RARSfest

Post by Andrew Robinson » Thu Apr 18, 2019 10:23 am

RARSfest is coming up this weekend in Raleigh NC. While not Fusor related, ham fests are always a great place to look for odds and ends that can be used in pursuit of a fusor. I'll wait for Richard to respond at length on this subject. I'm sure he has LOTS to say about both RARSfest and ham fests in general. I know Richard and few other Fusor.net members show up each year. I'll have my usual table setup. Hope to see some of you out there.

Yes, this will be year #28 in a row for my attendance at RARFEST. I Would not miss it. It is the farthest south I will go for a hamfest just outside my 130 mile circle radius of hamfests I will attend. It is worth crossing that circumferential line as they always have cool stuff that tends to never wander as far north as the Richmond hamfest.

See you there......

I found and bought a lot of small stuff.

Bags-o-bolts 50 Allen head 1/4 - 28... 1.5" & 2" bolts ... $2 each bag full. (conflat bolts for 2.75- inch flanges)

2- TFT arduino displays with library software on CD. $10 for both

12- various radio shack, new in blister pack, 1200mah, Li-ion, 7.2v, flatpack, Blackberry batteries found in a huge box of ex-RS stock... 50 cents each

1000 proto board gold plated 1-inch long pins in an unopened box $15 (for making up really nice jumpers for proto boarding.)

5- 3 foot long, slender shrink tubing for the pins above $2.50

10 reels of Kynar 28 gauge wire for $1.00/reel! Wow!!! Most reels were over 1/2 full 500 foot reels. Two reels were full and never used. One reel was half full, 250 feet of silver plated 28 gauge, milky, see-through plastic rated at 1kv insulation. I went for various colors. I had to take these to the car as they were bulky and heavy. I then returned to the fest.

2- Weller 75/100 watt guns (no tips) $2.00 each. I found the copper tips at another seller for $1.00 each. They worked when I tipped and tested them, once I returned home.

1- Large three armed WW-II 860 tetrode, vacuum tube... NOS in packing $25.00. I might make a small induction heater with this tube.

My super buy of the entire fest was a classic, made in india, putt-putt boat. They were just as I remembered with razor sharp, sheet metal, exposed and ill-fitted edges. (new manufacture) $5.00 ....discussed in these forums in the past. Lost childhood regained.

Three nice stepped cone ceramic insulators, diamond bits for dremel tool, 1 radium dialed WW-II tuning meter, etc.

Typical wonderful fest, chatted with Andrew and a couple of my old UNC nuclear engineering dept. buddies. (bought a few NIM bins and modules from them in the past.)

Very nice.
Is the fluffy stuff under the tube just its padding from the original box?
Reminds me of a pile of fur along my way to work, that was a road-killed coyote a couple weeks ago.

Looks like insulation for thermal purposes.

Most all vacuum tubes of some size were packed in this weird stuff during WW-II. I have three WW-II, NOS boxes with 304TL tubes in them and this stuff is packed in all of them. I can't figure out what it is or what it is made out of, but it is nice stuff. Soft as cotton, tough as nails to tear, but cuts easy with a sharp knife or scissors.

I know all the super old hams, (70+), here have encountered this stuff at hamfests when snapping up really old WW-II surplus items in their original boxes. Many instruments, etc. were also packed in this material. (Bob)? I am super old by any standards... 73.

I know the stuff you mean but I can't think of the name of it.
The more reactive the materials, the more spectacular the failures.
The testing isn't over until the prototype is destroyed.
