Saw bench clutch?

[Gmorgan]

Morning all,

 

Im in the process of making an engine driven sliding table saw bench,

 

Ive got the pulleys, belts, tensioner, engine and drive shaft/spindle made and fitted but its just occurred to me - will i need some sort of clutch on the pto from the engine instead of an ordinary taper lock pulley?

 

Im just thinking when the engine is switched off, would the blade stopping suddenly affect anything? Ive never used an engine driven one and i haven't got one i could go and have a look at to see if they have clutches fitted.

 

Thanks

Well my pto one had a foot pedal. If something got stuck youd press pedal which would move a roller / pulley away from the belts and backing tension off so the disc would t spin.

 

Can you not do something similar principle

So am i correct in thinking the clutch is there purely for if a log/nail e.t.c jams the saw blade?

Hi had a few saws over the years never had one with a clutch on it , the one I have at the moment is a old macconell towable one with 10 HP Petter twin on it pulley on end of engine crank shaft belts up to pulley on blade shaft if I give it to much to cut and blade gets stuck (only happened twice in 8yrs tho) the belts just slip on the pulley's.
