gv280z Posted August 21, 2014 Share Posted August 21, 2014 Wow, that thing is coming right along man. Crap, what time was it at the three minute mark? Just watching you work on those lugnuts with the cicada's outside chirping, I could almost feel the 3 a.m. delirium, out there in the garage for the last 5 hours beating on that damn wheel! Good stuff man, you should start a youtube channel and get subscribers and get paid. I think people would watch, you and your dad are a fun team to watch and you do good video editing.

devonianwalk Posted August 21, 2014 Share Posted August 21, 2014 I like at least half of the vehicles in your driveway. How's the Triumph project going? Link to comment Share on other sites More sharing options...
Slartibartfast Posted August 23, 2014 Author Share Posted August 23, 2014 Thanks! I've considered making more videos, and I like doing it, I just don't get around to it LOL. I did salvage a Fresnel lens (massive square magnifying glass basically) out of a 50" TV the other day, and I've been kicking around the idea to do some kind of "fresnel lens friday" where I vaporize viewer suggestions. Also, a couple friends and I are taking a road trip over the next couple weeks, and I'm bringing the camera. Hopefully I won't be filming side-of-the-road van repair. And I don't remember how late it was when that wheel finally came off, but it was definitely too late. More frustration than fatigue though, five bolts shouldn't take three hours. The Triumph project is still in the works. We've got a guy sending us a sample of what he thinks is the right seal material for the rear windows. Then we need to find all the window winder parts that we pulled off (five or six years ago!) and figure out how they all go back together. The most I've done recently was clean it off after a packrat or three got into the garage, climbed up into the rafters, and pissed on it. They're dead now.

Slartibartfast Posted September 21, 2014 Author Share Posted September 21, 2014 The doors close, the body is patched, the gas tanks are back in, and we found out why the driver's side lug nuts gave us so much grief. Link to comment Share on other sites More sharing options...
gv280z Posted September 21, 2014 Share Posted September 21, 2014 That is so cool. I'd like to know how to do body work like that but its always terrified me. That's one aspect of automotive work I've never had any self confidence in and drive to put any effort into is body work. Link to comment Share on other sites More sharing options...
Precise1 Posted September 25, 2014 Share Posted September 25, 2014 Looks like you guys are making good progress. Keep it up! I did salvage a Fresnel lens (massive square magnifying glass basically) out of a 50" TV the other day, and I've been kicking around the idea to do some kind of "fresnel lens friday" where I vaporize viewer suggestions. Be careful with that thing, it can be dangerous if handled carelessly; I used to make fresnel lenses, both big and small along with some co-workers. The largest I have seen made was 72" diameter... The guy who made that one placed an acrylic stamping of a 3' one in the window of his garage. The next day when he got home from work there was a burn mark in an arc on the fall wall of the garage along with a garden hose that had been cut in half, a bicycle seat that was melted and a few other such things. That was taken down, broken in 1/2 and thrown away... B 1 Link to comment Share on other sites More sharing options...
gv280z Posted September 29, 2014 Share Posted September 29, 2014 Hey guys I've got a winner winner Chicken dinner here for you, right up you guy's alley, it's a rusted out classic just dying for some attention like what you guys do, for $400 bucks. 1964 Toyota landcruiser roller with engine and tires. http://houston.craigslist.org/pts/4678427274.html Link to comment Share on other sites More sharing options...
Slartibartfast Posted September 29, 2014 Author Share Posted September 29, 2014 LOL wow, I've seen cars in the river in better shape! Those FJs have a following, though, hopefully it finds a good home. Putty has started, the wheels are back on, the tanks are back in, and we had a hell of a time starting the engine after putting the gas back in. It started right up, idled for a minute, sputtered, died, and then refused to restart. Had fuel, had spark. After screwing around with the distributor (which we're starting to suspect is out of something else) and the carb, she's a runner again, though some more adjustment is clearly necessary. So the guy who made a Fresnel lens, and knew what it was for, put it in a window? I'm planning to pick up some proper eye protection before messing around with mine, and I'll probably work some kind of movable shade into the frame as well to prevent it from setting fire to things I don't want fire set to. Out of curiosity, how do you make a Fresnel lens? Link to comment Share on other sites More sharing options...

Precise1 Posted September 30, 2014 Share Posted September 30, 2014 Not really, because it takes some serious equipment and experience. I could tell you exactly how to build a gun without it being a danger to anyone as well. So the guy who made a Fresnel lens, and knew what it was for, put it in a window? I'm planning to pick up some proper eye protection before messing around with mine, and I'll probably work some kind of movable shade into the frame as well to prevent it from setting fire to things I don't want fire set to. Out of curiosity, how do you make a Fresnel lens? Yeah, that wasn't Bills finest hour. I seriously thought he didn't think that window got good light or that the focal distance would be that far or whatever. I think he thought it would just help visibility, like these products 3M made before their patent ran out. http://www.amazon.com/CIPA-60100-Wide-Angle-Lens/dp/B000TCCWS2 In theory, making a Fresnel lense is simple as it is just a series of angular facets representing a lens curvature on a flat plane. In reality though, you need an optical engineer to calculate out the type of lens curvature you want for what ever effect (magnification, clarity, focal point, etc), then collapse that into the facets and plane (sometimes there is still a curve). Then you take that info and generate a numeric file that defines those facets in a numerical cross section (cartesian coordinates) that can be used as the body of a CNC machine tool program. The CNC is called a diamond turning machine (DTM) because it has very precise motors/controlers/axes and uses actual diamonds as tool bits. The substrate can be many things but one of the best is pure plated copper on a cartridge brass backing. Once you set up the CNC (mount, balance and face the blank, center the diamond on a rotary table, align one facet of the V shaped diamond to the face of the blank and defined the included angle of the V diamond), you spend 2-10 hours cutting the precise facets into the blank and if you have done everything correctly, and nothing goes worng, you will have a fresnel master. This can be direct pressed or used to replicate daughters that are direct pressed, usually with polycarbonate or acrylic. Angular tolerances are in the arc seconds and linear dimensions can be sub-micron; metrology equipment includes stereo and electron microscopes, white light and laser inferometers, profilometers and such. It is hard to make even the smallest, low quality fresnel in a lab that costs less than $250,000-500,000. What a small, cheap diamond turning machine looks like. A non-conventional tool set up, the curved metal nozzle is pointing to the diamond. What a diamond making a cut at 500x looks like (different set up than above). Sorry you asked?

Slartibartfast Posted October 1, 2014 Author Share Posted October 1, 2014 No, actually, that's pretty cool! And now that you mention it, I remember a friend's grandma's RV having a Fresnel on the back window. Sounds like they mount them backwards from how you'd do to burn stuff, maybe your coworker forgot that part? The Scout's hood had some stress cracking around the edges, and it was bugging me. This is actually the first welding I've done on this truck, and the first gas-shielded welding I've done at home. I already like it a lot better than the flux core crap! We'll put a dab of putty there before we paint her up, but since that won't happen for a while yet, I just smoothed it out with the grinder and shot some primer over the spot. What stress cracks?

gv280z Posted October 1, 2014 Share Posted October 1, 2014 Damn Precise, you're not just a Machinist, you're more like a Scientist. You can't just lift the lid on that little snippet of information shown there without having a vastly greater understanding knowledge of surrounding field of physics, math and science. Wtf dude. Who just built the tuner, Nefarious? You and My1Path and Nefarious should collaborate sometime on some random stuff and see what comes out of it! Holy crap.

Precise1 Posted October 1, 2014 Share Posted October 1, 2014 Thanks, but not really, I'm just a good machinist who has worked with some cutting edge equipment to take physical machining about as far as it can go. I've been fortunate to work along side of the really smart people; the corporate level scientists, PhDs and world class engineers and some of it rubs off eventually. Inventing/creating on that level is a team effort by many specialists (no one person could possibly have all the skills/knowledge required) and often requires tremendous capital and resources, probably why I haven't found a good job yet. It also makes it hard to go work for some chump who thinks he is king dip sheit of his own toiletbowl... No, actually, that's pretty cool! And now that you mention it, I remember a friend's grandma's RV having a Fresnel on the back window.

This is actually the first welding I've done on this truck, and the first gas-shielded welding I've done at home. I already like it a lot better than the flux core crap! Glad you enjoyed it. Yes, I finally remembered the name of the product, 3M Vanguard. It isn't so much that they mounted it backwards if you think about it, it is that the particular optical perscription doesn't so much focus the light as it does columate it from a fan shape from the outside in. It is also offset and truncated so past a specific angle, it will not capture any light. Think of it with way, as D being the driver and the rest are light waves. D= Here is a basic representation of a fresnel VS a standard curved lens, and you can see that if the lens were concave instead, and the fresnel facets facing the other way, they would spread the light out rather than focus it. This product diagram also explains it in application. http://www.powersportsnetwork.com/enthusiasts/catalog_item_detail.asp?catalog=7206&levelcode=48115&product=1106796&cattype=&ProductCategoryCode= Good job on the weld, that is something I have to learn...

gv280z Posted November 25, 2014 Share Posted November 25, 2014 (edited) deer.....Deer....DEER........DEER!!! Chases the deer...rofl, that's funny. Great episode man, you guys got a lot of work done, and it looks like it's none too soon either, time to plow! I can't even begin to imagine what it would be like to have that problem. You know I heard Governor Cuomo of New York today say that snow on the roofs of houses gets WET and that makes it even heavier!? I wasn't sure I heard that correctly....then at the top of the hour, the news played the sound bite again...sure enough....he said snow gets wet. How about that. Glad you got that tank running.

Slartibartfast Posted January 25, 2015 Author Share Posted January 25, 2015 Yep, if it rains on the snow, the snow will more or less hold the weight in. We had a wet snow earlier this winter that took a few trees down. The roof is designed for snow load, fortunately. Also fortunately... the Scout is back in service!
