Is it just me or does every woodowrker find that when building a jig or
some other thing for the shop, you need the thing you're building to
build it?

Some examples:
* I needed a cross-cut sled to build my cross-cut sled.
* I needed a router table to buid my router table (see Norm's New
Yankee Workshop New Improved Router Table where he uses the old version
to build the new improved one.)
* I needed a bench with vises to build my bench with vises.
* Etc.
