You guys are making me feel ancient. I bought a Graves Mark IV back in 1980, and I’m still using it. It’s modified into a nice bench top with a washing machine motor. For years now, I’ve been wanting to get the 1/10° angle mod, but as it means sending my head back to Graves for probably a couple weeks, I manage to keep putting it off. The cheater is pretty straightforward, and I can eyeball the angles close enough. Learn to “cut a little, and look a lot”, and you can head problems off before they become headaches. I’m deaf now, so I don’t bother listening, but learn to get the feel of the quill when cutting. Learn to use your height adjustment to make your meets, and you don’t need a dial indicator. Use your eyes, and learn your adjustments!
Most problems with tables are caused by under or over cutting the girdle or star facets, use your eyes to make these as perfect as possible before you get to the table.
