Well then, how does one cut curves in aluminum and steel plate?
One wold suppose the minimum radius would be a function of the
width of the blade, how tight a curve could be cut with a 1/2"
blade?

Personally, I would multiply the radius they give, by 2x, when
cutting
thicker steels. Shrug Too tight and you tend to burn out the set of
the teeth.


OK and a tighter radius convex curve can be cut by taking a series
of cuts tangential to the curve followed by a bit of grinding.

Indeed. Which increases your production time dramatically.

which thinks that nothing is worth war is much worse. The person who has nothing for which he is willing to fight,
nothing which is more important than his own personal safety, is a miserable creature and has no chance of being
free unless made and kept so by the exertions of better men than himself."
