New to all this so be gentle
I got this Super Adept lathe recently but the problem is it didn't come with a big chuck, previous owner only had the sort of chuck that would usually be on a drill and while it does fit on the spindle it doesn't allow for a work piece diameter more than 10mm.
The lathe has a 3/8" spindle and I am struggling to find any back plates or chucks 1st or 2nd hand on the internet that have the right size.
How do I obtain a back plate that is the right size for the lathe? Will I have to get one made specially for the lathe?
