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.
Rust:
High heat (like a flame torch or burner) can help, the uneven expansion can crack the connection made between the two rusting metal surfaces, in this case thats the bolt and nut.
WD40 can also help, but make sure its dried off before applying heat, otherqise you'll be starting a fire.
Hammering the bolt side can help crack the rust, but in this case due to how weak the metal is, i don't know that this would be a great idea, due to the risk of deformation.
