Unless I miss my guess, and we know that never happens

, that's a flat-8, not a V. Moreover, it has a simultaneous firing (stroke - in oarcraft parlance) sequence, that gives the distinctive power surge that has been the bane of oar and paddle boat NVH (Noise Vibration and Harshness) engineers. Though there have been numerous attempts to cure the surging, nobody has yet effected a suitable solution. Witness the disastrous effort by Colin Coxwain at the 1957 Cambridge-Oxford Boat Race where the Oxford crew showed up with a lengthened skull sported a full 12 man crew. A protest was immediately lodged and just as immediately rescinded when Cambridge discovered that the Oxford team intended to row according to the firing order of the Rolls Royce Griffon I (Firing Order revision 1). The staggered order (1-11-2-9-4-7-6-8-5-10-3-12) was designed to give maximum linear power with no surge and a smooth delivery unheard of in rowcraft. Of course, the inevitable occurred, and a missed stroke on man 3 caused a cascading oar clash that is problematic in an interference-design skull.
Oxford made it barely 30 feet before the fisticuffs broke out. Colin was banished, as was asynchronous rowing. Further study showed that Colin completely ignored the fundamental issues inherent in applying four-stroke technology to what is demonstrably a single stroke engine.
Further exploration has yielded the more modern synchronous-stagger stroke where the rowers movements mimic those of the common centipede, however everybody agrees that it's just really too creepy.

Piersdad, just so you know, what I wrote is utter balderdash. You're new so I don't want you thinking that there might be useful or factual content in there. There isn't.

In fact, you can pretty much assume this to be the case for anything I post.

And just for the record, that is a really cool row boat. Did you design that yourself? I'd love to see a video of it in action.

A laminated strip-floor ship. Awesome!

not really balderdash
this is the stuff that inventions are created from.
i have a model row boat that has over 15 years done some 100 km of rowing .
it was the sucessfull elipical movement of this mechanics that i have adapted to a multi oared boat

the boat is more finished now(no pics yet) with a grinning man on a throne on front deck with 2 levers that appear to controll the sweating men under the decks.
the whip man in the rear boosts the efforts of the 8 men
so it could be described as a
super charged V8 powered personal launch from 3000 years ago

at 71 years old and bored to tears i get into my workshop and just invent.
not wealthy enough to make electric cars now so just have to invent crazy things

here is a link to some of my other inventions like a prancing mechanical cat and a walking dirty sock

alecwolf the wood is cedar and i laminated several boards and then cut them into vineers.
(im a cello maker now) the cedar body shell was fibreglassed inside and out so it is ultra modern

Why don't you post an article with all your inventions?
If this is what are they about, it's reallly interesting stuff..

piersdad · June 29, 2009, 04:07:51 PM

wil do soon getting broad band today so this will make things sooooo much easier
here is a link to a tricycle i made for my disabled wife

and one of my mobility scooters nearly finished

Turn them into an article!!!

piersdad · June 29, 2009, 08:01:56 PM

ok as soon as i can just surfed all the resolved puzzles and got some ideas about inventions will start an article asap

piersdad · June 30, 2009, 02:48:20 AM

just found my idel car LOL

Dammit, you just had to take me semi-seriously didn't you? Now I'm trying to think up ways of creating an elliptical centipedal rowing drive. Let me tell you, it ain't nice. Nor is it pretty. Or working. Or anything but something that's bugging me.

Still... it would seem to me that it would be more efficient if you could devise a laterally synchronized rowing system that did mimic a centipede's leg movements. It would avoid oar collisions and, rather than all efforts being applied in one short burst, you'd have ... awwww see? SEE? This ain't right! Crappity crap crap crap crapcrapcrap. It was an off-the-cuff brain fart. It's not supposed to be right!

Somebody must have done this before. I'm not that bright. Or stupid. Or something.

Let me google it and... oh jeez... huh.... lookit that. Well, I guess I'm not the only crackpot out there.

porridgehead · July 01, 2009, 12:05:00 AM

Danke. I'll take that as a compliment, largely because I'm pretty much black Labrador in demeanor. The dog, that is. As in easily pleased, happy for any attention and a bit of a drooler. Don't mind free meals either. I'm especially content to have other people clean up the crap I leave behind.

Ummm... perhaps I didn't think this through.

Again.

Honestly, should I be alarmed that nearly everything I write starts out decently enough only to end up in flaming splinters of pestilence upon the picnic grounds?

Naaaah.

piersdad · July 01, 2009, 12:11:32 AM

thanks for the pic porridge you have got me thinking it only took me 3 months to develop the oars mechanics and about 3 prototypes so now i am inspired to create the centiped action which would really take a crackpot like me to invent.

onlyjust finished a flying mail box mechanics but a centreped could take a bit of thinking but not impossible.

How about a rotating bit of piano wire, bent at the appropriate angle, moving though an arc defined by an eccentric opening in the centipede's "skin"?

piersdad · July 01, 2009, 03:45:51 AM

the oars are the problem the ends have to make a elipical movement as well as a horizontal arc.
atm i am thinking of a tilting beam so that the oars are progressivly diped in sequence but the other back forward movement is a lot more complex
how ever i may set up your idea and se if there is some way it can be used

Otto Puzzell · July 01, 2009, 03:57:59 AM

The piano wire would be mounted on the face of a rotating disk. If the arc of the disk were greater than the ellipse of the opening at it's greatest dimension, I believe the tension of the springy piano wire would press it against the edge of the opening. The shape of the opening would define the movement.
