That rod hone is about 35 years old...not sure how I would know that.
With the larger mandrels you can hone the Detroit diesel rods. Every fall I'd get the mini con rods from the air conditioners from the TTC buses. They were an absolute pain...as I had to use crocus cloth to bring them to a mirror finish...as they used no bearings. I swear some of the king pins I rebushed and honed on that weighed more than I did. Great vid...thanks for the memories.
