    So, depending on how long you want to keep it, and how badly you need a toy to play in the woods or the mud, you could always swap out the existing motor for a junkyard 4L. Find an old Grand that got totaled due to body damage and snatch the entire engine out... Probably won't cost you more than...

    Completely agree, Dan. This is what I was referring to when speaking about the rude awakening that is still to come for some people. We absolutely *need* to get a handle on this thing before it overwhelms our medical facilities. 2% mortality sucks bad enough, but it could grow beyond 10% if the...

    The German Laserfreak conference was first (and is still the biggest), so they belong at the top of any list. But regarding "LEMs" in particular, we have SELEM FLEM UKLEM (Both Surfleet and Show-LEM) NWLEM Caribb-LEM TEXLEM NELEM SoCAL-LEM

    Yeah, I wish i had the 4.0. All the other Jeeps I had were 4.0, parts are much cheaper and plentiful, simpler to work on, similar power, basically everything about it was better. I bought this from a buddy a few years ago, it was a good price, and I knew some of the history, and needed a woods...

    All good points Adam and I agree, However I'd just like to highlight (not to you): vaccine != cure As they are obviously meant as a preventative measure, and at time of writing there are current ~1.3M confirmed cases worldwide; that coupled to the current trends + "odds" make for some...

    It does my heart good to see a Jeep in it's natural environment... (Cue the David Attenborough voice-over!) That being said, the V8s that they put in the grand cherokees were never as good as the 4L straight 6. Sorry to hear you're having issues with it... There was a recall on the 4L that...

    The problem I see over and over again is people not understanding exponential growth. Last week they were talking about how COVID-19 has killed more people than the 9/11 attacks. This was when we were at ~ 3000 deaths in the USA. But today we're over 10,000 deaths in the USA, and the curve keeps...

    Sold the Ranger for $800, double what I paid for it. Sold the Camaro as well, used those funds for the Toyota. Gave away the black jeep that was on blocks to someone willing to haul it away. Have one jeep left, 94 Grand Cherokee 5.2, as of this week has what I believe is an intermittent...

    I'm less concerned about the Chevy and more worried that I don't see a jeep anywhere in these pictures. Although now that you mention it, what ever happened to the old beat-up Ranger? Adam

    Been to all of these. Why limit yourself to just the US? There's also the UKLEM and CaribLEM which are both great as well as the DutchLEM that I still hope to get to someday. There was also a SoCAL LEM many years ago and there was another one planned in the Great Lakes region but, I don't...

    ... if a square size of 40x40mm (or 40x300mm) is enough -- I have some ten mirror-stripes with 30x200 or 40x300 from old kopiers, what are such "first surface" types :cool: Viktor

    You"re going to want to look for what's called a first surface mirror. Meaning that the mirrored face is on top of the glass. That's a little different from a normal mirror where the mirrored surface is on the back side of the glass. Another words, you don't want the beam to travel through the...

    Very cool! And expensive! :) I saw a picture on the German forum where you directly etched a copper PCB, what wavelenght/power/pulse rate did you use there? It looks like raster scanning, was it done with galvanometers or X/Y stage?
