    How do fins fail?

    I only have my personal statistics to offer: in 16 years of flying low power, LPR, balsa, cardboard, plastic, rockets I've had precisely 1 fin failure. That was on a rocket where I'd sanded an airfoil on one side of each of the fins so as to create a one-sided lift which would impart spin to the...

    When your space rocket takes the morning train

    I don't know whether everybody knows that or not, Soyuz rockets are hauled by train to their launch pad. Even though I have a few trains in large scale, "G scale" from the German word for large, also termed garden railway scale, with a 45mm track gauge and 30 inch long locomotives which weigh...

    Japan Space One

    The fall of yet another not at all intact rocket demonstrates that spaceflight's reputation for being not at all easy stands intact.

    Interesting article on lunar rover batteries

    Short and information packed. Article brings to mind a book found at our rural library last year and liked so much I bought my own copy in January this year and immediately read it. Covers the people, the process, and the hardware. Including why the cost did what it did. Also recommend this...

    anybody use pinstripe tape?

    Also a question is what was the pinstripe tape stuck to? Adhesion will be poor to flat finish paint because in order to not reflect like gloss paint does, the surface of flat paint is like microscopic sandpaper & tapes, decals too, only adhere to the high spots. Second question is, was a...

    What I did today -instead- of Rocketry.

    Draft is what the boat has. Daft is what the owners is. And then the spider web of memory connects with the 17foot long lake cruiser style hull, 3/8 to 1/2 inch, or so, keel, aluminum canoe by Grumman that Mom & Dad bought in mid 1970s. With its wide flat bottom we had a shallower draft than...

    Another Pointless Poll

    With my health and lifestyle what they now are, the two orange tabby feline rescue fellows currently sharing bed with me here, Georgie, 14 years old, at my left, and Grumman, 15 years old, at my right, are the right pets for me. They have shared nearly their entire lives with me, 😺🥰😸 Dogs --...

    What I did today -instead- of Rocketry.

    Question: Do rants use a 1/8 or 3/16 launch rod? I can't find any reference which says.

    What I did today -instead- of Rocketry.

    Ohhh I'm so very motivated to launch in to a rant about media-induced hysteria, provider and payer paranoia, and how they corrupt both the John Q. Public masses and paid professionals; & the actual, documentable, and sometimes fatal, damage it has done and is widely documented to have done and...

    What I did today -instead- of Rocketry.

    Read this while at laundromat, String, a fundamental foundation of rocket science. Roofs appear to also be a critical component of rocket science. Book doesn't say, but I wonder if it was a classic balsa and tissue model.

    NASA uses a lot of masking tape just like us!

    That brings to mind a 1970s article titled "Augsburg Eagle" in one of the aircraft magazines Dad got in the 1970s which mentioned the matte paint done to historical specs on a BF-109 someone, the Smithsonian?, was restoring. If anything touched the applied and cured paint it would leave a mark...

    The car from your past you miss the most?

    1969 Dodge Coronet 500 with the little 318 V8 which was parents' car then passed down to me. It was comfortable; it rode well; it handled well; trunk was plenty capacious; mechanicals were easy to work on and rarely needed to be worked on; even though it had power steering you had a sense that...

    Well... This Is Just Stupid... Is There A Doctor In The House? - STATUS RESOLVED (But Still Stupid)

    And there's another disturbingly common healthcare defect which needs fixing -- I'll put it this way, "Hey Doc, this is going on and it is most likely because of that." "Excuse me, but it would be appreciated if you let me do the doctoring and you stayed off Google." "Oh? Really?" "Yes...

    Well... This Is Just Stupid... Is There A Doctor In The House? - STATUS RESOLVED (But Still Stupid)

    Which is where the paid professionals go wrong. There are a number of us who weren't until as adults we burned out from the effort applied to masking for all our lives. I still remember at the age of 32 when having increasing psych and physical troubles both my GP at the time said one day to me...

    Well... This Is Just Stupid... Is There A Doctor In The House? - STATUS RESOLVED (But Still Stupid)

    I can second that! Not an officially diagnosed parent but after my parents met with my psychologist about 6 years ago, because my parents were visiting and just for fun why not since I already have an appointment ... ... after appointment psychologist said that she'd admit to going in expecting...

    True. The responsible parties may well be looking at it as a situation of: there's an entire supply chain, maybe several supply chains, we now don't have to hassle with there's fixed plant utilities we now don't have to hassle with there's fixed plant building maintenance we now don't have to...
