Never made a home built air gun before. Thought I'd give it a try. Not a great photo, hard to convert a CAD drawing to a JPG, or maybe it's just me.



This is a photo of the valve I have made.



This shows some of the frame pieces.



I'm not fast and I'm not good, just trying.

If you have any comments, I'd like to hear (OK read) them.

Thanks

looks like its based on the AirForce design? Then, did you do the drawings yourself?

Nice looking pieces you've got. I'm interested to see your progress too.

I saw a photo of an Airforce Condor and it looked like something I could pattern after.

Yes I did the drawing, I need that to make parts and hopefully they will fit together and work.

I have a CAD program called Ashlar-Vellum, very easy to use.

I'll let everyone know how things progress.

You have a great site, glad to have found it.

Hello everyone, thanks for the remarks, comment and ideas are solicited. I alway thought "that beyond my capabilities", means I have not tried that yet.

As I said, I'm not fast and or good, but I try, failure option and is a step to getting it right. Some more parts have been made.



The valve is complete, the scope rail is complete, the valve mount is complete, the forward frame mount is complete (brass tube), the lower frame (trigger mount) is ready for the hole that locate the pins for the trigger mechanism, the front frame (aluminum) is ready to be drilled for the barrel mounting bushings and the nose plug. They are shown in the order of assembly.

Next on the list is to make the trigger parts (lots of small detailed parts ) and finish the trigger mount.

I'll post as I get more items in progress.

Thanks for looking.

That valve looks fantastic. Very nice work.

How will the scope rail be attached?

Thank you for the compliment.

I am looking at using Durcoat, I plan to cover everything. I plan to use this for hunting and not shiny is better, IMHO.

The reason I made the parts from brass is, I can sweat solder them together and not require bolts and such. I think it will be more rigid and easier to assemble, time will tell.

I'm also working on molds to make an assembly out of glass fiber reinforced epoxy. That's another ball game.

As work progresses, I'll post.

Thanks again.

I'm an ex-electronics worker and I've done a lot of work with solder and have found it to be
very poor mechanically. I don't like the brittleness of the newer 95/5 solder. (95% tin, 5% lead).

But I have almost zero experience with soldering large metal parts together. Just copper plumbing pipes in the house.

I know the sight on the muzzle of my Ruger Blackhawk is soldered on (silver solder?) and it's on there
like it's bolted in place. It would take a big hammer to knock it off..

Wow, Induction heating Brazing Brass to Brass is neat process.

I know what it's like to heat up 1" & 3/4" copper plumbing pipes, and it seems like
you are going to need a lot of heat to get that brass up to temp..

I'll be watching for the updates as you work..

Cheers,
Rich
