The other day, I got my hands on a YOSHIMURA silencer for the Impulse 400 TYPE-C.
I definitely bought it for this engraving.
Should I just use the outer tube?
Of course, we don’t take on work like that.
If you ask a custom shop or machine shop, they should be able to handle this kind of work easily.


It looks like they really wanted to get the front part off somehow—it’s in a scorching hot state.
When I looked into it, it’s supposedly non-disassemblable? Is that even a thing? I wonder how they got the wool in there? The mystery deepens.

Since it’s mine, I just went ahead and cut it.
I used a metal saw to cut it, but it was barely better than a contour saw.
If we were doing this professionally, we’d need to make special tools, which is why we don’t take on this kind of work.


The cut end is pretty ordinary. It was just inserted at the tip, so it came right off.

It was very dirty, so I cleaned it with wet blasting first.
The stainless on the insertion side won’t budge.
At that point, I guessed it might be stepped.


I can’t hit it, I can’t use a press… I wonder how it fits in so tight?

I imagine all sorts of things, but in the end it turns out to be pretty ordinary? ( ゚Д゚)

There’s nothing left but to push it to the limit on the lathe.
I’m chucking it at the insertion point, leaving just a fraction of a millimeter, and going hard.

I relieved the cut area to the inside and tapped gently… tap, tap…
Oh, it came off.
Wait? It was press-fit?? That’s the punchline.
Well, silencers like this have always had aluminum that loosens up quickly, so maybe they used this method to account for that.


But why press-fit something so tight at the end?
Or did they press-fit the cap first and then weld the shell at the end? But then the wool would burn…
Would it be okay at aluminum’s melting point?

So I managed to keep the outer shell (‘ω’)ノ
Now I’ll make the internals ~(*´ω`)
