THIS MORNING WE CHRISTENED OUR SHELTER 'SINE', NAMED AFTER THE SINE GRAPH. MARK STEWART, THE PROUD FATHER IS VERY HAPPY WITH THE DECISION AND CAN'T WAIT TO GET TO WORK ON HIS BABY.
Mark's original idea was to use chamfered timber fenceposts, held together in an arch by a keystone, and he is adamant that this is the solution. However, Graeme and Jerry, ours tutor who are seeing over the design are not so keen, believing that the keystone will appear 'tacky' and 'Harry-Potter-Esque'.
Graeme and Jerry put forward some other possibilities that would hold the structure together.
These included:
-A steel cable running through the timber beams, holding it in tension
-Filling in the capillary gaps with some kind of caulking (similar to that used in American log cabins)
-Adding a concrete bench, which will act as a truss - a bowstring truss to be specific
-introducing bicycle wheel spokes running along the back of the wall, holding the structure in tension
soooo.....
After lunch, Mark and Ed went to the workshop to mock up some of the options to scale in order to determine which structure worked and it was finally decided to go ahead with Marks initial suggestion of using the steps all interlocked with each other and held in compression with the possibility of a steel cable running through it to hold it in compression.
Andy and Aidan spent the afternoon visiting various timber merchants so as to research into which timber and in what size we should go ahead... results to follow!
The rest of the group brainstormed ideas for fundraising as this was one of the major aspects fo the project and with mark's intial guesstimates coming in at upwards of three thousand pounds, even though the scale was reduced, the size was still very large.
Kaleena and Bhavina decided to go into town to seek out sponsors for the raffle and the Sine structure on Tuesday with the possibility of having sponsor's names engraved onto the shelter steps itself.
