Fabrication Steps
(note: part numbers refer to the recently-published parts list on the Bill of Materials page)

Step 1: Weld Press Plate and Spacer Assembly

 * 1) Lay the spacer tube on top of the press plate, align the sides and make the back edge flush. [[Image:Tubepress.jpg|thumb|200px|Steps 1b, 1c]]

 Tack weld the two together in many places (at least 3 on each side) to ensure nothing will warp. Double check everything for squareness!!  Weld the two together on all edges where they touch.

Grind off any weld which prevents the vertical support from being square and flush with both the spacer tube and the press plate. Weld the vertical support to the press plate and spacer tube assembly. Grind down the welds on the open end of the tube so they are flush with the rest of the tube.

Step 2: Tack Sides
 Tack the sides to the tube on all sides in multiple places except where it is touching the table. Add a few 1" seams to prohibit them from moving.
 * 1) Lay the spacer/press plate assembly down so the press plate is touching the table.
 * 2) Align side pieces with spacer and press plate assembly. Insure the two are square vertically and horizontally with the spacer, and that everything is touching the table.

 * See Shims video

Step 3: Tack back

 * 1) Place the back piece.
 * 2) Tack the back piece in a few spots, with a 1" seam on each side.

Step 4: Tack Roof, Inner Rails

 * 1) Grind off the welds for the back and side pieces so that the entire drawer is flush.
 * 2) Flip the drawer over and tack the sides from the top.
 * 3) Place the roof and inner rails in their respective places. The inner rail placement differs from the diagram shown. They should be sticking out 5" from the roof, therefore about 5" from the back. Ensure inner rails are perfectly parallel (varying no more than a 16th of an inch) and square throughout the entire length.
 * 4) Tack them in multiple places except where they are touching the table.

Step 5: Tack outer rails

 * Tack them in multiple places except where they are touching the table.

Step 6: Weld entire drawer



 * 1) All the seams should be completely welded except the difficult to reach places between the inner and outer rails, those can be welded about 50%.
 * 2) You may want to grind off the welds in between passes around the drawer to allow it to cool.

Step 7: Grind the entire drawer flush

 * Make sure there's no welding spatter where the rollers will be rolling. Grind any off with a small grinder.

Step 8: Check the Rails

 * The rails likely got warped outwards on the side with the back while you were welding.
 * If they are not still parallel, you will need to pinch them inwards so that they are. You can do so using two C-Clamps.
