Thnx Dan I been looking to find 1/4" pvc for other reasons The see thru tubes are also interesting. heck' for like 12k we could build a 12"round x 1o' tall...
... Ya, They certainly had the boost worked out for a rather fat and heavy rocket. I've seen 4" fuselage designed to carry cams aloft to 20k' using less fuel. ...
I recently came across this simulator: http://www.leosingleton.com/projects/rockets/ <http://www.leosingleton.com/projects/rockets/> I hadn't seen it before...
Hi George, The parachute generator looks interesting. I might have to order some more fabric in and give it a try as one of my chutes is still hanging from a...
Hello, just joined the list. I had flown the Estes rockets as a kid but have been more into model airplanes afterwards. I have been building some simple...
Hi Bill, Welcome to the forum. I haven't seen this particular kit before. Do you have any pictures of what was in the kit, as the website does not provide a...
Here's a video of a flight this morning: http://www.youtube.com/watch?v=unMZugsykn4 This was good flight but something is going on that I can't explain. I've...
Hi Pat, Nice video again! :) I remember Damo a few years ago making a similar observation with a coupling and a 22mm nozzle. What you may be experiencing is...
George, I think you nailed it. I'll try something like that on my next wrocket (which should be soon since I get about 10 flights out of each before they...
Hi All, I succesfully launched my rocket with a magnet tumbler parachute side deployment system... After two succes launches the 3d drilled itself in the...
I read about this industrial adhesive which is now available as a craft glue, apparently a derivative of "Shoe Goo". Since Shoe Goo has been discussed here...
I've used E6000 interchangeably with Goop for years here in the US, and as far as I can tell it's identical. Someone told me once that all the various...
Since the question of glue often comes up, I was thinking it may be worthwhile coming up with a simple standardized glue test that anyone could easily perform...
Looks good Grip with vice grips? Any thoughts for a test to see how well a glue would handle the swelling of a pressure bottle? ie.brittleness? Ralph...
I previously posted the latest flight of my 6 liter wrocket. Here's a video of flights 1 through 10 thats shows the process of trial and error (mostly error):...
Hi Ralph, That is a very good point. The glue needs to have some flexibility otherwise it may crack and leak even if it doesn't fail completely. I wonder if a...
Hi Ruben, Good to see you have had some successes with the magnet tumbler mechanism. I'm looking forward to the pictures. Please include details of the...
... It probably is. See <http://www.e-6000.com> - that's the Goop company. There are 3 versions listed there though - same thing with different additives. I...
... That's why E-6000 is often used to join materials having different rates of thermal expansion. Some of the physics/engineering concepts you'll need to...
I like the glue testing ideas. Sure wish I had time to do some. I think the static test of pull apart is good for comparison of adhesion. But, for our...
Maybe we're talking about different things here, but the one time I tried Goop in the past, it caused cracks to form in the FLT plastic, possibly the PET...
We're talking about the same thing. It does that to polycarbonate (FTCs), but not to PETE (bottles). Incidentally, I've never used this glue for splicing, only...
I've just finished most of the repairs on my launcher, and was going to start putting together a booster... But it's been a LONG time. I can't even remember...
I would say that using a hot knife would be fine for cutting off the bottoms of the bottles if you plan on curling the edges afterwards. But dont use a hot...
Hi Ed, I find that the slightly rough edge from cutting with scissors really doesn't matter for curling the edges. As you put the bottle on the hot plate any...
Thanks for the response, George. I think I may have made that same discovery about cutting along the side of the bottle closest to the floor (rather than the...
I agree with your tips George. But I am still interested if someone out there has come up with a way to quickly cut the bottles, other then the slow method of...
... I've seen simple wooden jigs used. Two lengths of wood are fixed at right angles to each other to make an L shape, with an end stop across one end. The...
