Building a New Lathe
awemawson:
Many many pre-war (I mean 1939-1945 war) models of engines etc were made with very basic tools, the lathe often being treadle driven, and the models were of a very high standard. When I was involved with the SM & EE I was amazed at the workmanship of some of those early models in their collection.
To have a milling machine in a home workshop was unheard of, but vertical slides to mill on the lathe were not uncommon.
I agree Steve - making things with limited resources demands imagination and determination but it CAN be done :thumbup:

Done with the clearance hole. Now starting the bearing journals.
I believe these need to be 2.441" in old measurement. This is going a fair amount easier with only an inch to bore for depth. The arbor mount cutter is working very well. Glad the other is over with! :Doh:

Getting closer to journal size, it was time to make a bore gauge. I found a scrap piece of aluminum 2.5" in diameter. The bearing measured (on my calipers) 2.4395". Not that they are accurate to a half thou, but I've been using it consistently, so parts should match.
vtsteam:
I turned the gauge to 2.440" on one side and 2.430" on the other. Sorry I don't have any photos of turning, but if you're interested, John (Doubleboost) posted a fine video on youtube awhile back showing the process of bore gauge making (his ER32 lathe chuck video).
I'm adding an additional touch to suit my particular headstock boring setup here -- first drilling the gauge 3/4"
vtsteam:
Then I sawed a slot close to the finished diameter on my bandsaw. I probably could have left it there, but decided to clean up the slot on the mill:
