I'm curious about something in the way that you've secured the glass to the frame.

In the first photo in this thread, you can see the rabbet along the frame edge that the glass fits into (this keeps the sharp glass edge from being exposed). However, in your latest photo, you've gone to using what appears to be 1/2" aluminum angle to secure the glass.

Is the rabbet still there, or did you trim that off. I'm wondering what those screws holding the aluminum angle are going into. There wouldn't be much material left if the screws were going into the rabbet wall.

No, the rabbet is still there. It's deeper than the glass, which allows a strip of self-adhesive door insulation foam tape to fit on it for cushioning. The angle is plastic, and bent nicely over the apex.

The screws went in nicely, but I'm going to change for a larger size because I'd like a better overlap to hold the glass in.

OKay, well I'm impressed.
Even with the lashed-together configuration I have right now, I scanned my second book this morning and it was a fast as flipping pages.
The OCR software pulled the images off the camera and they're as crisp as if I'd taken to the book with a scalpel and a flad-bed scanner.

Cute little screw and nut for securing the camera turned this afternoon.
The camera end thread seems to be imperial pitch so there were a few nervous minutes when I had to set the change-gears in my lathe for the first time to cut the thread. Came out okay.
The other end is just an M6 which was a lot more civilised.

So, away with rubber bands holding the camera in pace and hello stable images.
Will glue a strip of rubberised pad to keep the camera slipping though.

Nice! Lathes are awesome tools. I've been buzzing with impatience since the lathe at my makerspace got totalled by someone driving their car through the wall.

...since the lathe at my makerspace got totalled by someone driving their car through the wall.

Man, that's crazy! If anyone goe video of that maybe at least you can get some solice from a few hundred dollars selling it to TV. Not sure what the U.S equivelant of "You've been framed" is though.

Yep, many's the time I've said "Argh, I need a xxx. Oh, hang on, I'll just pop up to the workshop and MAKE one on my lathe"
Best of all, it was a present from my parents. Mum, Dad, I LOVE YOU!

Next up, the book cradle. Got all but the four angle pieces cut out now

Well, that's pretty much got the platern module finished.
I put on a much better bracket for the glass. The plastic angle was just too flimsy and I was in fear of the glass slipping out and cutting me to pieces.
The whole frame is glued together now and it's rock solid.
I used strips of self-adhesive draught strip at the edges of the glass to cushion and hold it firm against the nice new aluminium brackets.

I filled and sanded the small gaps where the crossmembers slot into the front and back plates to give a nice finish.

Finally, B&Q sell some great VERY Matt Black emulsion called "Rebel" (presumably aimed at the teenage market for painting their rooms black!).
All in all, very pleased with the results - and of course I now it already works




Next step: Source some rubberised mat to put on the camera mounts to stop slipping, add lighting.
I've got some lovely LED strips from IKEA that ought to work well.

Very pretty indeed! I'm inspired by the attention to detail. Look forward to seeing more.

Thanks Dr.

And so to the book cradle. I've tried something a little different here and have constructed a mechanism to crank the right hand leaf open and closed to accomodate varying spine widths.
I started with a threaded rod, turned down on both ends to form a shoulder. (Hugs Lathe.. )
In the middle of which, a captive nut that wil travel along the length of the threaded area while the rod rotates.


This is mouted both ends to hold the rod in place. I simply drilled holed in pieces of MDF. No need for bearings or anything fancy. A washer both ends of the shoulders protect against wear on the wood.
At the moment, it's all held in place with a goodly sized slap of PVA. I reckon that should be all I'd need to hold it. PVA sets harder than the wood, so the blocks would give in before anything moves.


And here it is all assembled awaiting a handle of sorts. Might just make a wheel to go on the end to save on clearance.


The left-hand leaf will be fixed in place.
