Howdy All, I haven't posted in a while because I didn't think I was making enough progress. But, now that I'm entering the final phase, I certainly can't make that claim anymore.
But, first, I'd like to thank all of the previous posters for your ideas, support and encouragement.

Having no formal construction background I certainly wouldn't made it this far without your help.
That said, let's get down to some shop remodeling. First off, I had insulation added to the ceiling. I hired this part out just due to the enormity of the project. They first added 1x4 strips tot he purlins and then attached netting to the 1x4's. They then added cellulose insulation in between the netting and the ceiling and covered it with some foam insulation that is about 3/8" thick. The two sections on the right of this next pic show the final product while the section on the left show what I started with.

Here's a pic which shows, in the middle sections the 1x4 strips with the netting and the insulation added:

Once they completed that job I started on framing the walls myself. I started out by building the sections on the floor and then lifting them up and putting them into position. Notice I said, I started out that way but, after picking up the first 10' wide section, (which is 15' 3" tall), I figured out I didn't want to do
that anymore and began building sections which were 5' wide. On the left hand side of this next pic you'll see the first 10' section then a much lighter 5' one.

And then, several more sections:

But, by the end of the project I was securing the bottom plates to the floor and then just toenailing the studs into place. The bottom line is, either way the methods used made the walls rock solid. I doubled up the 2x4 studs for the section where the 3 horsepower Dust Gorilla is going to hang because it is some kind of
heavy. For most of the cross section strips I used #14 x 2 1/4" self drilling screws to attach to the metal strips (horizonital studs??) of the building. But, once again maybe going overboard, but I literally bolted the studs which will hold the Dust Gorilla.

and Hilti powder actuated nails to the floor. I also used the pink sill foam beneath the treated wood bottom plates.

I moved all of the outlets and the breaker boxes out so they would be flush with the tongue and groove panels once they were installed.

I didn't have a clue on how to do the ends but, the owner of the insulation company loaned out his 18 year old son to me. Don't let his age fool you, this kid had more knowledge, (including construction info) in his little finger than I have in my whole body. We got most of both ends done in 3 days and he had to move on to another job. It was more than enough to get me on the right track and I then finished them as well as the the rest of the sides. Here's a pic after the extra insulation was added.

I've now started on the final phase which is installing the tongue and groove 1x6"s and I'll try to post more pics of that as the ones I took didn't turn out too good.
