This is fantastic. I’m in the process of purchasing a house that is on a busy street with a narrow driveway. I’m wanting to build something like this into the garage, that I plan on building.
Thank you John, a fun build for sure! Funny thing was i wasn't even sure if it would work when i finished. The car is 5500 lbs and the motors are only rated at 400 lb load. there is three of them but I was still well-shy of the vehicle weight!
@@capetide 🔴 What Is Islam? 🔴 Islam is not just another religion. 🔵 It is the same message preached by Moses, Jesus and Abraham. 🔴 Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God. 🔵 It reminds us that since God created us, no one should be worshipped except God alone. 🔴 It also teaches that God is nothing like a human being or like anything that we can imagine. 🌍 The concept of God is summarized in the Quran as: 📖 { “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4) 📚 🔴 Becoming a Muslim is not turning your back to Jesus. 🔵 Rather it’s going back to the original teachings of Jesus and obeying him.
@@p__jay Known by many names. It's essentially conveyor roller track. This kind looks like Nestaflex (brand) gravity conveyor. Search for "roller conveyor 90 degree". You'll either need x4 individual 90 degree corners, or a long enough flexible one, to make a complete circle. It's around $600 per corner brand new at uline dot com, or you can find it on ebay or at a commercial liquidation/industrial supply type store for a little less.
Thanks John! Total cost was about $1600 or about 14% of what a commercial unit would cost. Fortunately I work in a business where aluminum beams and gear motors are plentiful!
Well done and great job. is the motor driving the turntable through a ring gear just like on a flywheel of an engine? I am interested in designing something similar for a narrow basement garage.
Hey Joe, yes exactly! I used a linear gear and then gently bent it around the perimeter of the turntable. However since it is almost impossible to cut a perfect circle (turntable) and seeing how the gear drive is only 3/8 inch deep, better to go with drive- wheels for the rotation! I was surprised how easily it turned a 5000 lb, car! You only need 3 or four motors. Total cost was less than $2000!
Well it's already built, so hard to give a step by step now. But I'll try: I used 'skate wheel conveyors' to build the circle. I measured the wheel base to make sure the conveyors diameter would allow the front and rear wheels to rest on equally on it when parked. I bolted tge conveyor tracks together and leveled them using bricks and stone. I added stone to the inside of tge circle for drainage and to lock the circle in place. Next came tge decking (2 layers) the bottom layer being 3/4 plywood and the upper layer was plastic decking. If I did it over, I'd make both layers plywood (painted on both sides). By tge way, I kept testing for rotation as I went along, making sure it spun freely at every step. Finally:how to spin it? This can be done a number of ways, tge best I think is a motor driving a pinch-wheel on the outside circumference of tge turntable, several of them! Hope this helps.
All in, about $2200. I have seen them commercially sold for around $10,000. The skate wheel conveyors I found on ebay for $800 with shipping, materials (stone, 5/8 plywood, decking, paint, screws, concrete) were another $800 truck hub for center support $100. 3 gear motors $350 Marine 12 volt battery $125. I wired in a transmitter to turn the platform on and off and the gear-rack bent around the circumference of the deck for the motors to drive the platform, make up the rest of the $2200. If i were to do it over,, and I may, I'd use a friction drive, instead of gear-drive motors. I've actually thought of just bolting rubber skateboard wheels to the top of the gears on the motors, and lowering them. Remove the rack gear from the platform and see how that works!
Kinda motor you use? Microwave turn table motor? Lol.. id say one of those little old gas pop n fart motors would work pretty good. Be cool to go all binford on it and hook a 1000cc R1 motor to it and see how long it takes you to pass out in the drivers seat... lol
You didn't need that many rollers. Now when there's load on it, it flattens the part where it's being rested on and literally all of the rollers have a weird jerkiness to them when you rotate the turntable.
Doesn’t more rollers distribute the weight more evenly? I estimate roughly 2,000 rollers and a Toyota FJ Cruiser is around 4,300 pounds plus the wood that’s only like 2.25 pounds on each roller. The rollers deforming from that small of a load would be like your skateboards wheels deforming if you left it out over night.
@@EvySpaghetti Also, this is one of the biggest waste of materials for solving this particular problem. That's why commercial solutions go with worm drives.
That was a video for your ego. Sorry that wasn't helpful for us who's wife's after watching you video want a turn table for their car now. P.s Good job though. 😉👍
I was wondering where you were going with that Jason, sure maybe a little for my ego but mostly to show others it can be done and done cost effectively. My friends and i share our contraptions, not for an ego boost but for fun!
