changing helical knives

[shanesmith80]

I'm sure I read something lately on here, but can't seem to find it.

When changing knives on a helical head, do people use a torque wrench? Setting?

I think the time has come to rotate and would like to here others tips and experiences.

cheers

There is this thread which mentions a torque figure.

and this one

a quick conversion check and it’s the same torque in each post.

There is no need for a torque wrench, just a few clunks with an impact driver will do. I have done literally thousands like this and never had any problems

I purchased a 5.6Nm torque wrench similar to this one (http://www.wiggle.com.au/x-tools-essential-mini-torque-wrench/?lang=au&curr=AUD&dest=27&sku=100277051&utm_source=google&utm_term=&utm_campaign=AU_Shopping_Negative-Margin&utm_medium=base&utm_content=mkwid|siDvftbeF_dc|pcrid|217247138095|pkw||pmt||prd|100277051au|&pgrid=45884540356&ptaid=pla-414445755006&dest=27&curr=AUD). Cost about $30. Works perfectly.
