There is a big difference between modding a gun and building one from scratch. I can't even conceive of the intelligences it must take to build an airgun but here are some beautiful examples.

COW!! Would you look at this. I have said it before...the talent that exists
in the airgun community is staggering.

Guns by Grant
|These two guns are not modded from existing types, but were hand made from Scratch, out of blocks of Raw material.|
|This first one is a little Micro -gun i made that fires the BACS ( Brocock Air Cartridge System ) I have made this one 22 cal. Its a single shot model. I will send you another one of my creations in a seperate email.|
|Made by hand from scratch. This is a replica, of a Girandoni Repeating pistol. Its 10 shot, 50 cal. Carries its supply of air in the grip reservoir.|
|These pictures are of another Homemade. Its a Webley type over-lever cocking pistol. Made from 4140 steel mainly, but has an alloy frame and Tyvar 100 grips. Its 22 cal.|
Hi Joel. Here is another homemade I built a few years back. It's my own design, not a replica of any thing in particular. Its 177 cal and modeled along the lines of the old GEM style airguns of the early 20th century.

|Homemade Pumper by Ron|
|This is a proto that is kinda sorta built like a tank. My mission was to
check out the idea of eliminating the air chamber exhaust valve and restrictive passages by means of sealing the chamber with a plastic disc. Ammo can be seen on picture where a side plate is off. (It is red with a pellet glued in place). So instead of just
performing experiments on the bench, I decided to do a complete gun that would allow for changes and incorporate new ideas as they arose. Rather than a long read, I'll just do some lines as to the outcome of this project so far. Feel free to ask any questions you want.
OA length = 36"
Weight = 7 1/4 Lbs
Barrel length = 17"
Pump stroke = 4 7/8' X 5/8 Dia
15 pumps gets a 14.3 Gr slightly domed pellet thru 1" pine board or 1/2" CDX plywood
|it is precision cut via a punch and die. The punched hole is .224 Inch so the slug creates a nice seal as it pushes the pellet down the pike. You will see the punch located at the exhaust orifice which is .187" drilled. On the barrel side you will see the U clamp that butts up against a stop block which the rear site is located on. This u clamp squeezes the plastic disc against the punch upon closure of the barrel. Inside the u clamp is the sliding die. This is what the hammer strikes to punch the disc. Now You pump the hell out of it and shoot thru a board. When the barrel is drawn backward via the toggle clamp to squeeze the disc, it needs only to create a little pressure against the disc. That's because the punch that is located at the exhaust orifice is really a little piston with a hole drilled thru. Upon the first pump the air in the chamber acts on this piston and the more you pump, the better the seal. Quite actually, the pellet needs to jump a .050' gap that is created inside the u clamp/die assembly. But that is all o ringed and works great. Thanks for the interest...Ron|
Brian's Custom Builds
|Check out these builds. Absolutely amazing designs and cool craftsmanship!|
first I would like to share is affectionally called "Old
It's a full length PCP repeater in old flint-lock style.
I combined a hammer/valve and a QEV wich I modified so every time the hammer/valve is struck, the QEV dumps just enough air for one shot.
Caliber is 16mm, I use steel ballbearings as ammo.
At 45 bar this thing has shot through a refrigerator.....7 times..
This smoothbore airgun is boltaction yet it has a flintlock..
Just one of the unique things I wanted to try.
I didn't like the fact that the hammer and trigger mechanism is housed in wood though.
So in 2011 after getting a welder and a lathe I decided to do things differently.
The second gun( : "The Sawed-off" ) I would like to share is completely built from scratch, valve and all.
It has a built in pump that reaches about 60 bar.
The valve is a counterbalanced hammervalve, which means the head of the valve stem is a piston which is not exposed to the pressure.
This enabled me to use a much bigger valve stem and opening, while still being able to knock it open easily at high pressure with a relatively light hammerspring.
After I had made the lever action, which cocks the hammer and reloads a 10mm lead ball in one go I was happy with the light hammerspring.
When the lever is pushed forward it pushes a rod back which is connected to the bolt.
This opens up the breech.
Once the reservoir is fully pressurized it will fire 3 good shots before I need to pump again.
It had a mechanism to push round balls or pellets out of the tube magazine on the side of the barrel.
At first I used a spring in the magazine but I decided it wasn't necessary and I simplified the magazine and took off the slugloader mechanism.
It put strain on the leveraction.
I settled on using leadballs and gravity feed much like a Girandoni.
I tried to decorate both guns.
