Die grinder and bits for porting- it's been a while

I’d like to see what people are using nowadays. There used to be a guy in town here who used a big Milwaukee die grinder with abrasive rolls to match and clean up ports. When I was still working on motorcycles I ported dozens and dozens of two-stroke cylinders, and a few four-strokes. I used a CC Specialties rig that was basically a Foredom unit set up for porting. It had a foot pedal and a hanger hook that made it very easy to use. The tool holder was set up with a 1/4” collet that worked will with the various carbide tools that I used, both long and short shank. It was easy on your hand, too. I also had a 1/8” collet adapter for small burrs when I needed them. Beeswax was my favorite lubricant. It would load up my burrs sometimes but that was easily taken care of of with a brass brush. That setup helped pay my way through college and buy my first house. I still have it. The drive cable broke some years ago and CC Specialties was out of business when I tried to get a replacement. The motor never failed and I don’t think I ever replaced the brushes even though it came with a spare set. If anyone knows where I could get a drive cable I’d like to know. It looks just like a speedometer cable. I’d fix it up just for old time’s sake. I also used some pneumatic die grinders like Astro and Florida Pneumatic. They lasted pretty well if you pre-oiled them, but I did wear out the bearings in a few of them. Long shank bits seemed to make them more prone to chattering when worn.
