Offset turning
Went to visit a friend recently who was preparing to do some offset turning. He needed to make the following part out of a pump on an old tractor. The part was no longer available. The smaller pin had broken off flush with the base and he had welded it back but was not happy with the join so decided to make it from one piece.
This is the piece to be made. Looks ok here after welding but Stuart felt the join was too weak.IMG_1484.jpgIMG_1485.jpg

Preparing the setup to begin machining. The steel bar is 2 1/2 " in size IMG_1486.jpg IMG_1487.jpg IMG_1489.jpg IMG_1490.jpg
IMG_1507.jpg I forgot to take some photos during the machining as the concentration level was high but here is the finished piece.
This sort of work is so time consuming. Looking at the initial failure, failed trial of welding, drawing up plans to machine, preparation prior to machining (cutting stock to size, marking up with a high level of precision, center drilling, loading faceplate on lathe, finding an appropriate size lathe dog, checking that the lathe tool will miss everything during machining), careful machining with lots of measuring, grinding the centre plate to size and drilling the two holes to finish. Stuart does it as a challenge and generally does not charge anything for his time. Anyway it was a good learning day for me and I really enjoyed it.
Cheers
Mark
