boil wooden pulleys in olive oil for eight minutes to make them as hard as
copper after they dry

Well depending on the wood, that could either make them harder or
sifter. Copper is pretty soft.

another interesting one
they provide a table of circular saw speeds

formula for determining the rpm of the rim of a circular saw blade
9000/((2*Pi*r)/12)

it is pretty close for my 7 1/4 skilsaw which is rated at 5300 noload rpm
the formula gives 4741 rpm

I had to dig into this.. ;~)

I'll assume that 9000 feet per minute is the "ideal" linear speed for
cutting wood. Basically a tad over 100 mph. And that the formula is
to determine how fast the any sized blade needs to turn to cut at the
ideal speed. FWIW RPM at the rim is the same as it is at the arbor. I
think you probably meant to RPM of the blade so that the rim speed is
correct.



I use a slightly simpler formula. 9000/((3.14*d)/12)


it is pretty close for my 7 1/4 skilsaw which is rated at 5300 noload rpm
the formula gives 4741 rpm
