How to replace a right treadle cable on an AVL PDL

I was weaving along on the Birthday Blanket at a good clip when the right treadle cable broke. This was frustrating, but I take it as a sign that I’m now a “real” weaver. Though as soon as I type that, I hear Laura Fry in my head saying, “Not until you fix it, you’re not.” Fair point, imaginary Laura, fair point.

Broken cable

I ordered a new cable from AVL and the following steps show how I replaced it. My loom is an Production Dobby Loom built in 1984. If your PDL was born in another year, these steps might not work for you.

First you need to loosen the set screw on the collar holding the cam shaft in place.Loosen set screw

Then slide the shaft out. (No sniggering, I can hear you!)IMG_3127_2

Next, unscrew the three screws holding the cam on.IMG_3129_2

It is a good idea to take a pencil and mark how the cam lines up before you remove all of the screws. This makes it easy to line up later.IMG_3141_2

The plug end of the cable is held in place by a ring of metal with a slot in it. The hole in the wood is big enough to put the plug and cable through, the ring with the slot covers part of the hole, effectively making it smaller.IMG_3143_2

It is a good idea at this point to measure your replacement cable and make sure it is the same size as the broken cable. (Ask me how I know…) And yes, I am wearing a leopard-print polartec adult onesie. It’s cold in my house; don’t judge.IMG_3144_2

Using a screwdriver and a hammer, gently tap the metal ring until the slot just barely clears the hole in the wood. Do not pound it all the way out, that would make it harder to put back in place.IMG_3145_2

Now you can slide the plug end of the cable out of the hole.IMG_3148_2

Reverse the previous steps to insert the new cable into the cam and attach the cam back onto the loom.

Take the cable up and OVER the cam.IMG_3153_2

When threading the cable down to the treadle, make sure to go over the wooden pulley. If you fail to do so, the cable will rub on the metal rod the pulley rides on and break again soon.

And viola! You’re back to weaving.IMG_3119

Friday: Columbia Gorge Fiber Festival

I had a wonderful time at the Columbia Gorge Fiber Festival. It’s a new festival, I believe this was it’s fourth year.  It was small and had a great vibe, reminding me quite a bit of the Madrona Winter Retreat in Tacoma.

Friday night, there was a book signing with all the teachers and authors attending the event. I had the pleasure of meeting another Storey author, Lea Redmond.

IMG_2998She wrote Knit the Sky, which is about applying the creative process to knitting. It’s an innovative and lovely approach. In one project you use a scarf as a weather journal, in another you track the growth of a child. My favorite was the moon cowl. Half is white, and the other black, and you adjust how you wear it to match the current phase of the moon. Here I am wearing the cowl in the half-moon position.

IMG_3001Judith MacKenzie, my first weaving teacher was there. It felt full circle to have her there, sharing my journey from non-weaver to author of a newly published weaving book.

IMG_3021Another full-circle moment was re-connecting with Sarah Anderson. Once, traveling back together on an airplane after teaching at the Golden Gate Fiber Institute, she quietly confessed, “I just sold a book to Storey.” I leaned over and whispered back, “Me, too.”

She finished her book first, but I got there in the end.


The fun and irrepressible Stephanie Pearl-McPhee (aka The Yarn Harlot) decided we needed a selfie, so this happened. I’m impressed she was able to fit us all in there.


She offered to send the photo out to anyone who had Instagram, so five minutes later I had it installed and running on my phone. If you want to follow my feed, I’ve registered as @synemitchell.

In other news, I am back on the writing wagon. Today I wrote for 30 minutes.

Spinning Socks in the Cloud

One of the fun things about working at Google is that you get to work with smart and creative people. The photo below was created with Cloud Spin, a demo project that shows how to use Google Cloud Platform to build services for mobile apps.

The folks running the demo at the GDG conference were bemused when I showed up with my sock and a ball of yarn.

This is my representation of juggling a craft-filled life.


It would have been even more fun if I’d had several unfinished projects to juggle, but I had to work with what I had on hand.

The way the technology works is that you have a set of mobile phones arranged in a half-circle. You jump, and each phone takes a wee bit of video. The app controlling the phones inserts an audio “beep” as a marker when you jump. Then the phones upload the videos to code running in the cloud, which extracts the frame corresponding to the audio marker from each video and compiles it into a single animated GIF.



The team that created this demo did it on a nearly nonexistent budget, in three weeks. I edited the blog posts they wrote about the project. If you’re interested in the technical details and/or building your own version check them out:

Cloud Spin, Part 2: Building mobile apps to orchestrate video recording

Cloud Spin, Part 3: processing video using Google Cloud Platform service

And yes, seeing this photo does make me want to eat better and get more serious about exercising regularly. But you know what, if I wait until I’m thin to do fun things, that might be a long time… and I’d miss out on adventures in the meantime.

P.S. I have totally fallen down on my NaWriDaMo pledge. Epic fail. I blame the wool fumes at the Columbia Gorge Fiber Festival.

Book release day: Inventive Weaving

For previous book releases, I’ve made a pilgrimage to the local bookseller to take a celebratory picture standing next to the book on the shelves.

With my time almost completely taken up with working at Google and spending time with my family, I’m not sure when I’ll have time to get to a local yarn or book store. So if you see a copy out in the wild, give it a pat for me, will you?

Cover for Inventive Weaving

This book is the culmination of four years of work, research, weaving that went well, weaving that didn’t, fear, day jobs, procrastination, more work, and heroic efforts on the part of my editor.

I hope you like it.

P.S. Got my 30 minutes of novel writing in yesterday and today. By the skin of my teeth today, but done!

Columbia Gorge Fiber Festival

My new book, Inventive Weaving, is scheduled to be published tomorrow, though I know that some folks who attended Rhinebeck or pre-ordered the book on Amazon have already gotten their hands on copies.

This upcoming weekend I’ll be promoting the book at the Columbia Gorge Fiber Festival, in The Dalles, Oregon. It’s one I’ve never been to and I’m interested to explore it. There are some great teachers there. Friday afternoon, I’m taking the Knit Smart class taught by Stephanie Pearl-McPhee

Friday, from 4pm-7pm, I’ll be participating in a book signing with all the luminaries teaching at the festival.

Saturday, I’ll demo weaving overshot on a rigid heddle loom from 11:00-11:45, near the registration desk.

Linda Gettman, one of my former students, is teaching rigid-heddle classes at the festival . I’m so proud of her! If I teach someone to weave, and they go on to teach others, does that make me a weaving grandma?

And yes, today’s 30 minutes of novel writing are done!


November is National Novel Writing Month. It’s an annual event where writers pledge to write a novel (40K or more words) in a month. There are websites where you can register and find other enthusiasts, and cheer each other on.

I have never participated in NaNoWriMo, but I’ve always been intrigued. I like the idea of committing to something, and being part of a community of writers. But the idea of writing for speed, at the probable expense of quality, doesn’t work for me.

But this year, I think I’ve found a way to participate. Instead of pledging a word count, I’m pledging 30 minutes a day.

Each day in November, I’m going to carve out 30 minutes and sit my butt in the chair and write. Perhaps it’ll only be two sentences, perhaps a whole chapter. I won’t end up the month with a novel, but I’m hoping to end up with a sustainable habit that can eventually lead to one.

I call it NaWriDaMo, National Write Daily Month.

And yes, I’ve already done 30 minutes today, on something that might, one day, be a novel.
