X-Head Porting....

Got some smaller bits... thanks @yellow rose. My favorite one is the oval egg shaped one... one slightly larger than the one I got might be the perfect one to accompany it...

I also bought some stones (which die fast) to smooth where I have a hard time doing with the burrs. Im going to cut the bigger Christmas tree down where it vent and then use that.

I also agree, variable speed is the way to do this...i used my air pneumatic grinder today, kept running out of air really fast, but it worked better.. Im going to get the harbor freight variable speed electric grinder...

Im having a hard time getting this hump..

Who knows in a few years of grinding on teeth you may be able to give up your day job.
