isotropic helicoid 3d models

By making the globe and the vanes of light paper, a body is obtained rigid enough and light enough to illustrate by its motions through air the motions of an isotropic helicoid through an incompressible liquid. But curious phenomena, not deducible...

I've designed a helicoid can carry vintage medium/large format lens. I've used a Topcor lens which were used on horseman field cameras, such as 970, 980 etc. the reason I didn't use the most commonly used Mamiya sekor, simply because they are...

This is a variant of the WillTravel large format cameras (4x5, 5x7, 4x10 or 8x10) with a M65 focus helicoid and not the rotating frontcap in the basic design. This design requires that you know the lens Flange Focal Distance (FFD) with a mm...
