DanaEasterly,
This is what i did and its actually pretty simple. Hobbico sells a soldering iron for bout 8 bucks that has removable tips. Take the set screw out and remove the stock tip and go buy you some copper tubbing, i went the next size up from the smallest..can't reember the size off the tip of my head..cut you out about a 5 " piece. After that, lightly file the edge down to aid in piercing the paint on yoru model. Insert your copper tubing into the soldering gun, tighten the set screw and rivet away!!! I usually take a piece of strait tape such as masking tape..ect and make tick marks...this helps align the rivets up and space them out evenly. Hope this helps!
