Did you build the gatling gun yourself?

For the Y dimension, choked flow plays a very major role in overall valve performance I think.

The main question is, how small a value Y could be in order not to adversely affect performance too much?

And thanks for telling the dimensions, helps those a lot those who want to build their own high-powered valves (like me 8) ).

I especially like your idea of using a hardened screw. The stem looks a bit thin near those three holes, hopefully it will last after hundreds and hundreds of hammer strikes. May I ask what…Read more

.357 / 9mm, is a nice intermediate caliber.

This barrel is cheep , $27 +shipping. It has 10 grove rifling that works good for airguns.

I took a CNC course a few years ago, it was a year long and in that time I learnt the 5-axis lathe by heart. It helps to have some programming…Read more

That would be a good idea if I weren’t a student with little money and only limited chaces of using the machines. So I’ll go for the beast first…Read more

Sorry, but if you want to hit anything at all you’ll need a rifled barrel. I suggest you contact Don G. (shrpshotr28) about it, he can give you excellent advice. Second, the valve….I know close to nothing about valves, but I know the valve GOD, Sean… (blodnob)…Read more
