I really get your disappointment and I was really thinking the very same thing when I ran across this video. To solve this problem I have created a channel called "Master Carpenter Series" that I'm in the process of developing where many of the complex framing situations and concepts that are most difficult for carpenters and contractor to comprehend are illustrated in plain laymen terms. I would love for you to take a look at my channel and tell me what you think of the straight forward content?
One of the goals of Master Carpentry Series is to demystify the math theory, jargon and concepts involved in the highest levels of all sorts of roof framing and designs. Our Master Carpentry Series channel is created to answer the hard in-depth with calculations and rife with charts drawn out on camera. Our Channel is created to meet and ecede the expectation of the novice DYIer as well as the Master Carpenter. We plan to provide video illustrations using mock-up showing every single cut and shortcuts in tool usage and improvisations.
We are seeking to host viewers of your calibre to give viewer participation with questions, input, shares and comment on how to improve our channel. We even want to do live demonstrations with question and answers with product reviews and giveaways.
