Thank you, the tapers were difficult because I do not have a way to measure exact so I glide the cutting tool along a good side until it matches. I recorded the angle of the tool post, but found I wrote down the wrong number when I got to the flywheel and had to do the angle check over and some slight adjusting with the lapping.
I think the angle is near 5 degrees.
I am glad there was some keyway left for the breaker cam to use as a guide to line up.

Now I am just jealous of Ricks set up.  I have always wanted a mill, but have not bought one because I can use the one at work.
Thank you,
Scooter

Thank you all.  It was way too much work for such a simple mistake.

I also inherited my first lathe from my grandfather.  It was an Atlas/Craftsman 6". I passed it along to my nephew about 12 years ago, and replaced it with a SB9A, which I still have.  I supplemented it with a SB13.  I also have a Millrite vertical mill. I love having these machines, it allows me to make many things.

I inherited this lathe and all tooling from my Grand dad.  He taught me to machine.
I have a small drill press and bandsaw and a 6" lathe I bought.
love to machine.

OK Scott, you have to post a picture of your lathe.

I turned the bearing around so the thrust would be in the correct direction and have about .015" end play now.
My inner bearing is Koyo 6205 and no spacer.  I did see a note in the manual that eventually they did not need it. 
Thank you,
Scooter

If you used the wide bearing, you probably wouldn't need a spacer at all.  Good that you got it figured out!

I made a new headlight coil and ran it.  It only barely lights the 21 cp bulb.  It is 10 volt at 1.35 amps.
The amperage is low so I am wondering if my magnets are weak even though I have good ignition spark.  Probably not going to mess with it anymore unless I get the flywheel charged.

New coil is:18 gauge wire at 297 turns using approximately 88 feet and .56 ohms. I made it longer also. The core is 1.00" and finished out at 1.85 x 1.85 x 1.05 long.  This size is almost too big and close to rotating magnets.

Old coil is: 22 gauge wire at 310 turns using approximately 81.5 feet and 1.3 ohms and core is about 7/8" and finished out at 1.43 x 1.35.

When I installed it I was wishing I had shimmed the wide side where the bent tab goes about .015 more.  It was hard to push on.

Attached are pictures of the fixture to wind it and you can see the shims I had to add because the core is a little bigger than half inch and is wider in one direction.  The carboard core in the picture is from the original, I forgot to take pictures of mine.
Thank you,
Scooter
