Starrett Angle Guage Reassembly? No. C183

[Erich Weidner]

Anyone know the assembly sequence for this? I took it apart to clean off the factory machine oil and applied a wax coat.
But I fumbled when I got the knurled nut off and all the parts fell to the floor so I didn't get a chance to see in what order they came off.
This is a Starrett No. C183 Protractor.

Thanks Bruce! It is back in business.

Erich, thank you for posting this. I’ve had one laying around and tried several times to get it to tighten. Appears I was missing the spring washer. Had one in my “washers” bin and now have a working protractor.

And Bruce, thank you!
