There are probably a dozen ways to do this but everything that pops in my head seems clumbsy.
I'd rather not have to weld anything.
I've got a 'claw' digging tool fastened to the other end of a 10' conduit and I'm intending to dig a horizontal hole through some clay.
The force that will be applied will be roughly what an old guy would apply with handles on that tool.
My current inclination is to just keep joining successively smaller pieces of pipe until one will fit in the chuck- then pin them all together.
Any better ideas?
Thanks, Jim
