.308 project, on going.
I have been collecting parts and drawing a design for a Condor type .308.
Here is what I have done so far.
Some notes:
1. Shrouded barrel, packed with Colbond Enkamat 7010 and slot vented.
2. Two stage trigger, with slide safety.
3. High flow valve, .312″ dia. ID., made from 360 brass body and 12L14 steel slide, with PTFE valve seal. 45 deg seal surface.
4. Standard Airforce tank, ordered from Airforce.
5. Tank mount, hammer mount tube, top rail and tripper mount from 360 brass, sweat soldered (4 pcs.) to make one unit, not bolts.
6. Front shroud made from 1.25″ OD x .0312″ wall 6061-T6 Aluminum.
7. Hammer brass.
8. Ordered custom wood carved grips and front grip (if that is what that piece is called), from http://home.comcast.net/~rlandres/AirGrips.htm , I tried carving, did not work out.
9. Using modified DAQ barrel, 27″ long.
10. Cocking handles both sides, (L&R) just in case. Using Mcmaster spring cat. # 9637K25, length TBD.
11. Hoping to use clamp on barrel bands (Term?) so no set screws.
Here is the trigger group.
Having never designed and built any gun before, what does everyone think. Am I old in left field?
Sorry do not know how to post a DXF file.
Let me know your opinions, good, bad or ugly. 😀

Your my freaking hero
Made some more headway.
Wanted to check parts fit with brass, once it works, then tool steel.
Little here and a little there. 😀
Finished the first molded parts this AM.
Not bad for a first try, OK a second try. 🙂
A fiberglass framed air gun.
If this works it will be something else.
Thank you for the compliment.
I am looking at using Duracoat, 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. The first try (mold making and casting) was less than spectacular (it did not go at all as planned) and I’m trying once again, will know tomorrow. That’s another ball game.
As work progresses, I’ll post.
Thanks again.
Its looking good JF 😀 , are you going to blacken the brass , paint it or make it realy shiney , your be the man with the “Golden Gun” lol
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 is an 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 pic did the trick. The reso is kinda low but you can save it and blow it up to see most of what you have planned. Thanks bud.
i have cad 2002 ? and a hi end camera , i can take a picture of the screen and have it in a simple picture format to post . or you could take a pic of the screen , few angles?
To answer the question about bushings.
I plan to have two bushings that connect the barrel to the aluminum tube. There will be another bushing that acts as a hammer spring adjustment.
Wish I knew how to post a better drawing. 🙁 Can anyone help with that issue???????
Like I said, many have ask for the drawing. If anyone can import a CAD file, you would then have a clearer idea of what I am trying to accomplish.
This drawing also shows bullet swaging dies (homemade type). Both .22 and .308.
Will both barrel bushing be in the brass section or will one be in the brass and the other be in the ali shroud? Or, both could be in the shroud I guess?
Been getting many requests for this CAD drawing.
If you request a drawing, you first need software that will allow you to open the file.
Meaning you need CAD software, that can import a DXF file.
I also need your email address, so that I can send as an attachment.
Please keep in mind, this is a work in progress, not a complete shop release level drawing.
You can get an idea as to the direction I plan to go, but you could not build directly from this drawing.
Also there is very little material called out on the drawing, material needs to be selected as per good design practice.
Other than that, your on your own at this time, maybe forever. 🙂
I am happy to send what I have to date, just keep in mind what you are getting.
This is the plan, brass rear parts, sweat soldered together to make an assembly. An aluminum tube will complete the frame forward, threaded to the brass assembly.

Looks real sweet Roy,
Are you soldering aluminium to brass? Hope you’ll succeed in that! I’m looking forward to the numbers!!
Regards,
Marc
Got a little more done last night.
As you can see, I’m making the rear frame from brass. I hope to sweat solder the rear frame pieces together, no bolts. I will be using silver solder, we’ll see how it comes out. 😀

I just saw you mock up for the trigger. The arm that the shoe mounts on looks like it will have play (creep) in it unless you spring it to keep it taken up. In doing that, you will be putting pressure on the next linkage in the same direction that it takes to break the trigger. Unless the uppermost part that catches the bolt puts enough pressure that it transfers back to the trigger rotating the middle linkage up. thereby moving the trigger shoe forward. But I dont think it will looking at the drawing. Good luck with this project. Hope to start my own Condor type project very soon.
I just found this site today and I have seen some incredible work here guys.
