Thank you so much for your hard work on this really nice plastic tubing scanner!
I have just started building my own. It was a bit hard for me to get those plastic tubings here in Germany, this is not available in my local hardware store .
Just a quick note on the latest instructable version July 2014.
In step 1 there seem to be one 32cm pipe missing in the "overview picture (Step 1: Parts for the plastic tubing frame of the Easy Scanner)". You have written 1 x 32cm pipe but if I look at picture "Step 3: The Counterbalance frame" I need two (the one in the middle is missing)
One quick question: could you please tell me the diameter of the steel pivot rod ?
Best,
Elwi

Let me know if you spot any other errors please. I feel bad about the errors you found, but really glad you pointed them out!
The problem with "unusual" angles is how to hold the acrylic accurately at that angle. With 90 degrees it is easy of course, as there are lots of 90 degree fixings. I'll be interested to see how your plan works out.jkn wrote: FWIW I am thinking of having a larger platen angle than you (100 degrees instead of 90) so that will make a difference as well.
I used a 22mm flat drill, and it worked well. I think you'd be better buying a 22 mm bit if you haven't got one, because even doing it by drilling out took me quite a few minutes, and I reckon with sanding you would be really struggling.BTW, I am curious if there is any great art to drilling out the Tee-pieces for allow the tube to slide on? For 21.5mm 'overflow waste' tube I have a 20mm flat drill, but clearly using that will involve a bit of 'scraping' around the inside of the tee. I also windered about using a slightly smaller diamer tube and some sandpaper... would be interested in your experience of this.
I have found that mounting the light vertically over the gutter seems to be the best position. And I have had some problems with reflections, mainly (rather surprisingly) from off the black tubes, which are shiny even though they are dark in colour. I think this problem will best be handled by lightly sandpapering the tubes.FWIW I plan to use Canon a1400 cameras and a modified lighting arrangement, with four Cree emitters, maybe on a 'gantry' mounted on the top of the counterbalance support (where you have the sliding tee-piece currently. I am wondering if this setup, with a couple of metal 'arms' coming forwards, might result in a bit of light 'bounce; we shall see.
Please let me know how you get on. If you have questions as you go along just ask, but I will be away for 3 weeks starting next week, and I don't know if I will have broadband where I'm going. So you might have to wait for answers . . . . And you might be finished by the time I get back!
