Materials
Here are a few links to where one can find certain materials for building that homebuilt rig. Most items like: Aluminum profiles, bearings, tube, steel, light alloids, alluminum bolts etc. can be found on some of these sites. So take a look and see if there's something that meets your approval. The links on this page were provided from readers on the forum. My thanks to them for sending them in. Will be adding more when new links are found.

Aircraft Spruce
This site sells aircraft supplies and they carry Alodine,
a pre-painting agent that allows paint to stick to aluminium.
It's not anodizing, but it's an inexpenssive alternative to it
and can give great results.
McMaster-Carr
A great site for all of your building needs.
They practically have everything you will need.
Highly Reccommended!!!
