Glass meets stone.....Didn't see any question about opinions from the op, just a post on work done..................if it is't your taste wouldn't it be better to keep your opinions to your self rather than belittle someones work............
Taking a leaf from your book i guess it could be said, that vid could be 1/2 as long, or less if your arm wasn't in the way 1/2 the time, and the point would still be made.Using an adjustable monkey wrench on splines is a big no no.
