Nah, it needs more....
like jets!
So we can improve on the old swing.
Well I've already made a 360 swing in the garden.
It was hooking massive, It goes upside down, it was brilliant, but I'm thinking we want
to feel like we're flying.
So we need a bit more freedom, rather than just this and this, we want to be able to
do this, this or this.
Like the rope swing but with power.
Yes, now of course you've seen the thumb nail.
You know where this is going.
We're gonna get ourselves a pulse-jet, and then we have one of the bicycles that never
got chosen for the electric drift trike project.
So we're gonna get on it, to a big crane, then we're gonna ride it.
It's a blooming good idea.
Let's start trimming up the bicycle and attacks-ing it, attack, attaching it to said jet.
Very nice, look at this, plus jet and you can, do a little bunny hop on it.
Now then, I've fixed the forks on it- it wasn't gonna do that because I was going to use that
as some sort of steering system, of potentially having a sheet of metal at the back here,
and a bit like a rudder on the back, so it can direct the jet forces in said direction,
but I thought, wait a minute, I might be getting ahead of ourselves there, let's just, let's
give it a try without that first.
Now what we need to do now, we're going to suspend this from a rope.
I don't want a rope coming up in front of my face, wah!
Bar out here, and then go up above my head, so I'm kind of inside it, be hanging like
in a big C for Colin.
How hot are my feet you're gonna get, ha, I don't know.
If I start to get hot feet, I'll just do this... yeah just get on with it Colin.
Right, so for centre of gravity, we've got this, highly adjustable, swingy pivot thing!
I've no idea if any of these are going to be in the right place, because it's all guesswork.
Right, gas bottles mounted, very nice next thing I need some controls for the gas, so
I'm thinking I'll
mount a few valves down here and use the brake lever as a throttle, and then, give it a test.
Ok, she's ready!
Got a wonderful little throttle system look.
So then we haven't got any steering but I'm gonna go and give it a preliminary test just
to get a vibe for it, see what it feels like.
You never know it might not need steering, in fact it might need a lot of steering, yeah!
argh!
it's not very light!
We got all the stuff, Well Tom has!
We, haha!
We need some, uh, some protection from the fire!
This is a prime example of our excitement overrules function, because I know pulse jets
like the back of my hand, I know they get hot and I know if you over gas them they turn
into massive flame throwers.
I just wanted to have a go!
OK, so this is the Burnt Colin machine, so I'm thinking we need some sort of a heat shield
to stop me burning my feet and then as we're running this on gas not liquid gas we could
just have a solenoid valve on the gas, so if it all goes horribly wrong I'm gonna just
flick a switch and hopefully the flames stop.
right we'll have another test.
Full belt on gas, no good!
Not enough power.
So it seems the solenoid is too restrictive, so we're gonna try a liquid gas bottle and
see if that helps.
No this is just as problematic, we've got erratic flow and he's trying to set fire to
me again.
Ok so took the solenoid valve off, now this worked brilliantly as a kill switch but you
just can't get the flow of gas through it, so it's causing me too many problems, so I've
added this little simple solution.
Right come on, take three!
Do not set fire to me, and work!
I think, it would help if I had some slight direction with the steering, but you
still get momentum, so I think we're gonna go away, put a little bit of steering on it,
and then we'll go right up high with the JCB, hight as we can go.
and also do it at night cuz this thing glowing red hot, woohoo!
Yes!
