Hobby,
I am not trying to piddle on your parade, but build posts just made up from youtube movies and music don't seem to attract much attention, mainly because of three major problems.
The first is that people need to watch the full set of four before they can glean what is really happening, and in your case, most probably over an hour of watching time. A rather long time if you are not really interested in the subject, but hope to learn something that can be used elsewhere.
This gets onto the second issue. People want to learn from your post, and by doing it the way you have, they cannot ask intermediate questions about what you are doing, such as what type of layout fluid, type of machine and cutters you are using etc, etc. or maybe suggesting a better way for you to carry out a certain machining operation.
The third issue is that because there is no voice over, then a lot of people, especially beginners, won't have a clue about what you are doing, except that it is a model scissor jack.
