George,
When I get impatient and want to see what a structure is going to look like I will prop up the walls using the lines as a guide.

For cutting strips of masking tape I will stick it down on the mat and align my straightedge to the tick marks.

One feature I really like about these mats is that I can feel when I have cut all the way through material because the drag on the knife is different. Poster or mat board work but you don't get that same contrast.

Here's a couple of photos showing my progress on the roof:





A few more trusses to install, then more of the 6 by 6" rafters to tie everything together.

The side walls are just put into place; they will come out when I install the machines.

That is looking so sharp!!! How does the roof separate from the rest of the structure?

Bob,



It's pretty flimsy at this point but there's a long way to go.

It'll be a shame to cover up all that work with a roof!

Mike, when you are done with the crew of LP doing that roof framing, I could use them.

That last picture helps a lot to understand the construction process, particularly how you handled the belt drive installation (which is very fussy...) Is that "layer" with the pulleys on it also removable?

Oh! OK. That's working fine. I'm sure that by the time you add the sub-roofing the flimsiness will disappear. Like the treasure on Oak Island.

Bill, Thank you. I sure hope it all works.

Mike, The model will probably spend much of its time with the roof removed.

Bruce, at the rate which my crew works you would not want to hire them.

Dave, the layer with the pulleys is glued to the end walls.

Philip, thank you.

Bob, there are a couple more layers of wood to go. The roof will be pretty solid at that point. Strength through numbers.

I seem to be moving faster than normal. For instance, the one layer of rafters is complete for now:



Here's what things look like with roof and walls out of the way:



And here's the roof assembly so far:



This evening I started cutting 2" by 8" boards for the next step.

Again, thank you for all the encouraging words.

Mike

Mike, it's almost like a layered cake, filled with belt driven machinery.
Nice bit of work pulling all of those roof pieces together.

Greg,

Thank you.

Some cakes have files inside, mine have machinery. Eventually.

Mike

Mike, how are you holding the walls in place? Friction fit? I've been thinking about tiny magnets for the walls in my Wichendon Machine and the roof on my CM roundhouse. The one problem I've had with the latter is gluing the magnets in place, so far the epoxy hasn't held them and removing the roof often leaves the magnets behind. (magnet clamp is stronger than glue strength.)

Dave,

Are you using two magnets or one and a piece of steel? I would use two magnets plus a small strip of metal, the thinner the better, to hold the roof down. Use some "feeler" stock metal that's about .002" or .003" thick sandwiched between two pieces of wood so you don't see it.

If you can't picture this I'll see if I can get a picture of a mock up by tonight.
