    Engine green

    Brent, Points well taken. What seems to be missing from all the wonderful Ford photos of the time are pictures from departments within the Rouge that were of lesser appeal to supporting Ford brand recognition. I'd love to see company photos of the paint department that show formulating and...

    Engine green

    Keep in mind Henry used that green engine parts paint as a 'dump' for a lot of other leftover paint. The general green color shifted somewhat in several cycles during the production years. What is thought of today as correct is just an arbitrarily agreed range of greens. The general thinking...

    Galvanizing a Brass Screw

    Technically zinc will plate directly on electro-cleaned brass, but in some environments a secondary atmospheric reaction may cause a dark brown/blackening of the finish in a few months. The best result will be a cyanide copper strike on the brass (acid copper will not bond to most brass alloys)...

    Voltage regulator

    You do not have an external field terminal on an A generator. If you removed the 3rd brush, drilled a hole through the case and wired an insulated terminal for connection to the regulator you could use it- providing you know how to wire the rest of it to bypass the standard A cutout which would...

    help with vibrating mirror !

    The mirror vibration problem also often occurs on modern cars when you replace a broken side mirror glass with a cheapo non-factory piece. WHY??- Every object has what's called a 'period of motion'. That's basically the frequency at which it will swing/vibrate when given one impulse of...

    gastank shutoff valve leak at threads- options?

    Something solid other than teflon that forms into place. This works for me. Smash it into the second and third male thread.

    Tonight's Sorting Out Episode - Lighting

    I hate to be the bearer of bad news, but this "fix" creates another, serious problem. The brighter lamp filament MUST be on the bottom and the dimmer one on the top. This makes the driving beam shift up higher, farther out on High and shift lower, less glaring to oncoming traffic on Low beam...

    Alternator Always Charging

    I would respectfully disagree with that completely. The voltage ranges you spec apply to independent external chargers, not factory spec mechanical generator regulators or integrated regulation multi-wire alternators as originally factory installed. If left on for extended time or frequently...

    Alternator Always Charging

    The correct generator/alternator voltage for a wet cell vehicle battery is 7.15V, +or- 0.05V. This was the factory set point for generator regulators that came after the A era. Most old repair manuals for all generator era cars call for adjusting cleaned and repaired mechanical regulators to...

    Oshkosh or Bust - Reverse Camera for Mullins Trailer Problem

    It is also possible that you have one bad diode in the alternator and the output is very 'noisy'. Barring alternator disassembly, you could check this with an oscilloscope. Even if the alternator is OK the 6V 10/12SI one-wire converts have no soft start and put out a rather severe (to...

    LED Headli9ghts, 6v

    The parabolic reflector in an A headlamp produces a parallel output beam to the back of the lens, which converts that to the correct driving beam pattern. Parabolic reflectors re-fitted with LED's no longer have the emissive source closely confined to the focal point. As a result the output...

    Cylinder head questions.

    Rotary tumbling jacks. Used in foundries for post shakeout scale and core removal cleaning of castings. Rotary tumblers are also used when re-maning large castings. They should have been seen and removed. Must have been end of the shift on pay day. As long as they cannot work their way into...

    Volumetric Efficiency

    Excellent question and of course the one-star bandit tagged it immediately for it's validity. The VE becomes a valid quantitative data tool if you are working with a properly calibrated flow bench or possibly with some over-the-top dynamic flow modeling software. Sans that, if you are...

    Leaf springs and shocks

    As to whether you want dampening of spring action to bias from 50/50 in favor either compression or rebound depends on your particular roadways. Do you have more bumps or more potholes?

    tube question

    FWIW, tires and tubes were originally dusted with powdered mica, not talc! If you look at an old NOS tube you see a somewhat sparkly crystalline appearance to the dusting covering the tube. Talc does not look that way. Original reason for mica: Completely resistant to water and humidity. It...

    Is this normal wear? Aluminum cam gear

    You are looking at plastic deformation. The cause is the inherent un-damped shock wave that traverses a crankshaft with no front harmonic balancer. It is only visible because of the great amount of plastic deformation before grain boundary failure your particular gear has. Is it a 'billet'...

    GAV Adjustment + Choke flood

    Let's look beyond the carburetor. 1) Burned or worn exhaust valve seats will cause backfire. 2) Intermittent electrical connections will cause backfire by causing spark misses that pump unburned fuel into the exhaust. Check: Upper to lower dizzy plate connection Armored cable...

    Oshkosh update 3/11/2021

    No biggie. I don't go to Nationals to take bus tours, anyway. Now, if they cancelled happy hour, well, that's a whole 'nother story! See you in Oshkosh!
