Hi all

Recent research by Google indicates that dome-hype in Australia has increased by around 25% since the beginning of the dome home website.

This is a key hypothesis in the current draft business case for a modular truncated icosahedral tent business.

It was d-day for the dome after successfully completing 5 hexagons. The top semihemisphere was ready to be assembled.

Figure 1: laying out the completed hexagons

There were a few problems encountered.

• The hexagons, when resting in natural position, were a few degrees off and so couldn’t be bolted together. We had to loosen bolts & “fudge” them together – although, there is not any significant warping in the frame once the bolts are tightened
• The screws sticking out of the joints prevented the hexagons from fitting together
• The bolts were compressing the timber when being tightened – this was resolved using washers

Au revoir

With the year coming to an end – an update on the DOME home status for 2018, in picture form:

Figure 1: The timber was confirmed to be straight

Figure 2: 16mm pocket holes were drilled using 16mm countersink bit & radial arm drill press. 2- screws per connection will be used. Buildex 14-10 x 100mm timber screws were pre-drilled.

Figure 3: Sika Pro was applied to the joints prior to screw fixing

Figure 4: 3- two hexagon sides are connected first

Figure 5: The 3- two side sets are connected to form a hexagon module. The hexagon corner jig is seen in this picture

Figure 6: Gettin jiggy

Figure 7: 4 hexagon modules are complete. The design distance across the diagonals is 1850mm. The as-built hexagon modules range from 1847mm to 1855mm across the diagonals – this error seems tolerable.

Hi all

The protracted lull in website activity is noted.

To resolve this, the group name will be changed to Roaming Discretized Ornamental Modular Eco-friendly (DOME) Home.

Regards

 

Weekend 20/21

 

Equipment:

 

1. i)    Drop-saw
2. ii)   Measuring Tape

iii)  Straight edge (more than 1m if someone has something suitable)

1. iv)   Pencils
2. v)    Drill press
3. vi)   Drill bits (depends on what size bolts we are using)

vii)  Clamps

viii) Safety Goggles!

 

Stuff to complete:

 

1. i) Cut Pieces

    – Length: 1m (~2.7m height) (maybe a little shorter depending on lengths of timber from bunnings)

    – Angles: http://polyhedramath.com/finding-the-angles-of-the-truncated-icosahedron/

    – Amount: 60 hexagon sides, 30 pentagon sides

 

1. ii) Drill Bolts’ Holes

    – Need to ensure that:

1. a) all hexagon holes are identical
2. b) all pentagon holes are identical
3. c) all hexagon holes align back to back
4. d) all hexagon holes align with pentagon holes back to back

 

    – Possible Method (3 holes):

1. a) start with one hexagon piece
2. b) use 3 holes
3. c) drill centre hole by intersecting the diagonals so it is half of the width and height
4. d) measure other two holes 200mm on either side of centre hole. *Important: must guaruntee to be half of the height as well*
5. e) use this piece as a template for every other hexagon piece and for the pentagon holes

 

What do you talk about in blog posts.
Drill presses?
It is much heavier and less useful than I anticipated.

Them bitches askin why I  spend my weekend building domes
I tell them I was born with geodesic chromosomes
