Canted, non-square centering rings have always bothered me. When building a high-power rocket, they can make it harder to fit the motor mount into the airframe smoothly, as well as make through-the-wall fin mounting a problem. I just used my Center Ring Standoff the first time last night and it made it a breeze to get the centering ring square to the motor mount tube. I'll definitely be getting the rest of the set, soon!
Roy has great communication if there are any questions andlightning fast shipping! This jig is perfect for all projects sizes from low power models to high power cert flights and is robustly constructed to probably out last most of the rockets built with it
Easiest to use jig I've ever had the pleasure of trying out. Really impressed by how easily it allowed me to get my fins nice and straight - once the jig was set up, I spent more time making sure my epoxy was thoroughly mixed than I did setting the fin.
Thanks!
