Below are a few pics of the focussing rail I have been working on for the past month. It consists of a Zeiss Jena Laboval 4 microscope focus arm mounted on its back on a wooden base.

The condenser has been replaced with a wooden stage for mounting the camera/bellows. This allows the camera/bellows assembly to be moved horizontally via the microscope’s coarse and fine focus controls. I didn’t remove the bracket that would normally support the microscope stage. It isn’t in the way and I didn’t feel like sawing it off. Besides, it has holes drilled in it that might eventually be useful for attaching some structure of some sort.

A shaped wooden block was attached where the microscope head would normally be affixed. A microscope mechanical stage has been mounted sideways to the block to provide lateral and vertical positioning of the specimen. The specimen is held by an alligator clip which is mounted on a universal flash shoe, which is in turn mounted to a dovetail groove that runs along the (now upper) edge of the mechanical stage. If the brass nuts are loosened the entire assembly can be slid along the groove and repositioned.

I used the rail to take the fruit fly photos in this thread: http://www.photomacrography.net/forum/viewtopic.php?t=19039&highlight=

After taking those pictures (to test the functionality of the rail) I completely dismantled the assemblage, finished and painted the fabricated pieces, and then reassembled it. It’s amazing what you can build on your kitchen table with a cordless power drill, a selection of bits and a few hand tools!

When I photographed the fruit fly the flash was supported on a separate stand. So my next step is to add a more permanent mount for the flash (or flashes). I also want to make a removable platform that could fit on the mechanical stage in place of the universal flash shoe/alligator clip.

Then it’s a matter of taking more photos!

I have to say that designing and building this contraption has been way too much fun! Once it’s finished I think I’ll start working on a vertical version!

Cheers,
EC

Ernie,

Good job!

The problem solving aspect is an enjoyable and rewarding component of such an exercise.... Smile

A very neat and practical solution. Excellent.

You have motivated me, Ernie.

Now I know what I can do with all the Laboval4 stands I have.

I have a Sony a100 and have found some bellows sets on the web.

I'm not sure about the adapter for the microscope objective.

I guess I'll have to paint my set up green if I want to claim any originality.

Thanks,

Gary

LOL! You have spare Laboval4s? That’s handy! I need to buy another one to build a vertical version of the rail. The Cnscope lens I am using cost a whole $20, shipping included. I was lucky enough to but an original Olympus adapter for the Olympus bellows from another member of this forum. But you shouldn’t have trouble getting adapters on Ebay for whichever bellows you get. I have a couple on their way to me for mounting a enlarger lens to my bellows. The two that I need cost me less than $5 with free shipping. Truly amazing prices!

I also have a number of other lenses on their way to me, including a JML 21mm. So the quality of my photos should improve soon.

Cheers,
EC

Ecooper,
It's a nice setup!, it feels solid and versatile and I like in special the fact that most materials seem to be very inexpensive. A good idea to reverse the microscope stand working desing Very Happy
