Just want to preface by saying I don't own a post hole digger -- nor do I think
I really need one -- though one sure would be handy to have. I'd probably
put up more fencing than I do if I had one.
Anyway, never used one before.. I'm talking PTO / tractor mount digger.
What I do have is:
1. access to a tractor. PTO i think is 580-600something RPM in low gear
2. a nice big gearbox, 25:1
3. an interest in fabricating a helix / screw.
Never fabricated a screw/helix before. But I've got M. Klotz's helix program and
a bunch of 1/8" sheet stock.
Am thinking might make for a fun project. However:
1. I'd be using mild steel for the screw
2. soil here is pretty rocky. not big pieces.. well.. maybe 3" at the absolute biggest
I think I'd be making some kind of boom with a pivot to hang the gearbox, then the 3 point
hitch, the screw of course, and some sort of protection from the spinny bits.
mild steel screw a bad idea?
homemade post hole digger a bad idea?
any thoughts welcomed. again, just thinking might make for a fun (and useful) project, but
I've got plenty of others on 'the list' if this is a no-no.
