How do I tighten the output jack on a Kala KA-BE?

Hi,
I have a Kala KA-BE with a loose output jack. My hand is to large to get inside to hold or tighten the nut that is inside the uke. Is there a special tool for holding or tightening the output jack nut on a uke?

Could you use this tool with some sort of addition to reach the nut?

Is this a "flush jack" where there is no nut on the outside? These are a problem if they are not tightened well when they are initially installed at the builders. If you cannot reach the nut inside, you may have to use Titebond glue from the outside, wiggling the jack to migrate the glue into the threaded part.

I'm not sure if this is helpful, but maybe this Uke Minutes video might help: http://www.youtube.com/watch?v=-Ypj_mhXhss&feature=player_embedded
