I do not advocate the need for a complete machine shop. The most common tools used in most projects were a good set of ratched wrenches, a multi head screwdriver, an electric drill, brushes and a skillsaw. The project got through most of the time with these tools. However, I do want to emphasize how some specific tools were critical in executing fiberglass related tasks. All of them significantly decrease the execution time.
4.1 An Oscillating Saw
This is a must have. The oscillating saw helps in cutting fiberglass, wood, epoxy, cake or pretty much everything you put in its way. I am not a medical expert, but this thing may even cure cancer.
I just cannot imagine how to cut between layers of fiberglass without one. If you can afford a model with a built-in aspirator, even better.
For the anecdote, an oscillating saw is called « outil oscillant » in french (« oscillating tool »), which is so general that it could also describe a vibrator. If you are alone and need to work out a tight spot fast, this tool will give you a good hand.
4.2 A Dremel Kit
This tool is helpful for little nasty tasks that are too small for a grinder, a sander, or a normal drill. I already had one and its use grew on me as the project evolved. It is not a must have, but it is very useful.
4.3 A Grinder
With disks for scrapping and cutting metal, this is a must have. It speeds up all the work related to prepping fiberglass. In comparison, I almost never used a sander.
A grinder is a powerful tool and it should be used with caution. It was always used with a mask and protective eyewear.
