hi yvsa,
i wanted a solution not requiring removal of the chape from the scabbard, so thought of the bells.
they're about 1/2" - biggest i could find that were reasonable - next size the local ornament store* had were about 1.5" & way too big. made hole in center of cross-slotted end of bell big enough to allow the chape tip to go in all the way by experimentation, filled the whole inside with epoxy steel and stuck it on the end of the chape, having roughed up the brass of the chape with my trusty bastard file to improve adhesion. wiped off excess epoxy & i can just barely see the grey line. they make copper colored epoxy sticks for plumbing which might work also.
i'm a light user & carry the kukh's on a baldric when i do & have not as yet knocked one off, tho i've not had any impact on the bell things to speak of (except my leg, which now is unpunctured). bells have a small loop that can take a small split ring & a tie-down thong - which i have not implimented as it would prevent me from swiveling the scabbard.
soldering would probably be more secure. i've now bought a small blow-torch & have made & silver-soldered a few bits & bobs for my dha restoration project so might solder next time i get an HI or knock off a bell.
*- lechlade (where kate moss lives) is about 3 miles by road (2 mile walk along the thames) & has a dedicated 12 mo. a year christmas ornament store! wierd! (he tells me he does most of his business over the internet)
dha & belled kobra. dha scabbard was split, copper chape was disintegrating & last 6" exposed point due to missing wood. reglued wood, added reenforcement strips over joint & replaced missing wood at chape end. sanded like heck, stained & added new copper chape, slightly crumpled as in original, added copper bands at throat and midline, replaced degraded rope baldric & added braded bands & gave all a good coat of exterior varnish. after done soaked it in mineral oil for a few days to revitalise wood. have not touched blade other than to give it a steel & strop to bring back the edge. 1st 6in or so has silver inlayed scrolling on sides and along the top edge. dha was taken from a japanese officer by a british gurkha officer in burma (the brit was probably carrying a kukhri, mebbe what made the jap dead?)
three 'belled' kukh's, and a shot of the silver inlays on the Dha (tip of zira bouk poking out on right)
rest of zira bouk for thos interested (gold & silver inlays):
