Now after looking at yours again I think I need to do more deburring and rounding...
Yeah the checkering isn't for everyone, there was definitely some times I thought maybe I was going to ruin the frame or screw up bad enough someone would notice. I don't think I'd hesitate to do another one, but I probably would do 25lpi (you don't have to go so deep) and I'd know a little better where to stop/start so that there wasn't nearly as much cleanup.
