9, ordered from Estes catalog 631, 42 years ago. Still trying to get it right. If I can't get it right, big, fast and loud will do.

I've had Dragon since last time I had my bionics tuned up, in 2001. I almost needed to do my whole dissertation with it, but the research ran long and my hand got better. IIRC, Microsoft bought them out and built it into Word. Or maybe that was a different voice-to-text. But Dragon does work...

With Fred's permission to continue.... I'm well aware of the laws. I know them as well as anyone. I happen to know someone who works someplace that ships them and has the proper permit to do so, and he can ship them for me. And please mind your manners. There's no reason good enough to be...

For comparison of prices for this vs. the system new, as well as cost of replenishables, see https://www.mrfiberglass.com/vacuum_bagging.html The West Systems book should be first on your list. Although Aerosleeves is no more, you can find the tutorial from their web site via the Wayback...

That's where I think this should go. Thanks to all who sent kind messages regarding my upcoming plumbing repairs and bionics replacement. It won't be a cakewalk, but things will straighten out over the next year or so. Maybe 2 in the highly unlikely event I get a new liver. Before I go in...

Here's some evidence that a long section of it can handle some stress. Everything between the fin can and the reducer is Quantum. I crammed it straight up on an Ellis H275, a bunch of acceleration. OK, only about 13 Gs, but there's a lot of length there for wobble to build up, and it didn't...

I bought a vacuum system for composite parts construction a couple years ago, used it twice and it's been sitting ever since. Here's a link to one for sale through Amazon so you can see the specs: https://www.amazon.com/dp/B000LBBJGM/?tag=skimlinks_replacement-20 There's no for picture for...

Thanks for the messages folks. Everything is gone.

I'm not dead. Just taking interferon chemo for the next 6 to 8 months, then a complete rebuild of my titanium wrist, another 3 to 6 months offline. I'll be back next year, but handling reloads will be a bit of a problem for my new bionics. For sale: 1 Aerotech 29/40-120 motor, VG...

Thursday evening I was coming back from a store other than the one I set out for. I had a very minor head on, damagaing only one headlight.The policae arrived and did everything right, xcept ask me why I was on the street. I have no answer. Serveral hours later, about 4 AM, I was returning (I...

Will do, Nick. If you want to do this, I'll help organize including contacting vendors and NAR folks. I'll provisionally offer to administer at least some of it, with the understanding that if I get a job out of state I may have to drop some or all of that part. Taking on a new teaching position...

Agreed. A (fractional?) multiplier for one vs. two levels of separation. I see no problem with having more than two people on a team, as long as every team is a distinct entry. I'd discount points for two adults/senior members. A main point is to have the adult/senior teach and supervise, and...

I think that's an obvious assumption. But I believe it's incorrect. It might occur to some people, but just about anyone serious enough about rocketry to contribute to EMRR contests have more sense.

Nitrile is the stuff to use. If they're cheap, thin ones, use two pair if you're going to have your hands on it a lot. If you're just using them to smooth fillets with your fingers, cut the fingers off the gloves and slip two onto one finger. It's easier to work with. Wood filler will cover...

I like future. I've only had one bad result, when I put too much over white appliance epoxy. It yellowed with age, and more so on the glued-on paper "decals". Yes, it's an easy fix (remove with ammonia water and recoat, no problem) but I'd just as soon not have to. Everything else I've used it...

And the movies you haven't seen there weren't. Sometimes absence of evidence IS evidence of absence, but only of absence, not non-existence. Nothing is in IMDB until it's submitted.

I think he's concerned about a greenhouse effect; heat building up from sitting in the sun. Highly reflective opaque paint is the first thing. Low heat conduction is a second concern. Both would be well handled by Rustoleum white appliance epoxy paint. It sticks well to plastic, is very...

I can attest to both. In a bad motor CATO the snap ring might blow out. One caveat: if you use motors with no rear retention ring (like most SU motors) , make sure you use the included washer between the motor and the snap ring. It reduces the open diameter. Without it, the ejection will toss...
