Same with classic cars. You can't expect to get your hours back out of the
vehicle if you intend to sell it. It's a labor of love.

Hi Chris,
You know, that's how it goes with rockets and projects in general, but
you can't say you didn't want to spend the time. Off list I gave James an
example. I'll repeat it here.
I like to make things from wood. I'm almost finished with a round front
hall table. I've got about 40 hours into it. At my regular billing rate, that
table is worth about 4 grand. But it's not really worth 4 grand. My time
might have been, but if no one will buy it at $4K, it's just not worth it.
It's a labor of love. It's the building that's the joy. Honestly, I've got
about $70 in materials into this table. I might be able to sell it for
$200...but my wife wants it. To her, it's priceless. Just like any of my
rockets were to me (even when I had to dig them out of the dirt!)
So all that time you spent was for yourself, and unless you're in the
habit of billing yourself, it will never be worth what it cost to build it in
time and materials to anyone but you, and those around you that know.
But... I know what it takes, and I appreciate the effort. So will
everyone that sees it fly.

Yes, there is a ton of time invested in a project like this one.
I spent at least 12 hours designing and building up the CAM files for the
fins. There's 12 hours of machine time in those 4 fins. That doesn't include
the 3 that I scrapped or the time to build the fixtures. The nose cone was
also a major time investment I think I spent about 20 hours designing it and
8-10 machining the parts. Then of course there's all of the time I spent
thinking about problems that came up.

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.

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,
