I agree with everyone that the video needs to be concise. I have a channel also, showing how-to's, and each video is getting shorter and quicker to the point. For the new videoographers(?), look it at like a science project. State the objective first, show the steps to reach the objective and then summarize it. Don't waste time giving part numbers or web addresses because you can edit the video within YouTube to display those items in text on the screen, just where you mention it.
I love to see each person's 'secret' tips on how they do something to make it quicker or easier to build their models.
