Had to make a quantity of bushings for a piece of farm equipment. Stock is turned & ground round steel bar. All manual lathe, no DRO. Bushing length tolerance is +/-0.010", ID tolerance is drill bit tolerance (no boring/reaming).

I got into a rhythm making them. Use parting tool holder at 0.000" as a stop for material, kick lathe on, drill hole, deburr hole, roll carriage over to stop, part 80% through, back off and run a file in the groove deburring 2 edges at once, finish parting, turn off and run carriage back to 0 to slide material out to stop point and repeat. This left only 1 edge (inner edge from parting tool on the parted bushing) for manual deburring. I got in a rhythm and decided to time myself. I averaged 1 min, 25 sec per part...add about 40 sec each for manual deburring of the remaining edge and I did ok. Dealer wanted $7 each for the bushings. Taking material costs out put me at about $180/hr for my time.

Not bad for a Sunday afternoon in the shop with a fire going, kids playing out in the sub zero weather coming in every 10 minutes to sit in front of the fire.
