Re: 67 galaxie fuel gauge problem

Sometimes the whole gauge panel has to come out to check instruments. I would try disconnecting the sender unit first and see what happens. Most instruments use a bimetallic that bends when heat is...

Re: Wind wing part 2

I would purchase rivets for the thickness I needed to join and the next longer size just in case. You can shorten a tubular rivet but you can't add too it. The tubular rivets have to set proud enough...

Re: Overdrive experts I need some help.

The operating solenoid is at full power for kick in until the driver lets off the throttle so it can shift. This shouldn't really tax the system too much unless there is a problem with high...

Re: Battery Acid Recharge

When a battery is at full charge, it should have its highest specific gravity with peak acidic content. As a battery gets lower on charge state the specific gravity gets lower too. A portion of the...

Re: Mixing synthetic and regular oil

Aviation is where the ester based synthetics started out for high temperature operations in turbine shaft and turbojet engines. Using mineral oil in them would be a disaster. In reciprocating...

Re: Overdrive experts I need some help.

Just for information. When your governor reaches on speed, it turns the whole system on. The dash relay energizes the operating solenoid so both are hot until it shifts up into overdrive. While in...

Re: Replacing Wood In a '30 Blindback

Ford Dearborn and Ford assembly plants built near all the tudor sedans. The design used minimal wood for the era. Briggs and Murray built most of the fordor sedans and they used a lot of wood. I...

Re: Wind wing part 2

I use extended bits when I have side clearance problems. The long ones are 10 to 12 inches long. When they are that long, a person can bend them a bit off center if you hold the shank of the bit when...

Re: Distributors

The vacuum spark control is more of an advantage if the country has a lot of hills or mountains. It needs the retard under load for that. Any car can benefit some with automatic spark control. It...

Re: 8BA into a 1934 Ford

The 49/51 Mercury set up may work in some early V8 cars. The water pumps may have to have spacers but I've never done it so I don't know for sure. The oil pan is a good fit. The frontal accessories...

Re: Schwalms

If you don't do your own mechanical work on an engine then you are sort of at the mercy of those that do. Engines don't like to set too long without being bedded in. Once they have been run down the...

Re: Hutchin's Horn Adjust

I mixed it up due to old age I guess. It was Reese Hutchinson (not Hutchins) that patented the type of horn back in 1908. He eventually became chief engineer for Thomas Edison. Sorry for the mix up...

Re: Towing a big truck

Re: Hutchin's Horn Adjust

Re: Towing a big truck

Re: Model B Coil Wiring

Points closed equals a hot circuit with magnetism being generated in the coil core. It's going to drop voltage due to the electro-magnetic effect with resistance in the primary winding. The coil can...
