FE engines use a timing assembly very similar to other Ford engines, with the aforementioned cam thrust plate, an offset positioned dowel pin for locating, and a single central cam bolt for retention. The factory cam sprockets were often aluminum with molded nylon teeth for quieter operation. The chains were a link type with single-toothed sprockets. The steel lower sprocket has a light press fit onto the snout of the crankshaft and is located by a single keyway. All current replacement timing sets incorporate this spacer into the sprocket; the spacer, if found, should be discarded during service.

An oil slinger goes in front of the sprocket to reduce the amount of spray aimed toward the front seal.

Sprockets are accurately made, and therefore the ideal length is maintained. In my experience these have proven to be simple and reliable. Link-type timing chains are comprised of multiple side plates woven together and assembled into a chain with pressed and peened pins. The side plates themselves are in contact with the single wide teeth on each sprocket; the pins do not touch the teeth. The design is simple and quite durable, but has fallen out of favor in the performance market over the past twenty years.

Replacement sets use sprockets machined completely from iron with no plastic and thus eliminate this potential problem. Another issue faced by link-style chain systems is that the links are in contact with, and eventually wear into the sprocket teeth.

Unfortunately, imported components of questionable quality and corner cutting in both quality and manufacturing are common. Roller timing sets are the norm in high-performance applications. The ANSI chains are less expensive, and are sold with pins in. It is important to identify which chain you are using because the sprockets cannot be interchanged; the tooth profiles are different. Upon initial use, all chains stretch to an extent because of construction and function of the part.

With the notable exception of Cloyes, timing sets are generally outsourced items—sold under a marketing brand name that is often not related to the actual manufacturing source. Chains and sprockets are manufactured by numerous companies in various countries, and in a wide range of quality.

Chains can usually be identified by miniscule stampings on the links. Rolon from India is a common supplier for lower-cost sets. Sprockets can be harder to identify. Cloyes makes its own, as well as private-label parts for numerous other companies.

I created the electric trike for my friends that might be scared or embarrassed about riding an e-bike, and for me to go as fast as I possibly can around my yard. In addition to his trike not being street legal, there are a few other reasons why Blake decided to create a track around his house.

I also recently built a mini ramp in my basement to skateboard in the winter Blakeside, and I wanted something to do in the summer outside. The shape of my track came about naturally, there is no clear starting and stopping point. I just rode around the two trees, along the fences, and down the driveway. I dug out a couple of berms with a shovel, widened a doorway so the trike fits through the back of garage, and made ramp connecting my front and back yard.

My figure eight track is about ft in length or 0. Once he had the track built, he realized that he was going to need a timer to see how fast his laps around the track were. This situation presented its own set of challenges. My girlfriend wanted to leave a sarcastic product review, saying the Louisville Slugger Radar makes silly boys crash their toys.

So I had to come up with a safer, hands free, and eyes free way of accurately collecting the data racing around my track. In a second videoBlake follows up on how he finished the project using reflective beam sensors and installed additional sensors on his track in order to calculate his speed as he passes by them.

Because he has more than one loop on his track, the various sensors can also determine his lap times based on which loop he completes. And for anyone still on the fence about the advantages of turning your yard into a race track and building a digital timer for it, Blake points out another benefit to his decision.

Some have a do-it-yourself mentality and are eager to build their own chip timing system, but may not necessarily know where to begin. After watching other companies set up timing systems at races,most interested professionals are familiar with the basics of race timing, but the inexperience of managing a system may create some headaches when you begin building your own system. This short guide will point you in the right direction and cut down on those headaches.

Readers - The reader will scan tags as they cross checkpoints and finish lines and is the brains of an RFID system. Antennas - The antenna in an RFID system serves as the crucial piece that communicates information between tags and the reader. Antennas can be categorized by their frequency, usage indoor or outdoor, mounting type, and polarization. Race participants will wear one to two tags, either on their bib, ankle, or shoe, depending on the tagging method.

Connector type, length, and insulation rating are all very important considerations when determining which cables are right for your system. Server - A server hosts your software and stores all of the RFID data coming in from your race timing system.

Timing Software - The software processes information and tracks time stamps of participants during races. If you are building your own solution, you will need to have knowledge of software development, or have a software developer build your ideal software solution.

Reader manufacturers provide a software development kit, or SDK, that can be a good starting point when constructing your custom software. If you are a software engineer or have hired a programmer, you can choose from several popular RFID readers:.

If you wish to avoid integrating with the reader, Impinj offers software that can read RFID tags and output data in various formats e. USB readers can connect directly to a PC and have short range antennas so that only the desired tag is encoded. There are several different types of antennas, so it is important to choose one that is rugged enough to withstand the demanding conditions of a race. Rugged antennas are generally rated IP 67, which indicates that they can be used outdoors in case of rain or high humidity.

There are two different types of antennas used in race timing, panel antennas and mat antennas. Panel antennas are mounted on a tripod or truss at the finish line, while mat antennas lay on or near the finish line for runners to cross over. The type of antenna you choose depends on your specific race, especially the width of the finish line and the number of participants.

Some timers use both types of antennas for their races to ensure reads are captured from multiple angles. Depending on your hardware configuration and the set-up of your system on race day, the RFID cables you need will vary in terms of length, insulation rating, and connector types.

It is important to ensure that cables are not an afterthought as using the wrong cables can lead to a high amount of loss in power, resulting in missed tag reads. As a cable becomes longer, it will experience more loss. You can combat that loss by using a higher level of insulation for the cable. There are three main levels of insulation:, and The higher the insulation rating, the less energy will be lost; however the cables will also be thicker and less pliable, which could be a problem for some race timers.

If you would like to better understand the relationship between cable loss and length, read this article to view the cable loss chart. Note: the reader cannot be much more than approximately 50 feet away from the antennas, which limits the cable length.

There are a few types of RFID race timing tags that provide excellent read range and are suitable for a variety of environments.The Freelap Timing System is an easy-to-use, fully automated timing system that is designed for a wide variety of training scenarios including track and field, football combine, downhill skiing, downhill mountain biking, swimming, and virtually any sport that involves speed training.

Freelap can be used to time fly-in sprints, splits, block starts, tempo runs, recovery times, laps, long and triple jump runway speed, football combine 10 and yard dash, agility patterns, to name a few. It is used on the track, football and soccer fields, basketball courts, mountain bike paths, ski slopes, swimming pools, and hockey rinks.

Freelap can be set up in less than a minute. Simply turn on the transmitters and place them on the track or field and begin training. Coaches can set up a 30 meter fly-in sprint in the time it takes them to walk 30 meters. Freelap is designed to support both the individual athlete and team training.

Masters and elite athletes who coach themselves now have the ability to accurately time every sprint of every practice. Coaches who train a team can collect data on all their athletes. The Freelap components are small and lightweight and many configurations fit in a compact, sturdy case or cinch bag. The small size makes the system convenient for travel. Trainers and athletes can travel with their timing system and continue to train while on the road or at away meets.

Unlike photocell timing systems, Freelap can time multiple athletes simultaneously. For example, Freelap can time several sprinters performing fly-in 30 meter sprints on the inside lanes while timing mid-distance runners performing meter tempo runs in the outside lanes.

All of the components are mix and match; components can be purchased in kits or individually. Freelap is less than a third the cost of comparable photocell timing systems.

The system has been in use for over a year it all works but I expect to get all details online soon. Described here is a complete chip system intended for timing running races. With minor changes it can be modified to cope with cycling or triathlons or many other race types. Unlike other online chip timing guides, which tend to leave out a lot of the important details, this one includes everything needed, including software, to create a working chip timing system.

If you find some detail is missing, get in touch and I'll include it. Software is included to operate the chip reader allowing chips to be read, processed and converted into results for importing into whatever results program you have.

In its basic version, as shown below, the results will appear as a. As an example, here is the chip timer output file produced for this race. Time is formatted as MMSS so means 12m34s. Optionally, you can add a camera as a backup. What's described is the system designed for the North East Harrier League during This is a cross country league in the North East of England, run over 7 meetings during winter.

Each meeting has 10 races covering male and female, under 11 to senior, and each race consists of 30 to runners. A total of runners take part at each meeting. The races are handicapped so runners tend to finish more bunched than in a normal race of similar distance. The peak finish rate of the largest race is around 90 runners per minute and the system copes well with that.

You can see the typical results from a single meeting here. The system was introduced into the league as the main timing system in early to replace the usual manually recorded and timed results. It has worked very well since then removing the need for 16 officials and 3 race admin and getting results online within minutes of the race finishing, sometimes during the race.

This picture shows an entire 1 antenna chip reader in use at the finish line of a cross country race. There is a camera mounted on the tripod as backup and the chip reader, battery and tablet PC driving the chip reader are in the white box.

Click the image for a larger picture. For the cross country I set up 3 of these, one on the finish line as shown here, with a slightly larger antenna, and 2 in a short finish funnel. The one on the finish line catches The third reader is redundant and is purely for backup.

Main components To show how little you need to make a working chip timer, here is a view of a single antenna chip timer opened out from its case and labelled. The only addition you need is a tripod to mount the antenna on and an optional camera as backup, which would be mounted on the same tripod.

Click the image for a closer view. This reader has 4 antenna ports so can operate up to 4 antennae, but as explained later, 1 antenna will often do a better job. Some versions of the reader have 2 antenna ports and other readers have up to 8 antenna ports, but you won't need that many. The tablet shown will run for 6 hours from its own internal battery and the Lithium battery shown will run the chip reader for 10 hours so the system can be setup before the meeting and be left unattended for the meeting duration, which is about 4 hours for this particular cross country.

That's what will be described here. These systems were not designed for race timing, they are intended for logistics and are installed all over the world to track goods in and out of warehouses, trucks and ships so they are well established and not too expensive.Welcome, Guest.

A Guide to Building Your Own Race-Timing System

That, with some electrical tape to snug it up in a cleaned out spark plug threaded body. More tape on the indicator, just one or two raps, and it's pretty tight. I've seen an indicator with a one inch diameter face that looked ideal for in frame clearance. Just the weight of the gauge was enough to hold it against the tube but I added the tape just because. A tap and screw is more proper, but I ain't that way, so far. Every day above ground is a good one. The one I linked to earlier will fit a 2" diameter indicator on an RD, but it's tight.

Not Homemade, but I've used this little gem with great results. You don't even have to remove the tank. Can't seem to locate the eBay listing where I purchased it, but it's identical to the "Buzzetti Micrometer Timing Tool". So I'm sure if you hunt around you can find one cheaper.

Quote from: Redbird on May 12,PM. We have a Winner! Thanks I need to save that now so I don't forget it later. Question for you all with electronic ignitions.

First off, I haven't done much wrenching in many years, so please bear with me. Do all electronic ignitions available today I see several who say they have "Vape" ignitions use optical triggers?

For those with optical triggers, it's my understanding you use the devices above, with a dial indicator, to set timing.
