I have been investing a lot of time now in the david scanner and I enjoyed it a lot
. And I learned a lot
The biggest lesson I learned recently is the importance of the corner. So I build a rock solid corner using wood and metal sheets to be able to use magnetic paper.
Man this was a big step forward in my results and ease of use.
But now about 3 weeks later the wood seems to have bent
(only a couple of milimeters) and this has a serious impact on scan results. I tried to straigthen it but I failed to straigthen it "good enough"
So I will make my n'th corner. But this time I want it to be the last (of lets say table size) so I've been reading through the forum searching for corner creation advise and I find very little information. I know the user manual has good instructions, but not complete enough for me. For instance the plastic sheets mentioned have no thickness. I'd guess 2 mm will not be thick enough but is 4mm thick enough? How long will this type of corner last? Can I glue a metal sheet on the plastic? Will it bend over time?
Has anyone uses metal sheets instead of the metal paint? (I don't seem to find the metal paint)
Moreover I would not know where to find these plastic sheets mentioned. I know quite some shops around but the closest I can think of is a plastic cutting plate.
My requirements to the corner are as follows
Ability to make the corner straight (be it by easy disassembly or turning)
Easy to make (the corner I mean; but easy is relative
Easy to put in 90° (prefably some locking system so it doesn't change when removing the magnetic paper)
Supports magnetic paper
The planes are perfectly straight. (We all have some experiances on this
Not to heavy
I do not have requirements as to
Cheap (I've spent to much allready ....)
Having a open corner and stuff like that (I'm all set up to do planeless scanning)
Anything bigger then 2 times A4 (For me this is a subject for later)
Any construction plans/tips/advise is welcome
