I have an odd rattle in my 4A. It lurks somewhere behind the dashboard.
I also have an odd problem with the wipers every now and then they stop working. A quick flick of a blade gets them going again.
Yesterday I had the idea that perhaps they were related.
Today I removed all the parts to enable removal of the wiper wheelbox covers.
When the covers were removed - lo and behold - everything appeared normal (bu99er)
Upon reassembly I dropped one of the speedo attachment nuts.
Did it fall onto the rubber mat - no
Did it fall onto the top of a wire loom - no
Did it fall - yes
Which direction - probably up if I know my luck (not been a good couple of days)
OK, not a major disaster. I'll make another one. What is the thread size. I had an inkling that ot was 3BA.
My newish Zeus book only gives tapping sizes - no other data.
Thankfully I have an old Zeus book. It confirms it could be 3BA.
My thread gauges don;t fit the thread. BA threads are very strange (6BA is the perfect thread shape).
Thankfully I do have 3BA taps - the threads to line up.
10 minutes on the lathe and I have a new nut.
I shall now go out to the car to fit the new nut and expect to find the old nut on the rubber mat.
