Can someone shed some light on this subject as to what works? I can't ride a bicycle so I never used 1.

I have a older gps unit but I don't know how to mount it in the T for a speedometer.Can't keep em on the windshield of a modern,so I don't want to chase it all over the floor board of my T

I think not ' if you look down the pics there is a sending unit that mounts to the fork and a piece that mounts to the spoke of the wheel I don't know how to mount this on your car and get a correct reading. I think Steve has experience with this ,he will chime in soon. Cheers Colin

That wireless type bike speedo won’t work as the sender and receiver are too far apart on a T. Works only from distance of fork to handlebar on a bike.

I use the wire type bike speedo, but you have to splice a longer length put the gauge at the steering wheel. Pickup part of magnet mounted to hub, with pickup sender placed on a bracket you design and make to hold the precise distance needed. Not too difficult.

You can start here: http://dauntlessgeezer.com/DG105.html Steve Jelf has used a bike speedometer for a long time. You can also look up bike speedometer on the MTFCA and see the posts Steve has made there. It seems the weak point in the system is the wire connecting the pick up portion to the read out portion.

The wireless bike speedometer sounds very interesting.

Good Luck,
Terry

I have had bad luck with the durability of bicycle speedometers, even on my bicycles, so I would echo Steve's comments on their suitability for a Model T.

Have used this wired type for 5 years now, works well and accurate tested against iPhone GPS speedo app.

Handlebar mount fits just fine to cylinder horn button case. Large numerals good for my old eyes!

Dan, you must drive on tamer roads than I do.

I think it may work on the Model T. At that price it is not so expensive that you couldn’t write it off and chalk it up to experience if it doesn’t work. You can attach the magnet to a spoke and attach the sending unit to the tie bar arm with a few spacers underneath to get it close enough to the magnet to pickup the signal. Keep us posted.

Haven’t had any wire trouble as the extension to the pickup is heavy dual twisted and mounted to allow full swivel of spindle. Run in rain, sand roads and hard gravel can’t seem to upset the readout.

Do use a marker to write the ‘calculated’ input for tire size on the outside of the display, when battery dies it looses that measure so just type in the preserved numbers off the unit.

Tried it. I used magnet that is used for a security system. They a meant to attach under a window sash and close circuit until the sash is raised and therefore opening the circuit and setting the alarm. These magnets a very strong and very small so attaching to the wheel spoke was easy. The speedo worked sometimes but not very accurate. I believe the mag interfered and caused the reading to be unreliable. Gave up and use GPS when needed.

Some bike speedos are upset by the Model T ignition system. I've found the Cat Eye brand to be good in several cars so far. Accuracy with mine is spot on when checked with a GPS. I used JB Weld to secure a magnet to the hub.

Well that is plenty of info to work with. I like the rear wheel mounted idea.
Thanks for the help. And Randell,I had no idea a outfit could be bought for a modern to shine the speed up on the windsheild.THe link you posted,had me browsing for a hour.And checking ebay,where i buy since I don't a account on amazon,and 20 bucks or less will put the speed and such right up where you can see it while driving!. Neat0

Just another option for speedometer...

I use a bicycle GPS speedometer with great success. It's about 1" x 1.5" and weighs nothing. It's rechargeable from a computer USB port. You can attach it anywhere but mine attaches to a velcro dot in the middle of my lower windshield. I paid about $60.

Why not use a speedometer that was designed for your car? I have original period Stewart speedometers in all of my cars, and they work.

I am wanting something cheap.Those original speedos look nice,no complaints other than exspense..Since I am trying to get this thing road legal I don't want to ride without a speedo as the local Barnies love to write tickets!

I have had one on my T for about 8 years never had a problem whether it was cheap at the time maybe 20-25 bucks Works great I think I only replaced the battery in it Once I'm not sure of the brand I will go out and check tomorrow take some pictures of the pick up bracket and Magnet install. Pretty simple to make and attach Have the display mounted right on the steering column pretty small and unobtrusive. Did have to extend the wire not a problem and mounted on front driver side wheel. Will post some pictures tomorrow.

1 thing that might affect how I can mount sensers is I am running wire wheels on the T's I want to put speedos on.The pickup is finished and working towards road legal,the speedster,still a work in progress.

I use an App on my phone. All my old cars are a bit off so I check myself just to make sure I'm ok. The App was free.

With spoke wheels you might go with this.
You can tell by the frequency of the noise how fast you are going.

Here are a few pictures of my Install hope it may help someone

Thank you for taking the pics.And like you said,it might help others.
Right now I would rather get a modern cheapo bike speedo and put the real money in the vehicals mechanicals.

I do like the idea of an electric speedo on the T as an option. Once I attached my phone to the windshield and used an app. It worked fine. But for the past several years I’ve been using the original set up with the Stewart 160 head and the chain drive. It’s great when it works ... which is most of the time. As they say it’s as good as it’s weakest link. Wish good, smooth new links were available.

that is modern cheapo speedo probly 20 or 30 bucks

Here's my light shedding for ya.... You said you already have an older GPS and need something cheap. The reason you don't use it in your T being simply a mounting issue.

I would suggest considering the many benefits of the GPS besides just a speedo. Depending on your model there are several good options for mounting a GPS. I mounted mine on the fire wall just above the coil box on my '12. It works perfect for speed and can also get me back home when the directions fly out the car on tours! I did have to install a small battery for 12V power.

What Gene said. Garmin has several mounting options to choose from. I use a ball mount with plastic hook between windshields on Touring. And a sticky ball mount to dash on coupe.

I will check into that,I bought a Garmen for 10 bucks at a yard sale never took out of the box till i got it.It would be good for that,but my experiance was with the rubber suction cups and they fail miserably.
When I bought a new up to date 1 for my modern I got a sand bag looking thing for it to be on,it just sits on the dash.
Ball mount,magnetic? I think my neighbor has 1 of those,I will see how it works and may just go that route for right now.Just 1 area in the small town I might get over the 15 mph speed limit,don't need a ticket!

How about something like a universal GPS/phone mount with the suction cup removed and a disk magnet glued to the bottom (piece of felt or something on the bottom to prevent marring the dash). Stick it on the dash. There are many variations of the GPS/phone mount that would accommodate a magnet (round or rectangular).

Mack,

With Steve Jelf's inspiration I mounted the sensor in the back as per this discussion and easy instructions: http://www.mtfca.com/discus/messages/70 ... 1498439804

It has worked for a few years now without problems.

Had the speedometer die on an old motorcycle and found an early model hand held GPS unit at a garage sale for $15.00. Made a mount to attach it to the handlebars and hard wired it for power and it worked great for a speedometer. With the new style GPS units fabbing a mount would be easy and you get the added bonus of being able to find your way as well.

Okdoky, I will make or get a mount for the gps. less money! And more functions.
