Sewing On-the-Go

If you love typewriters and mechanical things it's natural to like multitools. When you have a screwdriver, can opener, scissors, tweezers and toothpick in one tool you are ready for anything the world can throw at you. I personally love Swiss Army Knives for their design and quality. I also love that there is a vibrant collecting community and an equally strong DIY modding ethic.

Absent in most SAKs is a sewing kit. I know there are some sewing-themed knives made, but without getting into the ins and outs of Victorinox and Wegner and the custom sewing knives made for Bernina, I thought I would try making my own sewing kit in a small SAK.

The first step was to define the problem. I wanted to have a Victorinox Classic SD (the smallest and cheapest SAK) with a full tool compliment including tweezers and toothpick and a place to store some thread, a needle and three buttons; two shirt and one sleeve placket. This, in my mind, was the bare minimum for the kit. Most sewing kits include scissors, but since the SD has a very nice set of scissors already.

From there I sat about thinking about the design. The tweezers and toothpick (T&T) would need to move to the same side. I designed a scale that allowed them both to nestle on one side. The other side of the SAK was free for the sewing kit. The scale itself would serve as a spool for the tread and the needle would held in place with an elastic band.

I got into TinkerCad and came up with these designs: 

A couple of 3D test prints, a little fine adjustment, and a final print:

This is deceptive. The smooth surface is a result of sanding and then spraying with flat black. Then I waxed the paint. It seems counterproductive, but it gives the paint a really nice feel. The elastic band holds it all together. Undo the band and then:

The needle and the thread is revealed. Remove the thread and the access to the buttons is revealed.

Now this little set is ready for all your fashion repair needs. The knife functions still work and overall it's thicker than the old SD, but I think that the thicker scales are more pleasant to use. I'll keep working on iterations. I don't like the idea of the needle not having a more secure storage place. Also, if I could eliminate the elastic band everything would be more secure.

Pinhole MG Filter Adapter

A few months ago a friend gave me an old set of Ilford multigrade filters he used in college. He thought I would get some use out of them in my home darkroom. It's nice to have this set. They are good for a couple of really cool contrast techniques in darkroom printing on multigrade paper. It can really save your bacon with a difficult print.

I wanted to also use these filters with my pinhole camera and multigrade paper. The contrast with the paper negatives can be a little extreme and these filters can tame contrast. However, my filters can't easily be taped to the front of the camera. I had to devise a method to hold them.

The 3 inch filters are designed to go under the lens on a darkroom enlarger. Each filter is mounted in a plastic holder that slides into a corresponding mount attached to the enlarger. I pulled out my calipers, did a little measuaring, and crafted a design in Tinkercad. A hours later and I had this design:

I decided to print it in two pieces on my Monoprice Mini Select and use a fair amount of cyanoacrylate. The grippy bits were printed with the flat side down and the larger filter holder was printed standing up. Because of the tight tolerances required in the filter holder, I didn't want to deal with internal supports. There would be too much friction when I try to install the filter.

This camera has a 90° angle of view and several iterations didn't take this into account. In the end I guessed about the diameter of the cut-outs. The corner of a sheet of paper was a perfect tool to see if there was any obstruction in that 90° angle of view. It looked good.

All of the filters slide nicely into the holder and the fingers grip the bezel around the pinhole. It's sturdy and easy to use.

The next step is to try out the filters with a paper negative. Maybe I'll be able to tame some contrast.

Typewriter Mentor

Last Thursday, my student teacher graduated and I gave him this typewriter as a gift:

Oooh boy, that's a shiny typewriter.

With Marie Kondo whispering in my ear, I stuffed my heart with steel wool and tin foil and made some decisions about my many collections. A few weeks ago I culled the typewriters, keeping the ones that brought me the most joy. Before that, I decided how many slide rules you need to have a collection, but not an obsession. Days before that, I asked myself if I need three of the same Swiss army knives?

The process continues, but I am sure that Joe (my student teacher) will enjoy this typewriter as he begins his journey in teaching.

New for 1947..the OPTO-ELECTIRC INTERFACE

No, it's not a typewriter. Imagine an alternate past where this might be on your desk:

Pretty cool, huh? I took an old desktop mouse and created a 1940s-inspired Opto-Electric Interface. The body is made from basswood and the buttons, screen and screws are all from the hardware store. The vacuum tubes are dead ones that I save every time I service my old TV. In reality I have a big bag full of dead ones that I needed to do something with. I 3D printed a tube holder that would fit in the insert. The screen is also from the hardware store.

The product tag is a toner transfer onto an old bit of disposable aluminum roasting pan roughed up with some 0000 steel wool.

The electrics were dead simple. Move the switches from the PCB to the external ones. I did mess up the traces while I was removing the old switches. In the end I soldered the switches directly to the appropriate IC pins.

You can still get winkle paint and it is a challenge to use. I imagine on warm days it works quickly without a lot of intervention on my part, but is has been cool. Compounding the trouble, I decided to paint the body it was cold and rainy out so you could just imagine me standing in the garage with a hairdryer trying to get this paint to wrinkle.

The body still needs some weathering and aging, but it's wonderfully large and definitely feels like something old.

This proof-of-concept is the first stage in a larger project for a modern computer that has this aesthetic. It will have dials, switches, and lots of knobs. Fun!

Door Prize Winners

Deep in the sub-basement of Magic Margin HQ our UNIVAC has been running the numbers and has identified the three winners of the 7th Phoenix Type-In Door Prize. We had two lovely typewriters to give away along with a copy of Richard Polt's new book The Typewriter Revolution. So without further ado...the paper tape reads:

The Olympia goes to Cameron!

The Remington goes to Candace!

And the book goes to Sierra!

Congratulations to everyone who won. I will contact the winners personally over the next couple of days. I hope you had fun at the type-in. It was certainly exciting to meet so many new typewriter fans. I want to thank all the kind people at Changing Hands and First Draft. Without their continued support we couldn't have so much fun looking at typewriters.

I'll post some pictures in my next post.

7th Phoenix Type-In

Get ready for the 7th Phoenix Type-In at Changing Hands and First Draft Bookbar in Phoenix! August 20, 1-4pm. Bring a typewriter and digitally detox.

Happy Typewriter Day 2016!

I hope that you have a great typewriter day. Keep those fingers to the keys.
