I have been looking at replacing a few of the spindles in taps around the house with the ceramic ones.
Essentially these using basin or wall as appropriate (https://www.bunnings.com.au/shaw-mason-chrome-1-4-turn-clockwise-ceramic-disc-basin-spindle_p5050152).
When replacing the spindles in the laundry, the tap handles don't appear to fit on the spindle. The spindle seems to be slightly wider than the hole in the handle, though the screw cap fits onto the new spindle without issue. I tried the spindle on the tap in the shower as well as bathroom vanity and it fit without issue on the spindle. The vanity handles were quite tight though and so just fit on. This is even though it's the same handle type as in the pic attached for in the laundry.
Does anyone have any suggestions on a possible easy way to be able to use the existing handles with the new spindles? Perhaps enlarge the hole a little on the tap handles so they will fit the spindle? I'm not sure why the slight size difference in the tap handle holes for fitting on the spindle. Especially when the thread seems to be the same size as the caps fit.
Cheers all.
