The bearing pads would be the Laborlux frame tabs in its female connector.

I just sold off my PLA printer. But someone in these forums was offering to print microscope parts. I can send you some files if you want. Maybe that other poster would print something to test with.
That would be awesome, I can probably find a local 3D printing business to print the files....I also purchased a Diastar that came with a CAS200 metal box that could " "probably " be modified or at least partially used , that being lens, etc

Frankenstar 420

I wonder how lab tables had to be reinforced back in the 80's due to the wight of this set up?!!

Have lab microscopes become that much lighter in weight since the 80s? I think the tables have always tended toward the massive, not just to bear the weight but also to dampen vibration.

Actually, weight is an advantage when it comes to high resolution microscopy. The first binocular research microscopes were in the 20 + lb. range and increased from there . I think a Spencer 5 , which was a stsndard format horseshoe base 4 objective research scope weighed in around 25 lbs. Any decent scope attempting to provide a stable image to a coupled photo system needs some weight to overcome possible vibration issues. The Diastar is neither too heavy nor too light.
I find it a perfect stand for many microscopy systems. Even the 100 watt lamp house is decently compact and cool enough to do just about anything you want.
The Spencer 5 , mounted on a 100 watt Ortho-Illuminator is physically slightly larger , so I would say microscopes have not necessarily gotten larger but some like various all encompassing beasts like a Photomi or a Univar or various other universal type stands are truly over the top but their results to some degree justify that.
The nice thing about a Diaster is that now, 35 years after it's first introduction, diligent shopping can put one in your hands for less than 500.00 and it can still be close to state of the art optically, certainly usually with a little more cash added to bag some planfluor or planapo optics.

Thr Nikon e800 came with threaded rods you could bolt on so two people would have handles to carry it together.

Hard to believe that for the price of an entry level microscope) one can assemble such of nice piece of machinery.

Finally got a power supply, everything together (CAS not included) comes in at 47ish lbs., Im still skittish about the table I'm utilizing as a workbench as Im pretty sure was not designed to handle that weight... (Along with the Laborlux and a Stereo )

Next up, Ill have to find a decently priced 75w XBO or 100w HBO bulb, but they tend to be quite expensive, any recommendations as far as retailers!?
Also if anyone could point me towards a DIC condenser and prism I would greatly appreciate it :lol: (wishful thinking)

Im not an electrician by any stretch, but this definitely scares the crap out of me.

Had to look it up, that is one beefy microscope

Speaking from almost no experience whatsoever... I have notice the integration of what looks to be composites and or plastics in some of the brands , when compared to the metal alloys from the 70s and 80s., Specially the use of LEDs eliminating the need for those heavy power supplies.

Are all metal tables preferred over wooden ones when it comes to vibration dampening?
