Re: Archivist Quill Kit Plans vs. Archivist Book Scanner Plans?

cday, Yes, that's the gap that I filled in a platen comprised of two glass panes. I wouldn't do that with acrylic though. You need to set the saw cut to 40 degrees, not 50. It's the opposite of what you think it is. The smaller the angle, the more "open" the platen V will be when the two cut pieces ...

Re: Archivist Quill Kit Plans vs. Archivist Book Scanner Plans?

Or did you just possibly use it to fill the larger gap in the right image? Right side. So miter with a circular saw with a fine-toothed blade? I haven't cut acrylic with a circular saw, but if I did, I'd look for a blade made for cutting laminate/plastic which is going to have a lot of teeth and a ...

Re: Archivist Quill Kit Plans vs. Archivist Book Scanner Plans?

Can we take it that you have at some point built a scanner with a 100º platen, and if so did you use acrylic or glass? Yes, I've built scanners with 100 deg. V-shaped platens. I used glass for these. The 0.125" thick glass panes were glued into rabbet joints cut into a birch plywood frame using sil...

Re: Archivist Quill Kit Plans vs. Archivist Book Scanner Plans?

If being able to break down the platen into two planes for storage isn't a concern, it might be easier just to glue a crosspiece of acrylic strip across the ends (forming a triangle - inverted 'A'). As Landin mentioned, that acrylic cement will melt the mating pieces of acrylic and make a strong joi...

Re: Archivist Quill Kit Plans vs. Archivist Book Scanner Plans?

Or maybe dpc could cut some mounting blocks from plywood or other board for you? Sure. I have a table saw and a variety of other tools and lots of scrap material. I don't want to get into the habit of making scanner parts for people, but a one-time thing is fine. Send me a drawing of what you need ...

Re: Archivist Quill Kit Plans vs. Archivist Book Scanner Plans?

You can get T brackets at Home Depot. On HomeDepot.com you can view the current inventory at your local store. Everbilt 3 in x 3 in Zinc Plated T Plate . You might find that 1/8" acrylic sheet flexes a bit too much when used as a larger sized platen pane. Here's a link to 1/8" sheet at Home Depot: 1...

Re: Archivist Quill Kit Plans vs. Archivist Book Scanner Plans?

You could also build that cradle lifting arm assembly from another, more rigid, material instead of small diameter plastic pipe. For example the Home Depot has 1"x2" (0.75" x 1.5" actual) hardwood poplar boards at $1.48 per linear foot. It's easy to work with and would easily take the sort of load y...

Re: Archivist Quill Kit Plans vs. Archivist Book Scanner Plans?

In the end, it's far more important that the platen panes be 100 deg apart compared to the angle of the cradle. You can make a 90 deg cradle and then put a stick or dowel under the spine of the book to raise it slightly to better match the 100 deg angle of the platen. I think what you want is ACRYLI...

Re: Archivist Quill Kit Plans vs. Archivist Book Scanner Plans?

I just read Landin's Instructable to look at his cradle design. All you need to do to support a different angle than 90 deg. is to bend the 90 deg 'L' brackets to whatever angle you decide to use (i.e. 100 deg). You're going to do this for the brackets you use to hold the platen panes together so it...
