[Anonymous No.356017]

Im trying to make a prototype of kettle, so i need some metal spinning, they are asking for £100 for a simple semi sphere of 170mm diameter....

how could i go about making a aluminium semi sphere without the extensive costs ?

i dont have tooling either.

build a metal spinning lathe.
It could be super crude, metal spinning aint rocket science.

You'll need to do some math to figure it out though but it really shouldn't take more than a few hours and will cost less than $30.If a bunch of ten year olds can do it at summer camp, so can you.
