-##A Note on Tapping
+##Notes
 
-There is one fabrication-like step which may be necessary, tapping the MakerSlide. If your MakerSlide is not already tapped, and you do not have experience tapping it, it is suggested that you begin as soon as practicable. Do not however, attempt to tap all of the threads in a single session, instead, tap one or two threads, then proceed to the next step in the process. After completing on eor two steps, return to tapping. Doing it in this fashion will avoid the tedium of a lengthy session.
+###Tools
 
-Start w/ the short length which is used for the Z-axis Carriage (it only needs to be tapped at one end, so a failure to tap two good threads at one end will not render it unusable. Tap one thread at either end, then tap one thread in each of the remaining pieces of MakerSlide, then return to the first piece and start over, tapping a single thread in each piece each time.
+Only basic tools are required, unless one's MakerSlide needs to be tapped, in which case, in addition to wrenches, wire cutters and an assortment of Allen keys one will need an M5 x 0.8mm thread tap and handle. The 5mm and 8mm wrenches are close enough in size to 5/16" and 1/2" wrenches that one can substitute those, or when one needs 2 8mm wrenches, use a 1/2" and an 8mm. Similarly, the set screws should take a 1.5mm Allen key, but a 1/16" is only slightly larger and may afford better contact and be less likely to round out the screw.
+
+###Screw Sizes
+
+For the most part, it's obvious which size screw is used for what, but the M5 10mm and 12mm BHCS (button head cap screws) are easily confused — while it's not noticeable when the shorter 10mm length is used where one ought to use a 12mm, the 10mm screws are intended for use with MakerSlide insertion nuts and a 12mm screw is too long and will bottom out before beginning to hold anything in place.
+
+###Electronics and Mechanicals
+
+Please note that while the assembly instructions have these two separated, it is probably best to partially disassemble the electronics after testing them and mount the motors onto the appropriate motor mount carriage plates as you are assembling the machine for the Z- and X-axes. Putting this off will require either partial disassembly (Z-axis) or an almost impossible reach into a very cramped space to attach very small screws and washers (Y-axis).

By the time you're done, you'll be a pro (well, good at it anyway) and you won't have one piece which has all bad threads. Don't despair if you strip the threads on a piece — the default bolts for attaching MakerSlide are quite short and this is easily remedied by tapping the stripped holes deeper and using a longer bolt.

 Before we get all crazy bolting our new machine together, let's give our electronics a test run. It's frustrating to have the machine fully assembled, only to find there is a problem with your electronics that may require disassembly! Let's cut that off at the pass and give everything a thorough checking first.

-## Requirements
+**Note:** Do not attach one end plate during this step (despite the photograph showing this). Slide the Z-Axis Assembly gantry carriage (PS20031) from the previous step onto the gantry (see below) before attaching the second motor mount plate.

-Sub Gantry (PS20023)
+Push the MakerSlide as far as is possible to one end of the slot which the 12mm M5 bolts fit through. Only tighten the pair of bolts on the MakerSlide which is snugged up against the end of the slot, the other should be slightly loose. Note that there is a space in-between the two pieces of MakerSlide. This spacing will be set in a following step.

+Turn the eccentric nuts on the V-wheels on the Gantry Carriage (PS20031) so that they are as far from the static V-wheels as is possible. Carefully roll the Gantry Carriage onto the two pieces of MakerSlide, facing the spindle carriage away from the MakerSlide which is bolted in place at the extreme edge of the slot. Move the Gantry Carriage as close to the attached Motor Mount Carriage Plate as is possible, tighten the bolts for the loose MakerSlide. Attach the other Motor Mount Carriage in the same fashion, pushing down on the MakerSlide to ensure that everything is square. Ensure that the Gantry moves smoothly for the entire length of the X-axis. If necessary, loosen the M5 bolts and adjust the fit until everything is square and the gantry travels smoothly.

+
+### Squaring the Table
+
+Square up the wasteboard assembly carefully, since it will be the foundation for the balance of the machine.
+
+####Parts
+
+* 2 Y-Axis Rail Assembly (PS20026)
+* Complete Gantry (PS20025)
+* Waste Board Assembly (PS20024)
+
+Turn the eccentric nuts on the V-wheels on the Complete Gantry (PS20025) so that they are as far from the static V-wheels as is possible. Drive the Complete Gantry onto the two Y-Axis Rail Assemblies (PS20026), then attach the open end plates.
+
+Place the 10mm M5 bolts w/ washers into the bottom holes on the open end plates, thread on the insertion nuts, then carefully slide the rail assemblies onto the wasteboard extrusion. Check the alignment with a known-to-be-good square. One can also measure the diagonals to test for squareness. Ensure that everything is aligned squarely and that the Complete Gantry and the X-Axis Sub Gantry move smoothly. Tighten the bolts.
+
+Congratulations! You've built a ShapeOko!
+
+![](tPictures/so_complete_4.jpg)
+
+At this point, you will need to adjust the machine's V-wheels. These should be tight enough to hold things in alignment, but loose enough that the machine moves freely and smoothly. The suggested technique for this is, "Loosen the eccentric spacer until the V-wheel does not rotate when the carriage is moving and then tighten just (and no more!) until the v-wheel rotates when moving the carriage. Overtightening will lead to the V-wheel wearing out."
 
-## Squaring the Table
+You will also need to complete the wiring as documented in the next step.
