Prime Failure

The table loom came with a rusty reed. Having spent a lot of time de-rusting the Dyer & Philips reed – and spent a lot of time renovating the table loom already – I didn’t hesitate to buy a new stainless steel reed. I didn’t want to wait!

What to do with the old reed, then? I asked on the Weaving Facebook group for alternative purposes for a reed… and straight away got lots of suggestions on how to de-rust it to use for weaving. Hmm, not what I was asking, but they were trying to be helpful.

Then I picked up a 12dpi free old reed at the guild that I could use on the Dyer & Philips – giving me more yarn options for that loom. I figured if I was going to de-rust that one I may as well do both.

Paul had suggested going to an auto shop and get a larger bottle of rust converter so I could soak the reeds rather than painting it on. They had a spray-on version that contained a primer. The idea of having a thin coat of primer to protect the reed sounded good, so I went for that.

I was SO wrong.

First, I had the reed lying on newspaper. The spray dried onto it, clogging the reed so badly I had to get Paul to use a rotary wire brush on a drill to get the paper off.

Then I reapplied the spray. The remnants of the first and the second coat didn’t go on thinly or consistently, instead leaving bare, rusty patches and globs of primer. I managed to scrape the bigger blobs off, but once I realised that there were bare patches I decided to strip it off and go back to using the old rust converter.

The paint stripper softened the primer, but didn’t dissolve it, so I just wound up with a reed covered in sticky, softened globs of primer. At this point I gave up.

A week or two later I decided to try one more experiment with the smaller reed. The spray advised using acetone to clean up, so I soaked the reed in that. It removed most of the primer… and the coating on the strings that hold the dents in place. The string didn’t come off, thankfully. Most of the primer was gone, but there was a residue left that I am now scraping off each dent with a knife.

So many, many hours labour later I have ruined the longer reed and, hopefully, saved the small one. Though it remains to be seen if the scraping will roughen the small reed so much it wears through a warp.

The old reed from the table loom will get used for something else – maybe a garden ornament. Something a climbing plant to run along, or for water to trickle down.

Lesson learned: never de-rust a reed with a rust converter containing a primer!
