Bigger Deuce

[Rocketjunkie]

Got a second fin carved and fitted today.

I got the other two fins fitted today.

 

[CarVac]

That is... tremendous.

Hey Tom, you gonna have this one ready for Freedom Launch? Or one or the ROSCO's? I'd love to get a vid of this one.

 

[JStitz]

Tom..I LOVE those fins! I sure hope there are several Video and Digital still cameras for the first flight.
I cant wait to slow mo this canted 98mm Fun..:y:op:

This is why we enjoy TRF!

Planning on April Orangeburg. Motors will be M1100's. If I make the March launch and the rocket is ready, motors would be M1419's. Both motors have almost identical performance.

Onboard between the motors and handheld video. No stills unless others take them

 

[Rocketjunkie]

More progress.
Small nails are used to hold the fin from moving as the epoxy cures.
Then the fins are tacked on one at a time with 5 minute epoxy.

 

[Rocketjunkie]

All joints are then filleted with chopped glass reinforced 20 minute epoxy.
This process will take a while

Tom
This is looking good. I look forward to seeing more as it progresses.

I've been waiting for this since you asked where to get 9" components :wink:


This should be awesome! Watching intently!

I finally got all the joints filleted. Next, some 7.5 oz cloth is used to add additional strength to the joints.

This completes the fin can/motor mount assembly. Note the G12 motor tubes. These will take the entire impact on landing so they are the only glass tubes in the project. This unit weighs about 35 lb.

 

[Rocketjunkie]

Next, i got out my old copy of TurboCAD (V3) and modeled the intersecting cylinders of the airframe and motor tube. I took the intersection and printed the result. Using a copier, I scaled it to the motor tube size and cut it out. The result is a template for cutting the airframe.

 

[Coop]

Very slick. I wondered how you were going to do that.


Later!

[Rocketjunkie]

I got a little done today. I made a marking guide and marked the fin and motor locations.
I then trimmed the end off the tube and extended the guide lines.

 

[Eric1]

I hope I can make the first flight. You are doing great Bro.

I just ran across this thread. As I read through it, I kept thinking to myself "Holy crap!" over and over. This is going to be magnificent!

 

[Rocketjunkie]

Got some more work done today. However, my Dremel is on it's last legs, gonna have to buy another one.
Initial cutouts of the body tube
Then fit, sand, fit, sand, etc, until it fits.
Almost there

 

[webtech]

:y: did i read that right .. two M motors?!?

I haven't seen an name for this rocket yet...

I would call it M&M for two Ms
just try not to get sued

YOU DID ALL THAT WITH A DREMEL?! :y:

Wow, you have more patience that I. I think I would have whipped out a sabre saw or something of that nature. Heck, I might even be tempted to hack all that out with a circular saw.

Looking good!!!

 

[Rocketjunkie]

:y: did i read that right .. two M motors?!?

I haven't seen an name for this rocket yet...

Planned maiden flight will be on 98/7680 motors, either M1419 if NAR launch, M1100 if EX motors allowed
It will be Deuce 98 on flight cards, to distinguish it from my Deuce 54 mm.

 

[JStitz]

TOM BINFORD!! I didn't know this was you till that last pic!
This should be named "Motor Eater squared!"
I remember jumping in your vehicle at Orangeburg and chasing a ME almost to the convenience store! (now a strip mall of sorts as others have reported) ..I'll be back soon brother.
Those fins should have been a dead give away...

 

[DavieRockets]

Gorgeous build!

I would send it to Dremel to be repaired - if it is a recent model they might warranty it (they have a 4 or 5 year warranty) and if it is an older one I bet that it would be less than $40 with shipping to repair. The customer service at Dremel has been very good for me. It might save you a few bucks and also let you keep what is probably a superior tool compared to some of the new ones in service.

Just my 2 cents on that. As far as the rocket - this thing is awesome! I love it! Keep up the good work!

 

[Rocketjunkie]

I would send it to Dremel to be repaired

It's about 10 years old. The fiberglass dust has gradually worn it out. Got a new one for $54.

 

[thobin]

OH my this is getting good.

[Rocketjunkie]

A little more progress.
Blocks cut from 3/4" plywood. Final dimensions 2" x 2" x 1-1/2", sanded to fit the ID of the airframe.
Then they are bonded to the centering rings. They will serve as mounts for the Unistrut rail guides.

 

[Rocketjunkie]

More progress...
Glue the fin can into the airframe with thickened 20 min epoxy.
Lay out the glass to be used. This is 9 oz cloth, 2 layers.
Fillet all joints with silica thickened 20 min epoxy.
Allow to gel, then lay on the cloth and saturate with unfilled resin.
It took about 80g thickened and 250g unfilled epoxy along with a yard of the 9 oz cloth.
There will be a lot of sanding in the future (Sanding is one of my least favorite parts of the build process.)

 

[blackjack2564]

You've been lucky so far!

I don't see any kitty paw prints on anything or did they get glued to a wall?

 

[CarVac]

Oughtn't you keep the cats away from fiberglass cloth?

 

[Pantherjon]

That's Tom's Quality Control Specialist inspecting the cloth:wink:

Really looking forward to seeing this fly in April!
