Hi, I'm wondering what the parts are that i would need to order from the Semroc website in order to complete this rocket. (Black Widow)

Well, you have this:

http://www.semroc.com/Store/scripts...arts.asp?ID=513

and this:

http://www.semroc.com/Store/scripts...p?idproduct=197

which gets you most of the way there. There's also this:

http://www.semroc.com/Store/scripts...?idproduct=1291

but I would email Carl and see just what that has in the pack.

One other thing, Carl is very good at being able to supply parts that aren't listed on Semroc's website. It can't hurt to ask.

Thanks. I wasnt certain what parts were included in the sub-assembly package. I sent an email to sales@semroc to be sure.

So far i have the following in my cart
-Balsa Nose Cone #7 Ogive
-Chute Pack 12'' Black and Yellow
-Decal Black Widow
-Engine Hook Standard
-Laser cut black widow fins
-Tube Coupler #7
-Parts Sub-Assembly 13 Black Widow
-Body Tube #7 4''-booster
-Body Tube #7 9''-sustainer
-Thrust Ring #7

I think thats it depending on what is in the sub-assembly. If I'm missing anything, help would be greatly appreciated.

Hey, wait a second. I'm not the world's foremost expert on Centuri models, but I have this "thing" in my collection that I need to paint. Isn't this a Black Widow? I thought it was. I got it from Semroc so at one time they had the kit. You should ask Carl.

Either that or my early-onset dementia is kicking in again.

Thats a beautifully constructed black widow. My brother had one when we were younger. We never did get that booster section to glide.

Semroc hasn't kitted it, yet. Carl has had the parts available for awhile now. I thought he did the fins for you originally? Maybe not.

Another question. I was looking over the sets of plans on the Old rocket Plans and Jim Z's sites. They seem to be very different. Which one should i be following if i am going to be building the Black Widow?

Well allrighty then, ring one up for dementia.

I honestly can't remember. Carl must have cut the fins (and fin reinforcements) for me because I am quite sure I didn't do that. I have a whole bag of the passport couplers from Semroc and I remember buying them (just not for the Black Widow).

OK, enough of this nonsense. I went back and looked up my past orders from Semroc and I see that I ordered the nose cone, couplers and body tubes back on 1/2/06. Carl must have cut the fins as a special order.

At least I now know the life of a typical memory

There have been at least three different versions of the Black Widow. That is the main reason why we have not done it yet. We have been considering an xKit of the earliest version, but it had problems staging and gliding. The later version has better booster fins and the pass-port coupler, but looks different from the original. I think I have the latest version around here somewhere, but I have not seen it in a while. The laser-cut fins are also for the latest version.


PSA-13 is for the latest version of the Black Widow and contains:
A 1 HTC-7B Tubing Coupler #7 Outside 1.0" Long
B 2 TB-7 Thrust Block #7
C 1 LL-122 Launch Lug 1/8" x 2.25"
D 1 SE-10 Screw Eye 1"
E 1 EC-118 Elastic Cord 18"
F 1 SCK-24 Kevlar Thread 100# 24"
