Back with another mod,
On my lathe I have found that when using the compound slide, & I have needed to reset zero, the gap between the slide & the handwheel is too narrow for my non too slim fingers to grip the spring loaded calibrated dial so I thought 'got to improve on this'

so having removed the handle I measured up the OD of the knurled portion of the dial for my new adaptators ID, I then machined a piece of aluminium (the correct spelling for our US cousins..check periodic table

) to an OD of 45mm IIRC. This OD was then knurled to provide a good grip when fitted. I wondered how to fix the adaptor & considered expanding the aluminium for a shrink fit onto the original dial, not having a blowtorch I opted for the hot water method & duly boiled up some water in my shop 'tea kettle' & plumpt the dial adaptor in for a few minutes, not having the thermal expansion rate for ally' to hand I opted for guesstimate.. no luck..

on measuring the OD of the dial & the ID of the adaptor I found I had mismeasured the ID..

which confims the adage.. measure twice cut / machine once. Onward & upward Geordie I sez; so I decided to go for a press fit (Interference), I machined the adaptor ID to .003" less than the dial OD.. (ok you purists, I didn't conform to BS4500

but I wasn't fitting bearings

). I machined up a dolly to fit over the dial boss & using the bench vice, pressed on the finished adaptor..sorted

then just a case of refitting the handwheel to the compound, I can now reset the zero point without having a struggle to grip the dial

simple ..but effective!
1st pic original dial.. the rest follow on.. last pic all refitted to slide..
Cheers
George
