Re: What is this called?

Broaching is the process of manufacturing precision odd shaped holes including square and rectangular ones. The "D" holes in sheet metal are punched.

Re: Who owns a floor vent, manifold heater?

The photo shows a reproduction of a hot air floor heater that is in my Coupe. It has poor air flow, so not much heat gets into the car. I will be adding an electric fan into the system to force air...

Re: Banger Engine Build

For the record, I previously built a mild banger Model "B" engine that propelled my 45B Coupe to 80 MPH with a stock 3.78:1 ring & pinion. This engine cruised at 60 mph and easily went to 70 MPH for...

Re: Upper door seals for Murray town sedan

Seals were not used atop the doors. Inside the car, a wind-lace molding was used to seal the vertical gaps and gaps along the tops of the doors against drafts. The bottoms of the doors have a rubber...

Re: Scraping noise from engine

I once saw an adaption of a cup type oiler to a Model "A" distributor on this forum. For touring, the oil cup is a good idea.

Re: Need a Project

Restoring a Model "A" needs to be a labor of love because it will cost more than it could be sold for. The equalizer is the value of having lots of fun restoring and using the car. In math:...

Wind Wing Glass - Closed Car

Re: Main Bearing Bolts, Nuts, Washers

Re: engine rpm at idle

In showing off a very slow idle as a characteristic of a good running engine, my concern is metal-to-metal contact in bearings may occur for 2 reasons:
1. Hydrodynamic pressure gets too low because...

Re: engine rpm at idle

Hi SAJ,
Theoretically, hydrodynamic pressure in bearings varies with load, speed, fluid viscosity,
bearing design features and other things. I have not seen or know of any tests or studies done...

Re: engine rpm at idle

When I was running a stock 6V electrical system, I set the engine's idle speed with the hand throttle lever to zero the ammeter. That resulted in a fast idle, I would was greater than...

Re: Soldering and Nickel Plating

Hi Steve,
Solder is lead, and lead was once a common body filler material. A quality nickle plating will have copper first. Copper adheres to lead. By the way, bullets have copper plating!

Re: engine rpm at idle
