A Harrison M300 lathe tailstock modified for lever operation. This is a spare tailstock, the original being retained for heavier drilling.
The tailstock was modified for lever operation to allow for faster use especially when drilling deep holes as it allows far faster entry and exit from the hole than the standard tailstock with screw operation. A nice benefit is the improvement in feel for what is happening at the cutting face.
The tailstock quill and casting are unmodified so can be reverted to standard if required.
A small modification to the depth stop where the M6 cap screw in the single split shaft collar was replaced by a M6 cap screw cut down and threaded M6 below the head and a short spacer added to take an indexing lever clamp to save having to find a suitable Allen key whenever the depth stop needed setting.
