I'm making one final push to finish rewiring my MGB. I've taken the cockpit wiring apart again and am using my new BB-60 workbench to do a 1-1 scale assembly of the wiring harness. In the process, I've discovered I seem to be missing some of the sleeves that keep the light bulbs for the dash instruments lit at night from falling out the back.
|The tachometer. Note the bulb nearby. That goes into the back of the tach to light it up at night.|
|The rear of the tach with the bulb inserted. The next photo shows how loose it is.|
|The bulb will fall right out!|
|Here's the back of the speedometer. Note the metal sleeve that gives the bulb a snug fit. Why didn't MG make the bulb housings the right size? Because they're British, that's why!|
I need to learn how to use a lathe.
Lathes make cylindrical objects which are symmetric down the center line, exactly what I need. There are Maker Places and Fab Labs nearby with lathes and classes. I might have all the sleeves I need now, but it would be grand fun to learn how to use a lathe and keep that trick in my back pocket the next time I need to do something like this.
Hmm. I wonder if I could create a functional sleeve out of plastic using a 3D printer.
