No, you can't make methanol at home. It's a petroleum product. You can
by it at any place that sells racing fuel. You can use ethananol that
you distill yourself, but it has to be very, very dry, 99.9%. This is
difficult, but can be done.
Take a look at this site:

Lots of good info.
I plan on making some small batches this summer for my M35.
