How to mark out the birds mouth on a rafter 

Interesting Thanks Mr.Kongable👍

Thank you. I'm glad to see this triangle tool and take an idea about its usage. I really want to learn about construction, but right now I'm focusing on my millwright learning. Keep the good work on 😃👍

Great video Mr. Kongable! The speed square has so many uses!🐤🐤🐤 thanks for sharing!👍🏽

Comment for the algorithm. I will likely be doing that soon. Haven't done roofing since the 90s, but the contractors who could do my roof have terrible reviews. I could do a better job than some. Thank you Mr Kongable.
