AES, made of Tungum actually, go on tell us the story pls.....what ever it is.....
I find the 1/2 guns either battery or air powerd heavy enough.....
I really bought my 1/2 batt jobby just to work up a ladder /scofolding just to put the new shed together.....m20 bolts top n bottom of stantions......and not drag airlines around.......
I know everyone slags of the Chinese but without them most DIYer's wouldn't have air guns at all....let alone batt ones.....
have a good weekend.....
@clogs: OK, you DID ask for it! (Sorry for thread drift everyone).
Tungum is an alloy, primarily of aluminium, brass, silicon, nickel, and I think copper as well (can't remember the percentages). It's about 100 years old now I think, and a Brit invention. It has 2 very important properties, A) it's very good at corrosion resistance ("proof" against just about anything!), and B) it's structure remains stable even at v low temps.
When I was in the RAF, the aeroplanes I worked on had liquid oxygen as their primary crew breathing system (only the standby/emergency system was gaseous, in a bottle). As I'm sure you know ("shattering bananas", etc?) liquid oxygen ("LOX") is VERY cold (can't remember how low, but VERY low temps!). Out "on the line" (where they parked between sorties) we used to refill the aircraft systems via a small 4 wheel cart which carried an insulated "flask" of LOX. But those carts were refilled from a static supply located well away from everything else. That was piped with this Tungum stuff.
In some areas of the structure it's also used in aircraft hydraulic lines (but much thinner/smaller OD than the stuff I got)!
Apart from the above properties, Tungum is very stiff/hard to bend, and from a mate I got a length of "thick-walled tube" about 3 feet long. The ID was a snug fit over the tommy bar of the above-mentioned three quarter drive socket set. Worked like a charm when I "stood" on it on all that my bloody VW van could throw at it! It, together with the socket set and the "bash-it" impact driver went along with the VW van when I sold it on. We really are talking MANY years ago.
BTW, while I'm wittering away well off topic, I wonder if anyone knows at what point (what size/s) "thick-walled tube" officially becomes "hollow bar"? I should know but don't.
Cheers
