    Gas diffusion - a question or two

    dave9, thanks for that. It sounds like an easier solution than I've so far proposed. The inner ledge of the sash is about 28mm (1 1/8" ) wide, so I could easily run a router along that and carve out a nice clean channel (maybe 3/8" x 3/8") and fill it with desiccant. It's pretty dry in our...

    Gas diffusion - a question or two

    Thanks, guys. Steve, I take your point about the expansion of the argon from external heat (sun). But I wonder if the expansion might be countered by the ability of the perspex to bend (bulge)? Re desiccant, once it had absorbed its maximum moisture, wouldn't it be effectively neutralized...

    Gas diffusion - a question or two

    This forum may not be the place to ask this question, but there are some extremely knowledgeable folks here, so here goes: I'm planning a little DIY double-glazing project. This will involve several opening windows (we call them 'sashes' in NZ) which currently have a single layer of 4mm...

    I want to modify my car radio

    Guys, thanks for your comments. It's obviously way more complex than just inserting a headphone jack into the speaker output, so I'll flag it. Obviously there are more expensive options than a $2 headphone jack and a smidgen of solder, but it's not important enough to me to warrant the elevated...

    I want to modify my car radio

    My hearing isn't the greatest and I'm not hearing my car radio\disc player properly. What I'd like to do is add a headphone socket to the radio unit so that I can choose to listen to the speakers normally, or through headphones. I've been told I'd have to modify the radio to do this. I'm no...

    Loud music from over-the-fence is causing offence...

    Thanks for your comments, people. However, as I said earlier, I've already tried most options. I've had a few beers with the 40-year old unemployed ex-con father of the three teens that live with him. (There's also a daughter's boyfriend). I've fixed his computer, refusing any payment other...

    Loud music from over-the-fence is causing offence...

    After recently becoming somewhat broke, my wife and I were forced to settle in a small town in a very Wild-Westy part of New Zealand: Deepest darkest Southland. Like many of the inhabitants of this hillbilliyish community, our hard-smoking, hard-drinking, benefit-frauding 'neighbours' on the...

    I thought I needed to post my question elsewhere? As I asked.

    Car battery jumpstart gadgets

    No, Steve. Thanks to those who have contributed useful information, I now have a clear understanding of the formidable technical and economic issues that currently prevent the construction of a cheap and simple mains-powered, battery-less jumpstarter. Actually, there is something else. I'd like...

    One of the things that gets my goat on bulletin boards is that people rarely read your statements properly before rushing into print. On the credit side, I now have enough goats to start a cheese factory.

    Is it my imagination or is kellys_eye a global-warming denier? Or, to put it more kindly, just a skeptic? Personally, living close to a major stratospheric ozone hole (which has begun to heal, thanks to the 1987 Montreal Protocol), and seeing the steady rise in NZ atmospheric temperatures over...

    Well, actually, I was taught the correct method. If you re-read my post you'll see I didn't say that I was injured in this way, only that this type of injury wasn't uncommon.
