I designed it in Fusion 360, then 3d printed it in ABS. Each ring was printed separately to avoid using supports and to make it easier to clean up the inside surfaces. Acetone was used to glue the sections together. It was one of my earlier designs using Fusion 260, so it's not parametric. That woul...

When you said dental wax, I thought perhaps machinable wax would work, but the melting temperature is probably too high. Dental wax seems to be readily available at any drug store pretty economically, but I don't know if it's the same type of wax as Thomas Eisner used.

Not missing anything. I think it's fairly weak, so it might be removable. There are probably better adhesives that can released easier without harmful chemicals.

Would 3M type 77 adhesive make it easier to remove the fixture after the shoot?

I try to use the same start position for each stack as I think this helps keep the perspective the same. My rig is designed for spherical panoramas which helps keep the perspective the same from frame to frame. Orthographic stitching will always have parallax errors unless the lens is telecentric. M...

This hood has worked well for me. It's rectangular. Any light hitting the side is reflected back out.

Yes, but it helps to have it on a stage for initial focusing and composition.

100mm is a little short for focusing with the bellows. Perhaps having replaceable lens mounting brackets would work.

Do you have a link for this?

Is having the lens moveable and the camera moveable independently useful?
Definitely if you want to shoot non-orthoganal panoramas. Moving the lens' entrance pupil to the rotation point for the panorama is easier than moving the rotation point.

Put some other (already ripe) fruit which ripens with ethylene in a brown paper bag with the bananas.

Look at how the vertical extrusion is held to the horizontal. I expect I'll put a diagonal strut "behind" on each side, but I don't have a great way to measure the 90º. With a part like this , you don't need to measure 90 degrees. Once installed you can use the camera and Zerene Stacker to precisel...

Thanks guys. Unless I'm misinterpreting, ebay 352575728985 has T8 x 1mm , 200mm long with a nut, for $3.89. And 272767923336 is a T8mm x 1mm anti backlash, though I'm thinking that gravity would make it redundant? Not sure where an idler might best go. It's not much like the Wemacro stand. A and B ...

I used an Uno in my first automated stacking setup, but controlled it with either an Android smart phone or a PC over a Bluetooth connection. The PC interface was fairly simple to implement, but the Android was not.

I'd recommend a 32bit microprocessor like the Teensy 3.2 or 3.5. They are Arduino compatible, have many more pins, and are quite a bit faster than an Uno.

A touchscreen like a Nextion is a lot more versatile than an lcd and buttons.
