Wow.....I love how we think outside the box and come up with solutions to problems like this.....excellent!
but funny you mention about Oster blenders.....I just got another one, like I need it, at a thrift store today....and under the Sunbeam nametag, powerful unit!
So you didn't have to glue it on there it stays put?
Nope its super tight, the ID of the ring is slightly smaller than the OEM part, so getting it over the top was a bit of a challenge, but otherwise it seems to stay put.
