Lopper sharpening
(aussie.zone)
Anyone here good with antique tools? My long arm lopper[? I want to call it a billhook] is in dire need of a sharpen, but I'm hesitant to undo the bolt without knowing how to properly retension it.
Oh right yeah, i sorta lost track of your intial question there.
I can't see re-tensioning as an issue. This is because the spring is set in two un-adjustable holes/rings. Its the motion of the handle that looks like it adjusts the length of the spring. In the picture that springs looks like theres zero, or near zero tension on it.
But as u say, i'm just goin off the pictures.
