You will probably get an earful from people telling you how knurling is a bad, outdated, waste of time, why don't you do it the right way, etc. but it does work for a while. I have one of those expanders but I have NO idea where it is, sorry. Have you considered the old "skirt expanders" springy metal things that go up inside the piston? They show up online sometimes and also in boxes of old stuff.
