated!

This piece wouldn’t serve any use?

In a recent thread Griffin said they don’t accept Form 1 cans in their Red Cross program.

I have that exact piece, and it would work if I wanted to eliminate the weird blast baffle. I want to keep it though, this can has  Aluminum baffles in the stack. The weird primary is steel, so it does an ok job of protecting them.

This is a form 1 can,  it is not the pinnacle of light weight or sound reduction efficiency.  If I can find or have made an adapter that makes financial sense I will, if not it will just stay direct thread.

The below pic is a poor photoshop of what I need

He rethreaded my Form 1 can so I could thread on a tri-lug mount.  And he accepts Form 1 cans.  Can cerekote too.  Really happy with the work.

Since you have a lathe perhaps you could turn a stepped steel washer that fits into the Ecco adapter if it would sandwich in place.  Or a simple conical washer.  303 stainless turns relatively nicely and is fairly cheap.  You might even find an 18-8 / 304 flat stainless washer you could adapt, but chucking thin pieces can involve fabricating a mandrel and chatter is still likely.

ETA:

I presume this is threaded on both ends. Longer than you want at 2.5”.  They also have in lighter weight anodized 6061.
