I've gotten reasonable effects with a tiny round burr, but reading James' comments i think different burr sizes might make a more natural effect. I might experiment with that next time.
This may be a daft question, but why would people do this? Is it simply a lack of a sandblaster?
In my case it was both the lack of a blaster and trying to match repaired sections to an existing blast.
But are there any other benefits? Reshaping flaws that would look bad blasted?
The only reason I can think that this makes some sense to do is lack of sandblasting equipment. It takes way longer to do this faux blast than it does to actually blast a pipe. There are instances where being able to mimic the pattern of a sandblast comes in handy. Lindner and I were just discussing this last week. Nate has an awesome pipe on his bench where he's mimicking plateaux on part of the pipe.
Lack of room for a blaster is one reason. Another, after doing it for a long time you get use to it, helps when doing some types of repair work. Gives me reasons to buy lots and lots of bits!

A definite yes, there. "Spot matching" blast texture BY blasting is effectively impossible and impractical for many reasons. Matching by hand is quick, safe, inexpensive, and---with practice and the right tools---impossible to detect. It's the pipe version of those Old School auto body men who could invisibly metal finish a fender or door.
UFOs must be real. There's no other explanation for cats.

I fall into this category. I don't plan on getting blasting equipment until I retire from the Coast Guard and stop moving every few years. I have enough power tools that are a pain to repeatedly move and re-set up as it is. This gives me about 8 more yrs without a sandblaster, which is why I've invested a significant amount of time and experimenting into finding a suitable rustication. I'm pretty happy with the one I'm using now.
