What is the maximum allowable radius for each joint?
Picture the jet made from a contiguous piece of material if that helps.
Not at all; we were simply ignoring you. While I am as big a fan as anyone of möbius strips,today, Ghrey wrote: Was I some how unclear?

You saved yourself here, mate! I wish I could have you stay after class and write that out 100 times!GRIM wrote:THE PDF IS GOOD
LOL. Well... The answer to this question will decide my answer: have you already rolled the ejectors?GRIM wrote:I really dont want to make another big cone...
If you want to use the cone that you have, then kiss the ejectors goodbye: the whole point of RosscoIf "no", then my answer is "yes": you may use the concentric super cone.
If "yes", then my answer is "no": you must make a new spec. super cone.
Wow. The templates were sized for 0.8 mm, so you're way out there. Rossco will check to see whereGRIM wrote: One other not to drawing detail, is the thickness of the material, I purchased 1.5 mm,
when I got it home and started rolling, I measured it and found it to be 1.8 mm thick.
Have yet to see this one! IMDB rated it 7.6/10. The link... http://www.imdb.com/title/tt0119396/ .GRIM wrote:No kill Bill , but Jackie Brown might put in an appearance sometime.
Apologies, to both of you , The main reason for my folly was an ignorance on my part re, PDF ,milisavljevic wrote:Rossco wanted to reply here, but me thinks he needs to chill for a while longer. Maybe a day, or two.

We have to ask ourselves why we even bothered to draw the patterns if no one is going to use them.
NO I have not cut or rolled the ejectors , So I guess it will be a concentric "unadorned core" ,milisavljevic wrote:If "no", then my answer is "yes": you may use the concentric super cone.

that puts you wrt. internal diameters, and then I will model how this affects peformance. No worries!
That's cool. And at least you can get thrust readings independent of the ejectors. Obviously, it does notGRIM wrote:NO I have not cut or rolled the ejectors, So I guess it will be a concentric "unadorned core".
Cool!GRIM wrote:No worries there, I took into account the material thickness, the cones are all within spec...
