Been working trying to complete my two airguns. Spent a few evenings and the Saturday two weeks ago making new valves and polishing up the aluminum and brass parts.
I had wanted to do a lot this last week but was out with the flu for most of it. Missed one day of work and suffered through the rest of it.
I machined the valves long ago and they never did seal properly with the design I used. Went back to a tapered design and now the valves seal really well. Valves hold air for a long time rather than only a day.
The grip was to thick and I ended up machining off a 1/4″ on the aluminum and thinning the grips to suit my hand. Could make the grip even smaller but want to start bigger and work my way down.
Hoping to do more sanding and do the rest of the wood work next week for the remaining rifle. Then try to finish the walnut with linseed oil, never used it before so will see how the wood will turn out. Hoping to have the rifles completed before summer starts.
Performed a chrony on the rifles and the design looks promising for .22 cal pellets. I need to tune them a little as they are very close to 500 FPS, and I think I can get 800 to 850 FPS out of them but will see what the 1400 PSI regulator allows. I may need to purchase the 2800 PSI regulator & tank combo. Having said that, I may or may not have to register the airguns with Fire Arms Canada pending on what happens to the long gun registry.
