Because I have so much free time (LOL) I would pay for more of my time for
working on MY projects.
I guess that is called responsibility and you just get more of it as you
get older, oh well.
It is a dream and they build Airbus and high performance sports cars with
this stuff. And the shit is
addictive working with it, we did all fins at once with DP on the
Avalanches.
Total overkill - but they are mil-spec and indestructible and I got to
learn to work with it and also
do some testing on Aluminum for next years project.

The applicator looks like you could implant teeth in an elephant with it!
But I didn't see a temp spec for the glue...I need to go to 3M to find it,
I'm sure. Otherwise, no sag sounds really good.
It sounds like there are at least multiple options out there. If Cotronics
doesn't have what it takes, I'd certainly look for a better option. Losing
even one fin will be a very bad day.

People never account for their time, and the amount of time you spend will
outdo any costs on materials you use.
Lets bill Marino or Atteberry out for $200/hr for cad/blue-prints and time
a variable. One hour of their time is worth more than the glue. moot point
so, it is all relative. The amount of time spent on those killer fins, I
wouldn't use anything other than the best out there and I would not want
detachment.
The best glue I have seen or used so far (besides Cotronics 4525) for
general Fiberglass and Aluminum (AL) AL-AL or AL-CF is the 3M DP420NS -
Deep Penetrating 420 No-Sag. This stuff is amazing. It is thixotropic when
you apply it! Yes, that's right, it comes out as Black toothpaste and can
be applied upside down. Claims 2hrs, but varies with temp and humidity
(seen 4 and always let dry overnight regardless). Scott Yow and I recently
did the Avalanches with it as well as some of my own bond testing for a
motor project with G-Man
The applicator gun is the best part - expensive, but is stronger than any
caulking gun (like you use for the West 610 Gel) and delivers and accurate
and perfect mix
to the wand. It is the ultimate delivery system.

Cotronics will not bond Al-Al. The peel strength is not there even if you
do the sanding while applicating to removed oxides.

Dude... That is fantastic. Cotronics epoxy for those fins? That casing's
gonna get hot, ya know? 🚀

For those of you who haven't seen my thread on Rocketry Forum here are
the pieces of my rocket.
Fins will be bonded directly to the motor case:

I'll be using the altimeter/camera bay that I built for my 75mm carbon
fiber M685 project last year (37,785'). I had to cut down a nose cone and
join a coupler to it because this project will truly be minimum diameter.

Wish me luck. It's going to be awesome one way or another. LOL!

Hello,
I'm looking for an M2245 reload for XPRS in September. I have a minimum
diameter project that I designed around this motor. Unfortunately it looks
like they aren't available from CTI and they are not sure when they will be
back in stock.
Anyone out there have one they'd be willing to sell to me?
Thanks,
