Model Forum / General / Rockets / December 2005

I’ve been off work due to ill health for the last couple of months. To
save me from watching the horrors of daytime TV, apart from building
rockets of course (which is strangely therapeutic), I started work on a
fun rocketry inspired project.

I have some questions regarding the ratio of motor diameter, core diameter
and nozzle choke diameter.
i have seen ratios such as 1" id tube, 3/8" core, 3/16" nozzle
first is this a good formula? second if i wanted to make a 2" diameter

Does anyone know where I can buy some molded plastic fin units?

Some of you might find these interesting. :)

Is Art Rose still selling fin alignment jigs?  Anybody able to send
Art's contact information to me offline?  Thanks and happy holidays!

Did anyone catch the new car ad that shows an Estes Mod Roc being launched
and it flys just about the ground across a field and threw trees in a park
and crashes into a newspaper ad for the car and crumples. ?

Everyone,
A whole series of new plans are now available on the PROVEN page of the
BARCLONE website, including the PDF Instruction Guide for the Cherokee
Double-D, which had its very early discussions on the Yahoo!Groups

Hobby Lobby again has 1/2 off rocket kits and starter sets (but NOT motors),
but not motors. Also plastic models, die cast models, trains, and race sets.
Their internet coupon is 40% off any one item, which CAN be used for a pack
of motors.

I am looking for a supplier of Areotech engines in Ontario Canada. If one
was around Toronto, even better. I used to buy from ARG now Sigma Rockets in
Mississauga, but he won't return my emails or calls anyone. Maybe he found
me to be a pain or has enough money now. I am a member ...

I'd like to buy a copy of "Fourteen U.S. Army Missiles of the Cold War"
but NARTS is out of stock.  I don't think Peter has any more.  I've
checked a lot of online vendors with no luck.  Do you know of a copy for
sale?  Thanks and happy holidays!

This message is to announce that Teleflite is selling some brand new and
collectible 1992-vintage "Rocket Man" video tapes on eBay. Here's the link

Lord... take me now...
Icicle lights...
About 22 miles of them...
Approximately 50% are working....

Well, after chainsaws, and snowblowers, I figured I'd at least make a
feeble attempt to get back on topic...
