Re: Gear Cutting

It's all about the grain in the phenolic laminate.

I had to make a batch of hydraulic pistons from phenolic and it would have been simple to part them off of phenolic rod, but I had to cut plugs from sheet using a hole saw to make then from to get the required strength due to the grain.

Re: Making a Silicone Soldering Brush

Any idea of the age of the one shown?

Re: Balancing grinding wheels- my new page

I gave up on it and used a different wheel. I balanced and re-dressed, then balanced and re-dressed again (as re-dressing after balance can alter the balance) and it still left a choppy finish as if it was out of balance.
