In any case, I found some time to layout a cardboard template for the shutter frame. I needed about 2 3/4" to clear the curvature of the dome in the center. I made the template 4" high to accomodate the inner frame for the lower shutter, and I hope to fit an outer shutter over the entire frame then (at least that's the 2 minute plan).

I did manage to get the shutter framing at least cut. I'll be working toward mounting these up hopefully this week.
It's another busy week. The Gemini II kit shows up this Thursday, so I'll be playing with that too!
Should have some new pics of progress sometime shortly.

This week, I've been working on mocking up the wood shutter framing with the dome. It sounds easy, but proving more difficult. Reason being is that I made a 30 degree radius cut on the inside cut of framing to accomodate the dome. Since I cut it with a scroll saw - it's uneven and left gaps between the dome and wood frame. Time to get the belt sander out and fit it as best I can, then check for squareness. Compounding this, is the fact that I have several pieces. Will need to get all pieces together, then fit them to the dome. Hopefully I can get this behind me this Sunday, as well as get the base drug back in the garage!
Now if only a good warm, clear night to try out the GII!

I had the framing for the shutter cut and mounted on the dome over the past week, and as you can see it's still a mock-up until I have the shutter completed and am happy with the mechanism as a whole.

I'm also reconsidering the telescope design of the shutter (one piece sliding into the other. It would be much less trouble to keep the upper half sliding, while the lower half hinges out (now I see why there are commercial designs like this).

Coming along pretty good!
I also looked at steel doorways... Looks like my most inexpensive option is a $116 steel door. It'd be 30 inches wide and I'll need to cut it down to fit the body. If anyone has a cheaper recommendation, please let me know.
At the moment costs are as follows:
Fiberglass tank: $200.00
Skates (wheel set): $40.00
3/4 inch Birch Ply: $90.00
1/4 inch ply (for shutter): $20.00
4 Casters (for shutter): $10.00

This is the last of the photos that are going to be taken with my iPhone!!! Time to break out the "old" technology (the digital camera). Both Google Chrome and MS Internet Explorer show my photos right-side-up, but iPad & iPhone are upside down... Many appologies...
