Campagnolo Chainring Nut/Bolt Tool?

[djdj]

Does anyone make a chainring nut tool that fits the chainring two-piece nuts/bolts, circa 2010? Not the torx bolts, but rather the nuts/bolts that have the slot that one needs to hold while torquing the torx bolts. The Park tool I see online (CNW-2) does not look like it is designed to fit, and using a screwdriver seems a bit dodgy.

These are the chainring nuts I'm talking about. Thanks in advance!

What I do for those is put a large flathead screwdriver in my bench vise. Then I tighten the outer bolt with the inner one resting on the screwdriver. Doesnt see a lot of torque once the face of the bolt tightens up against the chainring seat.

That makes sense but, unfortunately, I don't have a bench vise. And none of my screwdrivers are a real good fit.

Short stubby flathead screwdriver won't move around much. Pick one up for a few bucks at your local Ace.

I found this sweet tool on eBay.

[edit] Which doesn't fit Campy chainring bolts.

Thanks. I read someone complaining that that it doesn't fit Campag. I wonder if anyone here has tried? There is this similar alternative.

Just tried. It doesn't.

Teeth aren't tall enough.

The teeth on the original Campagnolo tool are about 3mm in height. On this tool they're about 1.5mm. I wonder if I can grind down the body to extend the teeth another 1.5mm...could be a bit tedious with a Dremel tool...

Circling back to the short and stubby. It'd be pretty easy to file/grind down the edges of a flathead, thus making a centering pin.

Thank you. The Super B doesn't look much better in that regard, so my search continues.

I bought the Park CNW-2 and can confirm that it works without modification.

Um, actually no. It's too wide to fit on Record 10 Compact bolts.
