I have rifles almost complete minus the stock and wood.
I haven’t been able to finish all the page links but here are two new pages of pictures for the concept 4 rifle.

I hope to link all the pages soon. I have pictures from Schaefer on his new build and will post them soon. Thanks for reading.
After a very frustrating morning, I was finally able to get to the shop to work on the air rifles. I managed to get one of the rifles to fire by 8pm. On valve is leaking so have to work on that. Valves either work or leak and finding the perfect combination is tricky it seems. I realize now I should have made the valve a 2 piece design.
I worked on the triggers and sear. I had some springs but they are to weak and will have to get some heavier springs to make the trigger and sear engage more consistently.
Below is a video showing a few shots and first pellet shot. I will add to the web page when I can as I have many pictures to add from last 2 weeks of working on this project. The rubber bands are holding 1/8 drill bits in place to locate the trigger and sear and kept falling out otherwise.
Next few weeks will be focusing on the final machining and assembly as I can. Thus far a very mild fall here in Manitoba, but the snow and extreme cold are going to pounce on us very soon!

I have been able to do some work on the Buckley inspired reservoir airguns I am building. I have finished machining the valves, hammer and now need to make the triggers and sear. Hoping to have this completed on Saturday Nov 6th and should be able to test fire shortly there after. I will update the pages next week when I get a chance.
I added some pictures from October 11 to the page 5 of the Concept 4 airgun.

Hoping to do more soon and will post when I can.
I was able to do more work on the rifles I am building this past Monday. I hope to do more later this week and will post the pictures I have taken at that time. I have mounted the valve body on the action block and now need to start on the inner workings of the action. The hammer, trigger, sear, bolt and valve parts need to built. Barrel is ready to be mounted and waiting till all parts are completed for firing before this is done. The tight fit between the barrel and action will help ensure accuracy and do not want to take out the barrel to often and ruin the fit.
I was able to do a little more work to the Concept 5 airgun project. I hope to continue on the project Monday. I added more pictures showing a little more detail as to the building of an airgun.

I finally got a chance to work a little on the concept 4 rifle. Please checkout the page below to see some updated pictures.

I hope to do more in a few weeks. Going on 4 days of holidays this coming weekend and then hopefully be able to work a few evenings. I hope to be able to finish these rifles before the fall season.
I ordered a new 13 cu inch airtank with 1400 PSI regulator this evening. After spending time looking for the first one and waiting a little extra incase it would show up, ordered new. I misplaced the first one moving my office to my home.
I am looking at continuing with the Concept 4 airgun this month so that by end of the year it is complete. Sounding like I may have two weeks off over Christmas so would like to have all the parts ready to assemble and test the concept.
Be updating the Concept 4 pages once I get started.

Concept 4 – Reservoir Airgun
I have three German, .22 cal. barrels waiting for use. I have had the “concept 4″ reworked since the job shop that lathed the bore originally was out almost 0.025″ on the center bores. Would have made it impossible to close the breech area around the barrel. They fixed it at no cost by remachining for an aluminum bushing and then boring the 5/8” hole again to line up with the barrel. I am thinking of outsourcing the remaining build of these two air rifles as my time is so limited and not having access to equipment delays it even further. Might be the way to go, but will cost a lot of money to do so.
Rifling
I have ordered a reamer to try to replicate Clark Arms canted rifling. Clark has had much success with this process so should be trying it as well. Toughest thing for myself is to locate the pipe material. I bought some local pipe and when I picked it up it was black pipe, but on the phone the sales person said is was very smooth. Live and learn!
I hope to make a few 50 cal barrels and order some 50 cal bullets. A lot more commercial ammo to choose from using this size then going to a pipe that you cannot get ammo for and try to make your own. I will try to post more when I have made a few barrels. Please feel free to send an email at anytime. I answer most emails promptly when I can.
