I did a few minutes of research on Plexus products. Sounds good to me. I found a web site called the Glue Guru that sells it.Seems like Ive seen it locally somewhere before.I do know that I can get Sem, 3m , or Duramix products locally though. I think Ill be patient and order what you guys are recommending.

The booster stage of this rocket will have 4 airframes sitting along side each other to make up more of a square shaped airframe that holds 4 motors. (Ill put a picture up).In the center there will be enough room to put a 2" tube in between them as a backing plate for something to attach to. I’m hoping this Plexus product will be the right product to attach these also. I guess the plan would be to attach with the plexus product and then do a fillet with an epoxy product.
Thanks guys,
Terry

You probably mistyped and are referring to MA310. this is a 1:1 ratio glue, which is available in 50ml cartridges (the neccesary glue gun is not so expensive) and in 400 ml cartridges (with more expensive gun).

I believe you guys in the USA are lucky, and also have it available in a 250ml cartridge, which fits a normal 1 component standard glue gun, available everywhere. (in Europe these cartridges are not available unfortunately)

I might be lol im not back in my shop till weds so i will check its number then. You may well be right! maybe i was getting my numbers confused with 3m dp410 which is a good structural epoxy that i use sometimes, much more expensive than the plexus and takes several hours to cure unlike the plexus which is done in about half hour.

Not quite sure what was going through my head when i wrote this! the plexus glue that i use is ma310 and the 3m is dp490.

Thought I would post a picture of the fin set completed and on the airframe.
Thanks again everyone for the help.

Looks awesome Terry. When is or was it’s first flight?

#103

Looks great, well done.

Is the construction as you had planned, and within weight limits? Or did you make adjustments on the fly which brought improvements?

#104

for the WIN!!!

#105

Those look sweet!!!

#106

Nice job! Keep up the good work!

#107

Thanks guys .
Once I got one infusion to work correctly I just kept knocking them off. There were four fins , so there were 8 different infusions I had to do. This project gave me some good pratice.

The rocket came out pretty much as planned other than were I tried to experiment with the checkerboard pattern carbon.

It will be a while before this fly’s.I still have to build the sustainer and save up some cash. Im thinking sometime in 2012.

#108

Since you guys are doing such a great job of patting me on the back I might as well post a couple more pics.
Seriously, thanks again everyone for helping.

And Canyon , Herman, the photography advise paid off too.

#109

Very well done. What altitudes can you expect from such rockets?

#110

If I can ask how much does a motor for a rocket this size cost? By the way I love your plastic wrap trick for keeping your fabric clean.

#111

Well done mate! I found out my wife’s co-worker’s husband is into high-power rocketry, so I might ask you some stuff later. :slight_smile: I love the melding in the second pic!

#112

Sorry , haven’t checked back in a while.
I’m hoping to reach the waiver at Blackrock (100,000ft). I haven’t got to the point where I can do any accurate simulations yet. Ill have a better idea how high it will go once I can run these sims.

Motors this size can run over $1,000 each. And it holds four motors in the booster. The sustainer will hold one motor. But I plan to use a homemade brew propellant which should be a fraction of the cost.

100.000 ft, that is 33 km, or some 20 miles???

That is more than I expected… If you do that over here, you have a problem. Too crowded airspace. How to get the unit back? I guess it can easily land miles away from where you started.

#114

People come from all over the world to fly at the Blackrock Desert.
Its a dried up Lake bed that is about 70miles x 70 miles of wide open flat space.
I have to take a 3000 mile trip to get there. Ive only been there once but hope to get back for 2112 launch.

The rocket has a GPs unit in it. When it lands I take the last coordinate and plug it in my car GPS. Just drive right to it.

#115

I found your next project tbone! The X-51 Waverider :stuck_out_tongue:

#116

That things scary looking.
