Excellent job as always. Clear, lucid explanation of the design choices and the work flow path. I very much liked the inclusion of a land to ensure the clamping load is correctly distributed. I enjoyed your film very much.
Hello Clive. I do like that you use traditional tools to measure and scribe your work pieces. As always, excellent work, clearly described and expertly accomplished. 👏👏👍😀
Hello Andrew. Perhaps the main reason I use traditional tools is that I don't have such equipment as DROs etc! Anyway glad you get something out of the videos.
Somehow I had missed your tailstock video. So I just watched it! Interesting that your lathe had an aluminium alloy cotter. As usual you got a good result in a fraction of the time!
Is there any significance in 47* degree angles. Versus say 45* degrees? Do you think there is any chance of deforming the 2.5" cast iron bar. Clamping it with angles instead of a radius. Or is that too pessimistic?
Ah yes, it does seem a bit arbitrary! The angle was derived from the geometry - specifically tangential contact on the bar at the middle of the female cotter. I haven't done any calculations but I doubt the cast iron will permanently deform before the cotter yields. Of course everything is subject to elastic deformation.
Nice job however my OCD kicked in when you didn't true up the centre hole for potential rework😅. Looking forward to the boring operation of the lower support arm bore.
