Right 2 Pictures - If you have a hole with slightly damaged or dirty threads and you do not have the correct tap you can make up a cheap thread chaser from a bolt of the correct size. Using a file you can cut a longitudinal V channel at the end of the bolt. You need to ensure that the 90 degree edge is leading in the direction of travel. The back edge of the travel gives the chips somewhere to go.
Left Picture - Sometimes when mounting accessories with multiple attachments points it's a real pain to get a few of the bolts started if things don't quite line up. I trick I use is to thread a nut on the bolt & grind at least a 7mm long taper on the end down to a dull point. (a new longer bolt may be needed). Thread off the nut. Now when you insert the bolt, push to help align it with the hole while turning.

Being in the machinery business is really exciting. In my line of work, I get to do a lot of experimentation, especially when it comes to equipment and parts. I have a lot of experience about the concepts of machines and how to tinker with them, however, most of what you have written here are new to me. I am really glad and excited that despite my age, I can still learn a lot. I hope that I can improve my work.
