Can you make this for my customer?

Sorry, not my area. Just glue a piece of filecard material in a bearing,
like a battery post cleaner.

Mike,
If / when we talk today, ask for Joe Jr. I'll explain the situation a bit.
Right now, we are in the quoting stage for the equipment we provide and are
sharing ideas with the customer on how to deal with this particular issue
they think they will have... But ultimately, if I get the project, I won't
be in charge of providing the 'flute cleaning mechanism of choice' they they
wind up with. I'll tell them who to call. :)
