It’s the weekend again and back to the mirror conundrum.
I worked out the grub screw thread using a thread gauge and ordered some shorter screws. The originals are 6mm x 6.5mm. So decided to try 6mm x 6mm and 6mm x 5mm. However upon trying both options the door still wouldn’t clear the mirror.
So back to the bracket and see how we go
As can be seen above the screws are proud and causing the issue
So the best option appeared to be to grind one of the original screws down to a correct level as it appears 6mm x 5mm are about the shortest available. To make things easier the screw was inserted into a nut and locked with another screw to allow an easier grinding operation.
Once the grinding was done and the threads cleaned up it was time to fit them to the bracket.
This now allowed the screws to be tightened with the right clearance to allow the door to shut.
Next step is to fit the arm and once again check the door for closure
As you can see there is a bit of paint damage from where a mirror was previously fitted, this will be touched in when the weather warms up a bit.
The fit was good, so the mirror head was attached and initially adjusted
Looks pretty good with the two mirrors and will help safety wise.
Finally bit the bullet and carried out a compression test on the Model A
Bought the compression tester from Amazon, can’t beat that for value, please click my affiliate link below (all helps :))
However the Model A needs an adaptor to fit the cylinder head as you can see below
First step removing the spark plugs
Once the plugs were removed the adapter to match the compression tester to the cylinder head was fitted. (purchased from O’Neill Vintage Ford here)
Time to start the test
On to the results
As you can see the results are very even, which other than a reasonable base figure is really the desired result. The Simmons Super Power Head will increase the compression ratio above the standard 4.22:1, and offers a claimed 5.5:1. So a higher figure is to be expected if the engine is in good heath.
After increasing the value of the Model A (at current prices :)) by adding fuel, it was time to head off for a run, taking advantage of the nice weather and the fact that the roads haven’t been salted as yet
The Model A has an early Ford juice brake setup rather than Henry’s original mechanical system. The car is exhibiting a bit of a brake pull under heavy braking and left front brake drum is a little scored.
I was given a drum a while back that is marked “cracked” so decided to investigate condition.
The drum has been stored in the shed for quite a while, so being cast it’s a bit rusty
Had a go at cleaning up and removing the majority of the rust
What seems to be the original wheel bearings seem to be still in place and in good shape.
Part numbers appear to be visible on the drum
Next step will be to run the drum up on a lathe to further clean the braking surface and check for cracks. But so far so good
Air jack saving time and effort once again, you can see them here at Vevor
Was using a Mann filter on the Mike’s oil filter kit, article here on fitting the kit
Moved to the Bosch filter purely on a cost basis, these filters are a version of the Ford EFL90 used on the Pinto engine
Once the oil change was completed decided to inspect the oil and filter as the babbitt engine, (if the original), is over 90 years old and not the quietest!
Starting with a magnetic search in the drain bowl which came up all clear, followed this with the microwave test. This involves taking a small sample of oil in a container and running the microwave to see if any sparks result from metal present in the oil. Again all seems to be clear.
Next operation was to split the oil filter canister, didn’t make the best job of this part and introduced a little bit of metal and paint around the top edge. Wasn’t terribly worried as the folds are where the interest lies and this isn’t exactly scientific.
Once apart and fanned out found it to be pretty much clear with the exception of the expected small amount of sludge. SAE40 is the lubricant used and is a non detergent. The oil pan and pump were desludged not long after purchase. Past oil pan adventures can be found here. To help matters the oil filter kit and regular oil changes have been instrumental in keeping things clean.
So to sum up, perhaps a few more years left in the current lump (touch wood!)
