·Hi Goldnut&friends I often wondered if a timesaver machine would sand the gold off of boards that were would require a good dust system to separate the bad dust from the gold dust A "timesaver machine" is a trade name for a machine made to sand off burs and finish plates and pieces of metal to a sanded finish I believe those
