Just picked up me 7" square by 19mm plate glass from the glass place today. I have mounted the 6" cutter on the headstock of my wood-lathe and have secured the head-stock in a position above the glass-holder on my lathe bed.

I have some scrap pieces of glass to practice on so i can get the pressure on the glass right to cut\grind and hopefully not smash the glass.

I have welded a couple of light welds in four places around the edge of the pipe cutoff i am using for a cutter and ground these to teeth with my angle grinder.

Will these welds\cutting teeth be enough to cut\grind through the glass or do i need many more teeth to help the grinding process?

Will mild steel\welds be good enough to cut\grind the glass or do i have to braze tungsten cutters on the cutter instead?

The glass square only cost me $24 Aus so if this works, i will have very cheap glass circles compared to $115 Aus i was quoted for one circle from the same shop.

If it doesn't work, it just means i can strike this method off my list and try again. There must be a way that the home-handyman can cut\grind his own circles!
