One way to make a prop hub
I thought this might be of some interest to the group. This is one way, no the only way, certainly not the fastest way. I have had less trouble with my props being out of balance wih this method. It really bother me when the engine shakes more than it should so, I prefer to spend the extra time.
The wife is setting up a website. She wanted me to document some of the things I do while hold up in the shop. This was a contribution to the cause. If anyone finds any mistakes let me know so she can fix it.

RE: One way to make a prop hub
A flat bed scanner is a good way to do little flat objects. Here are the boring bar pictures. The black marks are for depth of cut. Basically a boring bar is a lathe tool sideways on the end of a stick. If you can make a lathe tool bit you can do this. Old two flute milling cutters make excellent boring bars. Drill bits work too.

RE: One way to make a prop hub
I notice your machine has a chuck "made in England" so not "all american" I guess.
Do agree there are many chinese rubbish machines out there, some are better than others, mostly the ones from Taiwan.
Not possible to get a "true running part" from a 3 jaw chuck after it has been removed and refitted after machining outer surface. Any machinist will tell you that, it is one reason why there are 4 jaw chucks. 1 thou runout doubles when you bore the centre hole.
Most 3 jaw from England will have around 1 thou so it is not surprising unless the jaws have been stretched or the chuck mis-handled at some time in it's life.
You can get a cheap 4 jaw made in India for example that will give 100% accuracy for these type of jobs even though they may appear a bit junky. Suffice to say the tailstock centre is properly aligned to begin with.
