Need you ask?!

:bangpan:

Get building, already!

Oh, and who put that candle in the way of the build?????

BTW, this rocket is on my list of "things I'd like to get someday"

-Kevin

Getting started...

Step 1: MMT Assembly.

Here are the subassembly parts.

38mm Motor Tube.
2 Motor Retainer T-Bolts
Internal Launch Lug
2 large Centering Rings (6":38mm)
2 Small Centering Rings (3.9":38mm)
Cable Shock Cord Mount

op:Jumping on the subscribe wagon.....this is on my wish list also. op:

I'm in!!!

Sweet!

Greg

I'm in too. I would love to build one of these.

Count me in also. Been waitin' to see what this one was all about.

Thanks for the interest.

I'm going to build her close to stock. I'm going to add a little FG reinforcement at the forward transition.

Staying with the single 38mm engine. I've ordered a 38mm aeropack MRS, which would mean recessing the aft centering ring about 3/4" (this will allow the display F1 cluster plate to still fit). Not sure it's worth the change for the MRS...

Ill be watching also!
I WANT this kit, even thought Ill never be able to get it....

I am in! I am pretty jazzed about doing something scale. Not sure is I want to take on this big a project, but hey, we will see how yours goes! Good luck! John.

First epoxy has been laid... I can only go so far until the Aeropack MRS arrives...

I reversed the two main centering rings (I used the solid ring for the aft ring, as I do not intend on using the T-Nuts)... I will fill the holes in the now forward ring with dowel/epoxy when I do the fillets.

Next up... Parachute bulkhead...

That would be the wife! But she lets me stage my projects in her dining room... so candles in Simon Pearce Hurricanes and florals must be tolerated!


As an aside,... for any of you near Vermont... The Simon Pearce Glass Factory is worth a stop. It's in an old mill on the river,... powered by its own turbine in the falls. Amazing engineering, history, and beautiful! My kids love it too. The food is fantastic as well.

Centering rings are reversed and shockcord cable needs to go through holes in front centering rings. If photo shows glued assembly.

I've had one of these squirreled away in my closet for a VERY long time! Lets just say over a hundred dollars ago, I bought one at a launch at Bong State Rec area (honestly, I don't remember the year. I think it was 2000 or 2001). It was the most I'd ever spent on a kit up till that time. I agonized most of the day before finally deciding to pull the trigger. I was still married (happily, or so I thought) at the time, so she actually encouraged me to get the kit. Oh well, life goes on and I still have this kit hiding in my closet, waiting patiently for me to grow up and finally build it. I'm gonna be 46 this October, so apparently, I'm not growed up enough yet :wink:

Yes. Explained why in my posts above...

Correct, but I'm not running the cable through the holes until after I do the fillets. Didn't want it to get all buggered up with epoxy.

I might have missed something, but i can't help wondering what the large holes in the two smaller rings are for. They look to be about the same size as the launch lug, but are too close to the tube to serve that purpose. Surely they aren't meant to reduce weight. What are they for?

You pop the popcorn, I'll get the moist towelets.

The cable that the recovery system gets attached to is run up through those.

Correct. I'll run the cable through them once I add the epoxy fillets (easier to keep the cable clear without it run through the holes).

The Parachute Bulkhead (serves to keep 'chutes forward during flight).

And installed in the 3.9" body tube (inner body tube/Stage-III section).

Up next... fill and sand the spirals on the 6" Body Tube and the forward section of the 3.9" tube...

Definately interested in this one too. Keep up the awesome photo work!

Thanks for the interest and kind comments.

I'll shoot detail shots on request if anyone has a particular interest.

Got the hard part done. Included a couple items in the pic to provide scale.

The main body tube is 6" x 37". The 3.9" body tube is 34".

Back to work tomorrow.

I'm enjoying this thread even though I'm strictly a LPR guy so far. I do love me a good Saturn V build thread though!

Someone rattle this guy's cage and tell him to post more of the build. It's been two days.

Well,... since you asked...

I have added the filets to the top 3 rings of the MMT Assembly. The 'chute cable has now been routed through the guide holes. The two T-Nut holes have been filled with dowel, epoxied in place, and covered with fiberglass to insure a good seal.

I can't secure the aft centering ring until I receive the aeropack MRS... Hopefully will arrive this week.
