Really like your work. Your fabrication skills are excellent. I've been a fabricator for over 40 years and am looking at the air compressor bracket and thinking that since you cut the notch for the spark plug you may have created a weak spot. How about a leg down from the front edge of your bracket to the motor mount bolt on the block. I've seen some incredibly heavy air pump brackets fail under the stress of a tight belt and the starting and stopping of the compressor. Not being critical, I'm an over builder.
