Custom part: semi auto

The actual machining isn't that labour intensive.

It's building jigs and fixtures to hold the part for each different machining operation that takes the majority of the time.

Then you have setup time for each machining operation, the actual machining process, cleaning and de-burring, assembly, testing, packaging, trips to the post office, etc.

Add on costs for electricity, materials (and shipping of), and tooling (cutters($30 and up), drills ($5) and taps ($8 and up)).

When it's put that way, 50 euro is starting to look not so bad eh?

And from whatever he manages to keep after costs, the government will invariably want "their" share of.

Truth be told, I bet he just likes the smell of hot cutting fluid.

Lemme guess, a hammer valve which cocks by pulling the trigger and compresses a spring, and it releases when the trigger is fully compressed?
And if thats wrong I have a 2nd guess:
A hammer valve which is powered by a small pneumatic ram?

It would certainly be a very good idea if you can manage to ship a bunch over to BCarms so that he can distribute the valves in the US.

Wow, 50 Euros is a lot. Unless the perfomence is spectacular or the US Dollar gains some weight, I would not want to pay over 50$ USD.

However, I say go for it, advertise here and on youtube.
I won't even try to guess how it works w/o a hammer or spool or batts. Is a sleve valve the considered a spool?
