Wrong section of the forum, as it is not discussing Model Engineer magazine, as you seem to post video links like this quite often then I would suggest they go into "Workshop Techniques" for ones such as this I will move it now.
Can I also ask that you are a bit less cryptic with your thread titles as without clicking there is no way someone can tell what the threads are about, had it been titled "Mr Crispin Videos – getting technical" all those who already know of his work could have passed on it if they wanted to.
