Porting an engine with a drill will destroy it.
Plain and simple. No ifs, ands or buts. I have a die grinder, but nothing more than a pancake compressor so actually using it is painful. I could buy a larger compressor, but then I have to find someplace to store it. Having everything else I need to start the porting process, I improvised. Chucked the parabolic bit into my drill and had at it.
4 hours, and only one oopsie, later, I had a nicely ported intake, and a drill with a chuck that wobbles like a drunken sailor. I'm talking at least 1/2" of play at the tip of the chuck. Fortunately, these drills are cheap at Northern Tool. I can get them for $15 when they're on sale. The extra handle gives you a lot to hold onto as you're grinding away; hence, the single oopsie. You hate for tools to be considered disposable, but in this case it worked out really well.

You've discovered the reason you can buy them for $15. :-) I buy a lot of stuff from Harbor Freight (a lot like NT), but I haven't had much luck with their power tools.
I've tried to get familiar with where all the 'well stocked' pawn shops are located in the areas where I typically drive. If I have time, I stop in & look over their tool selections periodically. Around here, I'll see the putrid green $25 B&D homeowner grade drills priced at $35 & right beside them, B&D 'HolGun' series (~$175 retail) for ...$35. Same story for industrial grade Skill & Milwaukee tools. The only way you'll wear out one of these industrial grade drills is to pour grinding compound into the bearings.
For one-time work like you're doing, HF sells an electric tool with a 1/4" collet for about $20 when it's on sale. It's intended to be a laminate trimmer, but you can remove the 'foot' & it will function like a high speed air grinder.

Now, how do I get my freshly installed Puppy Linux computer to automatically recognize shared folders on my Windoze computer attached to the same network?
