Parting or cutting off steel has always been a challenge on my lathe.
Issues range from heavy chatter to broken inserts and tools which end up stalling the motor and sometimes damaging the work done on a part.
Today we're making a solid tool post mount to replace the compound (top slide). The compound on small lathes is known to have rigidity issues and that's what we're looking to upgrade.
