I wasn't sure where else to post this but are there any general guidelines for the shelf life of unopened hobby epoxies (Hangar 9, HobbyTown, etc.)? Does it make any difference whether it is 5 minute, 12 minute, 30 minute, etc.? Second part of the question is once opened (but capped) how long do...

For someone who has limited power tools (me) how would you recommend cutting slots in Dyna-Wind (Giant Leap) tubing for G10 fins that you don't want to got all the way to the end of the tube?

Can someone explain the difference between water-based and waterborne spray paint? What are the advantages/disadvantages of each and why would you use one versus the other?

Someone in another group just informed me that the owner of TLP has moved to Florida and plans to start shipping again in August - including 6 new kits.

I've started building my Semroc SLS Laser-X and I have a question about the unique interchangeable motor mount. The stock kit comes with a 29mm motor mount and relies on friction fit for the motor. I'm not opposed to this but I was wondering if anyone else has built this kit and did you modify...

I want to purchase a section of 1515 rail (with 5/16" slot) to use for larger rockets with larger rail buttons. The question is do I purchase the regular T-slotted aluminum with solid corners or the "lite" version with hollow corners? They both have the same specs in terms of dimensions but the...

I went to my local marine store today to purcahse some West System epoxy and the shelves were bare. Instead there was a big display for MAS Epoxies which I had never heard of until today. The kind folks at Boater's World proceeded to tell me how superior this stuff is to West System but then...

I purchased my first QModeling kit - the Mega Retro Series Bullpup. I will dispense with the step-by-step pictures of the building process since they are very similar to other QModeling kits that have already been documented on this forum. I thought the instructions were good so I followed them...

What do you guys and gals do to protect the aft end of your rockets (mostly mid and high power) from the heat and flame of motor exhaust? I'm tired of taking the time to put a really good finish on my rockets only to have the rear end look like it has gone through WW3 after a couple of flights...

This may be a silly question, but does Estes stamp/print production dates on their BP motors? I'm looking at several "numbers" on various motors that I thought were dates, but they do not match what is printed on the bar code tag that describes the contents of the package. Just curious...

What are you guys and gals using for a TV Tuner on your PC (PCI or PCI Express)? What kind of system are you using and what do you like/not like about your card? Does it include FM?

Jim Ball hasn't updated his Yellowjacket Launch Systems web site since May and I've sent a couple of emails with no response. Has anyone else had any contact with Jim and know if he is through with his move and back to making launch pads again?

I have used 0.25" phenolic tubing as guides for my alitimeter/electronic sleds to slide over the all-thread in my ebays. I've gotten this in the past from Jim Amos at Missile Works but he is getting out of the tubing business and I purchased the last few pieces he had. I know there are other...

Well it finally all came together this past Saturday at the Battle Park launch in Culpeper. First, you couldn't have asked for better weather on Saturday -- very little wind and temperature in the 70's! Some of you may recall that this was to be my third attempt for my Level 2 certification...

What do you use/recommend for managing digital images (photo gallery) on a web site? Any good examples?

The Vikings had their monthly launch this past Sunday and as usual there were various FlisKits taking to the skies. I did get a good lift-off shot of Steve Smith's newly constructed Tres. He launched on a cluster of B4-4's which was a little ...yawn... underwhelming to say the least, but it was...

Well, I finally got around to finishing my first Excelsior Goonybird -- the Goonybird Zero. Turned out pretty well... Phred, I'm already thinking about an upscale of this based on the BT-80. What do you think?

Several months ago I purchased what I thought was 3.9" LOC BT from an on-site vendor at a launch. I later purchased a LOC 3.9" electronics bay kit directly from LOC. The LOC e-bay/coupler tube does not fit what I thought was the LOC 3.9" BT (coupler diameter too large). I also have a Giant Leap...

I know I'm losing my mind, but I could have sworn I either read in a forum or got an email today about a "system" that would allow you to print dry-transfer decals (including white) with a laser printer. Anybody know what I'm referring to?

I'm trying Future Floor Finish for the first time as my top coat and boy this stuff is thin! I do not have an air brush and will be using a foam applicator. Any tricks or suggestions for best results?
