as there is so little time and so many tools, i am often forced to build or modify my own.
i took a std. oscillating spindle sander- removed the oscillation function, and turned up a rub collar and use it for making risers etc with plexiglass templates.
i took a 4x36 table top belt sander, flipped it on its side- took out the old 3 amp motor and put a 3/4 horse motor on it, it needed a separate mounting setup- works great- and certainly cant seem to lug it down, grinding a bow to profile.
i would love a huge belt sander- but this will have to work for now and cost nothing.
as for bandsaws, buy as much saw as you can get for the money- that means quality , size and hp, in that order!!
i took my 16" bandsaw and put a 5 hp motor on it- i now run 1 1/2" blades with a 7/8" tooth pitch on it- its a great resaw tool- and then do finer work on the 14".
just upgraded my drum sander to a 25" model with a 3 hp 3 phase motor- hope to pick it up soon and get it working.
pretty much most of my tools are used tools, with scrounged motors and parts for upgrades- i have a local guy with a small machine shop at his house, and he turns up the specialty little bobs 'n bits as i need them.
actually i seem to enjoy the tinkering as much if not more than the actual bow making_ i know that may be blasphemous 'round here
