"In the world of spuds today"

That's pretty good!

There seems to be a lot of air coming out after the pellet has left the barrel. I was thinking something in the direction of decreasing the valve dwell time and making the diameter of the air path larger. Maybe you can enlighten me

Oh there's a lot that can be done!

This article is a good place to start: https://hardairmagazine.com/ham-columns ... ated-pcps/

In fact all of Sterne's articles are worth looking at, if you want the ultimate in efficiency check out the “Stopping Spring Guide” concept that greatly reduces hammer valve bounce.

In fact, the energy of butane vs. hydrogen. Interesting.

In the end I bought the red dot sight and installed it on the co2 gun. It is a Chinese sight, but it works well to play a little. It is made of non-plastic aluminum and the regulator is about 15 meters away. Quick to focus the objective, much more than with the open system of rise and point that the weapon brings. I just wanted to show you, although I have not manufactured anything of this weapon.

Winter is coming.
So we're going with solid-core ABS and aluminum for this build.

He's back at it anything of note or just scratching that itch?

I thought by now I'd understand how a combustion works, but I can't figure out why there are two camlocks on this thing. Also, is that an aluminum section in the middle? I have a soft spot for combustion cannons. Let's get some details on this creation...

Mainly just scratching an itch. Have some bigger plans but I need a bigger workspace.

Camlocks are just faster than threads. I don't plan on having to remove the 3" "endcap" one during normal operation, but it's there anyway. The aluminum section in the middle is because the only ABS I can find (even online) is cellular core.

I haven't been doing much lately, sort of got into building bikes

I have turned the BFG into a MFG, cut down the barrel , removed all the semi auto bits, cut the body down a bit and now using a diiferent gravity fed mag which holds 20 BBs

Started making a folding stock for the pump action, because folding stocks just got to finish the butt plate.

Whoa, that thing looks awesome. Looks like a sub machine gun, lol.

[farcticox1]

That's this one

[hectmarr]

It looks good, adaptation.

Just bought my first welder, looking forward to moving on from pvc!
Now I have to learn to weld properly lmao
What welding processes do you guys use? I picked up a titanium flux 125 on black friday, I was originally gonna try stick but the learning curve was intimidating and it didn't seem well suited for the thinner materials and more precise welds that I need for spudding.

Mig, Tig, both? 2 in 1 machine?

I wish! I had to settle for fluxcore, which is basically stick welding but the electrode is in a wire form. Luckily it was less than 150 bucks on black friday though

Got some practice with the welder by making a tool for the lathe. I've been needing a tool rest more suited towards the carbide tooling I use so I welded this together. The welds have really bad porosity but I believe that is because I was holding the gun at the wrong angle and I wasn't moving consistently enough.

Either way, it works and I'm getting closer to welding spud guns together!
