OK guys,

I am looking to put a centrifugal clutch on the dimension saw I am building and think I have it worked out to the Noram 180009. My engine is a 17hp Briggs Intek twin with a 1' output shaft. So the Noram with its double 4" vbelt sheave looks like it will fit the bill, but at $265 is pretty expensive.

Which brand / type / size / hp centrifugal clutch is everone using? (Homebuilds or professionally built units doesn't matter...)

  There's only a couple available that will stand the hp, and they cost about that much. I haven't seen a homemade one, but it would be fairly complicated to do. I'm sure some could, but the bought one may be more cost effective in the end. My output shaft is 1.25", 23hp, and I think I paid over $300. For a Peterson WPF swingmill. Can't recall just what model clutch but I remember having to spend some time finding one that would fit the bill.

Why not use an electric clutch? They are readily available that will handle 25 hp. Think riding lawnmower parts...

Here is the company that provided the clutch for my first Baker Sawmill.

Pitot,you could have a rocking base on the engine or a belt idler to tighten the drive belt and keep that money in your pocket. Frank C.

Well that's two votes for BLM, and I see on their website that they are Canadian Manufacturer. I will definitely check them out!

Frank, I guess I'm just not that big of a fan of clutching with the belt. But I do agree, very cheap way to go!

There is definitely nothing wrong with clutching with the belt.  There has been many a mile of wood sawed by doing that.  :)

A neighbour of mine has an electric clutch on the cutter-deck drive for his ride-on mower. The one thing I have noticed is that it's like a light switch.....on or off rather suddenly. When the deck engages there is one heck of a thump as the drive cuts in. I wouldn't think that sort of shock would be much good for the band blade. If the engagement could be done with a "soft-start" gizmo loke on most big power tools letting you ease the power on......That might be a good thing.
