[TheForge] Little Giant bottom block shimming problem

[Doug Ayen]

I'm having a problem with my 50lb Little Giant: in use, no matter how I
try to use the wedges and shims that seemed to work well with the previous
owner, the bottom block keeps loosening up and falling out.

Can anyone suggest a web site or other documentation that may assist me in
figuring out what I'm doing wrong?

The current setup, which is how I got it from the previous owner, uses 
two opposing wedges with some copper shims between them on one side of the
die, a single thicker wedge on the other side, and a support plate about
1/3" thick underneath the die. There is what looks like some significant
wear on the dovetail on the base block portion of the hammer, but the wedges
and shims seem to make full contact on the bottom die.

Any suggestions? I've tried cleaning everything (it was coated with
grease and oil) and it stays in place longer, but will still work its
way out inside of 10 minutes of use.

Thanks.
