Torque on forst chipper blades

[Mick Dempsey]

I've always done my TW by feel, apart from when a blade came off and ruined the anvil and pocket it's been fine!

Why not just buy a cheap torque multiplier and divide the torque by which ever ratio one you go for.

 

This one is 16/1 so you could use you old torque wrench and would still have a handy tool to undo bigger stuff without going up to 3/4" drive gear.

Haha!

 

I was amazed how little 61Nm was. I'd overtightened them for years.

 

I do them by feel, which is only a half turn more than finger-tight really. Depending on how greasy my fingers are.

I don't mind forking out the money really it's just another cost. That multiplier seems good but only goes up to 300nm. Plus simplicity is always best in my opinion. One tool for that job, less bits to loose and use.

Looks good Bob, but I'm a simple soul.

I'm going to visit my brother in Yorkshire later on this month, I'll pick up a cheaper one there.

The timberwolf 18/100 I had was even less, around 35 from memory!

Why is it then that some chippers have a stupidly high torque and others are basically hand tight? Surely all chippers flywheels have a similar rpm.

Blade/flywheel weight praps.

Ive just bought a torque wrench off eBay that goes up to 350 nm for £60.I've not opened it yet but it should be alright I guess.
