I'm gonna start mine soon also. Not gonna use rivets unless it's to set the pan pieces in to weld, which is how I'm planning it. Hopefully my wirewelding will be without holes, but if not, there's a 2-part black alum. putty that dries super hard. We use it at work to fill in papercuts in mail sorters (USPS repair site) and let me tell you, it's GOOD STUFF! Need a grinder (or heavy disk paper) to smooth it. Just my 2C's. If I can start it soon, I'll post it, but it may be a month before I start.
