Thanks Wayne & cheers for pics of your cockpit, looks amazing!.
One thing I hadn't thought of till today & sort of hit me while drawing out some dims, is I hadn't factored in the plating & Koolshade taking up some of the diameter & also the Panther strips not being pulled absolutely 'tight' around the tube. Funny enough 5 1/2" tube could still be a go!. I'll do a few more measures tommorow, but 6" seems out of the equation & 5 3/4 is a push!.
A couple of things I noticed with your cockpit Wayne:
You seem to have the 'newer' Koolshade with less louvres per inch. Where the Koolshade covers each 1/2" hole, yours has 8 louvres, while the actual prop & my Koolshade has 12 louvres over each hole. Counting the vintage Koolshade louvres wouldn't give a good approximation IMO.
Your Panther strips aren't in the orientation to match the actual prop, they look great, but the rivets/breaks etc... don't quite match. I'm still convinced these strips give the right tube size & donor part orientation. These strips are a nightmare to work out though, a few times Iv'e had them the wrong way around so as giving a false dim on either the top or bottom. One point of reference with the fender strip though, is that one rivet is in exactly the half way mark, so that's a start & a ref I keep going back too.
If it turns out my 5 1/2" tube is ok I'll be a happy chappie, just needs a bit more time to be sure.
