Tach Tape Replacement Suggestions Please

Question, if you have the old tape, why not reglue it to the flywheel?  3M makes some good spray adhesive.  What about it causes you to think it wouldn't work if it was still on the wheel?

Check the stickies on the top of the DCS control forum. GRJ put a scan of the tack tape in the documents section

Print it on some sticker paper

It is now black and yellow stripes because the old adhesive has bled through the tape.

I print them on full page shipping labels and cut them out.  They've always worked fine for me.

What John stated would be the hot set up.   

I right clicked the tach tape attachment and it printed a full sheet. They look too large. What did I do wrong?

Make sure you're printing it at actual size.  I just downloaded and printed it, it came out exactly the same size as the stock MTH tach tape sheet that comes in the upgrade kits.  Top is what I just printed from the documentation thread, bottom is the gummed label set from an upgrade kit.  The slight apparent difference is because it was a bit closer to the camera, I should have cut it off and laid it flat.  I can assure you, it comes out exactly the right size.

A 30mm sticker (flywheel diameter to answer the OP's question) is just over 94 mm long.   Circumference or length of sticker = flywheel diameter x pi (3.14). If measuring with a ruler, note the "invisible" white stripe on the left side to give a total of 24 each black and white.

Thank you everyone; great responses. Hopefully, my intuition was right and all I have to do is replace the tach tape. If not, then I will be back for more advise.

OK. Thanks John. Once I downloaded and then printed to actual size, it worked out.

great tip!

One other tip - I had printed these out before as ‘actual size’ and found out my printer actually printed at a bit larger than 100%.  So you may have to test out your printer and if I recall, I printed at 97% and they came out  perfect.  This is likely printer specific, but just a heads up.

It turns out that all the sensor needs is the transition black to white or vice versa.

I changed the gearbox on an MTH Hudson, and knew the chuff would be off.  I merely adjusted the number of black stripes with paint and a shaky paint brush.  Worked fine.  No need for perfect spacing.  I get a chuff for every 90 degrees of driver rotation.

Not rocket science - the stripes do not need to be uniform; just the correct number.
