Does anyone have a file for a jig to you on a 3 fin BT55 tube they would like to share? I tried Thingiverse, could not find that size. Thanks.
 
Go to the scratchbuilt section and look on page two of the build named Sentinel upscale 2019.

or use this link

I downloaded a pdf of a fin alignment guide from payloadbay.com, printed it, copied it to a piece of

cardboard and using the wooden fin jig had what I think are spectacular results for fin alignment and

trueness when sighted down the body tube.

here's a link to the choices on payloadbay.com

You can enter the diameter manually along with other parameters and get what you want.

Good luck
 
I have used "Payload Bay" many times. It is great. But I wanted to try to print my own on my brand spanking new printer. Thanks.
 
I did find the one Charles linked. Have it downloaded, and will print it after this one is done. This printer thing is kind of like Lays potato chips :)
