Align and park: Car Parking Tool

So I needed to find a way to help park my wifes car into the garage in the perfect spot every time so I could still work on my tool bench when needed. I didn’t want a ball on a string in the middle of the shop for when the car is outside and I am trying to cut down sheets of plywood. So I came up with this, I call it the Align and Park tool. Basically, its two top layer floating lines and one back layer stationary line, when you are in the perfect spot you mount them aligned at eye level (front car) on the side wall. Then when you are pulling into the garage the lines are not aligned until you get into the perfect alignment (spot). It is hard to show how it works in photos so I made a full video and example of how it works down below too.



Best way to explain in a photo:

Hmm, clever use of parallax. I suppose your head position matters, is it sensitive enough that you have to do something like lean your head on the headrest to be sure it’s in the right place, or is there enough wiggle room that it doesn’t matter too much in practice?


There’s a little wiggle room since the lines are engraved a little thicker. I just recommend mounting it eye level where you normally have your head position when driving. Obviously if you want it the same Everytime then just mounting with your head back against the headrest would be best.


In Naval aviation terms, “call the ball” Nicely done.


What a great practical design!


A very practical design many will need. I ended up putting one of those laser lights in my garage and I am always challenged at pulling up too far. This would work just as well!


Ooo that is a great design!

Items dangling from your rear view mirror fatigue a region of your brain that would otherwise detect a ball or a kid running out into the street.


NEat idea!


I LOVE this! Very innovative and smart.

That’s frickin’ brilliant!


Excellent work! Very Ingenuous!

Useless Trivia: We used the same technique with two lights for beach landings. The front light was a meter above the ground and the rear light was two meters behind the front light and two meters above the ground. If the two lights appeared vertically aligned from the ocean point of view, the boat operators (coxswain) knew they were coming in along the approach path.


For me this sure would be useless trivia…I can’t remember the last time that I had to make a beach landing which was probably never ago. However…this was fascinating to me…I’m glad you shared it. :grinning:


Thank you, thank you, I’m here till Thursday! Tip your waiters! :slight_smile:


Airplane pilots use a similar system called VASI to determine if they’re on the proper glide slope to land on the runway vs coming up short or over flying the landing and potentially run out of runway.

There are (usually) 2 bars of lights separated from each other so that when on the proper glide path (generally a 3 degree slope) the lights line up correctly. The top of the light is white and the bottom is red.

If all the pilot sees is red, then he’s coming in too low and will not clear the threshold. AKA, controlled flight into terrain.

If he sees all white then he’s coming in too steeply and will also likely punch the ground except at least he’ll have made the runway :slightly_smiling_face:

If he sees white in front and red in the back he’s on the line, will clear the fence and land on the runway where if he flares correctly he will just glide to a touchdown.


The only way I made it as a pilot was with mnemonics.
White on white, high as a Kite, red on red, you are dead.


:smiley: If it weren’t for the mnemonics a lot of us would be walking.

My local field has a displaced threshold and the runway runs straight into Mt Trashmore - not good to come in badly.


Nice, Much more artistic and high tech than my grandpa’s method of hanging a ping pong ball on a string precisely measured to touch the bottom center of the windshield when properly parked.

I’ve just been going for higher tech, less artistic, more lazy: with a lot of recent cars having ultrasonic parking sensors, I just stop when the dash says I’m 30 inches from running into my Glowforge workbench. :sweat_smile:
