2.  TOOLS AND EQUIPMENT

Building an FAL requires a certain minimal set of tools and equipment.  While some of these tools can be obviated or jury-rigged, in all circumstances, we opted to obtain the proper tool so as to err on the side of caution at the expense of economy.  The list and total expense are deceptive as many of these tools are already in the home workshop.  The table below indicates the tooling and gauges we used for the project, source, purchase price (excluding shipping) and any rationale for our use of that particular tool.  All prices are strictly retail - many of the vendors listed give substantial discounts to Type 03 FFL holders.

Bench Vise, Wilton Tradesman, 6" Jaw

$299.95
A good vise is absolutely essential when building an FAL; it is needed for mating a barrel to a receiver, removing the receive stub from a barrel, and holding the barrel steady while installing the muzzle device.  Additionally, it can be of great use when installing the locking shoulder.  Minimum jaw size should be 4.5" with bigger being better.  That being said, there are many vises available at 1/3 the price.  So why did we choose the Wilton Tradesman?  Simply put the Wilton was one of the few vises available that boasted a tensile strength of 60,000 psi.  Most other American made vises have a tensile strength of 30,000 psi, and Asian imports often less than that.  We interviewed a number of people who'd built FAL's, as well as several gunsmiths, and machinists.  Almost every one of them had broken one or more less strong or less expensive vises before moving to a 60,000 psi vise.  We opted to skip the breaking step.  We're not saying that you WILL break a vise while building a FAL, but why take the chance?
Digital Calipers, Mitutoyo "MyCal"
Enco
800.873.3626

$94.00
You'll use a caliper to determine the proper headspace dimension as well as measuring parts for dimensional differences.   Digital calipers are nice, as they very easy to use and many have a measurement resolution of +/- .0005", but you will not be ill served at all with a less expensive dial caliper with a measurement resolution of +/- .001".   Whatever calipers you choose use, make sure that the measurements are consistent and repeatable.
Pin Punch Set, Starrett No. 565
Brownells
641.623.4000
http://www.brownells.com
$33.50
You're going to need to punch hardened steel pins in and out of various pieces of the FAL.  While brass punches will work in some cases, there are many requirements for a hardened steel punch.  These punches will also find many uses in general home gunsmithing applications.
Roll Pin Punch Set
Brownells
641.623.4000
http://www.brownells.com
$22.85
Purely a nice to have.  Makes it easier to install and remove roll pins that you may use to replace missing or damaged solid pins. 
Roll Pin Holders

Masen Brass Hammer and Punch Set
Brownells
641.623.4000
http://www.brownells.com
$27.95
Brass punches are particularly useful when you want to avoid marring a surface or damaging a steel component.  As with the Pin Punches, the brass punches will come in handy over and over again.
16 ounce Claw Hammer
Sears
$17.95
Needed to start and/or drive the locking shoulder home, as well as to aid in moving or removing pins.
Hollow Ground Screwdriver Set
Brownells
641.623.4000
http://www.brownells.com
$45.60
You'll need screwdrivers for general assembly work.  The advantage to a hollow ground blade is that it fits the screw's slot perfectly, and transfers the torque equally to the entire slot, minimizing the chance of buggering the scre head or scratching the surrounding metal.
