I have to admit, the bringing in of the "Super-saw", kind of surprised me...
250CC motorcycle engine. Neat. I want one.
Now "Some may say" that the Stig has a bigger toothbrush than that, his being a V8, but, on discussion with my kids, how bloody heavy is a 250CC motorcycle engine anyway... add in a oil fuel and possible coolant reservoir, 250CC is pretty large for as hand held engine.. we believe thats just about right for a demonstration machine, wouldnt want to be using one all day long.
So after all that, its down to the chain speed, and what that can impart to a solid object, that isnt too stuck in the wood to flick its self out.
I suppose, if its a recent hole, and you get the trajectory "Just right", it could come back out the hole it went in with, but thats going to be a 1:1,000,000 shot isnt it?.
And then all the bullets seen tumbled in flight, which we know from previous shows, slows them down anyway.
Faster chain speed?
I know from my days in motorcycling, there is a definite end at which chains can operate safely, and its not going to be anywhere near what you could call sub-sonic, because then a snail is also a sub sonic animal.
conservation of movement, I cant see a chain imparting a faster than the chain is moving speed to the bullet?.
So even if you could gear up the chain for more speed but less power...
..Final verdict... at this time, this is still busted.
The chimney cannon thing.
I laughed at the first "poof", and buster2.0 rising about a foot-and-a-half.
The final "Lets ramp this up" was only ever going to go one way wasnt it?. but it needed doing, and proved the point nicely.
But on that, buster just stayed where he was whilst the chimney failed around him and then just observed the laws of gravity?..
I would have thought he would have got a little more lift out of that?.
the hot saws are air cooled, but if you want to ramp it up:
we've got what you need. - now bear in mind the chain and bar are from a commercial timber harvester - I saw one the other day, and the teeth are about the size of my thumb. the chain still moves at about the same speed. if you want a seriously high speed cutter, you want a feller-buncher blade - but those are a circular saw.
chimney cannon: they should have had a scale, but it looked to me like the ramp-it-up actually did have enough thrust to get him above the top of the chimney.
