It would be fun watching the wind do the work,
Let me reword that....It would be fun watching the wind do the work of dulling my hacksaw blade!
Seriously 'tho.........
Okay in my zeal I forget the little details that I learned and are common practice for sawing with a hand hacksaw which like you reminded me is more than just a simple back and forth motion...which reminds me of a Lindsay publication on how to make a machine operated hacksaw which provided for the lifting of the blade on the backstroke and downward pressure on the forward stroke.
Also seems like it had a means of oiling the blade.
Thanks for reminding me.
