I am fine on electronics construction, but not having any engineering experience, I need advice on construction materials. Bear in mind that I only have basic handtools, including minidrill, hacksaw and the like. There are a number of items I want to be able to fabricate myself (from sheet materials where possible). I am not concerned about things lasting forever, ease of cutting/shaping and reasonable strength are more important. For example a future project is likely to be an arm.
An amazing list with prices for samples of the most amazing materials you can play around with. Enormous range. Some of the prices are a bit ridiculous and some items look suspiciously like a ripoff but if you sort the wheat from the chaff there are some interesting things here.
