DIY Turntable

- My first DIY turntable with a 33 lbs. platter. It uses a Rega 303 tonearm and Ortofon 2m red cartridge.
**No sound before1:30************************
It was just me stating that the platter and S.S spindle are the only items sent to a machine shop. Hub has two bronze bushings and a thrust bearing in the base of the hub. The motor base housing contains a Hurst 3905-001 motor. From all the comments I have received I have since replaced the main pulley to a non-ferrous material. There were two issues one being over heating of the synchronous motor and the other issue was the obvious wobble from the pulley not being machined true. The replacement pulley is made from Delrin material. You can see an example of the replacement pulley in my second build • DIY Turntable # 2/ Aud... .

I think it was a great idea to draw and plan out the exact measurements and dimensions for everything to make sure it all worked
Cool! I too have a Rega setup that I've been thinking about Frankensteining. Well done!
Great work mate! Really nice.....
Steve Murrell Thanks!, I appreciate the complement!
Absolutely amazing! I would love to get the measurements and materials you used for the platter and spindle etc. I've been looking around for a while for the perfect slab to make a plinth.
Credits where credits earned. Good job brother!
Granted I have built two turntables to date I don’t think I’m ready to share what I think is unfinished work in the form of plans. I see so many things that I think could be improved or that I like to change. I was just excited that they worked and they weren’t so bad to ones eyes, well my wife thought they looked good.
Awesome work, beautiful turntable!
Very sofisticated ,as it requres tooling .I did in the past one myself out of car parts .For the platter y used car wheel drums my axle was an engine valve and its guide mounted in a aluminum block ..The drum was sent to be lathe rectified .something that is done routinely ..so inexpensive ..
Wow this Is truly an awesome build with great insights, thanks a lot!!! I wanted to add that I’ve had a major issue with motor noise with a high and turntable that I purchased a while ago, and ended up putting the motor out of the main turntable assembly myself as well. That is really the only full-proof way to get any noise out of a system: the motor simply cannot be attached to the same body where the arm is. I have set it up in a very temporary (and cosmetically unappealing) form as I am still fighting to get a proper chrome or silver casing that looks good to drop the motor into, as well as trying find a proper vendor that has good turntable belts (or any kind of belts that will serve the purpose) since the original belt of the turntable can’t be used anymore (the new length is obviously different, much longer than the original). Still no clue where or how I can find or build a proper metal cylindrical case to put the motor into and that matches the rest of the turntable, and still find thing to find a good place to buy belts. Again, thanks for sharing your video :)
Thank You for your comments. My motor case is just a water pipe caped with aluminum. Fortunately for me it cleaned up well.Point being I’m sure there is a simple and practical solution right in front of you. You could always start anew,? You already have an external motor. After posting the video I made some changes to the table which I noted in the description. One is that it uses fishing line as a belt. One spool offers a life time supply! Oh and it’s very cost effective. The most important part is it effect on the sound. It doesn’t transmit any noise that I can notice. The rubber belt I had also stretched which effected the speed. They might be ok on a 12 pound platter but not a 33 pound one. Good luck on your project and I hope you get the sound you want from your system.
You are an artist! Your whole set-up looks amazing!!! Congrats on all😊
That is beyond awesome! Congratulations man on your genius!
Thank You! Some times passion will lift you beyond monetary limitations to create something comparable to what is commercially available.
Wow.....very very sweet👍 That baby needs an upgrade over the Ortofon Red though🤔 Very nice work .....
The 2m red has been replaced long ago. I currently use a Nagaoka MP-150 and a Parks Puffin Phono amp. I know it’s not pure analog but it works for me. I may at some time try and source a tube unit but until then this will do.

That motor pulley wobbles a little, doesn't it?
Nicely done!
Thanks!
The so called simple turntable......Can be approached from all sorts of different angles...Some go down the avenue of super light platter with index wheel feedback to keep motor at correct speed.Others like yourself go down the flywheel approach with very subtle coupling to motor through thin belt.........Yours looks more impressive.😊
It is simple but at nearly 30 kilo’s or 66 pounds I wouldn’t call it light.
You need a thicker platter to prevent wow and rumble.
Dear friend, your turntable is beautiful. I'm building my turntable right now. Now I ran into a problem with the engine. All DC motors I tested are noisy and I have a problem with speed stabilization. Can you tell what engine you used and how you solved the problem with stabilizing the rotation.
My project is a compromise when it comes to speed fluctuations. At worst I am at .5 and at my best .001 from 33.33. In either case I couldn't hear the variation. Mybe I'm too old now. If you have read the motor i used is from the same spec that VPI uses so if they can charge 6k and up it's ok for me.
I one other note, I did try using the rubber belts that VPI uses ( not oem) and found that they start driving quicker but can add to the wow measurements.
That’s a great TT build. I have a question for you. I’m building a table using a old Empire motor and platter . It’s all self contained setup. I need to know where on the P broad do I install the tonearm? This is the only part I’m unsure of. Please help. Lol
You do have really good jokes♥️
Fine job ! Have you had the machine shop check the runout of the drive pulley as the motor turns ? In the video I think I can see some wobble .
Thanks Joseph for the complement. The pulley in the video has since been replaced. I don’t own a lathe, so removing material to gain zero runout was not possible. Having the machine shop turn the platter and shaft proved to be very costly to my budget. Having an additional item turned wasn’t an option at the time. I also discovered that the hurst motor in combination with the steel pulley interferes with the magnetic field. This was preventing startups without a push. So the pulley I currently use is made of Delrin plastic. Just note this was a DIY project and I was well aware of the runout issue. The speed accuracy is 33.29 -.12 and wow/flutter is .16. There are other flaws but I can live with them for now. I have plans to address them later. I’m currently building a second turntable and I will address any of my previous tolerance issues.
I saw a turntable a bit like that on RUclips but the platter was like twice as thick. Price was $150.000.
Now all you have to do is make a nice uni-pivot arm and get rid of that Rega.
Mate, you are an absolute audiophile! Do you have the worry of platter weight killing the ball bearing?
Being that this was a DIY project I tried to source as many parts from what I already had. The trust bearing has some history. The bearing was originally apart of one of many since crashed remote controlled helicopters. The model was a Miniature Aircraft Tempest. This trust bearing supported the centrifugal force of one rotor blade. Someone with more math skills than me calculated that with a 700mm blade spinning at 1700rpm would generate a load of about 700 pounds! I think 33 will be no problem. The bearing is sitting in a well of synthetic motor to reduce wear and also reduce bearing noise. Thank you for referring to me as an Audiophile your the first! The project was born out of the desire to have what I could not afford. Its not hard to see where I got my inspiration for the design. With that said 4k and more for turntable..... I think I could have out sourced every single part and still would have come under 4k in US dollars.
Nice build. Somehow, am sure this table can much more - red is to little for such a machine.
If your referring to the 2m red cartridge being too little it has been replaced. I'm currently using a Nagaoka MP-150 cartridge with a Parks Puffin phono amp.
Please tell me that the music was you bro!!!!!🩸💵💰🔝
I listen to everything !
Great project! The pulley is visibly wobbly during spinning. Have you encountered any speed issue?
If you read through the comments you’ll see your not the first to point out the flaw in my amateur build. I have since replaced the pulley with one that is non-ferrous. I later found that it was causing the motor to over heat. With a Delrin pulley in place there was no longer any magnetic field interaction and the motor now runs within nominal operating temperatures.If look in the video description notes there is a link to my second build . You can see an example of what the pulley looks like. Thank You.
That is awesome and quite an undertaking. I didn't even think DIY turntables could even be done. How much did it cost, how many hours do you have in it and how did you make sure the speed id nuts on?
I spent about 3 months playing with drawings and another 2 months slowly putting it together. The biggest problem was finding a motor that would allow the correct speed. I saw some ad's where some people were selling their motors from a vpi deck. I got the model number and sourced three different Hurst synchronous motors to play with. All the motors were fixed at 300 rpm. The first pulley was steel and removing material to get to the correct speed was very hard but successful. I have since replace the pulley with one made from Delrin. I confirmed and fine tuned the speed with an app on my phone "RPM PRO". The motor is spot on as it was checked with another app called strobe light. There are only two ways to adjust the speed, change the pulley diameter and for very small adjustments stretching the belt. I'm hesitant to put a number on construction cost as the wife might see this. Let just say it was just under 3x's the cost of the going rate for the tonearm. The order of highest cost first, platter/machining, tonearm, wood and all other aluminum bits.
Hello, can you give us more infos about the motor and trasmission please? thank you
There isn’t a transmission just a motor and pulley. The model number is given in the video description. My intention was not to make how to but maybe in the future.
Awesome
Thank You
I saw the video and was very interesting in getting one but you built one and that is awesome all day in my book just wanted to ask how much would it cost to build one like yours
@@nathanielduran970 . The only parts that I didn't work on were the platter and the spindle shaft aside from mfg. items. So the question is really what can you do on your own will dictate the cost of any build you do. It took two months of my time to complete each the two turntables. It isn't a quick process. I will say this that my single greatest expenditure was machining.
👌👌👍👍
Thank You!
And the TMaxx didn’t try to start
Still waiting ………
@@furyanflyer Heard several unfortunate incidences death in the family multiplied by two Christmas Eve and Christmas day
Wow, great...What a strap? From what ?
Aleksandar Aleksic , Thanks You. I’m not sure what your questions are but if you clarify them I would gladly answer them.
@@furyanflyer Tell me more about belt, please.
Aleksandar Aleksic , I used 6 pound monofilament fishing line.
Can u make me one of these without the tonearm?
Corey Henkel, Yes, I could make you one without an arm. But honestly you could by a VPI Scout. I’m using solid 2” zebra wood vs VPI’s High density particleboard. I’m sure VPI could make a dozen plinths for the same cost. I have not considered making them for sale. If you really want one and are willing to wait a month , I could do that. You can contact me at sr20detbarrett@gmail.com.
A nice hobby, but either a SLP1200 or properly plynth'ed SP10 would produce superior sound reproduction with better isolation. 90 g or 180 g vinyl will absorb ambient vibrations, so dampening it with a 33lbs platter slab is redundant. Unless it's a floating magnetic bearing, there'll always be RPM fluctuation on this belt drive. The absolute best vinyl player is a laser ELP unit, vinyl will never degrade from a stylus carving it over time ! And zero rumble hum resonance !
Your absolutely right:).This was an a exercise to see what I could create. It was not to best any other commercial product. I used the same motor that is used in VPI's 6k turntable. I don't use rubber belts because they can transmit vibration from the motor, hence the use of a very thin monofilament line. The mass of the platter doesn't just address vibrations, it also helps minimize speed fluctuations. I checked the speed and wow/flutter with "RPM PRO", My turntable is bit slow at 33.29 which is -0.12% and the wow/flutter is 0.16%. I'm currently laying out plans to incorporate a magnetic bearing on my third build. I do hope it will meet your approval. Thank You for your input :)
@@furyanflyer 33.29 / -0.12% and wow/flutter 0.16% is terrible because the material cost/ build time versus the playback quality is about the same quality standard ratio as a $99 turntable from Best Buy.
FICKFEHLER I had hoped this was a constructive critique It sadly seems your only out to troll.. I look forward to seeing anything you’ve built with your own hands if you can. Peace Out!
@@furyanflyer No need for a DIY TT. home has a Delphi MKIII + SME345. Office has a Gyrodec. Ortofon BLK on both. Cheers
😂😂😂
gay song
I try my best to stay happy.
Hmmm... I finally followed Ann's advice and took Woodprix. It's great for beginners and has some advanced stuff too.
