Yes, it's been a great resource. I still use WFRET on an old PC laptop. It's the only program I use on that computer. There is a wealth of information for instrument builders on that site.

Have been using MIMF for twenty years I think... They have(or had) the best fret spacing calculator on the planet -- WFRET; The older version (which I still have) is best. LOTS of interesting ideas and articles there.
Just stumbled across this web site. I thought it may be of some interest to some of you out there.
