Kiwi's Thinking Outside The Box

Here are some pics of the Mk 1 Seagull twin.

And I thought "Charles" Heath-Robinson was dead.

Not me that's more of Raoul's work.

Don't ever mention me in the same breath as anything Kiwi, or I'll be clouting you with my gauntlet & meeting you at dawn!

To defend whatever honour I have left.

So it's not true that your secret skunk works team working on the worlds first "Deltic" Seagull engine to crush everything in your wake.

How about a Seagull Square Four"?

Here are some pics of the Mk 1 Seagull twin.

The photographs are 'no longer available'.
Are they of the boxer configured engine I've heard of, and if so, is it possible they can be reposted?

Pinger these are the only pics I can find, this is the twin on a hover boat, this is the work of the mad professor at his worst!

Sorry it's not a boxer but just a "side by side" like an Anzani sport twin.

The "mad Prof" stole the hull design from the Death Star!

Note the electric fence to prevent escape attempts!

Thanks Charles.
Presumably, at least one of the bushes in each engine converted to rolling element bearings - to counter the pull of the chain.
PS.
My plans are still so far up in the air I might end up with an aeroplane engine....

Quite a secure containment area, I'll see if I can get a picture of one of the armed guards, this place is the New Zealand equivalent of America's skunk works!

Interesting thread. The 'Kiwi" moniker attracted my attention.
I am thinking along the lines of "why re-invent the wheel"?
Some 10 years or so ago a British marine engineering company connected to the off-shore cigar racing boats gave a couple of new interns a 105 and told them to perfect it, to see what they were made of, - the interns not the motor.
Comments of ' out of balance', built like a tank, crude casting etc come to mind.
Anyway the 105 was skimmed, polished, tuned, ( spun at 50,000 rpm etc ) to the highest degree imaginable.
All components original and when tank tested , the 5 hp was developing 15 hp.
The only problem was the crown wheel could not take the extra load /speed, and overheated and shattered.
A higher grade wheel was machined to overcome the problem, the only non-standard part.
Because of the thinned walls etc, it was estimated that the motor would run for approximately 15 hours before exploding.
Shipped to God's own and put on a 16' Tinny for testing.
At 35 knots the driver chickened out as the boat started to do a 'Bluebird".
His dream of breaking all Waikato race records went down the gurgler.
Unfortunately a garage fire destroyed the motor before it could be fully put through its paces.
So, perhaps you do not have the equipment to spin out the parts at 50k,- but a good balancing of original pieces might be the ticket and not installing alternate parts?

Not sure what a 105 is, don't think it's a seagull.
