Re: [ATM] Quandry over steel washer tool

[Dale Eason <atmpob@yahoo.com>]

You should start with something like a pipe flange to
do the hogging.  That is what I did on my 16 F5 plate.
Then after you get the curve pour a stone tool and add
the washers.  I used US nickels.  They are cheaper
than washers.
