Not necessarily a Todd's question but a general canopy drilling question. I understand the theory behind ensuring the holes and hole edges are dressed smooth. My question is, what about flame polishing? I am still a very long way away from working with the canopy but just curious if there is a specific reason for not doing it? I am here to learn.

Actually, I think an important part of drilling the plexi very, very slow (slow pressure, not necessarily rpm) is the fact that the drill bit clearly heats up enough to ever so slightly melt the edges of the hole by the time it pops out the other side. You can see it under magnification. That is about as far as I would be willing to go with the concept of "flame polishing"  .

Sika flex it, no holes required. No holes no rivets no rivets no cracks. Last I heard this was Todd's recommendation also.

There's an article about it in "27 Years of the RVator" that strongly recommends not to do it.

Difference in shape? Todds vs standard
Can anyone tell me if the Todd's RV-8 canopy is the same, or a different shape than a standard canopy. I am having Bruce's make me a cover and they have never heard of a Todd's and asked me to measure it for them.

I saw photo posted in another thread not long ago that I think shows the two different canopies. I'm not familiar with the airplanes but I believe the left is a factory canopy and the plane on the right is a Todd's. Maybe someone will come along that can confirm this.

local canopy to measure
I have a Todd's canopy on my -8 -- still in the garage at home, not far from Bruce in Sunnyvale. At some point I'll be buying one of his covers for my -8 (already have one for my bonanza).
The shape is different. In the past they've come out to local airports to measure specific airplanes. If they'd like a local example to measure let me know.

Thanks guys! That's what I had heard, and the photo shows that the Todds is more of a tear drop shape than the bubble shape. I'll mention you offer to him Greg. Is the canopy in place on your project?

I've got a Todd's canopy on my 8A and my Bruce's cover fits just fine. 335hours on the Hobbs.
