[AT] Thanks!

I have sued them a lot, but they work better for punching if you cut the 
rivet head off with a chisel first.  They really work good for swelling 
the rivet in the sickle bar.  I graduated to a disc mower this summer 
and will never use a sickle again..  If this is a good winter for hay 
selling, I am going to get a 15ft disc mower conditioner.  However it 
has been so wet we can't get into the fields to cut.  I have about 200 
acres to cut then get about 150 acres no-tilled into oats before winter....
