I'm working on a design that uses a foil lined motor tube (24mm). The design doesn't have an engine hook. So, how should I glue the standard Estes/Semroc type AR-2050 centering ring/thrust ring inside so that it'll hold up to the stresses of being launched?

I've got an idea to drill holes, then pinning it in place using a toothpick, or a paperclip.

Feedback appreciated!

Holes + pins sounds pretty good.

With or without, I'd sand the tube at that location & use epoxy.

I contacted Randy Boadway (eRockets), the seller of the foil lined tube, and had this exchange with him.

RB: Wood glue works fine.

Me: I've got white, and epoxy. I was thinking of drilling and pinning it after gluing it in with epoxy.

RB: Not necessary, white glue will hold. Don't damage the foil on installation. It will last a long time.​
So, now we have it. I've been told that wood glue or white glue will do well, and not to damage the foil.

Thanks for the replies all!

Helps protect the tube from the ejection charge
