Assembling the Scanner Kit

This page will eventually tell you everything you need to know to assemble the scanner kit Daniel Reetz announced in October 2011, but for right now there are a lot of stubs and many of the directions in here are speculative. PLEASE CONTRIBUTE YOUR INPUTS BUT FOR NOW, THESE DIRECTIONS ARE TOO SPECULATIVE TO HELP YOU ACTUALLY ASSEMBLE THE KIT.

Bill of Materials

The parts for the scanner fall into 3 categories: wooden pieces that are delivered with the kit, mechanical parts (fasteners, metal handles, etc.) and electronic parts (lights, camera, action!).

Wooden Parts

The scanner consists of ? wooden parts. They are identified as they are first referenced in the instructions.

Mechanical Parts

A number of fasteners and such are needed to complete assembly of the scanner. <span style="color:green">I don't know if these will be part of the final kit, so I'm listing them all here (as opposed to the things like the camera and lights which are obviously not part of the kit.</span>


Electronic Gear

Also needed and not supplied.

  • A light that fits the hole cut in the Lighting Module.
  • 2 cameras
  • 2 screws threaded to match you camera's tripod mount but long enough to pass through the slot on the camera mounts. Exercise caution. If you use a screw that is too long you can cause damage to your camera! The wood is 0.72 inches (18mm) thick.

Assembly FAQ

What do you mean by "pocketed"?

When some of the wooden parts are cut, they are not the full thickness of the original piece of plywood. The area that's cut away is called a pocket. Sometimes we will refer to the pocketed side of the piece, meaning the side with a pocket cut into it. In some cases, the pocket is nothing more than a simple groove.

What tools will I need to complete the assembly?

Electric drill and bits, screwdrivers, pliers, (fill in, please)

Should I glue the wood joints?

Notched parts should generally be glued if they are not held in place with screws. If screws are used, do not also use glue. In particular a couple of parts are designed so they can be reversed depending on whether you want left- or right-handed operation for your scanner. Gluing them in place would prevent you from doing this.

What are the main parts of the scanner?

The scanner has four major components: the Platen Frame, Transport Module, Lighting Module and Cradle.

Assembly Hints

Some mechanical assembly hints for the and kit.

  • Have a look at the assembly videos by Dan Reetz on youtube. Also, .
  • Hammer the wooden parts together with a heavy rubber hammer.
  • Hammer in the bearings quickly and evenly. Just hammer the bearing in a tiny bit, then turn the wooden part over. The bearings are now on the bottom side of the part, facing your work surface. Hit the wooden part with your hammer. The bearings will be pushed in much more easily and evenly.
  • If for whatever reason you need to drill a big hole entirely through the wooden parts, first clamp a piece of scrap wood to the bottom side. If you don't do that, you'll have wood splintering off the bottom side.
  • Use a few washers on the two 2.5cm 1/4" UNC screws to bolt the cameras to the frame.
  • When assembling the kit for use with Canon PowerShot A2200 or A3300 cameras, drill a 16mm diameter hole on the right edge of the linear camera UNC screw hole. Align the left side of the new hole with the right edge of the straight line hole. Align the bottom side with the bottom line of the camera UNC screw hole. TODO: picture.
  • Washers. The washers in the kit are not flat (on purpose). Assembling with the raised side towards the bearings. You might want to use two washers in most places instead of one as described in the original assembly manual.
  • Add felt pads to the end points of the lever mechanism. specific

Mounting the glass

  • Look at the inside of an aluminium bracket. You see six holes on one side.
  • Add felt pads on the other inside of the aluminium bracket, facing the holes. Leave 2mm space from the inside angle of the aluminium bracket. That leaves some place for the wooden rabbet edge.
  • Do the same for the other aluminium bracket.
  • Turn the imaging module so that the tip face upwards.
  • Cover the tips of parts 1 and 6 with the aluminium brackets without putting the glass in.
  • Draw dots on parts 1 and 6 through the holes in the aluminium brackets, 12 in total.
  • Drill the 12 dots: 3 mm wide screw holes approximately 12 mm deep.
  • Put the two glass panes onto the imaging module.
  • Put the aluminium brackets back in place.
  • Screw the aluminium brackets to parts 1 and 6 using the 16mm screws.

Handle assembly

  • Put two bearings into part 9 if not present yet.
  • Put a 70mm M8 bolt through the bearings hole in part 9.
  • Screw two nuts onto the bolt.
  • Screw the plastic handle onto the bolt.

Step-By-Step Assembly

Painting the Wood Parts

Materials Needed

  • 1 can black spray paint
  • All wood parts


  1. Paint all wooden parts with '''flat''' black spray paint. This is functional as it reduces glare.
