DIY Different types of homemade sharpening stones 

Your projects are always a lot of fun. I thought the sandpaper micarta was a cool idea, even if it didn't work out.

Very interesting projects, I have a concrete / masonry diamond wheel that I bet would flatten that real quick! 😃

Still on the project mate, hope you figure it out and start a stone making business 😁

The bondo one seems interesting to try an make. I wonder if mixing a 10k aluminum oxide with bondo would act like those old razor hones in barber shops. Is the fiberglass resin abrasive on its own? Does it slurry? (make mud when lapped with I diamond plate)
