Watercraft magazine "Cordless Challenge"

[Paul H (admin)]

Tim,

That's clever - I wonder how efficient it is compared to a prop.

Well, we can try it out in the evening, even if I didn't get my entry in on time!

Tim.

If any of you kind souls have the technology to get messages from here whilst at the show, then I'd appreciate it if someone could keep an eye out for my arrival tomorrow morning, as I could probably do with a hand getting Aero off the car roof (it was interesting getting her up there this afternoon!), please.

I should be there by around 09:30, a white Prius with a big red boat on the roof..............

Jeremy

PS:  I managed to get a rough set of oars made, the mould broke getting the second blade out (my fault fo rushing things) but they are probably functional, if less than pretty.

PPS:  I have permission from SWMBO to stay on for a while in the evening (although I need to leave by about 20:00), so will join you all for a chat somewhere near the beer tent.

[Timmo]

No problem Jeremy. Leave boat on the car and come find us by the slipway. One of us can then pop back to the car park and help carry Aero in.

The ABBA boats are right by the front gate and the HBBR tent is next to slipway. So pull in to the left and park and stroll over, I'll probably be rigging Illusion.

Thankfully a lovely sunny morning to dry things out

Thanks for the help getting the boat off the car and an update on the trials and tribulations of broken gearboxes.  After some kind spectator decided to see if my propeller would cut the grass, by running the drill with the prop resting on the ground, the gearbox decided it wasn't up to taking the torque of a big Makita driving a prop embedded in the ground.  I thought that it might just be one of the two shear pin rivets that held the drive shaft to the gearbox together, but sod's law dictated that it had to be something inside the gearbox somewhere.  As the gearbox is a cheap drill right angle drive, embedded in filler and epoxy/glass, there was no way to get at it to repair it, so the whole leg is a right off.  

Being a Scrapheap sort of person, I raided my may-come-in-handy store and found another experimental drive leg, unfortunately with a 2:1 reduction gearbox.  This meant that the prop would be completely the wrong pitch, but luckily the electric Winsome stainless prop is a reasonably close match, so I bodged that to fit.  Three hours in the workshop, machining up a new drive outer leg, drive shaft and bearing, plus some judicious bodging with tape, means that I now have a working drive leg for the challenge tomorrow.

I'll see you chaps around 09:30.  Hope the rain doesn't make things too unpleasant tonight/tomorrow.

Jeremy

PS:  If the spectator who broke my gearbox today is, by any chance, reading this, then accept a virtual slap on the head from me...................

For those who are NOT at the Beale Show ...

Tim is through to the semifinals;
Fred Ball and Slade Penoyre (from AYRS are out)
Jeremy has a delayed first round race in the morning.

There are three reasonably fast boats (IMHO)
- a K1 sprint kayak modified into a trimaran, called The Yaksmith Bullet

with two drills under the outrigger beams
- a not-very-much modified white-water racing kayak called Four Candles
,
powered by three drills driving three propellors.
- a home-built trimaran called, appropriately, Fast,

powered by a single drill with a novel weed-shedding propellor.

Tim is I think a bit slower than they, but stands a chance if he can up his power.
Jeremy's boat I have yet to see in one piece, but it's beamier than the above and may be slower. I don't know how it turns - none of the three above are especially quick round the corners.

Leaving out Jeremy for the moment, my money would be on Four Candles.

And no one is more surprised than I that I made it past the first round! There's little realistic chance of my mirage drive bodge making it to the final. But that final could be a close run thing well worth watching! There's some seriously fast boats in the running.

The final was a superb race, the performance of the winning boat, Canute, designed and built by Tobias Vokuhl, was simply astounding, in my view.

My own performance was dismal.  In the rush to build a new drive unit yesterday, after the unthinking and moronic destruction of the original one by one of the show visitors, I made a stupid mistake.  I'd used a couple of grub screws to hold the new drive shaft to the new right angle gearbox input shaft.  The shaft had a flat on it to ensure that one of the grub screws had a good purchase, but I failed to check that the flat was aligned with one of the screws when putting it together.  The result was that the shaft spun in the coupling as soon as I applied any power on the water, leading to a complete failure to make any progress this morning, followed quickly by retirement.

To be honest, I doubt that I'd have been as fast as Tobias' boat anyway; he was almost on the plane on the final run to the line, definitely way above the hull speed to be expected from his relative short waterline boat.

I hope those of you on the Thames Raid are OK, the weather is pretty miserable and it can't be much fun battling against that cold wind.

Yes, if I'd been a betting man I'd have lost

I honestly didn't think it was that fast in the heats, maybe he was saving battery.
Fast burned out his drill (a Makita); Four Candles shed a drive shaft and prop.

A few pictures


Canute opened out an early lead in the final, so much so that he finished well ahead

leaving the Klepper and The Yaksmith Bullet coming in much later with the Bullet slightly ahead.


Canute was made from 5mm bendy ply (at least I think that's what it was, the grain ran vertically i.e. across the sheet) which took a lot of twist, especially the deck panel which ended up as a vertical counter edge. This is the best shot I have of it out of the water - my camera ran out of battery later.

You can tell I had also a fair amount of rain on the lens!

Hi This is some footage of the CCC taken on Saturday before the Rain Gods got angry.
