I've always wanted a distributor tester. The Sun units can do a lot more, but they are huge and too pricey for my beer budget.

I found this Rotunda on market place. Gonna need some work, but the price was right and it's relatively small.

I was taught how to test and “recurve” distributors on that exact model. I’d love to get one for my workshop and your post reminded me that I need one. I got an AS degree in automotive technology at Citrus College in Glendora California along with another AS in Applied Sciences. I bought a recurve kit or two for my Mopars that came with different weights and springs. Thanks for reminding me!
 
Nice.
 
We have one at work. It gets used everyday.
 
I'd love to find a schematic/parts manual/operation manual for it.

I saw it had a paper capacitor in it. I want to change that before I light it up so I don't roast the vacuum tubes.

The housing clamp was froze, I just got that freed up.

The vacuum pump belt is loose, so I want to tighten that.

The motor and speed adjuster spin free, so that should be fine. The vacuum gage reads +/- 1"Hg on 2 other gages.

I'll keep you guys updated.

I do mine on the car with a dial back light and a 1980s Sears engine analyzer. This will be so much easier for small blocks. I have to figure out how to adapt it to electronic (Mag pickup) and Pertonix (Hall Effect sensor) distributors.
 
I could never get comfortable with just revving the hell out of my motor to try and capture the curve, so I always wanted one of those machines or thought about building my own, but it would be used very occasionally.
 
Just bought a service manual for the Allen version. Hopefully it will answer some questions.
