Can anyone help me with plans for the old Centauri Egg Crate ? I know it's a BT-60 (estes equivelent) body and a BT-70 payload section, but I need tube lengths, and a fin pattern would be REAL nice !

Anyone ? You would have my undying gratitude ! That and $3.75 buys you a latte at Starbucks......

The payload section is ST-20 which is larger than BT-70.

I know, but the difference is a little over 1/10 of an inch, not enought to matter to me. What i really need are the tube lengths and a fin pattern.

The Centuri Egg Crate is exactly the same as the much newer Estes Eggspress except for the Engine mount and fin pattern.

The Estes kit used a single 18mm engine mount. The Enerjet E/F Eggcrate useda 29mm engine mount. The Centuri Egg Crate used a 3x18mm cluster engine mount. The fin pattern can be found attached below or use the link below.

No, you're thinking of the Enerjet Egg Crate. The Centuri Egg Crate was completely different.

Scott;

I thought ST-20 had an OD of 2.04" while BT-70 has an OD of 2.217". That would make BT-70 bigger.

I do understand that there is some difference in the tube sizes. I mostly want the fin pattern, and tube lengths would be helpful also. if I have to, I'll just wing it !

I was browsing egg lofters and ran across the Egg Crate (KC-11) in the 71 Centuri catalog - it struck my fancy. A quick search of the forums led me to this thread, but, alas revealed no plans. :p So I took a stab at reproducing the model from the catalog :eek:

Parts list:

Nose cone: Semroc BC-2033
Payload tube: ST-20, 5" length
Transition: Semroc BR-1620F
Sustainer body tube: ST-16, 10.5" length
3 ST-7 or BT-20 motor tube, 2.75" length
3 Semroc TB-7 thrust Blocks
Launch lug: Semroc LL-320
Parachute: Semroc CP-24

Here's the Rocksim 3D image of the rocket:

I won an Ebay auction with parts to the Egg Crate, and they arrived today:

http://www.billcooke.org/images/Construction/Egg_Crate/Egg_Crate_parts.jpg

The chute wadding was an unexpected bonus, but the 1970 A5-4 motor caused me to cringe a bit. Priority mail ain't the way to ship those things :p

Measurements are:

Payload tube - ST-20, 5" length
Body tube - ST-16, 12" length (note balsa coupler glued in one end - more on this later)
Nose cone - 2.5" bezier, exact match to Semroc ST-2026

Fins (I will scan and send in patterns on Monday):

Root chord - 3.0"
Tip chord - 1.7813"
Sweep length - 2.2813"
Sweep angle - 45 deg
Semi-span - 2.2813"

Launch lug stand-off:

Root chord - 2.0"
Tip chord - 1.625"
Sweep length - 0.1875"
Sweep angle - 45 deg
Semi-span - 0.1875"

As you can see there are 2 launch lug stand offs on each sheet. I sincerely doubt this puppy uses all four, but suspect it does use two.

I puzzled over the lack of a balsa adapter, and originally thought it had been lost with the instructions, decals, motor tubes, etc. I also could not figure out why there was an ST-16 balsa coupler glued into the body tube and why a paper ST-20 coupler was in the parts. I did some ciphering, and figured out that using a Semroc BR-1620F adapter would put me at least an inch over the rocket length given in the catalog. :confused: I couldn't figure out what was up, and had about decided the length was a typo.

Then it hit me... :o

I went over to the parts section of the 71 catalog, and noticed there was no balsa adapter to connect a ST-16 to an ST-20 - there was only a paper one, the PR-1620, which had a shroud 1 " long.

Mystery solved - I think.

The Egg Crate used a paper shroud - seems kinda crazy for an egg lofter - and part of the ST-16 (over an inch) was used in the construction of the adapter. The balsa coupler was then used to connect the adapter+payload section to the body. Length problem solved.

Does anyone have any instructions to verify the above (and also to tell me if 2 launch lug stand offs were used)? Pretty please? :D

I am planning to clone this, but may make life simple and use a Semroc BR-1620F - at 1.2", it is a little longer than the PR-1620, but a 10.5" body tube would provide a match to the catalog length. That would save the trouble of constructing a paper one, and eliminate the need for a balsa coupler.

Now to work on drawing the decals - looking at the pic on the inside back cover of the 71 Centuri catalog, they consist of a black and red roll pattern, and a couple of lines. Also looks like 2 horizontal strips of silver foil along the egg capsule.

true - although shipping this rocket kit / items shown , regardless of the engine, is ILLEGAL to ship MEDIA MAIL , which is for periodicals / books and media ONLY.
the selelr could face hefty fines is caught shipping non-media items via media mail .

Since I don't like RockSim I drew it up in Illustrator. Here is a PDF of the fins, make two sets ;)

I'll also attach a CorelDraw! file which Carl can easily cut on his laser cutter. Since the forum won't let me upload a .cdr file I zipped it up.

BTW the root isn't *exactly* 3" per your scan. Should it be adjusted?

You are correct - a more precise measurement is 77.0 mm = 3.03".

Anybody got a suggestion on how to gen up the decal? You can get an idea from here (http://www.ninfinger.org/~sven/rockets/catalogs/centuri71d/71dcen24.html) and the colors by looking at the yellow and black rocket near the top left here (http://www.ninfinger.org/~sven/rockets/catalogs/centuri71d/71dcen96.html).

Sorry, been at our place up north over the weekend.

I had also bid on that lot. ;) I have my original Egg Crate here that is 95% built. I wanted to get the fin set mainly to scan the templates. Bill, thank you for scanning the fins for us. Yes, this kit uses a paper shroud reducer. I have my original instructions and decal still. Unfortunately, it is buried at the moment. As I straighten this mess up down here and uncover them I plan on scanning them for YORP. The kit also had three motor tubes and used engine hooks vs friction fit.

Kurt can attest to the rocket mess in my basement. Actually, I think it's gotten worse since the last time he saw it. :D

Before you build it you may want to consider sending the cone to Semroc so they can get the proper dimensions for duping it. I'm not sure they have that one in their stable yet.

Here's a comparison - looking at the pic, you can see that the original Egg Crate cone is slightly more rounded than the Semroc BC-2026, though they are a close match. Still think I should send it in?

What do you think, Carl? You wish to try to replicate this puppy?

Phred,

71 Centuri catalog says this is a 2 or 3 18 mm cluster - Looks like you have a choice.

As far as the paper adapter, I'm pretty sure it was a PR-1620, which had a 1" shroud (see lower right of here (http://www.ninfinger.org/~sven/rockets/catalogs/centuri71d/71dcen62.html)). The adapter cosnsists of a ST-20 coupler, a couple of #16 to #20 rings (didn't see these on the Semroc site), and the 1" paper shroud. The shroud can be easily generated from card stock using the cool programs available.

My Ebay purchase did not have instructions, so I can't give any more details. I think someone was going to post them once they had a chance to go through their kit collection.

EDIT: As far as the length of the coupler, I do not know. Catalog gives a standard length of 1.75".

Yeah Scott, I know how you feel. I have just started cleaning out all of my cardboard zerox boxes full of kits, and sorting them into 90 quart Sterilite containers. I figure the Sterilit plastic boxes are safer in case of minor flooding... 2 of these stack neatly under my slot car track, so it is very convenient: 1 box for vintage ESTES kits, one for numbered Fliskits, Semroc, and Scott B's kits, 1 for Centuri, 1 45 Qt for Goonybirds, and another for Canaroc. 2 for 'builder' kits.... Rather than getting organozed, my basement is now a total wreck with kits EVERYWHERE!!

I built one of these when I was a lot younger. Who ever had this kit glued the balsa coupler into the wrong tube. The balsa coupler, a tube coupler, a pair of fiber centering rings, and the 1" shroud made up the transition. As far as the launch lug standoffs are concerned, each piece you cut out was half of the standoff. In other words you glued two pieces together to make one stand off.

I'm finishing up an Semroc Egg Crate model and will be using the same paint scheme as your very nicely done model. :)

Bob-

Must be a bit of an Egg Crate craze......I just finished up (last month) an original Egg Crate kit build, which has been in the works literally for years. I had construction done several years ago, but never did work on the final fill and finish until the past few months, between some other builds.

It's all original vintage stuff, and even the decal (43 years old as it was) held up (thankfully!).

I had always loved the paint scheme of the Egg Crate on the inside back cover of the 1971 Centuri catalog, much like Bill has done his. As an eight year old kid (that catalog was my first ever rocket catalog), I was mezmerized by the size of the nosecone being held 'in hand' on the catalog page featuring the Egg Crate (the only catalog the Egg Crate would ever appear in).

I eyeballed my silver metallic paper bands at 1/4" wide. I also cut my payload tube down to 4" instead of the kit standard 5", since my careful eyeballing (and measuring) of the kit photos in that catalog led me strongly to believe the catalog model did NOT feature a 5" payload tube....it featured a 4" tube.

I got a couple of the Semroc Egg Crate kits and will probably build one a bit later after I get a large backlog of finished builds painted (I'm baaad at buidling and then moving on to another build before the latest one is totally painted and decaled.....I'm probably not alone in that regards).

One photo attached of my Egg Crate sitting atop a Centuri LIA-77 launcher....one that I will use when I finally fly this bird. Made three engine mounts for this one: a single, double, and triple 18mm mounts, all removable.

Bob-

Must be a bit of an Egg Crate craze......I just finished up (last month) an original Egg Crate kit build, which has been in the works literally for years. I had construction done several years ago, but never did work on the final fill and finish until the past few months, between some other builds.

It's all original vintage stuff, and even the decal (43 years old as it was) held up (thankfully!).

I had always loved the paint scheme of the Egg Crate on the inside back cover of the 1971 Centuri catalog, much like Bill has done his.

Wow! Earl, that is very nice! Love the matte black of the nose cone / payload section.

Thanks, Joe.

Yes, the catalog model in the '71 catalog featured matte black paint on the nose cone and payload section. The silver metallic paper bands look nice against that color and then the yellow paint sets off the booster well.

It's a nice paint combination and roll bar decal (I REALLY like that roll bar decal!) that the original Egg Crate designer did such a great job with, and something I wanted to try to replicate as closely as I could.

Sad that the kit was offered only that one year. Original kits are harder to come by than the 1/45th Little Joe II and are just as expensive it seems. :o

Hiya Bob!

The silver bands are 0.25" in width.

Looking forward to seeing your build!

Really nice. Love the color combination. Cool thread you link to as well.

I bought and built the Semroc Retro-Repro and it's a fine kit—one of my favorites http://forums.rocketshoppe.com/showthread.php?t=10356&page=5&pp=10&highlight=foamy%27s+kitchen).

I wish I'd had the foresight to purchase an extra one before the end. Of course, I can say that about a lot of things.

As far as official Centuri colors go... it seems that catalog schemes were dictated by what two colors were being used on a given page. Usually, printer's spreads (what two pages would be printed with the same plate) were the same two colors; black and whatever. The color patterns are the only things that would be consistent from catalog to catalog. What they actually painted their "showroom" models was almost always something different/simplified from what the catalog schemes were. I think the catalog schemes were "ideals" and I've never felt bound to them. Though, sometimes, they are just the ticket. Particularly after lusting after a model and finally being able to build or aquire it.

Okay, I finished my Semroc Egg Crate model.

I really like this color scheme. :)

First flight will be at NARAM-56. It will be a tribute to Carl.

Looks great....kinda partial to that color scheme myself. ;)

Carl would be proud of all the tributes to him. I've got a USS America that I am about to put final decals on that I'd like to rename the USS Carl McLawhorn. He did another great job with that kit....don't know how he did so much in such a relatively short time.

Post some pics of the flight after NARAM if you can. What motor arrangement do you plan to use for the first flight?

Excellent. Real nice build of a cool rocket. I'm partial to the design.

Anyone have insight as to why it was only produced for one year? I know it was an Enerjet offering the next year—but that's a different rocket.

Thanks, Earl.

I will post pictures of my Egg Crate NARAM flight. I plan to be posting from the NARAM hotel.

Still not decided on what motor(s) to use. My Egg Crate has a weight/mass of 3.8 oz w/o motor(s). I don't want the model to get away from me.

Thanks, Steve.

Your Egg Crate turned out pretty nice also.

You'll be able to see mine fly at NARAM-56.

I have contacted 'someone' who may have the answer to this question. ;)

Go for mission points and put an egg in it!
