Sourcing a step wrench

I've never owned a step wrench. It's the sort of little used tool that is only justifiable for a shipwright to own. Also large box spanners to fit over skin fitting backing nuts are in the same category. Sometimes you can borrow such tools from a friendly professional (if you have used their services in the past).

Blimey, half of you are advocating cutting it to pieces - and he only wants to inspect and rebed them! I like to use ring spanners as you can put a rod through the other end to get a bit more oomph - combination wrenches just don't work as well. I only butted in because when I did a couple of mine, they had screws through the flange into the hull to further prevent rotation, so I suggest you scrape off the flange to check before ripping a messy lump out of the GRP.
I tried loosening an exhaust flange bolt with a ring spanner augmented in the manner you describe, while crouching in a very cramped space underneath the cockpit sole, behind the engine of a UFO 27 It slipped and nearly took my eye out!

Alternatively, you could ask a professional where he got his tool from.

Resurrecting this thread for another question or three.

Of those that had a step wrench made, how did you size the grooves? Dis you just take one example of a skin fitting of that diameter? Did you ever find it didn't fit a skin fitting of the same size from a different source?
