i am seriously considering milling my head for higher compression diy style. There was a post with a guide that says to take glass or something really smooth like that and put sand paper down, lube up the sand paper with some oil, and then do figure 8's until you get the proper shave.
has anyone ever done this before? I'm pretty sure I'd be spending less than 50 bucks at the machine shop.
If anyone has done this DIY style, how did you keep the head level as to not grind down too much on one side. Also how do you measure thousandths of an inch? it was recommended between .020"-.030" with the goal of .025"
Maybe I could put washers around the head to keep it level and not go too far. any tips, know-how or ideas will be greatly appreciated.
