Well done Squib! and welcome to Spudfiles.

The design of this one gives me "STEN" gun feels.

Hope you're all well, Isolation is allowing me some time to look into doing a project and along the way I've come up with another solution to the ROF problem in BBMG's. This solution does not use any pressure, springs or bolts but rather uses the initial exit motion of the pellet/bearing from the ma...

Thanks Jack. Great info as always! Is that video from a pellet or BB gun?

I'm sure at some stage we've all thought about it and I'm always trying to push boundaries. So here's what I've come up with, instead of using a short, narrow piston to fire off a single pellet, what about a long, wide piston (like 40-50cm) with a powerful spring drawn to the rear to create the powe...

I’m pleased. I went ahead today and bought two part epoxy putty, unfortunately the wrong type (steel). You would think a warm mouldable substance would curate like crumbly play-doh, wow, how wrong was I? This stuff cured, WARM, in about 15 minutes and after an hour, was virtually indestructable. Imp...

I made them from epoxy resin or polyester resin. They come out perfect when using a mold. If you leave a hole well centered, and then, when the curing is finished, temporarily stick a metal shaft, and make the slot for the oring in the side hole-making machine. I use it in a 5X hybrid, and it has n...

Have you considered 3d printing an adapter to fit inside a section of PVC pipe so that you can use a regular drill to turn it? Even more advanced would be to use bobwombles 3d printed 3 jaw Chuck to hold a coupler or section of pipe to be turned. Many times. But due to the nature of 3D printers reg...

Beautiful! Welcome to the forum!

Hey team, struggling to find a way to precisely create a PVC-on-PVC piston. It has to be PVC on PVC because I need it to glide and seal pretty darn well. I've found some couplings that fit pretty close inside the 25mm PVC but without a lathe or pro routing tools... it's hard to get anything close. S...

Just a quick note that the above download link will expire in about 12 days so there will be a new file destination of mediafire.com, speaking of which, this new RAR will give me a quick chance to update. This weekend I will: - Add a second type of QEV, with the exhaust on the arm of the Tee - Add t...

I’ll fix it at some stage. For now I just want a functioning app!

This thread is for my PC app, the Air Gun Design Program. This app lets you create designs in real time and offers a variety of editing options. Release: 1 Oct 18 Status: Receiving feedback, Beta Version: 0.3 Update details - 2 new canvas colours. Black and White - Save and delete mode fix. Couldn't...

So I didn't manage to get all the work done by Sunday (my time zone) but the Beta will be released for trial *tonight*. Good news. I will open a new thread and will take questions and answers plus more suggestions there. Thanks!

not bad grouping. Are you happy with the accuracy and speed?

Won't be going that far out of sheer laziness. But hopefully this app will help people work out what they want to do, and then go from there.
