Mark, If your rollbar installation is so flexible you would be worried about cracking the windshield, then yours is way more flexible than it should be or any I've seen. Keep in mind its primary purpose is a "rollbar" which could be subjected to an 1800 # impact load and not collapse. I did a little study at our last Leeward Air Ranch Fly-In. I watched pilots getting in and out of RV8's and RV8A's. (We had 18 of them) Two of them had handles installed on the rollbar and of course used them.14 out of the remaining 16 of them put their hand on the windshield fairing at some point in the process of getting in or out. Certainly if you're young and agile you can do without it, but I wouldn't even consider building an 8 without one.

No welding involved. Theres now a guy selling them of the same design except his are made from Aluminum Tubing.
