Tapered Rectangular Bellows

**caesar2164** · 7-Aug-2009, 10:07

Hello all,

I'm new to this forum (just joined today) and am in the process of designing/building a custom 617 camera...

Here's a early render of the 3d model I'm making (it helps me visualize the size/shape/colors).

The brown will be mahogany, the yellow will be brass, and the bellows will be black or dark brown. The lenses I will use will be 90-150mm with a Schneider Super-Angulon 90mm f/8 and a Fujinon SW 150mm f/5.6 as the main lenses. The front standard will slide forward on two brass rods, pushed forward by a threaded rod.

Anyway, I don't know how to make the bellows, i was wondering how I would make a tapering square to rectangular bellows...

The standards are 2cm in width and the inside dimensions of the standards are 8.5 x 8.5 cm for the front, and 8.5 x 17.5 cm for the rear.

Any help in this regard would be awesome!

Looks good-

The best guide to bellows construction that I've found was from JB and Susan Harlin-
it can be found here- http://www.jbhphoto.com/articles/article.htm

I used it to make my bellows, and there are some pictures posted here, which might help-
a search for 'Arca Irish' should find it-
