gonna conduct a 'spearment...
« on: September 25, 2015, 11:42:36 AM »

  Some time back Bill Wilson and I were talking about how to keep model glue/cement from attacking foam, and the suggestion was made to put a coat of alephetic resin (yellow glue ), let it dry, then try some glue on that and see if it attacks the foam, so I gonna try it...

  What say  y'all ???

Go for it!  Aliphatic glue has a reputation for not accepting glue bonds well, so don't be surprised if it doesn't work.

What's the matter with gluing with epoxy, or just using aliphatic glue in the first place.

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

   If done properly, that will work fine. I did something like that for a science fair project that involved laminating 1 lb white foam into a block 5" thick. Even at the time (which was about *40 years ago*, to my astonishment) I knew that you couldn't just glue it together with Titebond and have any chance of it curing. Failing to find any water-soluble contact cement around central Arkansas in the 45 minutes we looked, I coated the foam on both sides with a 50/50 mix of Titebond, water, with some Knox gelatin (per Ron St. Jean's "Structureless foam composite" article), and let it dry. Then used regular solvent-type contact cement.

     This project required  taking this blank of 5" thick and about 3 feet in diameter, and turning it on an ersatz faceplate lathe into an aerodynamic shape. We just took after it with various tools like woodturning chisels and Surform tools, and eventually sandpaper. I guarantee you that if you go into the garage of the house at 1410 Lenore Street, Benton, Arkansas, and look around in the corners, you will still find white foam beads floating around in there from this effort. The single biggest mess we ever made.

Back in my Carrier days I used foam wings on my .15 carrier planes and used Titebond mixed 50/50 with water and it worked great.

   That's between me and the Grays.

p.s. they appear to have renumbered the houses, it's now 1458 instead of 1410. The front yard of that house was also witness to one of the most spectacular, profligate, and irresponsible use of fireworks ever undertaken in central Arkansas, July 4, 1976. We started the day with *12 gross* of bottle rockets, and that didn't last past 1 in the afternoon, to give you a sense of scale.  You basically couldn't see the grass in the front yard for all the debris. That was also the year we mastered the art of *throwing* bottle rockets with great accuracy. No innocent bystander within 1/2 a mile was safe - but, get right down to it, is anyone truly innocent?

Nan, that was the unfair Rule 113.

   Unfair? How so? We created a special category with a special award just for HOF members, it's a singular honor. If you can get Randy Johnson to show up at the Hurl, I can pretty much guarantee a positive experience. Nolan Ryan seemed to enjoy himself, until Larry made a typically uh, "witty" comment and got beaned. That explains Rule 79 about the Commissioner's official headgear, but of course you knew that.

    Now that you are retired and now that Clarkson, May, and Hammond are off of Top Gear, you should have plenty of time to familiarize yourself with the Rules of he Hurl (and look for loopholes),

   Good point, but don't get too excited about Ferrari just yet, in a dry race at Suzuka, barring a blow-up, it will likely be Lewis and Nico 1-2 again. Not that I am pulling for that, of course. Quaifying starts in 14 minutes...
