1929 Model A Ford Sport Coupe Misfire

Upon starting the A today I was experiencing a bit of a Misfire, heard a tracking sound and found a plug arcing out on the advance & retard lever. The car has a Simmons head which means the plugs are in a non standard position. New one on me, maybe the weather? All cured by a little bit of insulation tape. I have a modern cap & leads to fit but I like the old style strips!

 

Memorandum from Ernest Kanzler to Henry Ford regarding Replacing the Model T, 1926 – The Henry Ford Archives

Ernest Kanzler

This memo was probably on of the reasons that Henry Ford eventually replaced the Model T, however it cost Kanzler his job and damaged Edsel Ford’s career.

Under the A!

After painting under the bonnet/hood I took a look at the underside.

I must admit I’ve been putting this task off because it’s not the most pleasant.

I’ve added a few old pictures from a few years back to show the difference!

Looks a bit better now, but will need a few more coats as it’s sucking up the paint.

 

Under the Hood

Doing a little bit of under hood/bonnet painting before the weather gets too cold to get outside. Not exactly concours but looks a bit better. Much more left to do, but as you can see we’ve come quite a way!

Straightening the Front Bumper on the 1929 Ford Model Sport Coupe

The front bumper on the Model A had been bent since I got the car so we decided to have a try and straightening the bar and see how it looks.

As you see after a bit of a wood issue the bumper is now pretty straight.

Once we got the wood situation sorted out we got the bumper back in pretty good shape,

Found the Cause of the Noise on Left Hand Lock on the 1929 Model A Sport Coupe

 

There has been a recirculating grinding type noise coming from the Model A on hard left hand locks since we changed the brake back plates.

Simon and I set off on a road test to pinpoint the noise and Simon nailed it!

The noise was coming from the right hand rear wheel.

After removing the wheel and hub/drum assembly we found a couple of issues.

  1. The back plate and brake drum had been rubbing
  2. The brake shoes have a raised metal edge and this has been rubbing on the inside of the brake

The brake shoe issue was alleviated by grinding the metal edge off the brake shoes

Once this was achieved the drum was placed in the lathe and a small amount of material removed to ensure that the drum and back plate were no longer  in contact.

A final road test confirmed that the diagnosis was correct and the treatment had been a success!

Here’s some photos of the work carried out

Long Promised Ride in the Model A

When I first imported the Model A over three years ago I promised my Aunt Noreen a ride in the car and finally today I delivered on the promise 🙂

Joe Jagersberger (Rajo Joe) Hot Rod Pioneer

img_9761
Joe Jagersberger came to the USA from Austria and began working for Case Corporation in Racine Wisconsin to assist in developing a race car programme.

Whilst working for Case Jagersberger was a regular race competitor including racing at the Indianapolis 500. He continued to race until 1911 eventually becoming victim to a career ending crash after which he spent several months in hospital and resulted in an amputation of his right leg.

Despite his injuries he continued to work at Case as a consultant. He continued to design cylinder heads and other peripherals eventually starting his own company under the famous Rajo brand. The name of the brand was formed from the RA of Racine and the JO from his first name.

Rajo started off by producing spark plugs and various other items. They then moved into producing  performance cylinder heads for Ford Model T and Model A cars.

The first design was the Model 30 which had 4 exhaust ports and one intake port all on the right side of the head. The Model 31 had two intakes on the right and four exhaust on the left. The Model 35C, first known as the “Improved Rajo Valve-in-Head” and later as the Model C had two intakes and three exhausts on the right. The Model A used the stock intake ports on the block. It had two exhaust ports on the right. His Model B two intakes on the right and four exhausts on the left. It came in three versions. The BB featured a higher compression ratio and the BB-R also included two spark plugs per cylinder.

He also offered a modification to the 1941-52 Chevrolet “stovebolt” L6 OHV 15 bolt head, which added another set of 3 intake ports above the 3 originals, to permit adding (an) extra carburetor(s) on a separate manifold.

Jagersberger died in 1952. The company closed in 1980.

Rajo equipment is still very much sought after and command very high prices amongst the traditional hot rod community
