In-Depth Information
Whatever tool you choose for measuring and marking, pick one that gives you the best chance at
marking cuts and drill points as accurately as possible.
Clamps
Ask most woodworkers and they'll tell you the same thing: you can never have too many clamps. And
since clamps come in every shape, size, name, and price, the best recommendation we can make to you
is to purchase them when you need them based on the job at hand.
For the 3D printer project, there are matched parts that are mirror images of one another. In these
instances, it's often easier to clamp the two pieces together and drill them at the same time, ensuring
that the drill holes will line up when the machine is assembled. (Many of these pieces also contain
counterbores, however, so make sure when you choose to drill two pieces at a time that you drill the
counterbores separately and on the proper sides specified in the plans.)
Squares
If you intend to check the straightness of the cuts on the plywood pieces, you'll definitely find a small
engineer's square useful. (A larger carpenter's square will work, but since most of the parts for the 3D
printer are less than 12” in length, a smaller square should be enough.)
Use a square to make certain all your parts have right angles. This will become important later in the
project when you begin assembling all the plywood parts and want to ensure that the machine will
operate properly and that no moving parts will rub or interfere with other components.
Screwdrivers and Wrenches
Screwdrivers and wrenches (and sockets) will be required during assembly. You'll need Slot and Philips
head screwdrivers; having electric or battery operated versions of these tools will save time and require
less energy on your part.
Drill Bits and Counterbore Holes
We talked about drills earlier in the chapter; now we want to explain that there are two types of hole that
you will be drilling on this project. The first type of hole is a straight-through hole. You'll select the
proper bit for the drill and drill a hole completely through the plywood. Straight-through holes are easy;
they are the sort you've been drilling since you first learned to drill.
Note For best results when drilling completely through a piece of plywood, we recommend placing a bit of
waste wood underneath the piece you are drilling into. This waste piece will prevent splintering of the wood
(forcing you to recut the piece) when the drill bit breaks through the piece you are drilling.
