O.K.
If I could get an MLA casting the right size for my machine (which would be the right size for yours, too), I would dive into machining it to make a cross-slide with the rear T-slots.

O.K. Failure analysis was the purpose that Transitron used back then -- since they had few competitors to analyze anyway. :-) About the only competitor at that time was Texas Instruments -- and while they competed in the actual transistors and diodes, they did not seem to in the potted assemblies.

O.K. I've done the download (and am thankful that they have PDF in addition to ".DOC"), and I've now sent off an e-mail to see what he might be able to turn up.

It takes a lot of picking to get the swarf out, so it is easier to keep it from getting in in the first place. :-)

I was surprised to find the holes already in place and tapped for the taper attachment on my machine.

O.K. That is the one for which my metric threading gear set was made, based on the photos in the instruction sheet.

Indeed. you *might* have to make an over-tall holder to deal with that problem.
Enjoy, DoN.
