150 FT Pound Torque Wrench..

[gwbutler]

Hello all,

I plan to replace the left-front axle on my 88 5ksq this week end.  The 
Bentley specifies 207 foot pounds as the torque spec for re-installing the 
axle nut...and I only have a 150 foot pound torque wrench.  I priced out a 
gorgeous 250 foot pound unit at Snap-On ($200.00) but due to the infrequency 
of use I suspect it's an impractical and dangerous strategy...my wife would 
kill me.  Any BTDT's on using a pipe as an extension...?  TIA

Regards,

George B.
