Making a very HEAVY DUTY Lazy Susan Turntable from scrap
HTML-код
- Опубликовано: 16 май 2019
- I make a heavy duty turntable for video production and display. This oversized lazy susan uses heavy rollers and should be good for almost 500 lbs. Thus was just a simple diy project I came up with in a few hours. I plan to add a center pivot that will allow me to motorize it in the future.

What a great idea i love it!!
It works pretty well, needs a center pivot though.
That is a great idea!
Thanks, it is working out pretty well but it needs a center pivot which I will get to eventually.
Cool. Be handy for reassembly and tear downs, painting, welding, time lapse etc. You could obviously do it other ways too, like stack another brake drum (might be another sized one on top of the one with the rollers (in place of the pulley) so that the tall part of each brake drum fits into the other. That way the top one kind of registers into the bottom one (while it's face rides on the bearings below it- you could even face cut the top drum in the lathe, and machine a little race groove into it's surface for the bearings to run in), and you'd have that large flat surface on top to mount your final "table top" to. You'd also have recessed through holes in the center of each disc where you could "loosely" tie the two drums together with a little axle and small round bearings, or even with a few hard wood rounds, a bolt (like a capital I shape), and plenty of grease that the wood can slide on as it rotates in the recesses. And if you machine a groove in the side of the top drums "tall part" ... then you can use it as a pulley.
All good ideas. I went through several iterations, including trying to do a rotor inside a rotor but did not have the right combination. I wanted to just use stuff out of my scrap pile. It was really just a proof of concept, and the lip on the pulley was a lucky happenstance. It makes the whole thing very short which is also good.
I think I have the center pivot worked out, in my head at least. The thing that I am not sure about yet is the motor. I have several but none have a gear reduction that is heavy duty enough. The ball rollers work but it will still take quite a bit of force to move it. i would like to use a v belt if possible, just to make it as quiet as possible but I also have many sprockets so a chain drive is possible if the belt does not work.
@@theeddies I feel ya. I like when things happen to fit. I love making stuff out of junk for that reason. Maybe use a garage door opener motor/sprocket/chain assembly if you can find a trashed one. I just happened to find one earlier today myself. We went out "junking" (which is our term for garbage picking lol) as weekend sport -to find whatever might be useful, but along the way we also ran into a few garage sales. At the first one I was going to buy an old pump oiler can, but I passed on it (I could go back I guess), but someone in the family was a locksmith at one time, and his box of stuff was there... There was this kind of trifold "pouch" thing (like radius gauges come in, but bigger) that was all master keys for like every old brand of American cars (Likely 60's to 80's), but they were super thin like feeler gauges. It was cool, but things were all kind of overpriced, so I just left it. BUT we hit another garage sale a few minutes later.. electric guitar and a little Marshall practice amp both for $10! On the junk voyage I found a nice SMALL shop vac that I cleaned up and have hanging over my lathe for easy clean up.
@@theeddies I just thought about it... you must have tried or at least thought about using wheel bearings, right? I wish I had some more of those things.
@@johnstrange6799I thought about tapered bearings because I worried about the side loading. But that was before I came upon the rollers, they take that load now. The standard double bearings would probably work, It is not like it will be spinning at 500 rpm, lol. I still have the hub from the Lexus and a cheapo bearing for those is around $18. Which is not a lot more than I paid for the rollers. It would definitely be more stout than the thrust washer and 6030 bearing setup that was the leading thought in my head. It would take a pretty big redesign and would have to be taller but worth a think. Thanks!
Garage door opener!! That is a good idea, I think my dad has one hanging in his garage, he only uses it once or twice a day😀. No, seriously I think he has one that he keeps putting on Craigslist, maybe I can see if he will make a donation.
THANK YOU. How many google results for make big lazy susan from scratch which just showed attaching pre-bought hardware (as if that is making one from scratch!) did I have to scroll through to get to you? Very cool! People who can think are great!
Thanks! it is pretty basic but it does work well enough for my uses. And except for the very cheap bearings is otherwise scrap pieces.
Did you ever motorized it? That’s the parts I’m most interrelated in
No, I am still waiting to happen across a motor with enough power to turn the weight but also slow enough. I am sure there are many possibilities but it has not been a priority enough to spend a bunch of money on it. I frankly was never happy with the rollers either. They really do not move smoothly enough. As a concept it worked. I did put a full size motorcycle engine on it and revolve it by hand for a video segment. You can see that in the opening of the following video - ruclips.net/video/JeKHDVuo8KY/видео.html&ab_channel=the_eddies
But so far it has been a bit of a fail honestly.
It is principally a thrust bearing
yes, essentially
