Need the formula to calculate what pulley size to use on what motor
Hi All,
Can someone give me the formula used to calculate what pulley size you need to fit to a motor to drive a small bench saw?
I picked up a very well build small steel bench saw, fitted with a 9" blade and it needs a motor.
I was thinking of using an old washing machine motor in the 1/2 to 3/4 hp range - depending what my local washing machine service centre has out the back:D
Details of the saw are -
Top plate is approx. 6mm steel. Pulley is 60mm diameter. Blade flanges are 75mm diameter. Body plate of saw bench is 2.5mm steel. Overall dimensions are 355mm(high)x500x560 mm.
Blade is 235mm diameter, has 30 teeth and is TCT (TUNGSTEN CARBIDE TIPPED). This is a good configuration for precision cutting. Blade bore is 25mm. Blade lift mechanism (see image) is very smooth but with no slop (as are all moving parts) and can be operated with one finger.
I will be using it to trim pen blanks, small boards for boxes and cutting samples down to size for my sample collection. The pulley on the blade drive shaft is 60mm in diameter and I need to know what size pulley I should put on the motor. See photos below of the unit.
