Pics of your DIY fin alignment tools?
I searched but didn't find any.

I use a pair of accurately calibrated eyeballs as my DIY alignment tools.
TLAR, SWAG, and KISS certified. If you need a definition of those acronyms, I can gladly provide. Just make sure to avoid SNAFU, FUBAR, and BOHICA.

Attach the printout to *corrugated* cardboard (I use double-sided tape) and cut out the unnecessary bits (notice the triangular cuts where the fin meets the body tube). HTH,

Rob-
I know you said “DIY” and what I’ll list below is a commercial product (and one I have never used, at that!), BUT, I have contemplated getting some of his guides for some time because they are fairly cheap and look very easy to use and look like they might work pretty well. Here’s the link: http://qualmanrocketry.com/Fin_Guides.html Now, if someone here HAS used these guides before, please chime in. Rob would probably like to know and I’d be interested also! Earl

Coincidentally, I just used a Qualman jig last night on my Kram fins.
They are my go to fin alignment tool. My Estes fin alignment guide is gathering dust.

For smaller rockets I use either the gray Estes Fin Alignment Guide or the yellow Estes Tube marking Guide has a little slot in it and rubber band it around the tube. Sometimes I get lazy and just print off a few of the old skool Centuri positioning guides.
https://www.towerhobbies.com/cgi-bi...AA EgItiPD_BwE https://www.acsupplyco.com/estes/es...rking_guide.htm Someone made me a few custom fin alignment guides from plywood for LOC 1.5" tubing and for Semroc Series 125 & Series 13 tubing for three fins. I have a LOT of scratch builds to complete in those sizes and since a couple of those projects are multi stage I wanted the fins straight. Also, like Jay I have used the rocketry tools at Payloadbay.com .... they have some pretty cool online tools there.
