Royal KMM KMG Typewriter Feet Spacers Original Smashed Rubber Replaced by [[Phoenix Typewriter]]

Squished rubber feet spacers on the Royal standard typewriters can cause interfere with the universal bar and when they do, they'll need replacement.

This is the same sort of interference seen on Olympia SM3s due to their squished/flattened rubber gaskets, though the symptoms are different.

"Phoenix typewriter. Have a Royal day!" <br /> A slightly different sign off from Duane's usual... :)

They recommend fixing the Olympia SM3 spacer issue with:

Danco 1/2 rubber washer Universal (item #198804, model #88569) -- 00 trade size with 1/2" OD and 3/16" ID. https://www.lowes.com/pd/Danco-10-Pack-1-2-Rubber-Washer/3380002

Michael recommends using 1/4" flat bibb washers with 9/16" OD to replace the rubber washers on the Olympia SM3, which notoriously are squished and need replacement. The general symptom is that the carriage sits low on the machine and scrapes or hangs on the sides of the body beneath it.
