A lot of the work is grinding and fitting of metal and there
are always flying particles of metal so you might consider
doing most of that kind of work outside with proper safety
gear on.
Some Tool You might want to rent:
Some of the tools you will only need for a day and may never
use again, so visit the local rent-all place and get a list of
what they have available.
I would say that engine hoist falls into this category. I would
rather rent this tool for $20 per day than buy one for $300?
A hoist is very handy for lifting the engine, or any heavy
object and for lifting the quite heavy DC electric motor into
your new electric car too.
Remember to use your hoist for all heavy lifting.
