I'm speaking specifically of a 72mm UR Pro filter. The inner ring has two notches exactly opposed to each other...

I just use two small screwdrivers, (did it the other day) but don't do it by yourself, have someone hold the filter on a table while you do it, once you get it started then its easy...
Or... use calipers...

I can't for the life of me remember the name of the damn thing but way back when I used to do some Technical Drawing at school we used to have what looked like a drawing compass but with two needles on it and a threaded central bar with an advancing screw. You could set the diameter exactly and not risk the thing expanding or contracting (in this case resulting in possibly scratching the lens). Grind down the ends a bit to dull the points and I would imagine that you'd have the perfect tool for the job at hand.

However, McMaster Carr sells what they call Heavy Duty Fixed-Tip Retaining-Ring Pliers. I think that what Peter is calling CIRCLIP PLIERS.
The McMaster-Carr info is
5449A93
Heavy Duty Fixed-Tip Retaining-Ring Pliers Internal W/Straight Tip, 1-9/16"- 3-15/16" (40-100mm) Bore Dia
In stock at $18.60 Each

If you are going to do a bunch of this or just want a cool tool for $85, you can buy 5770A1
Adjustable-Arm Spanner Wrench Set with 3 Pair Of Tips
In stock at $86.10 per Set.

FYI We're also investigating mounting a Expodisc in our flip macro rings.

I found some circlip pliers online, but none of them will span out to 67mm or 72mm (whatever that inner diameter is). Those tools you show seem the best. I will probably give the small screwdriver thing a try, but I'm deathly afraid that i'll slip and scratch the crap out of my new $220 UR Pro filter.

Good luck with your investigations! In the meantime, we'll rig up our own...

By the way, it's funny to walk into a U.S. hardware store and ask for "circlip pliers." they looked at me like I was crazy.
This type of thing is only understood by Industrial Suppliers

Need a "Plunger fot my loo" and you might find it at a Hardware Store...

Wags, I got your Hoya set and the bugga ring is on their tight. I pretty much ruined the +1 as a guinea pig, but they are the hardest retaining rings I've ever dealt with!
This shouldn't be that difficult. Why the hell are they on so tight from the manufacturer, I wonder?
