GRRR!!!!I just pounded out an explanation describing how my first and most thoughtful reply was lost to the either, and that comment was lost again! Ok. I better keep it short: Bike computer: good idea if the science works at high speeds and wheel spin. Forces are much greater than bicycle tires. Autometer had a calibrated column mounted speedo years ago. I explained it in detail, then my post was lost. Putting it out there in brevity 'cause I might crash any second. More time? Ok. AutoMeter's system was a standard gauge where you would log a known mile.press a button at the start, again at the end. A mag pickup on the driveshaft. I need to put my new computer together... this is getting annoying.

I use a bicycle computer for current and max speed plus distance traveled. It uses a magnet attached to a wheel with a stationary sensor to measure each revolution instead of GPS tracker. You could also setup a speed trap on the the fastest part of the track with two invisible beam sensors 30 feet apart into a timing system like a drag strip.

Looks like you nailed the grinder keyway hack however if you need precision you can use your lathe to cut keyways in a pinch… By chucking up an endmill and then running your cross slide as a fixture for your axle. I’ve had to do that once and it worked out well! Anyways, good job guys keep it up!

[@goodnough1]

@Isaac Davenport it's a sweet machine, but the brakes could potentially put way more strain on the chain than the engine would. So most likely, when it does fail, it will be at the worst time possible.

I think an awesome idea for your rally track is to make a zipline camera on that straight across the field. Run a long cable from a tree on each end, hang a gopro from a zipline and have someone waiting until the driver comes around the bend and send the camera and you'll get a really awesome cinematic swooping chase cam shot that will almost look like a chopper. I think they actually make zipline camera rigs if I'm not mistaken! Either way, you guys have amazing shots and great editing and stuff.

As already mentioned. I suggest using a bicycle computer/speedometer. You are able to enter in the tires circumference to get very accurate speed,and odometer readings.

There is an electronic bicycle speedometer that a friend uses on all of his motorcycles. Reliable up to well over 100 mph.

Looking through the comments I don't see mention of it, however you can buy little 10Hz GPS pucks meant for road-course tracks. These are bluetooth and will just connect to your phone.

I think it has an option to "build" the track layout too.
