Okay, when ejection charge fires, it is hot enough to Melt a parachute if there isn't enough wadding. Burn through Kevlar if attached just in front of motor mount (at least thin Kevlar) For zero delay motors, the burn through sends hot gas sufficient to light the sustainer. So why doesn't it...

I‘ve got this online, does it sound right? 50mm (L) x 32mm (W) x13mm (H) my cameras are not available for measurement, and I am working up an origami box style camera mount to go on an airbrake recovery rocket. thanks!

There used to be a “test” section, if so I don’t see it. Anyway, I’m working on a design and have been appropriately “advised” that my build threads are hard to follow. So this NOT meant to be followed, just a place holder for pics and stuff, I will God-Willing due a “built” thread that will...

Short version is if you reserve a car AND pay for insurance, supposedly pay to the counter, if for whatever reason you cancel, MAKE SURE THE INSURANCE GETS CANCELLED TOO! Rest is long winded, so feel free to bail out now, unless really bored. My wife went on a trip and flew Delta, I was buying...

Anybody know of a used late model Mercedes S Class all wheel drive for sale, preferably 2014 or later, under 100,00 miles? Thanks

My wife has a thing for a certain luxury car, no way we can swing it new, and there are not a lot of used ones on the market in Washington state. looking at some of the online sites, AutoTrader seems to have best selection if you go nationwide. I have set my filters for the make and model, all...

Haven’t seen anything from Scotty Dog in a long while. ? @Scottydog1 ? Anybody know if he is okay?

Hey, at least it's not a glue thread. We have some toilets we just about never use, there are hard water stains around the water edges. We have tried just about everything. Ideas (other than replacing the toilets) appreciated! We've tried high powered vinegar and baking soda. Thanks...

The bottom ruler came with a set of knife blades from Amazon. The upper ruler from Hobby Lobby. Can’t complain too much, it was freebie. Took me a bit to figure it out.

No, I don't get a kickback. Anyway, I tried ordering a while ago, said free shipping, got distracted, and when I went back the next day it was no longer free shipping, was like$12. Went back to website today and was free again for over $50. I picked up some balsa sheets (6x36 inch, 1/8 and...

I am not talking traveling with the rocket (in which case they may be oversized baggage) I am talking shipping a built rocket (without motors or igniters) to another person say to Hawaii or across the US. Size say 3 feet x 1 foot x 1 foot. No rush. I am guessing USPS, but wondered if anyone...

This is 1/32 ply glued to 1/8 balsa. Problem with watching football while building (at least Air Force won, games don’t get much closer or crazier than that!) I don’t have a heat gun, can I bake this in the oven at 100 degrees centigrade to weaken the glue?

okay, again I guess I better start re-establishing my credibility and actually build something. I Found one of my old Air Brakers, and want to redo it to make it practical. playing around with trying to make this easier and more consistent. also trying to see if I can get two rockets out of...

Not sure why just started, but we now have bats roosting on the stone edges of our covered porch and some of our eaves. I don’t have anything against bats but they poop on our porch floor. They aren’t there during the day, I have seen a few at night. They are not there in daytime, so I guess...

My wife and I petted Lucy as she took her final nap on this earth yesterday morning. She went to sleep peacefully (although she did ask for seconds on the whipped cream treat the vet used to distract her from the sedative shot!). she was a stray we found on the street, returned her to her...

https://en.wikipedia.org/wiki/Lockheed_Martin_X-59_Quesst Hmmmm, not sure if @mbeels , @neil_w , @burkefj , or @lakeroadster or some other talented craftsman is gonna have a go at this. Might even get @hornet driver back into the game!

Okaaaaay, here's my proposed submission to National Association of Rocketry to make this a competition category. Feedback welcome. @Dotini , this is basically your ballpark, so if you want to quash it that's okay with me. I have to get this in by September 1, 2023 to get it considered for...

11 scratch built and a PortaPot Shot courtesy of @cwbullet . Fingers crossed!

I think using the Vacu-Form nose cone makes a big difference. I am getting beautiful flights with both the three fin and slanted ring fin cans . What a like about both is the rocket lands with the fins or ring UP. So there is no damage.
