two belt grinders face to face?

[Drew Riley]

If you're looking at building one of these from a production speed standpoint, I'd encourage you to watch this video from 5:24 to about 7:00 and tell me which is faster.

If it's just from a point of trying to get even grinds more easily, you'd probably have better luck on one machine.

That is my grinder in the double wheel grinding video. It is a great roughing tool but it is not very good for precise operations. I use one of my single wheel grinders 90% of the time. It is hard to control the hollows on the double wheel grinder. The hollow in my blades is usually not the same as the radius of the wheel. I like to have a thin flat-ish section behind the edge and the blend that up the spine. I have a lot more control over the shape of the hollow on my single wheel grinders.

I have put a blade in from the top before, it pops through and lands on the cookie sheet I have below the wheels. It is not as scary as catching a blade on a buffing wheel. If I were to let other people use the grinder I would have the appropriate guards in place.

A bit off topic, but just wanted to tell you that you make some amazing straights. :thumbup:
