Dr Drew and all. A great job! I would offer two ideas for improvement. 1) Use Photo shop or some other method to identify which hole you mean has been drilled for the c-clamp method. A novice might look at your picture and see several possible holes and wonder which one you mean.
2) Change the wording on the cocking section to make it clear which rod you are refering to at which time. i.e. the left cocking rod, which is on the right in this picture ....
I hope you accept this as constructive criticism. I think you're doing a great job with your picture trail
