Typewriter Talk / Underwood “Rhythm Touch”/ SX-100 Margin Stop Repair

**Posted by Beachycove** 28-12-2024 13:38:02

I am considering purchase of an Underwood Rhythm Touch standard that has a damaged left margin stop (the thing that slides on the rail). From the pictures I can see on FB Marketplace, the pointer is broken off.

Does anyone know whether the pointer alone can be replaced, or do I need to replace the whole margin stop assembly? In other words, does the assembly come apart or is it made/ welded/ riveted together as a unit?

Beachy,

You might try a search on eBay for "Underwood typewriter parts". Several sellers have parted out various machines and some do not indicate the model from which they came. Some of their offerings are a "grab bag" of misc. parts. Looking through their photos might land you the parts you would need. Seems like the margin stop rail and margin stops are removable from the machines.

In answer to my own question, I’ve discovered that the stop is indeed modular. The pointer curves down under the stop and attaches there with two flathead screws. However, in finding this out I also managed to source the entire part from TB Writers Plus in Dayton, Ohio, at a very agreeable price. The happy upshot is that I will not need to fashion a pointer of my own. It looks do-able, but a DIY part would not look as good as the original, and since the price of the replacement is right, why bother?

I am not sure whether ‘plugs’ are approved on this site, but TB Writers is well worth checking out for those on the hunt for parts or machines.
