Done the same as knurling pretty much, and works well. Here is a link to explain that procedure a little more.

Fuels have a lot to do with, and also head, and guide material that you are working with.

I am familiar with the Winona bronze coil guide repair. Don't see too much of that anymore. Guide liners have supplanted that method of guide repair. I didn't mention it because it's more in line with guide replacement rather than knurling.

I agree. The type of fuel and head makes an impact on the type of guide repair or replacement consideration.
