After a few years of reading threads, it seems like there's some tools that the old timers recommend against (except for very specialized circumstances, like having parkinson's or motor control issues):
- dovetail guides
- jointer plane perpendicular fence.

I'm pretty sure there's others...

Do you guys still feel that way? Are there other tools that I should avoid, so that I can develop proper technique?

ps. FWIW, I'm making some Barron dovetail guides. The wood has sat in my workshop for about 6 years, and I figure that it'd make a nice present...if nothing else, really good dovetail markers.
