Today was a good day. After many days of second guessing myself, laying down the cut line, erasing the cut line, laying down the tape, and pulling up the tape, I finally got my guts up and now I find myself on the other side of THE BIG CUT. Somebody on here said that they were told to "grow a pair" and just cut it. Well, those words also got me through this stressful time...wise words indeed. Actually, I was MORE than ready to do the cut today. I guess I was just tired of thinking about it.
So, the temperature was right. The outside temperature was in the mid to high 80s. Check out the greenhouse effect inside the bubble:
This made for a very happy piece of Plexi.
So I marked the line with a Sharpie, backed it up with yellow tape, then placed blue tape on either side of it. I marked the line about 1/8" forward of the forward bow:
I got myself a 4X8 piece of that particle board type of stuff they use on roofs. Unfortunately, the bubble is very near or beyond 4 feet in width. That is why I installed the "goal posts" you see. I put the sheet on my low saw horses which supported my fuselage for years. It made for a very comfortable height. You can also see my tool of choice for the cut, the Harbor Freight oscillating cutter:
I notched the board so that I would have clearance for the saw:
Let the cutting begin:
And some videos of the job:

I worked slow and made three to four passes before I plunged through. Fini:
This was pretty anti-climatic. It came out pretty well and I'm relieved that there were no cracks. I wasn't pleased at first with the consistency between the distance of the cut to the forward bow but I've found that there is a bit of adjustment in the bubble/frame relationship even with the handle hole drilled. I did manage somehow to put a couple of small stress concentrators at the cut but they were easily sanded out. I plan to Sika the canopy and I will wait to make any further adjustments to the cut via sanding until after I've glued it all up.
So get out there and grow a pair!!! WHEW, I'm glad that's over with!
