Re: Daniel's Work Thread: Toward a Hackerspace Scanner

http://diybookscanner.org/forum/download/file.php?id=3730 Also, in this picture you can see my new air filter/chip separator combo, which is really working nicely. So far, very happy with it. Also visible in the background is the famous triptych by artist Manny Lus Cruz, "A Failure of Inspiration"....

Re: Daniel's Work Thread: Toward a Hackerspace Scanner

I'm a bit slow today. I still don't see what keeps that arm from moving toward the piece with the stud coming out of it and rubbing wood-on-wood. Could you draw a cross-sectional sketch and post it here? I'm lost on where those flat washers go. Oh, nothing! I'm just saying the bearing won't come ou...

It won't actually slide off the bearing, because you've cleverly arranged nuts and washers to prevent this :)

Re: Daniel's Work Thread: Toward a Hackerspace Scanner

Personally I can't trust a press-fit that's wood on metal. I'd much rather flip the arm around and have the bearing on the outside. That way, no large force in any direction on the arm has the potential of working the bearing out. But that's just me. On the other hand, if you glue the bearing in, pe...

I'm not sure Solidworks is very good for 2D. I've never had a problem with Illustrator importing into VCarve. But I know how much you like Illustrator ;)

Re: Shankha's 0.9.9 build

Shankha, your build looks great ! One thing that will help is if you make sure the machine is level, so that the cradle doesn't try to roll downhill. But other than that, the brake idea is a very good one. For the camera and trigger, you shouldn't need to readjust them for different books. Just adju...

Re: Daniel's Work Thread: Toward a Hackerspace Scanner

Wow, check out this interesting panel mover idea. Cheap, and I can easily make it on the CNC. I really like the idea... only downside is that it is currently more convenient for me to load sheets the "long way". I'd think it would be inconvenient to have to push your 4x8 so that it takes up the mos...

Re: Oxford eBooks scanner

It is definitely looking like something! Did you put a small spacer such as a washer between the two bottom supports? If you don't, the arms you have in the foreground will tend to rub against the rear supports.

Re: Daniel's Work Thread: Toward a Hackerspace Scanner

Instead of milling reverse grooves on the clamp board, you could drill holes in a plywood panel and then glue in 1/4" dowels located away from where the tabs are. Like in the original clamp board idea, you have slots where the router bit goes in to cut the tabs. Make the slots wide enough for the c...
