http://www.macbeath.com/ is a good place for Padauk, Teak, & Purpleheart. I believe Berkeley is their main location. Call & find out when they get shipments(to get the primo pieces)
Welding rods can be found in any Home Depot, Orchard Supply store(got some there), or Loews.
There are a few avid gun builders on retrosub - you should join the yahoo group & hook up with some of the local builders.
Give me a call, we'll make it out one of these days
