Carriage Stop for a Colchester Student Lathe - part 2

In Part 1 the body of the carriage stop was bored to receive the cotter, the cotter was turned and threaded, and the bolt was machined. In this video (Part 2) I mill the slightly complicated slot to match the profile of the lathe bed, make the DTI holder and contact pins. This involves turning, milling, the shaper, chemical blackening and heat treatment. Finally, the body is given some electrolytic coating to minimise rust. Part 1 seemed to be well received so I hope that part 2 lives up the what has preceded! 00:00 Recap on part 1 and introduction to part 2 00:32 Checking the centre line of the cotter bore 01:45 Preparations for machining features at 45 deg & making angle gauge 04:58 Turning radiused corners on body 05:22 Marking out slot 05:56 Milling vertical surfaces 07:27 Bringing horizontal surfaces to final dimensions 08:56 Milling surfaces at 45 degrees 12:09 Adapting cotter 12:48 Trial fitting of body to lathe bed 13:49 Marking out and drilling/reaming/tapping holes 14:47 Turning contact pins 15:58 Turning & milling DTI holder 18:45 Chemical blackening of cotter & DTI holder 19:41 Heat treating of bolt and contact pins 21:33 Electroplating of body 22:21 Fitting of contact pins & assembly 22:51 Demonstration of saddle stop with DTI Music from You Tube audio library Last Cappuccino in Rio by Chris Haugen
