Problematic legs
First I cut some 1
3/4" tubes (12 X) from a length of plumbers waste pipe, once cut the raw edges
had to be sanded, I then covered each section with aluminium ducting
tape (this part was ok)
Next I wanted to make foam spacer joining pieces to go between the tube
sections so I cut all the disc's from a 10mmm foam exercise
mat (all 40 of them) this I intended to cover with black tape but it had the desired
effect of either distorting the disc shapes, not sitting flat or coming
unstuck
(this stage didn't go well and was scraped).
Rethink
I decided to make a mould and cast the joints from black silicon (this is
working very well)
the first step was making the joint out of sculpy, once baked and cool I made
a central line through where the joint will be then I made a two part mould from fine
casting plaster,
moulding with the silicon has proved straight forward

Robot body
I have had to bolt the hips to the legs (for constructional reasons) and the hip section to the body to make the waist swivel.shoulder caps have been made from ping pong balls
and dome head from empty pop bottle (doing my bit for recycling)
see image below.
