I've been working on a nasty Regina CX for rothenfield1 the past couple of days. The rusty cogs will take a OA bath very soon. The body is still a toss up depending if the bearing retaining ring comes off or not. I have some before pictures and will post them when I have the after to show the results.

I missed this thread, nice pictoral. I think I will give this a try on couple of cranky freewheels I have.
