Why do you say it doesnt like carbide? The only problem with using carbide would be excessive play in the carriage and spindle. For SS you need to take deeper cuts...slow speed..faster feed......if you try doing shallow cuts SS will work harden. The only other issue is the horsepower available....for those deeper cut it takes the power to do so. You could also try M42 Cobalt bits with high rake angles...its more forgiving than carbide...if you have the power that is.
Nice resto by the way!!
