Acquired Solari #606 elite typewriter erasing shield, letter counter, line counter, 8 inch ruler by Solari Manufacturing Co., Los Angeles, California
A curved metal typing ruler for a variety of purposes including:
* curved erasing shield (especially useful for carbon copy packs to prevent carbon transfer)
* elite spacing letter counter
* line counter
* 8 inch ruler
Amidst all the typewriter paraphernalia I come across, the curved typing shield doesn’t get enough of its due. While it has some useful measurement functions, its primary functionality is as an eraser shield for erasing errors in carbon copy packs. You would move the carriage to the far right or left (to keep eraser crumbs out of your segment and machine), place the shield behind the first page and then behind each subsequent page to erase the errors from each one at a time. The smooth, curved aluminum would allow you to erase without causing the carbon papers to transfer smudges to the pages behind the shield. 

The curved ruler comes with a convenient tab (here labeled “Elite”) for grabbing with one’s thumb and forefinger for placement into as well as removal from a carbon pack. They obviously came in both Pica and Elite versions to cover various typewriter typefaces. 

Our friend Joe Van Cleave cleverly uses one to cleanly tear off paper from his Kerouac-like rolls of typing paper.

Acquired 100% New Zealand Felted Wool Typewriter Mat by ZOMONETI (Amazon)
MOHOM 17" x 13.5" Wool Pressing Mat 100% New Zealand Felted Wool Ironing Mat Pad Blanket for Quilter, Sewing, Quilting Supplies and Notions
I’ve been looking for a reasonable and inexpensive typewriter mat for a while. There are lots of wool options out there and even some with thin rubber layers to prevent your typewriter from walking across your desk. 

I had appreciated the ones I’ve seen in Gerren Balch’s YouTube repair videos for The HotRod Typewriter Co. which he also uses on his workbench, so I asked him his preference. His reply was these 100% wool ironing pads in 17 x 13.5 x 1/2″ form factor for about $15 on Amazon. He said “it’s soaked up 5 years of everything I do and it still looks like the day I bought it.”

The company has some square 13.5 x 13.5 options, which might be better for smaller portables, but I figured that the slightly larger version for both my workbench as well as for my larger standards would be more flexible. Since the price was half of what I’d seen from other vendors, I jumped on it and bought two: one for my workbench and another for my typing desk.

They’re definitely thick and high-quality. On my noisiest table, they definitely make a difference. They prevent some of the typewriter walking my worst rubber-footed typewriters have, but I’ve also got thin sheets of rug pad gripper that I’ve used before if things get out of hand.
