There shouldn't be any 1/4" bolts.
The 5/16" bolts are interchangeable with 8mm bolts. I chose them and the skateboard bearings (a worldwide standard) for that reason. However the wood screws and pulleys may require additional sourcing.
I would love it if someone could put together a euro shopping list.
Hi there!
We, my wife and I, are about to go on a "little" shopping tour, dragging all of the printed shopping list AND the construction instructions to some kind of german Home Depot tomorow morning. Most likely we will drive some poor salesman nuts

in trying to hunt down all the bits and pices...
Just a "short" note on the measures you use, which are unfortunately all non-
metric 
: You CAN use these really strangely dimensioned bolts, nuts etc. in Europe but one would have to get a few non-
metric tool and YES, the are available in nearly any reasonably sorted store (but who wants to have two sets of tools unless one really uses them on a regular basis?). If you indeed have taken care of this little problem by choosing the 5/16" bolts and these ARE interchangeable with 8 mm bolts this would result in easily to handle standard (european sized) hardware

. Unfortunately, as the ESA and NASA had to learn the hard way, the transformation of inch into cm and vice a versa does not always turn out perfectly...
Anyway, I will keep you posted on a. the prices of the material, b. difficulties/problems in assembling the scanning thing/monster/tower, whatever, c. how it worked out to transform inches into cm (e.g., us simple europeans generally do not know what a 2 x 4 is...unless one has been watching the WWF many many years ago...in the time of Hulk Hogan and the Heart Brothers, when some kind of hilbilly carrying an 2 x 4 was part of the show

) and d. hopefully be able to tell you sooner than later how the project worked out. Oh, if someone would be interested I can poste the dimensions, in cm, to the interested public, i.e. in case things work out!
Ups, one more thing. On one of the pictures of the cradle the MDF plates forming the actual cradle show a miter. Which angle have you used? 45°?
And another thing: My experience with MDF is rather ambigous. One should NOT try to redrill a hole to close to another one as the material does not stand this kind of stress. I will look into options for MDF plates and keep you posted should you be interested.
Keep your fingers crossed and let´s hope I am not going to loose any!
