I managed to get one from the first run at 0700 yesterday, took a few tries to process the purchase though. Too good to pass up.

Consider using removable nylon rivets. PML has them listed on their hardware page: https://publicmissiles.com/product/hardware Amazon has some too: https://www.amazon.com/dp/B008MP06SG/?tag=skimlinks_replacement-20 They come in various diameters and lengths. McMaster has a wide...

I got my first ham ticket back when I was 13. I took the General exam at the FCC office in San Francisco and the Extra in LA. They used tubes back then and you could get shocked on the straight key during the transmit portion of the CW test. Old school. :)

Printed membership cards for club members :)

RIP

1) Found my workbench. 2) Ordered a PML Quantum Leap II with .125" fins.

Feynman's Lectures on Physics are a wonderful read. Some math required. I have the paperback versions, the hardcover editions are a bit pricey. https://www.amazon.com/dp/0465023827/?tag=skimlinks_replacement-20

RIP. I'll have to get that documentary. Thanks for the reference.

Dang Tony. I didn't know that. I hope the endoscopy turns out well. I used to smoke 4 packs of Marlboro per day. I quit cold turkey ~32 years ago, it was the hardest thing I ever did. I was a royal @ss for about a year, some say I still am :) I do have an occasional stogie nowadays but...

I had to laugh when I saw that image. Kids would love it. Here's a really big one. https://www.thislittlepigstayedhome.com/wp-content/uploads/2014/07/sandwich-6.jpg

Somewhat dated but these are the stats as of July of last year. https://www.zerohedge.com/news/2016-07-08/breakdown-us-citizens-killed-cops-2016 And more info on black on black crime. Kappy really needs to address this too...

Thanks. I'm using similar temps. My "chamber" doesn't get anywhere near 70C, maybe 40C on a warm day. I'm space limited at the moment so a proper chamber will have to wait. My big problem with ABS is delamination. I've been using some IC3D ABS filament with reasonable success although I...

Fun thread, I'm paying more attention to your printer than the rockets :) I also have a deltabot, an OpenBeam Kossel Pro. I'm printing mainly in PLA. ABS is a real PITA at times. I've had more failures than successes with ABS. My printer is in a small closet so it's nice and toasty during...

+1 They send out lots of email though so be ready.

<rant> I'm a niners fan. However, I've not watched a single NFL game this season, largely due to Kaepernick's antics and the political BS which runs rampant in the NFL. As long as he's still in the NFL, the niners and NFL can suck eggs. I plan to be cleaning off my workbench during the...

Look on ebay. You can find chopped/milled fiberglass and carbon fiber in varying quantities for reasonable prices. https://www.uscomposites.com/ is another great source for composites.

Ok, that's good news. I was concerned that the variety and competition was drying up. I also have some black FG I got from Wildman so it would be good to have an alternate source.

Ha! That wasn't there yesterday :)

If you want your club to recycle, contact your local club officers and volunteer to coordinate the recycling.

Yes, it has. For example rocketry warehouse had dozens and dozens of different airframe tubes, around 6 or 7 pages worth. Madcow has 1 page. It skips over 5" entirely and stops at 5.5". Wildman is similarly restricted from what they used to offer. I'm sure their quality is fine, I just need...
