fretless guitars

[Jon Grant <tianmus@aracnet.net>]

        Jeff Collins mentioned  someone named Bobdog fitting a "stainless 
steele board" onto his guitars to make them fretless.  Can you enlighten 
me as to this procedure?  Years ago, when I wanted a fretless, I just went 
out (on the advise of a very respectable guitar tech/luthier) and bought a 
set of good quality metal files, then set about to filing down the frets.  
This took forever, and resulted in a sore arm for a few days.  It worked 
beautifully, however, and I'm still enjoying the guitar.  For those for 
whom cost is an issue, the files cost me $15 Canadian.  As long as you're 
careful not so damage the actual wood on the fretboard, everything should 
be fine.
