Gary, what is the indexible cutter you are using?
Also with your HSS lathe bits, are they chinese HSS or name brand HSS?
Whoops one more 
Would something like JB weld which is steel/cast iron coloured camouflage the sand blow holes in the flywheel?
Well Gary that was 15 minutes of thorough enjoyment, much better than TV!
Thanks for taking the time to explain each operation so clearly.
Thanks very much Jim for the kind comments.
Answer to question one, not sure the cutter came with the lathe when I bought it. (with lots of tips)
The HSS cutters I bought online from (ozmestore1) I suspect they are chinese but very good quality and his service is very good. (Australian seller)
And yes I too thought about JB weld, might give it a go.
