hello
to be honest I dont really know, it was obviously done before I bought the Lathe, The Lathe has been sat in my garage for over 2 years, as I work overseas, and it's only with the Lockdown in the UK (COVID-19) that i have had the time to start sorting things out in my workshop.
I started to strip the lathe down to clean it and was operating the chuck when I noticed the crack.
Also one of the jaw guides was damaged, so i removed the chuck completely and took the jaws off and thats when you could see that it was no longer fit for use.
Cheers
Steve
