When I do this type of thing I put fillets inside the tube also. You have good access so easy to put them in before you install the rings. I would probably even use Titebond II wood glue for the internal fillets.
Agreed. I once had to pull a lady's fingers out of a glove because the drill tore them right off. They could not be reattached because her full tendons were attached to the fingers. Be careful.
Much more complex than it has to be. Relies too much on wood working skills and specialty tools. Plus this would be difficult to repair when a fins breaks. I will stick to three centering rings with fin tabs that glue to the motor tube.
This is actually a pretty old video and I have changed my fin installation since then. Newer system is similar in design but simpler. I don't use the motor tube design though. Reason I don't do that is because then I would have to find cardboard tubes that fit all my motor designs perfectly.

Certainly not a bad idea. The more bonding, the better.
Very helpful thanks!!
Don't use gloves unless your okay with having your hands ripped off

How bout clamping a fence guide onna drill press ? Gives a better longitudinal guide
This type of cutting bit will always try to grab and spin the cardboard, but you are correct, a fence guide can be helpful.
I thought about rubber banding a piece of angle aluminum on the tube to act as a guide. But maybe that bit would cut in to it
Man..... You love that MDF.....You must work for that company. :)
It's great stuff. I like it much better than wood because it doesn't have a grain. So no splintering or splitting.

@@rotaryrocketry updated video please lol....
I like 6
Same thing I used to do when I was younger. Your fin shape is nearly the same too. Yours is a bigger version than mine though. Good to go.
The fins will never pop off this rocket!
That's the dream :)
They won't pop off but they can break which makes for a difficult repair.
