I propose to drill through each tree trunk in two separate places, the position of which would depend on it's size and weight. Large Eyebolts would then be put through the holes and an eye-nut put on the end. This would provide us with 4 hanging points per tree. To ensure that the tree remained vertical we would have to make sure that the position of the hanging points did not make it top heavy and cause it to tip.A drift would then be shackled to each eye and then shackled to the grid system. These could then be lx-taped to to the grid to stop them from slipping along the steels. | I propose to drill through each tree trunk in two separate places, the position of which would depend on it's size and weight.

Stagefright Instillation by Suspect Culture in connection with RSAMD TPA students Calum Willoughby, Kirsty Campbell and Louise Marr.
The Project
We were asked to be involved with Suspect Cultures Stagefright Instillation at The Centre for Contemporary Arts (CCA) in Glasgow. This installation involved an element of suspending between 20 - 30 Silver Birch trees (sourced from a sustainable forest) above the cafe area in the CCA. The cafe has no structure above it but is an open space climbing 2 levels to a glass roof. The cafe is in fact located between the two buildings that have been linked to make the CCA.
(INSERT PHOTO OF EMPTY CAFE SPACE)
We were restricted as to the infrastructure we could build because we could not damage or mark the buildings in any way. Any structure had to be completely self supporting in that respect.
Our Solutions
Number 1 - Calum Willoughby
What it is
Use Petzl Rigging plates [Approx £2] and coach screws [£2.79 for 10 {M10 x 90mm}]
put 2 at the base of the tree on opposite sides, and another 2 at the top of the trunk on the 3rd and 4th sides.
Cheap but not sure how safe this would be, bolting through might be easier.
POA for rig
2 different lengths of steel
at least four 'bars' needed on the grid to attach too
Costing
Very cheap steels need priced, [Approx £1 per meter]
Number 2- Kirsty Campbell
What it is
I propose to drill through each tree trunk in two separate places, the position of which would depend on it's size and weight. Large Eyebolts would then be put through the holes and an eye-nut put on the end. This would provide us with 4 hanging points per tree. To ensure that the tree remained vertical we would have to make sure that the position of the hanging points did not make it top heavy and cause it to tip.A drift would then be shackled to each eye and then shackled to the grid system. These could then be lx-taped to to the grid to stop them from slipping along the steels.

Costing
- Item- Eye bolts (Available from Flints.)
- Type- Drop forged collared long shank eye bolts.
- Size- M12, 178mm thread
- Price- £9.84 (each)
- Notes- These are expensive although they are safe to use with non-vertical loads.
- Item- Eye nuts
- Size- M12
- Price- £2.95 (Each)
Number 3 - Louise Marr
What it is

Costing
Number 4 - Steve Macluskie
What it is
Single Hanging Iron at the foot of the trunk. one single steel going up the trunk with a timber hitch
SEE LINK [1]
POA for rig
Haul tree up at Bar end of the space, clip on and pull out to position.
Costing
£5.80 per flying iron (unlipped) Plus bolts to go right through the trunk
