You know, I had always stood while grinding. Yesterday I was cleanign shop and found a barstool I had laying around. I put it just behind my grindings bucket and sat down. There is something VERY natural about sitting for me. Its a bit scary, but I tend to grind by the "shadow", meaning I get my flats totally flat by judging my bevel contact with the belt based on the hairline shadow between the edge and belt. Sitting, I can really get a good lightsource up above me and I feel like I have much more control......I am going to be doing alot of my bevel grinding sitting down from now on. My grinds last night came out as good as any i've done, and it was my first time sitting.
