Thinking about the current storage capacity of my card index collection, I made a back-of-the-index-card calculation:  

172,000 index cards * 150 words / card [average maximum, using front only] * 1,200 bytes / 150 words [rough average with Unicode encoding] * 1 kb / 1024 bytes * 1MB/1024 kb = approximately 200 MB of text storage

Having it well organized and indexed… Priceless.

With the recent drop of the second season and Halloween around the corner, I was surprised to see the set on clearance at Target for about $30. 

Dr. Miller has tipped me off that the suggested text for his upcoming course An Introduction to Hilbert Spaces will be: 

Berberian, Sterling Khazag. Introduction To Hilbert Space. Oxford University Press, 1961. Reprint Literary Licensing, 2012.

He’s not happy that it ignores measure theory as a means to introduce the Lebesque integral, so he’ll be supplementing that with additional notes. I’ve ordered a used copy of the 1st edition, but there are also versions from AMS as well as a more recent reprint from 2012.

He also suggested that Debnath & Mikusinski was pretty good, albeit more expensive than he would like in addition to not being a fan some of their approaches to topics.

Debnath, Lokenath, and Piotr Mikusinski. Introduction to Hilbert Spaces with Applications. 3rd ed., Academic Press, 2005.

On Wednesday the 6th, I finished up most of the rest of the clean/oil/adjust of my new (to me) 1971 Olympia SG-3 standard typewriter. The carriage was probably more involved than the main body, though the main body seems to have made the most difference to have been cleaned out. 

Surely there will be a few subtle adjustments I’ll continue to make as I use it over the coming days and put it thought its paces, but it’s definitely ready for prime time use now. 

While it functions much better now, its action isn’t nearly as fast as some of my other standards. Somehow it manages to be more ponderous, though some of it may be the tremendous size of the 6 CPI typeface. Maybe increasing the tension on the mainspring will help out here, particularly with the oversized platen.

While I love having a larger face typewriter, I can already tell that I’m likely not going to be using this one as frequently as I do my elite and pica machines with more traditional typeface sizes. It sure is fun using it though. I can tell it’ll be a hit at the next local type-in.

I’m including some revised photos of it to compare with the previous “before” photos.

Tonight I spent about three hours disassembling and cleaning the carriage portion of my 1971 Olympia SG-3. I really love the fact that flipping two levers inside the shell allows the entire carriage to lift up and off for easier servicing. 

The grinding/sticking I was originally getting mid-carriage was due to a piece of the right carriage cover being bent back and over itself. Removing it and forming it back remedied the situation fairly quickly. I cleaned and treated the rear body panels which show signs of rust developing underneath the paint. (Rust on other portions of the machine indicate it was kept in a less-than-ideal location for years.)

Just as I was nearing completion, the draw band managed to slip off its mount and the mainspring’s unwinding broke the draw band at the metal attachment to the carriage. It took a while to remove the old material, form the cleat open, reseat the draw band and then close it back up. Fortunately re-tensioning the mainspring was pretty simple and straightforward.

The platen action is now so smooth that with the variable lever in the open position, the entire platen will spin freely in a way I’ve never seen a typewriter manage before. Sadly it shows that the right platen knob has a small eccentricity, though it’s so minor I think I’ll leave it alone for now.

In cleaning it, I also noticed that the carriage return arm apparently used to be chromed, but it was done so badly it’s all been peeled off at this point. As a result, the return arm has a galvanized appearance which isn’t ideal. I’ll have to consider some options to improve it in the future.

The toughest part of the operation was the insane amount of degreaser (acetone tonight) it took to clean off the margin rail to get the margin sets to work properly. I have a feeling that someone managed to get Scotch tape stuck up underneath the left margin set, and it took 20 minutes to flush it all out. Now they’re as smooth as butter. I really appreciate the easy-to-use form factor of these margin sets.

The hardest part about typewriter restoration is that you’ve got the machine taken apart and in pieces and you’re three-quarters of the way through cleaning it when you’re instantaneously struck with the irresistible desire to quit cleaning so you can rush it back together so you can type on it right now.
