Having played about with various models on Sketchup for different styles of tent I eventually decided on a double wall dome.as on paper it a dome gives a good volume without requiring excessive ammounts of fabric.
The design is essentially a 1.5 person tent that being me and the dog or another person at a push.
feel free to suggest changes to any points that may improve the design.
The plan is to make it out of cuben using25g/m2 cuben for the fly with a covered mesh vent at the very top fly will go down to or be very close to ground level but will be possible to slide the fly up the poles a few inches to allow venting. 48g/m2 cuben for the bathtub groundsheet as it has to resist the wear of the dogs paws. Inner will most likely be M50.with mesh vents at the top.
The poles will be attached by clips and shock cord. the shock cord will run through the seams to form the inner tent attachment points the idea being that this will help reduce the stress on the cuben. corner guys will attach via the pole shock cord. Guy points will be attached to the middle of the side panels to reduce the ammount of unsupported fabric.
An educated guess towards total weight based upon material weights for all componants and approx sizes required puts it at no more than 800g.
Also decided to model a much bigger dome tent a 2.5 person this time with a porch on either end.
This one is a 4 pole design and bigger, and the inner sits in the middle but appart from these differences they are not that different . Poles in both tents are the same length too. Estimated weight for this one is 1.2kg. but for now it's the "solo" model that I aim to work on when the opertunity arrises.
