I'm going to try to post one pic on this post an the finished product on the other one. Maybe that'll work. Some of you know that I was looking for a finned something or another for a master cylinder reservoir. Well, Russian saved the day and found this old finned aluminum 6 volt coil. I busted out the top ceramic part with a hammer, then cut off the retaining ring. I then gutted it, cleaned it up, and rounded off the bottom fins. next I went to Otto's Machine and had them weld in the tube made from solid rod. I ground down the weld, made a cap on the drill press with a hole saw, and polished it up with emery cloth and the angle grinder with a 3M roloc disc. then I went after it with 80 and 120 grit sandpaper. I got a discount on a tap and tap handle, and tapped it out. I later decided to round the top part of the fins too...I thought I'd share some pics of my "recycled" aluminum. Now it's my reservoir. Thanks Russian!
