If anyone is considering building an engine/gearbox properly then he is
a list of more specialised tools that should be at least available when
working on your engine.
Micrometers 0 - 1" , 1-2", 2-3"
Vernier calipers 0 - 150 mm
Depth micrometer 0 - 1"
Dial Gauge and stand 0 - 0.5" or 1"
Feeler blades 0.001 - 0.035"
If you can afford it a dial bore guage 0.5 - 1" and 2-3"
Small hole guages (not overly needed but nice if you have them)
Cam timing protractor
Taps for thread cleaning, 1/4" UNF/UNC, 5/16" UNF/UNC,
Torque Wrenches 5-20 lbft, 20 - 100 lbft, 50 - 250 lbft.
A centre lathe (or a friend who can do machining for you)
A vertical milling machine (or a friend who can do the machining for
Slip guages (definatly a luxury item, perfect for rocker geometry
Plastiguage 0.001 - 0.003"
24in breaker bar at least 1/2" drive!

Some means of brazing.

Valve grinder (machine shop)
Valve seat cutters/grinders (machine shop)
A dremel or at least a drill.
Straight edge 24 in (this is a luxury)
Helicoil inserts (Decent machine shop will have these)
A selection of needle files
Hand file medium cut 12 in
Bastard file 18in .
Gasket scraper (decent one)
Some means of checking camshafts (this could be your engine that you are
building, or better still that old 998 engine you had in the corner of
the garage stinking up the place!!)
Some of these tools need practice to be able to use accurately/safely so
a friendly engineer is the best contact here. Others may need the
services of you local machine shop, but remember it is up to you to
check any machined dimensions to be sure that they are correct before
you build the engine. This is not a complete list but I will add to this
as I get time.
