To avoid confusion or indeed to add to it,i decided to merge this part,because they will form part of the bridge.
"Here we go again." One straight back, with slopping front and two sides designed for added strength.
"i`m sure the reason will become self evident by its end."___
Sometimes i change plans,so i decided to make do with one paper card support,which i believe is called an end-wall. This is expendable,and will soon be as useful as a bowl full of wet,dry sand.
" That`s an Oxymoron."___
" Yah,sure is, whatever that means."
" i`m confused i think."___
" Me too."___
" You 2 always are", said the accentric Cowboy who always in the true spirit of the Wild West sleeps in his boots."
An oblong tub.
Mrs B,keeps these for me to keep my truck in. The Kiln dried sand being very fine,but awfully dry,was wetted down with a couple a cups of water. No real mixing involved it was just left to soak in.
Sand placed in the bottom,and the tub was bumped up and down to compact it down .
"Yip that`s easy."
Kitchen paper roll stuffed inside the paper card box.
"It stops the sides from being pushed in by the sand. i think?"
" Yip,thats right. Well done."__
The sand is piled in.
" It`s like making sand Castles."
No ramming up to do. The oblong truck box is simply bumped up and down on my table top. The last thing to do was to level the top off, and_______________________
___ give the box a wiggle from edge to edge and side to side,and then remove the Pattern.
Glug, Glug the Plaster of Paris is poured in.
As the water was being sucked out of the plaster and into the sand, the top, which is the bottom shrunk a tiny bit, so I topped it up with what was left of the same mix.
" i`m confused,i think."___
See what I mean?
30 minutes later.The thingummy thing was removed.
____"i was expecting a muddy mess."____
"Yah,wet dry sand is pretty Cool even in the blistering heat of Texas."
The sandy end result two End Walls,for the Girder Bridge! No fancy walls needed here,just plain concrete. A brush off and any trimming needed,will be dealt with later.
A double rail-tracked bridge was designed and mapped well out.
A bridge that is still in parts upon the Cutting Table,can continue to take shape.
This shows the inner reinforcement added to each side of the bridge. Two will form each side of the bridge. There are more reinforcements to do later.
