Looks good, Buster. I started machining at that age but didn't realize I wanted my own shop, until a few years ago.
My shop is also a Quonset hut. The shape is a little different. My walls are vertical and then round up to a triangle roof with a round peak.
Also, the tar on your roof was to stop the leaks, I guess???? Someone put it on years ago. Do you still have a any leaks??? They are a booger to stop.
The instructions with my building and the different things I have read all say it is real hard to put in a side door and not have it leak. If you want I can scan and e-mail you some of the stuff that came with my building that tells about sealing and trimming the side doors. They all recommend putting any doors in the ends, and not the arches.
That entrance way would make a good compressor room, with an inside access door.
I am sorry to hear about your Dad.
Glad to see another quonset hut on here.
Keep us posted on the work. I may steal a few ideas from you.
