Why don't you redo the CHB Lathe in metal and get rid of the resin parts?? I know you can weather it to match the other machines, but it still doesn't quite match the others. Even if it were more expensive I don't think you would have a problem selling them.
the bed and feet are cast in resin and it should be no problem to match up the finish with the metal parts. Brommer had a heck of a time casting that bed and my high temp metal was even tougher.... not a matter of cost there J - a matter of time since the yield is soooooo low.
