The jet in this Gloria lantern Gloria Lantern (Australia) was 0.33mm diameter. When trying to fire it up it kept flooding. I measured the thread on the nipple at 9/64” – 40 TPI (A Model engineering thread but non standard size). Whilst looking through my spare nipples and vapourisers I noticed the Handi Kero-pet looked similar. Dimensions – Gloria Nipple thread – 3.54mm (9/64”) – 40 TPI Diameter – 6.3mm (1/4”) Length- 102.6mm Cleaning rod – 106.7mm Mounting nut - 11.1mm (7/16”) Handi Nipple thread – 3.9mm (5/32”) – 120 TPI Diameter – 6.3mm (1/4”) Jet – < 0.21 > 0.18 mm ( couldn’t measure it exactly) Length- 101.3mm Cleaning rod – 111.2mm Mounting nut – 11.1mm (7/16”) Handi on the LEFT Gloria on the RIGHT The threads were not compatible for a straight swap. Swapped the inner coil, and mounting nut from the Gloria to the Handi vapouriser. Shortened the Handi cleaning rod to 103mm and rethreaded the end with #1 UNF (72 TPI) die. Note: length shortened in steps and checked in position until vapouriser fitted. Nice and bright, no more halo.
