Your Car Engine on an Oscilloscope

Guest mechanic this month started with an article from Ken Barber and finished by Wheel Tracks

0818 engine oscilloscopeWhen an oscilloscope is used by a mechanic to tune your engine, the picture to the left is what one good cylinder looks like during one firing cycle.

An oscilloscope allows you to see the voltage pattern of anything that uses voltage. They were first developed in 1932 and can be great for tuning your old car, even if your car is a 1901 vehicle.

The pattern to the left tells you how well your equipment is working, that produces the spark that explodes the fuel in your cylinders, that gives you car the power to drive down the road.

A…. Indicates the level of voltage the coil produces to make the spark at your plug. That little flat part just below and to the left of ’A’ is the moment your points close.

B…. Is called the “Spark Line” where if working properly as in this picture, should decrease in a smooth action to zero. The little wiggles to the right of ’B’ is the final remnants of the spark being absorbed by your condenser. When this does not happen, people radios and tvs get lots of interference, plus your engine can not be properly ready to begin its next firing cycle.

D… This show when the points close to allow voltage back to your coil and be ready to make the next 25,000 volt spark. That little oscillation between D and C is normal and show the voltage settling down while your coil initially starts it’s recharge.

The distance between D and E is called Dwell and is simply the time adjustment for your points to be closed allowing voltage to your coil.

The distance between A and E is simply a time period that one cylinder needs during one cycle. During that one cycle, four things happen.

  1. The gas and air mixture explodes from the spark at the plug.
  2. The exhaust is pushed out the exhaust pipe.
  3. The next mixture of gas and air is pulled into the cylinder.
  4. Then it is all compressed to be ready for the next big spark.

8 cylinder engine oscilloscopeThe picture on the left shows an 8 cylinder engine, all cylinders doing what they are supposed to be doing with the spark plugs firing with 14,000 volts. If a mechanic sees the 3rd vertical lines at, say, 5,000 volts, then he might pull the spark plug from #3 cylinder to see if it is defective.

If the little condenser oscillation is not there like we can see between B and D above, the mechanic can suspect a bad condenser.

On the right is a normal set-up for connecting a scope to your engine.

Scopes are inexpensive these days and you should not let yourself get duped into thinking this is complicated… it is not. The more you use it and the more you see the patterns, the easier it is to find problems and make your engine run as smooth as possible.

A scope can even be used in one-lungers, so hit Napas and ask some questions.

1913 Board-track racing Indian and 1910 Harley Davidson Model-F motorcycles

On the left we have a 1913 Board-track racing Indian motorcycle  – On the right, a 1910 Harley Davidson motorcycle

1913 indian board track racing motorcycleThis beautiful 1913 Indian board-track racing motorcycle is owned by Skip Weeks of Collinsville, Connecticut. He found a few parts of the engine for sale and decided to pass. Then a call came and he was told 95% of the rest of the engine parts had been found and it was more than Skip could say no too. A friend helped him put most of the engine together and Fred Gonet was given the task of the final tweaking. Fred has a restoration shop in Proctorsville, Vermont. Then, Skip found a business in Canada that built reproduction chassis and asked Fred to put it all together… and this is the results.

1913 indian board track racing bikeThe neat thing about the machine’s destination is not a board-track but Skip’s living room where Wheel Tracks understands it will join a few other motored antiques. Track racing served as the principle venues for motorcycle racing in America. By 1910, rival companies had started to overtake Indian on the wooden speedways. Oscar Hedstrom who designed the Indian motorcycle in 1900, returned to his drawing board. His goal was to design a new motor capable of regaining the lead for Indian. The result of the engineer’s effort was an overhead-valve design; however this could not withstand the extreme temperatures of a high-speed race. Hedstrom’s solution was to decrease the size of the valves and add more of them. Instead of the usual two valves in each cylinder, Hedstrom calculated that four smaller valves would be better able to dissipate the heat. His theory turned out to be correct, and the overhead-valve configuration also proved to be more efficient.

1913 indian board track racing motorcycle engineThe Indian 8-valve debuted in 1911 and was immediately successful on the pine-board tracks. In 1920 an Indian 8-valve set an official world record for the mile, achieving a speed of 114.17 mph, and in 1926 an updated version of Hedstrom’s landmark design was clocked at 132 mph, setting another world record, which would remain for the next 11 years. It is not known how many Indian 8-valves were produced, but approximately six are known to have survived.

On the left is a 1910 Harley Davidson motorcycle. This is not a racer, but a beautiful road bike. It is a perfect replica of the original owned by Fred Gonet.

Harley-Davidson, Inc. is an American motorcycle manufacturer, founded in Milwaukee, Wisconsin in 1903. In 1910 there were 110 motorcycle brands in the United States and 107 years later, Harleys are still alive and well.

1910 harley davidson rear brakeThis Harley is a 1910 Harley-Davidson 30ci Model F. It has 28 X2.5 tires with an Eclipse Knockout front hub that allows the tire removal by taking only one nut off. You start the 4hp engine by pedaling with your feet until the engine fires then engage the rear wheel by pushing a hand control forward to tighten the leather belt. The brakes are the normal “coaster type” on the rear wheel.

Z Car Update

1972 datsun 240z wheel arch restorationAbsent any questions this month, I will give a brief Z car update. The car is a 1972 Datsun 240Z receiving a total restoration. The car had significant rust in the lower body panels and floor. The left side was much worse than the right side.

Work on the left quarter panel is progressing. The rusty inner wheel well was totally replaced. This involved drilling out the spot welds and removing the old panel. Fortunately, well made replacements are available. The new part was an exact fit. With the new inner wheel well in place, the repair of the outer quarter panel could proceed.

1972 datsun 240z wheel arch restorationWe obtained a Tabco rust repair panel. This panel is made of nice thick steel, but the fit is poor. I like to keep as much of the original car as possible. We went just above the rust, cutting the metal out, just above the rust area. We only cut out the rusty part of the quarter panel, and will weld in the replacement panel.

When fitting a weld repair, I do not like straight lines or sharp angles. I find it easier and stronger to have the weld seam a series of curved lines.

The repair panel was carefully trimmed to fit, and will be welded shortly. It will be spot welded along the wheel well, as original. I may also use two part panel epoxy, this will produce a much stronger, more weather tight bond than it had at the factory.

1972 datsun 240z

Editor’s notes….David and son, Sean, will have the Datsun 240Z at the Shelburne Show on Father’s Day weekend. A beauty of a car, as witnessed in the file picture to the left, is outstanding. Hiratsuka, Kanagawa in Japan is where they were built from 1970 to 1973. The 240Z was meant to compete head to head with the MGB-GT and won the race with its great de-sign and relatively low price.

Preserving

globe ball jarsRhubarb!! We are overwhelmed with it. There is just so much you can eat.Friends either really like it or really don’t like it, so I can only give away so much. I would love to freeze some, but the freezer is full. We just have the freezer that is with the refrigerator…no large separate one. We use to have a big freezer, back when I had a big vegetable garden and froze produce along with pigs, beef cows, etc. We even had someone from somewhere in Canada come to the house once a week to deliver bread, English muffins, etc. That was great, but there were always loaves of bread that ended up in the bottom of the freezer, to be found a year later and tossed to the pigs.

ball jar logo dating chartSo, back to my little freezer, which seems to be filled with blueberries, blackberries and raspberries from last summer. It’s so nice to be able to freeze surplus fruit, but I have a problem with using it all. I want to save it for something, I’m not sure what, so now I have to quickly use it all, to be able to put more in the freezer shortly. Unfortunately, there is no room for rhubarb. I must get this feeling of having to save stuff from Gael who saves everything!!! So, it’s rhubarb pies, muffins, coffeecakes and bags of rhubarb left off a friend’s houses. Then, we’ll move on to blueberry pies, muffins, coffeecakes, along with blackberry pies, muffins, coffeecakes, not to mention raspberry pies, muffins and coffeecakes. I did find a bag of currants in the bottom of the freezer that someone gave me a few years ago. They got tossed. I guess it may be time to start making jams again. It’s been a while, but if I remember correctly, I had the same problem with jams and jellies. I would save them for some reason and then end up giving a lot of the jars away. Pickles! Another thing I would save and then throw away the contents a few years later so I could use the jars to make more pickles.

Right now, I’m not even going to think about pickled beets or green beans. We’ll wait and see how many empty jars I have, come August, and worry about it then.

Editor’s notes….. I have the answer Judy, or at least an answer from a guy’s point of view. Just one of those Globe canning jars in the picture above is worth $100 to $200. You can buy a lot of canned goods at Hannafords for $100.

Ball jars, in the common green shade, a wire bale 1910 is worth $400. A cobalt blue model fetches $10,000 or more.

Mason, Kerr, Hero, Atlas, Columbia, Bartow and Willoughby Stopple are names of others. Is there a VAE member out there who collects canning jars? How about giving us more information.

1937 Ford Flatback Sedan

Is this the same #67 in both pictures?  Ken Gypson’s ‘37 Ford has been around creating history for 81 years and still going strong.  Hal Boardman’s diorama proves the car still inspires…

Hal Boardman and diorama of Ken Gypsom's '37 Ford Flatback racecar
Editor’s note…. Ken Gypson will learn about this diorama for the first time, when he gets this issue of Wheel Tracks, in his mail box.

From VAEer, Hal Boardman …

Two years ago the VAE ventured south to Bennington for a Hemmings cruise-in and a visit to our hosts, Ken and Nancy Gypson, in New York. After morning coffee, juice and muffins-to-die-for, we went out to wander through Ken’s barn. The barn holds a collection of autos, large and small. A must see. Among the full sized cars was a ‘37 Ford 2-door sedan. Ken was in the process of restoring the former round track race car. I took a few pictures and then we hit the road.

A while later the VAE had it’s annual holiday party and I chose an exchange gift of a hot-rod model A Ford 2-door sedan. Walking by Ken’s table he said “glad you got that, you are the only hot-rodder here”. By chance, I happen to see a picture of Ken’s restoration project on line, and I put the two together, the beginning of the diorama idea.

1937 ford racer

The following year I campaigned for another Hemmings tour, it was a great time and… I needed more pictures of Ken’s garage and his race car restoration project. Once again, we had a great cruise-in, and visit at the Gypson’s. I wonder if Ken noticed my mission of taking pictures of every square inch of his garage. I got more pictures when #67 made it to our August show in Stowe last year and then, my winter project began.

While my ‘39 Ford project sat in the corner of my garage, I spent time working on the smaller project of a 1937 race car. I gathered models and parts saved from my youth and began the diorama. I found an old 49 Ford kit in my collection that provided wheels, tires, trophies and even that small dog you see lying on the floor, in front of the car. As my project started coming together, an artist friend offered to paint the number on the car and the walls to match Ken’s garage. Pam even made a small leather belt, that was used to wrap around the passenger door post, to keep it closed during a race. Thank you Pam.

I hope Ken can find a small space in his vast collection for the diorama. I hope, also, that he enjoys it as much as I have building it.

Some history now of the racing #67, from a story Ken Gypson had written earlier…

1937 ford flatback 2-doorIn about 1985 my family and I moved to Poestenkill, NY. Just down the road (to my delight anyways) was Wait’s Junkyard. The Waits had a bunch of old stock cars scattered about and a particular ’37 Ford sedan caught my eye. For 2 years I tried to buy the car…no go. In April of ’87 we had an ice storm that knocked down trees and power lines. While I was in the road clearing debris with my chain saw John Wait Sr. asked if he could borrow the saw. I told him he could have the saw if I could buy the stock car. He grunted and left with the saw. Two weeks later I came home from work and there, the ’37 sat in my driveway!

1937 ford flatback sedan racecar

I have been fortunate to be able to get the complete history of #67 from the day it was built. In 1961, Paul Leinbohm paid $50 for the body and chassis from Slovak’s Junkyard in Stuyvesant, NY, and a 1953 Merc engine from Lou Hacker of Rt 20 in Nassau, NY. Before he could drive the car, he was drafted into the army, and sold the car to Paul Visconte of Schodack, NY. Visconte had George Henderson of Niverville, NY, drive it with number 300D at Rt 66 Speedway in Poestenkill, NY.

ken gypsum 1937 ford flatback racerIn 1963, Visconte renumbered the car to 67 (as it is now) and raced it at Victoria Speedway outside of Albany, NY. Ironically, Visconte also ended up in the Army and left the car behind his mother’s house. Gordy Film of Wynantskill, NY, bought the car in 1964 for $300 and raced it at Pinebowl Speedway in Poestenkill, NY, during the ’64 and ’65 seasons. #67 ended up in Wait’s Junkyard across the road from the speedway’s entrance.

Time is Money

My Chrysler minivan got a little rusty over the winter. This vehicle is too old to be worth much, but still practical and useful. It is a great vehicle to make the weekly dump run, go to Home Depot and to run errands with. It is also fantastic in the snow with the all-wheel drive system. With these duties, and with two teenage boys in the house it makes sense to keep it, and I can’t justify replacing it.

The lift gate is really too rusty to feasibly repair. A new lift gate is unjustifiably expensive. At the salvage yard I was told a decent used lift gate would be $275, and unless I got lucky and found a silver one, I would still have to paint it.

I found a van with a totally rust free lift gate, but it had a large dent in it. I asked how much they wanted for this one and was given a price of $50.

I had to buy paint to fix the rocker panels, one quarter panel and the front fender anyway. With a couple hours of work, the dent was removed and the lift gate is ready for paint. A couple hours of work saved me over $200.

Above,

Cat Tales, etc.

Spring! It will come, better late than never! Also, VAE car shows – Shelburne Museum, July 16th and 17th; , The Vermont Antique and Classic Car Meet (formerly, Stowe Car Show) now taking place in Waterbury, August 10th 11th and 12th, just in case anyone has forgotten!

Our Colorado daughter, Martha, has set us up for a trip to Alaska the first week and a half in July. I hope to be able to get some vegetable gardening done before we leave, as we are out of relish and pickled jalapenos – now that is serious. We (hopefully) will be back before the Shelburne Show. My brother and his wife, will be going with us, and Martha.

A friend will be staying here while we are gone as our three cats will need food and company. By the way, I really enjoyed Nancy Olney’s “cat tales”; she and Gary do need more than one cat, of course. We could help with that since we have one that needs taming. Two of our cats go outdoors and back in, about 20 times a day – guess that is my exercise. I’ll just mention cat pans which they use before going out.

Our third cat is really, really elderly and mostly eats and sleeps, first on Wendell’s chest, then my head. O.K., enough about cats. It’s about time to clean up the yard – Wendell has almost all the logs he’s been splitting and stacked in the shed for next winter, so there is now a project for getting ready for lawn mowing – lots of chips and bark to rake up – and haul out. I am hoping the asparagus will do better this year – maybe getting the weeds out would help. I also hope the horseradish will be doing well, as we need to make horseradish sauce for the shrimp Wendell and others (not me} like a lot. That’s it for cats and gardening – for now!

1957 Dodge D200 Pickup

Paul & Barb Wagner’s 1957 Dodge D200

“For 43 years it was our Every-day farm truck. Today it is our car-show truck”

1957 dodge d200Back in 1967, we decided to purchase a truck to support our small family dairy farm in Methuen, MA. The search led us to a gentleman who had a sewing machine business, and a 1957 Dodge 3/4 ton pick-up with 59,000 miles on the odometer. The truck sold for $1,750 brand new, he was asking $200.00 for it. I countered with $175.00 and drove away with the truck.

It was put into use on the farm immediately. We used it to haul milk, cattle, sawdust, manure, it was a great, all purpose vehicle.

1957 dodge d200 interiorIn 1969, my father and I bought a larger dairy farm in Bridport, Vermont. That was 200 miles away from Methuen. The Dodge was a godsend for hauling furniture and farm equipment to Vermont, and then take hay back to Massachusetts to feed our animals there. I would load sixty, forty-pound bales on the truck (2400 lbs.) and drive the 200 miles on ten gallons of gas. Not bad mileage with that kind of a load. Once the move to Vermont was complete, we put 700-800 ‘farm’ miles on the truck each year. The transmission was not right for slow field work so we rode the clutch a lot. After 11 years of this, we had to replace the clutch and when we did that, we put a four speed transmission in. The move from 3-on-the-tree to 4-on-the-floor made it a real farm truck! It was parked in the shop in 2003 when a gale wind came through and knocked the shop down. The shop roof landed in a tree across the road, while the old Dodge just sat there, with only the scratches it had when we parked it there. The truck did its work until 2005 when it would not pass inspection any longer. For the next five years it sat in the machine shed getting dusty. I started it up a couple of times a year to make sure the engine did not seize.

I sold the farm to my son in 2010 and entered semi-retirement. I had talked so much about fixing up the truck, over the years, that my wife, Barb told me there would never be a better time, than now to do it. I guess she had heard it enough….so I did. Little did I know what I was getting myself into.

Three miles south of here, my friend Kevin has a body shop. I pulled everything off the frame. All that was left was the engine, transmission and wheels, which I pulled to Kevin’s with my old John Deere. This had taken me about fifty hours at this point, all my labor and no money. I soon found out this would get reversed! Just finishing the prep work, Kevin had used eighty-five, 100 pound bags of blasting sand.

When I removed the cab from the frame, I found it was set up for both left and right hand drive. There are pop-outs on the floor for the clutch and brake pedals. The dash is the same on both sides. There is an aluminum plate on the right side where I thought was meant for a radio. When I removed it, I found framework for the speedometer and gauges. I considered changing to the right side but then I thought, “Who is going to drive it?”….Not me!, so I left it the way it was.

1957 dodge d-200 pickup

The next challenge was finding body parts. In 1957, 340,000 Ford pickups were made and GM made 360,00. Dodge made 50,000 pickups that year. So, finding the parts I needed, ended in very short phone calls…no we don’t have any. Then I heard about Desert Valley Auto Parts in Arizona. They had three corpses! My luck had changed, I found the two rear fenders, the right front fender and the grill that I needed. It took three months to get the parts but the wait was worth it. Being a life-long New Englander, I was utterly amazed at the condition… no rust at all! I found two box sides in Rhode Island and used Hickory boards for the floor. I chose not to use oak, as I wanted something with knots, but pine was too soft.

There were two safety problems with vehicles from this period that I wanted to correct with my restoration. The single reservoir master brake cylinder and no seat belts. I went to the ‘68 Dodge split system and had to add a regulator to balance the pressure. Lap seat belts took care of the second problem. The paint color is forest green with two coats of epoxy primer, two coats of filler primer and two coats of enamel. The paint alone was $2000.00…welcome to restoration.

The whole process took ten months to complete. Kevin had 300 hours, I had that many and more, but no charge for me, it’s a LABOR OF LOVE! I kept a notebook of the expenses, even after being told not to because ‘I did not want to know’. The project ended up costing $23,380.00. the high-level break-down was $13,000 in labor, and $10,380 for parts ( I did not rebuild the engine or drive train).

In May of 2014, the steering shaft broke in a restaurant parking lot. The steering wheel was in my hands not attached. I decided it was time for power steering, my age demanded it! Driving is much more enjoyable now. My friend, Ed James, did some research and found the steering system from a ‘79 to ‘86 Toyota pickup would work. I added a pump from an ‘84 Camaro and I was in busi-ness.

The old Dodge gets a lot of attention in parades and car shows. We were at the local soft serve ice cream place when a fella came up and said, “ I bet you think more of this truck, than you do your wife!” I replied, “The only thing I can say, the truck does exactly what I ask it to do.” I always say, there is high tech and there is low tech. My truck is NO TECH!

Editor’s notes… Paul told about his daughter slinking down in the seat, out of view of her friends, in the old days when he would leave her off at school. She recently asked if she could possibly get the truck when he made out his will. Thank you Paul for letting us feature your truck and your history with it.

Sounds Good – A Bright Idea

led headlightsOne of the headlights recently burned out on one of my Saabs. No big deal, this happens every so often. A set of premium brighter bulbs costs almost fifty bucks, and I have noticed they do not last as long as the regular bulbs. A pair of LED bulbs is only fifteen dollars more, and these will outlast the car. I decided to order the LED bulbs and try them. They are a direct fit replacement for the standard halogen bulb. Unlike many LED bulbs on the market, these bulbs are an engineered replacement for the incandescent bulbs.

On some vehicles, like my Chrysler minivan, the headlight needs to be removed to replace the bulb. This requires removing five bolts and takes time.

In addition to lasting much longer, the LED bulbs do not generate heat, takes far less energy, and you can actually touch the bulb without destroying the bulb. Interestingly, I noticed both old headlight bulb pigtails were partially melted when I installed the LED bulbs.

I will drive with these bulbs for a few weeks to make sure they work, at least, as well as the incandescent bulbs.

I bought these bulbs from superbrightleds.com. I am very impressed with their quality, selection service and price. They list replacement LED bulbs for virtually every bulb in the car.
