Just messing around trying to figure out what this tunnel transition piece will look like. I think I am going to keep it simple and make something like this. Need to wrap this project up before I get stuck in sheet metal quicksand!!
Here is the front piece I need to make. I am pretty sure this is the ugliest stamped piece I have ever seen - anywhere ! The wrinkles even have wrinkles.
I probably can’t fabricate it from scratch with 2 x 4s and large hammers. I am thinking about having a local sheet metal shop roll the edge bead and then I can wrap it around some pipe or something.
Searching I found this nice piece from Bowler, they package and sell them as a kit but said I could get just the front piece in few weeks when the next next production is complete. That was nice of them to offer. I will probably just work my way through this on my own. But it is still a pretty nice piece and probably would have saved me some time.
