Spark plug feeler gauge/gap setting tool
 

I've been using a nice little gap setting tool for massive electrode plugs. Somebody else sourced it for me years ago and I now want to buy another one - but cannot find one anywhere.

It looks like this:

Any ideas as to where I can get one would be much appreciated.

Sort of looks home made to me.

In all the old tools I've seen, this is the 1st I've seen of this one. Even in all my old PW or Wright tools never seen anything like that. Perhaps it's a repurposed tool from a non-aviation application or a special tool to a specific aircraft model. Why not send the picture to several aircraft museums to see if any of the experts can recognize its origin. May not get you another one, but would be interesting to see where it came from. Good luck.

That tool is a common one .it's a champion Aerospace brand tool sold by Aviall which has now rebranded as Boeing.
its sold as part of a kit but you can buy the .015"and .018" gauge blades seperately

Lantern10 and Westaussielame, thanks for the responses. It looks like you are both right. The T-bar would seem to be a locally made holder for the Champion two-pronged feeler gauge. Interestingly nobody on this half of the planet has seen this stuff before.

I will purchase some replacement feeler gauges and see how to source or create more T-bars.

Edit: just realised the T-bar is there too!

Have walked by one of those several dozen times over the years but never stopped to look at it or use it. Still learn something new everyday. Thanks.
