    Oops - I missed the original explanation in his post and I rescind my objection. Thanks for pointing it out George and feel free to continue on with the caps.

    Putting some grip (stippling) on an aluminium drive pulley.

    My thoughts exactly on this topic. I've been away for a few days and cam back to another 2 pages of replies on this thread! I was specifically referring to your contributions to the topic. Specifically, your post numbers 11, 14, 17, 18 before finally mentioning safety in post number 22. I was...

    ??? Making Setups

    The internet archive is full of materials well within copyright and the legal opinions suggest it is, in general, in breach of copyright. The problem is, they vigorously defend copyright claims and each copyright holder has to launch their own actions. As you can appreciate this is extremely...

    Putting some grip (stippling) on an aluminium drive pulley.

    Supposedly the North American vehicle fatality rate is 1.16 per million miles but with vehicles in autonomous mode it falls to only 1 per 320 million miles. So the car would have been less safe with a human driver - and driver fatigue is a huge factor in many fatalities, so a tired driver would...

    Putting some grip (stippling) on an aluminium drive pulley.

    This type of reply is my main issue with this thread. It's an obvious personal dig at the original poster, and any others who don't agree with your view, which is composed with such fervour that you couldn't even get the OP's name correct (it's Jim, not Steve). Yet it does not add anything to...

    Ceramic Gas burners on Locos

    This is overstating the risk and being alarmist in my opinion. Obviously too high a concentration is very dangerous but there is a threshold where damage starts to occur and we are all routinely exposed to at least some CO as a product of almost all combustion processes (including the humble log...

    Chinese Vertical Hit and Miss

    Not sure where you got your information from but checking the WD-40 official website suggests it is not accurate in terms of lubrication effectiveness and corrosiveness. From the website itself "WD-40® Multi-Use Product is a unique, special blend of lubricants. The product’s formulation also...

    Chinese Vertical Hit and Miss

    I use normal petrol (robbed from the lawnmower jerry can) with about 5% WD40. Seems to work well although some don't like the smell.

    Ignition System for model Hit and Miss?

    The RCEXL clones I've used do have automatic advance though, which can make it hard to get the timing right for the first start. Turning the engine over slowly by hand throws a spark at a way different place than when the engine is turning at running speed. They still work, it's just a trap if...

    Putting some grip (stippling) on an aluminium drive pulley.

    Absolutely the 'Hitler point' is a hard limit! Although I'm hoping we're respectful enough that it won't come to that...

    Putting some grip (stippling) on an aluminium drive pulley.

    Nothing to be sorry about. I skimmed the video (it's a bad habit I have) but I have since gone back and viewed the relevant bits to make sure I didn't miss anything. I agree the force was being applied in the weakest direction of the tool, I don't agree on the name of the tool (because we call...

    Putting some grip (stippling) on an aluminium drive pulley.

    Joe Pie has a video on filing in the lathe and has some very interesting demos of the file touching the chuck and (usually) being ejected rather than grabbed. Personally, even though I love most of Joe's videos, I don't like his practice of filing with his left arm over the rotating chuck. In my...

    Putting some grip (stippling) on an aluminium drive pulley.

    But if it wasn't the tool that he used that you have an issue with then was it simply the practice of hand-holding tool on a metal lathe? There are plenty of videos of graving and metal spinning where they do just that and no-one suggests these videos are not appropriate. What exactly is the...

    Where to buy acrylic sheet in the US?

    I can't help with a supplier name (as I'm in Australia) but when I needed some I looked up the closest commercial supplier and took a drive to their shop. They weren't set up to sell to the public but they were happy for me to go through their skip bin and it was full of off-cuts and 'scrap'. I...

    Putting some grip (stippling) on an aluminium drive pulley.

    I'm also struggling to see what people are getting so worked up about here. The 'cutter' was being held in a pair of multigrips (which I often trust enough to do various jobs involving molten metal work and have a far more reliable handle than a wooden leatherworking tool) so hands were nowhere...

    Hello and it's time to build something

    Your castings should be good to go without any ageing. I got some a couple of years back (different source and different engine but still applicable) that were rushed to me straight from the foundry and never had an issue. I've also cast the odd piece myself in the backyard and sometimes gone...

    Back to work on my UFO

    I've only ever done the torch heating also - it was the first way I tried and it's always worked out well (so far...).
