Has anyone done a how-to thread on a brush restore? I see many many threads in my search but they seem to just be results. I have an Ever-Ready boar brush that was my great grandfather's brush and I'd like to get a new boar knot for it.

I guess it's very simple but I didn't want to give it a go without first asking if there might be something that explains or shows in pictures how to remove the current knot and possibly disassemble the handle (looks like two pieces). I really would never be able to replace it if somehow I royally messed things up.

any links to current threads or instructions would help tremendously! Thanks guys
