I agree, grinding is the hardest for me. That was my first batch from scratch, that went out to HT. I didn't realize they needed to be "finished" before they went to HT. It took a lot of work to clean them up to that point, lol.
I was sending them out to HT with an 80 finish. I didn't realize that they come back black, and the scratches show more when they are filled with the black scale. Live and learn.
The last one I did was sanded to 400 before HT, so we will see how that one comes back. I am picking it up Friday.
Hopefully I will be ordering my Esteem grinder this week, that should help with the quality of grinding too. It's hard to find belts for the 1x30.
