What is your favorite episode?greenspun.com : LUSENET : Junkyard Wars : One Thread
(This isnt counting the Jan 3rd episodes) My fav episode of Junkyard wars still has to be the Demolition episode. It was SOOO COOL! I was rooting for the Muncher, It sucked that it had to break, that machine could have left the B-Boys in the dust! What is your Fav. Episode?

My Pavorite JunkYard Wars Episode is the Flying Machines!

Only been watching a short time, but I would have to say the amphibious vehicle episode where the bikers nuked the naval engineers. Does anyone know if TLC is going to replay the first season, I haven't seen it yet. I agree the host for the American version is awful.

Steam cars. Yes, boilers and engines were planted, but bodging everything together for a very entertaining race was fantastic. Team personalities really helped make it interesting.
P.S. On the first two american JW shows I didn't see either team making a single calculation, more of "throw it together and hope". I have to agree with the Nerds style!

Gee whiz, didn't you notice my on board calculator, the one between my ears, it was working during the entire show. I know it's a little rusty but it still works rather well. Heck I can still use a slide rule! JustJay

With age and experience, guessing tends to get a little more accurate! A WAG (Wild-Ass Guess) becomes retitled "Engineering Judgement" -- and actually tends to be pretty close!
I did wonder sometimes if Geo was calculating things just for the sake of understanding, without any effect on the final machine. However, if it is considered a science education show, that's wonderful. If it is a game show, they can safely edit those parts out.

Gee.....were do I begin.. The Demolition Machine was great..as was teh amphibious thing(can't remember the title on that) Not to Mention the Dragster(U.K. Version) I think my worst episode had to be the One where they had to made radio controlled Bombers. Is it me or was the Rev's extremely annoying. I think the Expert was even getting anoyed cause it looked like he was doing all the work. Favorite team was teh Beach Boys cause they had a great sense of Humour. Hope to see them Again. The Nerds Were my second favorite..Though I kinda felt sorry for Jeff....the other 2 seemed to keep turning down his ideas. OK....enough of my thoughts...whats everyone else think?

Muncher is the one machine I wished we got to build.
You didn't get to see a lot of the jokes we played. When I put the propellor on the nose of the Nautilus, I told robert that it was to arm the warhead. Since they didn't want to say that we had 24 volts inside the hull, you didn't get Crash's little ditty: "Twinkle Twinkle little star, Powere equals I squaredR.
We had a for-sale sign that went onto the loosing steam car. (and there was that bit I cooked up with the dictionary, which they did use.
We yanked hard on the Brothers leg -- You saw a little bit of it in one of the commercials, but not in the program itself. We discovered that chocolate around 3 was a wonderful thing. So we decided to share. I bought some extra, and a parachute -- Over the wall it went, with a shout of "INCOMING". You saw, in the commercial, the brothers response (kneepads).
Geo is difficult. His on-camera apperance roughly matches his in person. Crash is much nicer than they used on camera. I had to put the team together in a very big hurry, and didn't know just how Geo would be. I want Crash for next year, but Geo is a hard decision. (oh yeah, they hide it well, but I am the actuall leader of the team. Crash is a faster designer, and I a faster harvester, so thats how the assignments were made.)

My take on the calculation thing about launching pumpkins is that it don't make much difference, unless you can use a sabot, and plenty of Mayo. At that point it starts to add up, and work with some sense of continuity. The flat pumpkins would have been almost impossible to launch without having the sabot, as you saw in the 2nd and 3rd practice shots, where the bucket and pumpkin turned in the barrell. With on line friends, we have calculated the terminal velocity of watermelons and bowling balls at about 250 mph, and measured it with melons, using video at 286, which isn't too bad for guess work. My team holds the world's record for human powered pumpkin launching for range, a whole different game than for accuracy. As Bill "Broad Dog" Thompson, the Judge said, "Mother Nature controls the pumpkins". We expected that the treb. would have a better chance of dunking one, and with us shooting first, we were going for the dunk shot. The three rounds fired in the competetion were all at the same pressure. Bill said that from where he was, on the tower, you could see the pumpkins trajectory curve as it was falling in the wind like a flat frizbee. If you notice the flags in the vid, the wind was blowing off the beach, and over the levee, where we could not tell how much wind there was aloft. Looking back, we would have done well to shoot level, but we didn't. It would have been nice to have done some calculations about the compressor gearing. Had I known that we would only need less than 25psi, we would have turned the tranny the other way for higher compressor speed. Our world championship shot of 1334 ft was fired at about 48psi, using a scratch built compressor made from a recumbant pedal exercize machine with a three sp bike hub, chain driving a 115lb, 36" dia flywheel (from an antique printing press), a Toyota four speed, a Dodge(not the car brand) 24/1 reduction box, a home made three throw crank working three 4" bore X 36" stroke air cylinders with modified poppet type check valves at both ends of each for six strokes per crank rev. It will easily pump to over 125psi,which is as high as we have tested it. It pumps almost 3,000 cu in per crank rev. It's a B to pedal too, as you only have two minutes to input energy into the machine for the WCPC competetion and you have to really put out. We put all the gears in it so that you could pump volume, then work down to pressure. The first fifteen psi takes about thirty sec, then it is uphill and downshift from there. A bladder tank with a ten inch discharge is the next big change. We didn't have time to work with the compressor on the show much, as we were already near the end of the build day when we got it, and we didn't know what the bore and stroke was anyway. We could have tested displacment with water, but didn't have time to mess with that. In the end, thanks to the double bucket and styrofoam sabot, we made it work . The styrofoam was stacks of actual artillery wadding that we picked up where they had been testing at the mil. base, all taped up with redneck ribbon into cylinders, and stacked between two buckets to make the sabot. If the ailens ever come up with a zapper that makes all the duct tape in the world let go at the same time, they will have us powerless to defend ourselves.
