hand held scanners
I've been thinking of buying one of these to copy parts, ribs, bulkheads, etc. off the plans so I don't have to cut them up.. Anyone used one for this purpose?

I don't know about now. Back in the '90's I tried a handheld scanner, problem is, or was, if you don't drag it at a consistent speed, then it will stretch where you pull faster and squash were you drag slower. Also, if you didn't drag it in an exact straight line, an arc in other word, then the top of the arc would be stretched. For me it wasn't accurate enough to use. They may be better at correcting those deviation now, or they may not be enough to bother you. The software had tools to "deskew" the photo. I never could get one that I could print it full size and lay it on the plans and it be an exact match. Maybe for ribs and formers you might get usable stuff...I don't know, and maybe they are a whole lot better now. I've actually scanned several full size plans using my all in one printer/scanner, and stitched it all together, it worked pretty good, and would be useable, but I haven't ever printed it up full size and laid it out over my plans to see how and where it might deviate. Right now, I'm playing with using my digital camera to do the same thing. If you make sure it is parallel with the surface of the plan and centered it, it might be useable, but there is lens distortion to deal with. There are some tutorials on Youtube for this on artwork, how to light it, and set your camera up. And of course I just deleted the ones I did about an hour ago. They were looking pretty good, but too bright, when I took them I didn't know how to light it, and the plans I was doing are on glossy paper so it had a bright glare in the middle. But with the digital camera photo you can use a photo editing software to correct the lens distortion, again, I've just started playing with this and don't know how close it will match up to the actual plan when printed at full size. I've done plans where I had to stitch 12 pictures together with my scanner/printer, and the scanner was less than $40 after rebate when I bought it. A flatbed scanner will scan a rib up to 10" or more on some, in 1 pass, with little or no distortion.

So I got the scanner in the mail, tested it and it works pretty well,, I didn't get any distortion, but it does seam to be enlarging when I print it out. I'll have to figure out why that's happening
I also got about 200 legal and court documents,, the knucklehead on ebay never cleared the memory card,, but for $17 shipped, I'm happy so far.
