Dan,

Mine is like the prototype, flush on the sides and protruding head on the bottom. Bob's has protruding rivets on the entire plane.

Might be leaning more to the CCP. I just can't get a picture in my mind of how it will look with part BSC and part CCP.

I wonder what Paul and Bob are choosing? I also wonder about making this depression on two sides of the tube and how that affects the strength, if at all.

I don't have to decide now as this will not be happening for at least 6 months.

At times, I think that the better decision would have been made back in February last year, to go all protruded. A little knowledge goes a long way.

Dan and I found that it worked best with a 100 degree die instead of the 120 degree die when we did testing on a section of tubing. That is what I did my fuselage with, and as mentioned, it is a depression not a dimple that is formed.

Dan,

I'm guessing SPA would be most happy to sell you another cage so you could do dimple testing. Or you could just buy a one foot piece of 1/2 x 1/2 x .035 and test on that. To get a good sharp dimple normally requires both a male and female die. What you need to do is figure a way to get the female die inside the tube.

Tony

Would it be better if the cage were dimpled with the DIENQ? I would do a test, but I only have one cage.

Hi Jim,

Thanks!

Of course you can build a Panther! There are plenty of first time builders already doing it. It only takes three things: perseverance, perseverance, and perseverance. With enough of that, everything else will fall into place.

Tony

Tony,

Just wanted to say how much I've enjoyed browsing through your Panther build pictorial log. It's helping boost my confidence that I CAN build this airplane.

Thanks!

The dimples in the tube are obviously not going to be near as crisp as the skin. It certainly works, but as I explained to Dan on the phone yesterday,I think most builders will skip dimpling the forward fuse and use CCP-42s where the skin meets the tubes. It wont be very noticeable as the wing covers the lower portion ,and a lot is "going on" in this area so it will look fine. to each his own

Have a look at fuselage photos 168-170. I wasn't able to get a nice crisp dimple using just a male die.
