Cherokee D Fin pdf?

[Wm Reid]

Hi gang,

I’m looking to scratch build a Cherokee D and I had a couple of questions.

1. Any place to find a pdf file of the fin with a ruler for scale.

2. Will a Cherokee E have the same size fin as the ‘D’?

Thanks,

Reid

Ktesh might have an un-adulterated Cherokee-D OpenRocket file and his fins for it should be spot-on as he's a bit ocd about correctness.
IIRC the Cherokee E fins are a slightly different shape than the Cherokee-D

1. I found that the Cherokee-D fin pattern on the JimZ Plans site print to exact size if you are careful to print "original size." It disappoints me when people go to the trouble of creating "plans" but don't include a scale of any sort, or worse, not include fin patterns at all.

2. I compared the Cherokee E and Cherokee D fins and I found them to be the same size. The pattern of the laser cut Cherokee E fins looks to me to be a copy of the original Estes Cherokee D fin pattern.

Now, according to John Boren, the Cherokee-E fins are based on the original drawing of the template.

Here's the rub... I remember measuring the fins from the latest version of the Estes Magician and they were about 1/32 inch smaller in all dimensions to the Cherokee-D that I built in the 80s, and still have. The Magician and the Cherokee-E use the same fins. I suspect that the current fins may have been drawn from the inside of the line and not the dimensions of the actual parts (which may have been made from the outside of the lines).

I bought a vintage unopened kit from eBay last year... But it is stuck in one of the boxes in Ohio, and I can't get it until Randy can get a price to ship them to me. He's slammed with moving his apartment and the eRockets. Once I get the kit I will be scanning everything with a good rulerf a unimpeachable sample of the original.

Yet for all practical purposes, negligible

BTW... eRockets sells a clone of the short version of the Cherokee-D, but it has a balsa nosecone.

Once again, thank you for the feedback.

Thanks again everyone!

It ought to be. Historians shouldn't be heedless of context.

Guys, please don't poke the krazy klingon. It could get ugly. In this ever changing world in which we live in I find his steadfast quest for absolute fidelity in all things model rocketry comforting.

Keepin it real samb...but I do very much appreciate his work and his talent for picking apart details.

I dug through my old fin patterns and found the 70s era Cherokee D. Not sure how it's done now, but then the fin was in two pieces, to fit the width of the balsa that came with kit. I don't recall the exact date and whether it was a "long tube" or "short tube", I know it was close to when the kit first came out...I scanned with a ruler so you can decide...

Neat!!!

Learned something new today... I've never seen that for a Cherokee-D. As far as I had known, they always had die cut fins. That is a piece of history right there. You don't happen to have the original instructions anymore would you? If you do, please share them.

Thanks for Sharing!

No, I didn't hang on to instructions unless they were for scale models back then.

Yes, the real must be kept. I’ve come to accept, if not personally embrace, K’tesh mania for the minuscule. He goes hard. He goes all day. You can’t stop him, you can only hope to contain him.

Oh we were all so young back then... If we only knew then what we know now.

Unfortunately I can only get down to the nearest .001"

Great pdf! Thanks!

JimZ has rocket plans for both the ‘short’ and the ‘long’ versions...they have a scan of the fins but no scale to go with them...this is great!

Thank you all,
