A misplaced obituary
Since there is not a "General Forum" I post this here to note the death of a giant microscope machinist/fine mechanic: I apprenticed for 4 years under Klaus Wirbelauer who was a master machinist from the German apprentice program having menteed (and trained at Karl Kapps) in post WW2 Wetzlar Germany...

Re: Identify this AO Mutant Model 10 Beast from my Boneyard
apo - this is too coincidental - so that it would be applied to last years budget, I just bought (back in November) new Remo Renaissance hazy heads from Steve Weiss.com for those ancient "Slingerland" tympani. While I had the old heads removed, I used a nylon car body mallet and some dollies to remo...

Re: Identify this AO Mutant Model 10 Beast from my Boneyard
AND, yes, PeteM, there are some lines evident in the body of the scope... I'm going to try and adjust the lighting in order to see if they will show up in a digital photo. There's also some evidence of "blending" marks under the paint about half way up the arm just under the co-axial focus knobs. I'...

Identify this AO Mutant Model 10 Beast from my Boneyard
I've had this Fleabay purchase hanging out in my "boneyard/parts" area of the machine shop for several years. I bought it because it was clearly made by American Optical in their factory. and I'm a collector and fan of the Model 10 (my favorite being a beautiful "Phase Star" that came from Clemson U...

Re: Where can I get a ringing table from?
I took some side and top view pics that may help show the clearances that are possible on the Leitz table. By moving the ruler around, I would estimate that a glass slide could over-hang the ringing stage/ turn-table by almost 1/2 inch before it would hit the pillar that supports the hand rest. I'll...

Re: Where can I get a ringing table from?
I love this post! I have contemplated buying one of the Brunel ringing tables so that I didn't possibly mess up my vintage Leitz table! As I recall, the Brunel tables are very reasonably priced.

If that weren't a Brunel created video, I would assume he just voided the warranty by avoiding that little knurl!!!!!!!!!!!!!!!!!!!!!!!!!!! It's like some little ole lady quilters I know... the knurling helps you develop a "slide ringing callus!"

Re: B&L Panfocal Illuminator - Milling a New Lamp Housing
As a further indication of the complexity of the Panfocal condenser/illuminator, by comparing B&L 1958 price lists, a fairly complete 4 objective Model TT ("tri-ocular") Dynoptic would cost you around $670 USD, the Panfocal Illuminator by itself was listed (from the same source) at a hefty $240 USD!

hello dtsh! I love "the enlighten-ment!"

I've got some aluminum square stock that I will be milling to fit and an offshore LED illuminator as a lamp and...

Hans, that does appear to be a similar treatment! I'm glad you showed that... and BramHunting, I do think that someone attempted to polish that portion of the holder since they discovered it is brass.

That's a good idea, especially with the micrometer eyepiece - it has an unusual diagonal X as the moveable crosshair against the background scale.

$29 Fleabay Microscope Poses for Her Glamour Shots
I literally bought this old cast iron Bausch and Lomb in order to slaughter it out for parts - $29 on Fleabay (the shipping was almost more than the cost of the scope!) Due to the cast iron stage, limb, and foot, she weighs in at a hefty 11lbs. An Ortholux I, by comparison, is around 25lbs, but the ...

I suspect you may be correct. That is one of the more endearing characteristics of most American manufacturing - that they would tend to standardize a part to work in different applications.

So, these are Fleabay "salvage" items that I sortuv agonized buying (in order to fancy up a "triocular" B&L Dynoptic).
