Problem was in the tab brake, but not with the little brake pads as expected.

The four pie-shaped segments that hold the actual brake pads are made from a pot metal-like material.  That material deteriorates and develops cracks,  The metal expand when they crack.  Two of them were pressing hard against the housing of the brake mechanism and prevented its free-spinning when the tab key is depressed. 

Best solution would be to either find replacements for the pie-segments or throw the cracked pieces out and abandon the brake function.  I chose to discard two of the segments that were cracked and file the surface of a third so it does not bind on the housing. 

I'm not sure the two segments I returned to the mechanism are effectively "braking" the carriage movement or not.  To guard against possible slamming of the carriage, I set several tabs across the travel to avoid that problem.

About the time I got this fixed I remembered that years ago I had the same problem with an Olympia office manual from the same area.  At that time I was able to find an entire new brake assembly and simply replaced the old one.

Thank you Laurenz.  I'll get going with the operation and report back.

I Just searched and read a couple of threads on this forum regarding a sluggish tab.

Am convinced my problem is the tab brake.  Thanks to photos posted on earlier threads, I see where it's located.  However, I don't know how to go about removing it.  Another fellow from CT was wondering the same thing a few years back, but I didn't find any follow up to his post.

Has anyone here tackled this problem of brake removal?   If I can remove it, possibly I can replace the cork brake pads, as one member was successful in doing.

Thanks for your input.

typewriterman, your emery cloth suggestion worked like a charm!  Many thanks for that tutorial.  And also for your information about the typewriter's date. 

That starboard knob was stuck fast.  I had to grip the emery cloth wrap close to the platen with a pair of long-nose pliers and use the tender grip of a channel lock wrench to turn the knob.

Here is a photo of the machine I've been calling an SM9.  If I'm wrong about this, someone please inform me of the correct model designation.

By the way, is the model marked on the machine?  The only marking I've found is a number on the underside:  4651867.  Does this indicate year of production?  Thanks.http://i.imgur.com/P1Vg35Xm.jpg

What I mean by the second questions is, I'm having trouble getting a good grip on the platen while trying to turn the knob.

Thank you for your responses.

thetypewriterman - The left hand knob came right out with no difficulty.  The right hand knob is another story.  Do you know if it has left- or right-hand threads?   What is the best way to hold the platen while unscrewing the knob?

I have an adhesive-backed label stuck down behind the platen that will require removal of the platen to clear. 

If anyone here is familiar with platen removal on this machine, I'd be grateful for directions.  From comparison with similar typewriters on e-bay, I'm reasonably certain my Olympia is an SM9.  I have photos on IMGUR, but this is my first post on the forum and my understanding is that I cannot yet link photos.

Look forward to participating here..
