I am using this old Champion Tool Works lathe built in Cincinnati Ohio. It has a chart on the quick change gearbox for different thread pitches. It has an 'IN' position with options 1, 2, and 3 then 'OUT' position with the same options. I figured out the lathe is presently using number 2. I found the in and out shifter. I cannot find the 1 or 3 setting. The lathe has 2 different ways to get 8 threads per inch. I need the number 3 setting using the out gear or number 1 setting using the in gear. I have attached a couple photos of the lathe. I fear it is missing a couple extra gears for the 1 and 3 settings. Could someone familiar old machines tell me where 1 and 3 setting is and if they are missing gears, how many teeth do they have. The only other info I have on the lathe is it has an 18 inch swing.
Thank you hoader
