The bakelite block in my 40-190 was the very first thing I did in the re-build. Heck, haven't gotten much farther than that because nice weather's been taking me outside. Bakelite blocks are not complicated critters, but they do require patience.

And a nice handy guide like the two listed above, plus:

Which is essentially the same info but with larger pictures. ;)
