Yep, I have had just one block of wood come away so far, I stop more often now and check for splits. I also dont stand in front of the lathe now when it starts up.
I am more worried about the dust getting into my lungs tbh, so have been using a good quality face mask to filter the wood dust.
The biggest headache is finding lead shot in good wood, as it stains the wood badly, it also seems to be quite common with the wood I collect from the coppice I work at!
I have been using this formular, once I have balanced and done the rough work:
diam in inches x RPM = must be between 6,000 – 9,000
Not sure if this formular works on larger blocks as the largest thing I have turned is 10 inches so far.
Looks like Ash might be cheap to get soon too 😉
