[AT] Thanks!

[Dick Day]

I bought one last month, just before my back surgery.  I could not even bend 
down to "look" at a section, much less replace one :)   I found mine at the 
local f&r store for $49.  This winter, it will definitely get some use.

One of the advantages of the rivet spinner tool is that you can change
the section(s) out (in the shop or in the field) without removing the
bar from the mower, you don't need a hammer, chisel, special punch, or
supporting block - just a box wrench to  run the two tools down. One
tool punches out the old rivet, and the second one supplies the pressure
to set the section securely in place against the bar, then puts pressure
on the rivet to enlarge it, and finally round the end to produce an even
surface that won't catch on anything. As they say in the ads: "try it,
you'll like it".
