Here’s a photo album giving a few more details on the circular tank I made for a Spinaway-built Hiawatha rowboat motor.

I hid the seam on the side panel under the filler neck casting. Cut a window for the fuel opening then stuck the filler neck ca sting over the window. I wasn’t 100% happy with the solder job I did, but I ain’t perfect, and it didn’t leak.
Hope this helps.
Best,

He's livin' in his own private Idaho..... I hope to go out quietly in my sleep, like my grand-dad did..... and not screaming, like the passengers in his car...
