A friend gave me a small piece of mulga that he had been hanging on to for about 20 years. I decided to turn it into this little shot glass that you will see in the attached (not very good ) photo. It is about 100mm tall and about 50mm at its widest point.
I was very pleased with the finished product. All of my 13 weeks of woodturning experience went into it.
However...
12 hours after taking it off the lathe it had cracked in about 5 places from the rim to the base of the hollowed section. These cracks certainly did not occur during turning or finishing.
Can anyone suggest a reason why this happened?
I am thinking that maybe I overheated the thing when boring the hole (35mm forstner bit). It did get quite hot.
Any ideas?
