I used the same blade as on your picture.
thought is is some diamond blade but now that i think about it it really
looks not like a diamond blade.
I'm not so sure if a jigsaw is safer.
It may be harder to cut a finger off but with all the jerky up and down
movement unexpected things can happen.
(e.g. if you don't hold down the pcb properly)
If you don't lose track where your fingers are i like circular saws more,
they are more "predictable".
But you are right, the blade did cut rather good, though i never got very
straight ;-)
I see you have some guiding there, very good idea i think.
What do you think about the bearings and the glass dust?
i think the linear bearing on the piston (or tappet? what is the correct
word here?) will not last too long?
