Bob, are you saying you cut that Woodruff keyseat by hand with a Dremel? Nicely done indeed.

Hi Bob , I like the drive dog idea, its looking smart are you still going to make it cam lock type ?

Cheers Mick.

hi hawkeye yep made the first cut with one cutting disc so i cud line it up with watt was left of the key way in the shaft then put 4 cutting discs on to the arbor then with a stone dresser dressed them dawn to the diameter of the key then with the shaft in the vice just feed the cuting disc in its up in the air at the moment mick i wood have to machine the bolt hole flat to give me the height clearance but this will leve the base where the bolt gos threw rather thin i have seen a other type that uses two cam washers to lock the tale stock but will still need to machine the base of the tale-stock
