My husband and I offered. This is our biggest tent to date – the internal floor area is a bit bigger than 8m x 4m and the space between the poles is 2 canvas widths – 4m.
Guidoriccio da Fogliano (detail) 1328
Fresco by Simone Martine
Palazzo Pubblico, Siena
One day I”m going to make one that looks more like this, with the stripes and the crows feet wall guys and the rectangular doors, but the Innilgard tent was a good start.
We did quite a few new things with this tent; Innilgard wanted removable walls and we used a finial based on the extant one in the museum in Basel. We also decided that we should provide 3 storm guys per pole, like in the fresco.
This is the plan and elevation I prepared so that Innilgard knew what they would be getting.
This version also shows the layout of the leather grommets around the roof eave for the guy hooks to go in. After making the circus tent with alsomst random guys points, I knew I wanted guys at each quadrant for this one.
When you include space for the storm guys at a 45degree angle, you need a rectangular space at least 12.4m x 8.4m to set up this tent.
We decided to make 6 separate removable wall pieces, to give as much flexibility as possible. To allow for the curve, we ended up with 2 rectangular pieces and 4 curved pieces.
This picture also shows the layout of the roof, with all except 2 seams sewn.
Here’s a picture of the wall connection technology;
We sewed the loops onto white tent tape and then sewed the tape onto the walls.
The toggles were sewn into the eave seam.
James made a jig with a piece of wood and nails to measure the distance between loops and the depth of each loop. He would thread the cord around the nails and then mark the distances with a marker before sewing.
And here’s a picture of the roof finial we made, compare to the real one (!?) here;
We permanently spliced the storm guys onto the rings, so you always know you have the right rope and you don’t get tempted into using the rope to tie down a trailer, and then lose it. (Thus speaks the voice of experience, sigh)
And lastly, here’s the cutting pattern. If you leave out the rectangular pieces between the poles, you could also make a single bell tent 4.2m high, with walls 2.1m high and a diameter of 5.4m at the base and 3.4m at the eave.
Looking at this cutting pattern now, I can see that it wasn’t very conservative with fabric. One of the things I usually really enjoy is seeing how little fabric I need.
We made the roof from 25m of 12oz canvas and the walls with 45m of 8oz canvas, that’s including the rectangular pieces that aren’t shown here.
