Is this anything like how you do it.

Here is what mine look like. Material removal is slow, but check your progress often. Feel free to PM or call me. TIR always less than 0.001" on dies I've honed.

Pretty good video. Once upon a time, I worked in an automotive machine shop. Reminds me much of a Sunnen hone for reconditioning rods and align honing main journals. The cylinder boring machine was even a hone type machine. Really course stones for rough boring and progressively finer until the classic crosshatch honed cylinder finish. Those machines have a gauge that tells you the resistance at tight and loose spots. Basically worked the tight ends to a neutral needle position, checking often at top and bottom with bore gauges... iirc. It's been a day or two. I was always a little bit of a gearhead so that job was fun but didn't pay much. Good people and a good time in life though. That part is priceless.
