Bridge for Lazy Grange Bay II Empty
PostSubject: Bridge for Lazy Grange Bay II   Bridge for Lazy Grange Bay II EmptyThu Nov 05, 2009 3:34 pm

Mr Duffy requested a bridge to gover the newly instigated lake at Lazy Grange Bay

After much "umming and aahhing", measuring and research, work commenced.

Mikes bridge needs to be 42" - That's 1066.8mm....

Needed 2 off 20mm x 40mm rectangulat steel tubes - Guess what? - They don't stock this size in the UK - So got 2 x 20mm x 20mm and welded 'em together

Pic below shows welded , then filled with car body filler, then with a spread of cellulose filler

Next up was to mark up for horizontal supports (It'll come clearer when I get nearer to completion

Bridge for Lazy Grange Bay II IMG_9108


Bridge for Lazy Grange Bay II IMG_9109

Hacksaw on the marked out lines 6mm deep

Then attack with the angle grinder to remove metal between hacksaw cuts

Note:- I put me glasses on - Not to see more clearly, but to protect my eyes

Bridge for Lazy Grange Bay II IMG_9114


One set of uprights brazed into place

Bridge for Lazy Grange Bay II IMG_9115

Another 10 uprights to do and then some paint - NEED to find some stainless steel / aluminium mesh for the walkways

Bridge for Lazy Grange Bay II IMG_9116

Latest update so far

Needs a spot of rubbing down and filling first and then on with the paint

Need to make the walkways next

Bridge for Lazy Grange Bay II IMG_9119

Here it is, painted up with that yucky "Ford Signal Green" that Mike bought

Bloody 'orrible it is

Never mind - got a better colour to go over the top

Bridge for Lazy Grange Bay II IMG_9124

Just made the first of the 10 pieces I'll need to create the walkways.

Not difficult to do - Just time consuming...

Full length of one piece

Bridge for Lazy Grange Bay II IMG_9127

And a close up - I've used the mesh that you can get for doing car body repairs. Would have liked to have made just 2 full length walkways......

BUT - 1250mm x 300mm of 5 x 3mm aperture = £23! The mesh I've used was £1.69 each for a piece just a bit smaller than A4.

'Tis finished

And to give a sense of size

And finally a couple of pictures of the bridge in place

it fits perfectly, its resting on stone pillers, sunk in to the banking, riseing up the banking, i think you could park a car on the bridge, its that strong..

ta guys, just a point off possable intrest, the watermill, came with a electric motor, to power the wheel., and a loverly( Laughing )plastic base....well thats too easy, and it looked poo...
so, motor removed, bit off research, and a lot off fetalling.. now its water powered, a truely, undershot water mill..more details if intrested.....

Nice work. I like the waterwheel too. I was curious about the sluice gate in the pic above - did you make that or was it part of the kit?

It’s part of the kit Clive as I have one with mine.
Yes I would be interested in how you made it work Mike, for future reference.

i used a plastic gutter as the river, and base for the undershot bit.. glued in plastic L section, to form a chanle, 1 mounted on top off a nother, made the drop, to fit the wheel ,and glued that in plasce,

the wooden wallkway is sipmly that, bit off wood, lines scribed in, sat in the by pass chanels, the sluices gate regulates the flow,
this vies shows the drop, before i detailed it

Nice job! So, not only do you run your own railway, you get to mill your own flour! Cool

I like it!
Definitely the way to go with my water mill, I will just have to work out a position on the overflow stream from the canal.

Hydrology 101:
Water wheels (undershot and overshot) are driven by the differential head (engineer speak for change of height) of the water, not the flow of the water per se, converting the potential energy of the head into a more useful form of mechanical energy. Same with turbines in hydroelectric dams. A river flows as the result of differential head (typically changes of meters over many kilometers except of course for phenomena such as waterfalls) having been converted into kinetic energy.

One could design a device to capture the flowing (kinetic) energy of a river, but it would probably be closer to a windmill or a paddlewheel on a steamboat in concept than a water wheel.

Class dismissed.

Bill: were you a physics teacher in another life? That's the most succinct explanation of the relationship between potential and kinetic energy I' ve ever read: my school textbook took about three pages to cover what you did in three sentences.. cheers

Phil:
I am a Chemical Engineer, so hydraulics is something I deal with daily, although I haven't seen many water wheels in our plant lately. Thanks for the compliment; I seem to have a knack for explaining things in succinct terms. It is likely the result of many years of working with others for whom English was not their native tongue.

Eschew obfuscation, I always say. Very Happy
