You know I can see how that would be more addictive than CRACK, haroin, meth, but not quite as bad as Camel cigarettes or cigarettes in general. Also be as expensive as gambling, ex wife's, ex girl friends, and getting old. Yet I'm betting it's a big a blast as the first girl friend was, until she found someone else that had a faster tank. Lol very nice hoard of big boy toys you've got there, and I have to say I'm jealous, but not jealous enough to go hunting my own up at this point in life. P.S. Wouldn't it be less difficult if you let it come up to temperature, and then she'd idle down for you to move her about without the lurching as she's doing inside the shop. Just me thinking outloud, so never mind me, cause I do it all the time.
Saw a fan of yours post on DeBoss Garage's channel on their recent video with a collaboration with Nicholas Moran on their "Truck Tank", about your channel. Thought I would come by, say hello, subscribe, and enjoy this. Cheer's from Deadmonton!
I believe it is for the air starter. Like the electric starter for your car, but using a pneumatic motor to turn the engine over. The soviets made a lot of use of air starters, as they were more reliable than electric, especially when you factor in the cold weather they might require a tank to start in. You put in 150 psi, you get out the same amount of power, no matter what temperature it is. Electric batteries on the other hand, have greatly reduced output when cold. Another benefit of Air-starters, is that they simply cannot overheat, unlike electric starters. So, as long as you have air supply to the starter, you can crank an engine over, with electric? Your starter is going to be hot after 20 seconds, and cooking itself after 30 or 40. So, yeah, old Soviet tanks and a good chunk of industrial equipment will use air-starters.
