Anyone familiar with how to dissemble these? Reluctant to start swinging the hammer!
Even screws are hard to get at.

I posted this step in the link provided....as well but worth repeating. The knob element attached to the rotating arm is secured with a csk head rivet & peened over a retaining washer inside the bore indicated in the photo below.You need to very carefully & accurately drill out the whole rivet (diameter of rivet is 11/64 or .171") on center with the existing rivet so as to minimize having to install a larger replacement rivet......how is the smaller knob adjustment hinge Rivet (?) removed to disassemble springs , etc?
Doesn’t appear riveted but unsure.
The green tinge might be due to oxidation of copper elements in the original paint? I picked the closest powder coat hammertone finish that I could find...but it could have been a shade darker. Once you remove the lower fixed gear assembly by drilling out the 3 rivets, you should see the original unfaded paint color under that flange. If not powder coating......you should be able to get a close match silver hammertone rattle can paint at the big box store....what is the best estimate of what the original color was for these babies? Were they always the same color? Greenish silver hammer finish on mine but decayed so difficult to be sure.
see third photo I provided in post #4....rivet diameter is 11/64" ...an odd ball size hence the reason I machined a new one to the original spec......I see a countersunk steel rivet is recommended, what’s the correct size. 1/4”?
Not that difficult actually....the gear has convenient holes machined into it to allow a punch access...as does the main bracket itself.....I see custom rivets were fabricated for the gear plate, How did you buck the rivet?
I don't recall the size now but if available....for sure.....a steel blind rivet (or monel would be OK)...Thinking quality blind rivet would work here too?
that would be a 4mm rivet by my calcs
