Did a little testing, "mouse fart" achievement unlocked :D

Also tried a suppressor I made for a 22 rimfire, worked almost as well in spite of the larger bore of the baffles.

Point of impact changes but group size remains the same. The problem with this design though is that as the barrel is essentially the hammer, thrown back with considerable force at every shot, coupled with the heavy trigger, accuracy is quite relative :roll:

Another one for the Shinsung, this one was made as a display model for a friend who owns a gunshop in the hope of generating some interest :)

Is that actual carbon fiber or just a really convincing stick-on decal?
Looks great either way. You really need to add some composites to your arsenal of materials. They're really useful for frame and bodywork.

I believe it's real carbon fiber tube. You can find it in good hobby shops for making kites
:)
Composites are very nice materials, but very difficult and messy to machine imo :D

Cheers dude :)

It's the real deal, why would I mess about with fakery :)

That's what I'm finding out, once you get over the initial shock of the cost of the raw material it's brilliant stuff. I have some CF penguns in the pipeline, watch this space!

The trick is to use them in a way that machining is not so necessary. In this case I cut it as straight as possible with a saw, then after adding the endcaps I spin it on the lathe and finish it off with sandpaper. Not too keen on the carbon dust that's generated though, I reckon that would screw with circuit boards pretty quickly - so I use a vacuum to scoop it up immediately.

Well it covers all the material costs by a long margin and the time actually spent machining is quite low, besides it's something I enjoy. I could ask for more, but would definitely be selling less, which would be a shame.

They look amazing JSR! Definitely compared to my .50 cal QEV Cannon's suppressor, which is a pice of copper tube shrouded in a piece of plastic pipe! How much does the CF tube cost you?

It might look cool to have a sealed section at the end (meaning it wouldn't exhaust any air) and have some holes drilled in the end cap.

Works out at 0.68 dollar cents per centimetre, so say for a 20cm tube that's just under $14. Since I would sell it for $100, not really a problem :)

This sheepsha...er...kiwi *ahem* does some pretty good work:

Did you mean something like this?

I'm trying not to make them too fancy though to be honest, because just like the proverbial fly in the soup, everyone will want one ;)
