I've made quite a few home made fin marking guides after some the kit supplied guides didn't fit. Four fin guides are easy, wrap and fold into quarters. Three fin guides are another story.
A email from Mark reminded me of a technique I used years ago in the print shop when I set up three fold brochures.
Hi Chris,
Attached please find a simple method of making a custom Three Fin Template in JPEG format. I created this diagram myself just minutes ago. It's pretty self explanatory.
This is a response to:
Not a folding method, but just as easy. Please share at the above page.
Best regards,
Mark (aka ScouterMark)
Here's the drawing Mark put together:
Wrap paper around the body tube and mark the overlap.
Slant a ruler so that a measure (here 9") is divided by three.
Mark in two different locations, once at the top and bottom.
Connect the lines.
Wrap and mark!
I would normally just use one of the various marking guide generators (probably OpenRocket), but I have to say this is a clever solution. Would work for any number of fins. Cool.
ReplyDeleteI have to give props to Roger and Payloadbay, but this would work nicely if one of the kids was on the computer when I needed a template.
ReplyDeleteThanks for sharing Chris !
