Help! I lost my Semroc Astro 1 a while back and just ordered parts for a new one and realized i cant find the fin template........ can some one help me out with a full size copy? Many thanks!

Hi Bill!

Scroll down to the bottom for the fin templates.
There isn't a 1" reference, but I believe the balsa would be 3" wide.

Hope this helps out -

Thanks so much Chris! Hope you are well and having fun!

Here is a scan of the full fin sheet with ruler from a Centuri kit. These are the earlier version of the fins with a 'flat' tip on the trailing tip of the fin. This was changed to a 'rounded' tip around '72 or so.
