It turned out to be a bit more than just a clean, sandblast and paint. On both buckets, 2 of the 3 headlight adjusting screw retainers were cactus

They ranged from not too bad and reusable,

to mostly disintegrated,

and totally disintegrated and gone missing when the screw was removed

One of the springs was also damaged and 2 of the plastic covers were missing

I stuck the spring on some rod and slowly squashed it back into shape with some nose hair pullers


Squashed it in the vice

All good

Next was the retainers. First cut a 5/16” bolt

Did I say I got a new toy? About 18 months ago, I picked up both a lathe and a milling machine from my brother’s mate for $300!! Both need work but I’ve just now managed to get the lathe running so I can do simple turning for now.
Where was I ....... oh yeh, so I put the headless bolt in the lathe, chamfered a 45 on the end and centre drilled it to allow drilling a hole later

Also chucked up a 6mm rivnut and chamfered the inside, also at a 45 degree angle.

Cleaned both bits up for welding on the wire wheel

The reason for the chamfers was twofold - one was to get the bolt and nut to sit straight when pressed together in my elaborate jig,

and the second was to provide a bit more thickness to the nut to prevent burn through while welding as it’s fairly thin-walled. So after a few dobs of snot, it’s back to the lathe

I turned off the snot and drilled through for about 30mm to accept the 10-32 unf headlight adjusting screw.

Next I chucked up the tap and started threading by turning the 3-jaw by hand and applying pressure from the tap by turning on the tail stock. The next pic is of a later one I did, where I started the tap before welding

The beauty of doing it this way is it’s a lot easier to get the tap to run straight. For the first one I did (I’m making six of the little suckers), after starting the thread, I removed it from the lathe and did the rest in the vice

My cheap tap wrench blew it’s guts about half way through, so I hammered a nut on the end and used a 5/16” spanner to finish off

For the other five pieces, I went the whole way in the lathe - heaps quicker. What was also cool about this was that when removing the tap, you could release the tail stock and run the lathe in reverse


Here’s a comparison of original vs repro

I couldn’t thread the rivnut tool all the way as the thread eventually hit the bolt

I added a couple of washers into the gap, cleaned and primed the area on the bucket where the part was going, and installed the part

I then had to remove the 6mm thread in the rivnut with a 7.5mm drill, to a depth of 11mm, to fit the adjusting screw spring

Bob’s your uncle

It was now dinner time, so I’ll have a think about what to do to replace the plastic covers - I assume they’re there to prevent crud getting into the retainers??
