no, it was a very snug fit on the stock Cobra bobbin. fyi, it was 600 revolutions to fill bobbin with #277 Amann.

it is one like this: https://www.ebay.com/itm/326258473298?_skw=bobbin+winder&itmmeta=01JAQKF50DSB1BMDAB33K5AE6W&hash=item4bf6853952:g:fjEAAOSwEFpmMF~R&itmprp=enc%3AAQAJAAAA0HoV3kP08IDx%2BKZ9MfhVJKmiOV2Dtfen4bbj%2FZEM989stGDqKzt%2F63vyM8AQSD137QgkXEXH3OqMFlVG815a71hIPxCrZHtGvCL3ZbRivUKq23UVr48lzUoBvGfZO6I0RQTM5C%2FIzQosRW%2BBTzgZGcPjcRTek%2BN71NkIQFFurFUguXwW0ELkykRXKTwE2MiOBnN1UqBVPi0Ib4w%2Bn6160tFDoRUlEqynWUCYxIVie5k5bH%2B7YAweitpsR4QckI5TCkdkc0kNhPvDx9MhdqFowik%3D|tkp%3ABk9SR6bQvPPVZA made a frame out of aluminum to hold the tensioner the same distance from spool as the one on the Cobra. tensioner was off the winder that came with my 206RB5.

this cheapo winder counts the number of revolutions. got it on ebay. https://drive.google.com/file/d/1Qb2IGX69TvLqn1IBySZpNl7K3bSRVlO6/view?usp=sharing

how about Glue Dots?

thx, will contact them tomorrow as today is a holiday.

their customer service is more aimed at the industry rather than hobbyists. attached is an image of their label from their online catalog.

was purchased on ebay. to be fair the seller did not mention Coates in ad. other sellers are. after sewing a few inches on Cobra 4, left end of machine covered in lint.

was a lot harder than anticipated. this was the second try.
