    Why hood blackouts?

    C'mon! In summer in Canada, the sun can often be seen above the tree-line on the horizon!... :)

    Why hood blackouts?

    Enough to blister the soft parts if you don't move them off sharpish. Got a nasty blister on the back of my arm, just above the elbow, when topping up someone else's engine oil after the car had been sitting in the 50° sun all day. Even with my aluminium chequerplate, you wouldn't want to walk...

    Why hood blackouts?

    It's not the interior temp that's the problem, it's the bodywork being so hot you can burn yourself. I kept my bonnet and fender chequerplate in matte aluminium, and it was still pretty hot in the desert, but black on those big horizontal surfaces would have been incredible. Even the black...

    Michael's new (old!) G-wagon

    It sounds like a good option to investigate. I don't know how much money I want to sink into a vehicle this old, though! I'm in the UK, btw.

    Why hood blackouts?

    The snag with all the backout stuff is... if the sunlight isn't being reflected, it's being absorbed...

    Just Playing around with the G today

    Looks like you were having fun! Aren't they great cars? What are the specs on your G? Is it full-time or part-time 4WD? And how's the 290GD in terms of power and diesel consumption? (I ask because my 300GD is dismal on both counts - 65kW, and on my first tankful, I used about 14L/100km - less...

    Increase Traction w/o a rear locker? How?

    Useful that you made that point explicitly. Torque is the "twisting force" on a shaft, and is the product of what the engine/transmisson produces, and the resistance provided by traction. Without traction, there is no torque (as would be demonstrated by putting a suitable strain gauge on the...

    Yes, it's my understanding that they never even originally intended to make a civilian version.

    Michael's new (old!) G-wagon

    Fair question. I've always liked what I've seen and read about the G-wagens. They were introduced about 10 years after the Range Rover was, and I get the impression that the Benz engineers took a long hard look at the RR when designing the G. In doing so, they did many of the things Land Rover...

    Increase Traction w/o a rear locker? How?

    I'd be very interested to get your take on how this works. I've tried to identify a coherent theory might be behind it, but previous discussions about Brake Throttle Modulation on open diffs always seem to get bogged down by people asserting that it does work, rather than explaining how it...

    need to insulate between aluminum box and framerails?

    I might be wrong about this, but I think stainless bolts through the aluminium would be worse than mild steel (in terms of corrosion to the aluminium). Stainless is higher up (bigger number) the galvanic table than mild steel, IIRC. However, of course the bolts themselves will be better off!

    GPS topos of Iceland

    A friend of mine is going there in June and I know he has some JPG topo maps, ranging from 1:250,000 down to 1:50,000. He's using Fugawi Global Nav. software on a netbook-size laptop, with a GPS puck connected by USB. Fugawi allows him to calibrate the map (pretty much any image, in fact), by...

    How is your truck set up for an expedition??

    I think that might get a prize as the most obscure, while still technically correct, pet peeve... :)

    need to insulate between aluminum box and framerails?

    The main thing is whether there will be standing water around the steel/alu parts that are in contact. If your drainage is good, and these parts are usually dry then the electrolysis will happen over a geological timeframe. If it's wet, and particularly if it's salty wet, then it will happen...

    What size winch?

    I think most of the electric winch manufacturers quote the nominal lifting (dead pull) capacity, on the first layer of cable. I say nominal, because a blueprinted winch, carefully lubricated, wired with ultra low resistance cabling to the best power source available, will pull far in excess your...

    Expedition Shovels

    Good point. A spade is more versatile, and unless you know you will only be moving loose/soft stuff like snow or sand, it's probably a better bet than a shovel.

    What size winch?

    I'm with Metcalf. You get diminishing returns from bigger and bigger winches. They get harder to handle, and are more likely to break things. Most importantly, even with an 8000lb winch, finding a suitable anchor can be a problem. At 16000 or 20000lbs, you can't just loop it around a little tree...

    How is your truck set up for an expedition??

    I think for any discussion on the value of GPS, it's worth distinguishing between the various ways a GPS can be used: 1) to give your current lat and long, where you use paper maps for the actual navigation. 2) The GPS displaying a map, with your current position indicated. 3) The GPS as a...
