Here is the MSDS on PL Premium.http://www.stickwithpl.com/pdf/PL%20Premium%20msds.pdfAll the temperature ratings seem to be before curing..??They are pretty low. Flash point is 250 Deg.I have two tubes that are going to be used on my next8″ rocket.I used it on a…   Read more»

Interesting. You learn something new every day. Is the PL the same poly base as LN?

I’ve had some success using PL Premium polyurethane glue. I built a rocket fin can as described by Edward: See the Forum “Construction Help” Thread titled “Fin Options”.The construction technique described by Edward seems to work, but I’ve only tried…   Read more»

Statement removed due to foot in mouth condition, or is it brain fell out before hands typed…. DOOOOOH

Up to my armpits in getting inventory squared away, in my mind at least. Yes, I’ll be bringing a supply of motors -let me know what you want/need at Motojoe4GLR@yahoo.com

I sure would have liked to see Joe’s face on the way home.

Mike, he’s probably still smiling.

I sure would have liked to see Joe’s face on the way home. Fun..Fun..Exciting..

8) Well, Joe was at my place today, Monday11/23 and I sent him packing with all of the Giant Leap stuff. A whole van full. He has my grey boxes that I set up for launches, so we should be…   Read more»

Unfortunately, if you publish it before you apply for the patent, your patent rights are pretty much shot.I’ve long thought about head-end ignition, but the only idea I’ve come up with involves drilling two holes for conductors through the forward…   Read more»

The anodizing will help to keep the contact down. I’m planning on machining the ends so that there is .015-.020 between the plug and the wall on each side.I’m trying to avoid drilling a hole all the way through the…   Read more»

As long as you’ve got a good thick anodize, you shouldn’t have to worry about incidental contact between the plug and the closure, because it will happen, even with perfect o-rings.You could take it a step further and do the…   Read more»

I’m going to be doing airstarts, so in effect a 2nd stage. I didn’t want to have to have a way to hold the igniters up at the top of the core and didn’t want to swiss cheese the back…   Read more»

We used to fly head-end Kosdon East motors. They weren’t as elegant as Edward’s, but they worked…

My suggestion:Patent it. Quickly.That’s a simple and elegant idea. It would also be perfect for igniting the upper stages, eh?

Self moderation – I like that.

Moved to “Electronics”…

Yes, there are a lot of sensors out there that people have hooked up to this device. 6 DoF accelerometers like you mention, gyros, baros, GPS, radio telemetry, servo control, horizon sensors. Other than tracking and data gathering, I was…   Read more»

Ardupilot projecthttp://www.sparkfun.com/commerce/categories.php?c=23&sidx=pd.products_name&sdir=ASC&sipp=100&page=1I was reading about that. Check this out, number 4 & 5 down the page. 6DoF, plus I saw a 3 or 2 axis accelerometer at +/- 250 g’s. Too much, and there’s one that is +/- 16-18 g’s….   Read more»

I’m getting close to going for my L2 and am already feeling like I’m going to need something to keep me truly engaged in rocketry. It’ll be a while before L3, so in the mean time I’ve been thinking of…   Read more»

Sean, that was so cool! At least, I’d have a reason to use all those old 386’s and 486’s that I just couldn’t throw away… My next flight will probably be at Mach 1.5, and I’m thinking about some sensors…   Read more»
