Noisebridge's sewing guild raised money to purchase an automatic, industrial knitting machine for the space. Shima Seiki and Stoll machines were out of our budget and our initial plan was to buy from a start-up, [https://www.kniterate.com/product/kniterate-the-digital-knitting-machine/ Kniterate], which came out of the [https://hackaday.com/2014/02/20/openknit-the-open-source-knitting-machine/ OpenKnit] project.

Those machines were facing production delays and increased cost, so we turned to manufacturers in China for a similar spec-ed machine. We asked 5 vendors for bids via Alibaba/Made-In-China.com/the internet at large and settled on a single system, 52” 7 gauge automatic knitting machine with a controller by Raynen.

We engaged with [https://changshusxd.en.alibaba.com/ Changshu Shengxingda Co, Ltd] for a machine (model [https://www.alibaba.com/product-detail/2023-New-Fully-Automatic-Sweater-Flat_1600063265178.html CHJX-1-52]) at a cost of ~$4000. The base cost of shipping and delivery from China to SF was ~$2000; we incurred some additional fees during this process due to time in port, a customs inspection, forklift rental, and the need for a second delivery attempt.

Here's the timeline of how everything played out.

* April 10 - Initial research starts.
* April 27 - May 5 - Decision-making and engagement with the vendor.
* April 27 - May 5 - Discussions and paperwork with the freight forwarder.
* May 5 - Deposit paid for the machine, production begins; freight shipper contracted.
* May 24 - Machine delivered to the freight forwarder at Shanghai Port. The sailing vessel is MOL Celebration, with an estimated arrival on June 22 in Oakland.
* June 29 - Ship arrival at the Port of Oakland.
* June 29 - July 14 - Container stuck in Port due to a holiday, port backlog, and a customs inspection.
* July 19 - First delivery attempt.
* July 24 - Machine delivered to Noisebridge successfully.
