Lamp nipple too narrow for lamp shaft - solution?

Hi All:

I'm adding electrical wiring an old wooden lamp (bought overseas decades ago) using a standard lamp wiring kit. The problem is that the lamp's hollow shaft is too wide for the standard lamp nipple. The nipple fits in the lamp shaft but the harp wobbles around and is not secure at all - see pictures attached. Can anyone recommend a solution here? Do I need to buy some sort of expandable nipple to get a tight fit between the lamp harp and lamp base or perhaps a different lamp wiring kit? Any help would be much appreciated.

Thanks,

A little extra room between the wooden hole and the light kit is not a problem.
You cannot increase the rod size as the light socket won't fit.

You've got an inch of threaded rod hanging out of the lamp.
Is that the amount of rod that will be left there ?
If yes.... add another washer and nut so that it tightens on the wood.
There should be another washer and nut at the bottom of the lamp.

Your going to need to find what thread the lamp is then determine what size of threaded fitting will fit the wood lamp then get a threaded insert.

See the McMaster link!
