Hi Jason,
The 8" is still a work in progress and is a rather crude one as it is made from wood, but I'll be completing it in 2 weeks and will post some pics.
For the 12", I'm leaning toward aluminium as there is potential for reducing weight and is easily machinable.
One such design was this, but featured a very long OTA.

I'm working toward a portable design for the 12".
I was told there are different grades of aluminium with different tensile properties, so will need to look that up.
I'm also leaning toward friction drives or timing belts rather than worms. still contemplating a few combinations.
I have the electronics with autoguiding and wireless control sorted out though. All home built. I'm adapting what I learnt with the 8" into the 12".
