Gents,
As part of the new project, I need a dimension that isn't on any blueprint please, from a stock F1 Rocket with a Lycoming IO-540, Indy mount, and a constant speed prop.
What I need is the exact distance from the face of the firewall to the aft edge of the spinner. Not the firewall flange, which varies, but the face. And please don't measure the curved length along the top of the cowling. Actually, I could use that dimension too, as a back up reference, but it'll complicate the set up if I don't have the requested dimension also.
So, the next time you've got the top cowl off of your Rocket, please grab a 4' drywall T-square, or other decent straight edge, and write down the dimension.
I'm building a new engine mount jig and having this number is critical to making the new mount "swappable" with an existing mount.
THANKS in advance!
