The arm may not be preforming as good as possible for the construction prinsible, but not bad.. :)
Frank, if you see this, some advice could be well come.. ;)

very cool. l bet it sounds good. I mean excellent, not average.
whenever I see nice 'tables, my heart aches for a rega9 I sold. |

That´s much better ! ! !
:bigeyes:
wow looks great. It must be very heavy. |
|

Looks great !!
How does it sound?
How about some details: motor and controller type, source of bearing, constriction details....
Can't wait till i get to finish mine- Great job

Jep, quite heavy.. the TT and the stone platform are both a little over 15 kilos. Like in the Scheu original there is lead inside the round collar. Only buying lead pebbles would have been quite expensive so I melt down some car/truck tire weights for it. It looked kind of ugly though by its self so I pored some coffee to the sides. :D
The stone platform is actually a gravestone (not a used one though ;) ) Wasn't quite first class so I got it cheap. Also the pillars around the motor are from the same stone worker. They are cutouts of completed gravestones.
The platter, bearing and motor are from Scheu Analog / the arm is of coarse a Schröder copy.

IZHAKKATZ, sounds quite good.. :cool:
In many respects it beats my CDP, a 2k euro player... the TT, cart and also phone pre are still running in - so we'll see.
Also, since I have very little experiance with proper TT:s I'll probably buy a Scheu classic tonearm for some kind of reference. Also I'm thinking of building the Poul Ladegaard's Air Bearing Tangential Tonearm to see if it's a good one. :)

Another picture too.. |

Hi,
nice work with the tt :). About the tonearm... is it a clone, or just you used Scheu for inspiration? I mean did you tried to reproduce their magnet bearing? If yes, I'm intersted how it sound, 'cause I'm planing one :) |

That must sound dead ;)
Looks as a very nice turntable, congrats! :up: |

Hello jugi63,
Nice job on the arm, but I'd need a little more than just one pic to give you some advice on how to improve upon it. Any problems you have/had with it? Did you use maple for the base cylinder and armwand?
Cheers,
Frank
@SunRa: It's not a Scheu designed arm... ;-) |

Frank,
you are absolutely right - no SCHEU at all;)

Hi Frank! Thanks for answering..
Thanks also for the inspiration! :)
I'm amazed of the sound even now. So clear and musical! The sound of instruments and especially the resonance of string instruments are so much more authentic!
With the arm everything is basicaly pretty clear but the function its self isn't quite as good (You are right - no easy task). The tonearm tends to wobble from side to side if lowered to where I think if should be. The gap between the magnets is now some 3 mm. Any lower and it flips from side to side. Although the arm sounds suprisingly good even now, I suppose the gap should be about 1mm?
So would this be a defect of the hole in the magnet not being exactly in the center? The magnet hole is spark drilled at a local firm, so it should be fairly well centered. Or also maybe the antiskating disturbes the ballance - a too strong line? 23kg pull, 0.35mm thick, I think it was.. (not home right now).
The wood of the arm wand is alder, the other wooden parts are beech. After taking the picture I added a small weight along the underside of the wand to rise the effective mass a little to better suite the Shelter 501 II cart. Also I'm thinking of soaking the wand in epoxy to further resist resonancies. Worth it?
If I can't get the magnets close enough to each other, I'll probably save up to buy a Scheu Cantus or Classic - only I'm also thinking that maybe the version I already have may sound better than the Classic mkII at least?
Also I apreciate the fact that this is Your patent and profesion, so would you rather discuss (asuming you will discuss) this in private?
Thanks!

Sorry I meant schroeder... it looks pretty similar to the last schroeder, the one reviewed by 6moons |

bravissimo.

Hello Jugi,
Just send me a private mail after tuesday and I'll tell you what makes the arm flip either side when closing the gap..., but it has nothing to do with the antiskating - and the thread diameter is in the ballpark :-).
Soaking the armwand in epoxy isn't necessarily going to make it less resonant, it'll just change the res.-distribution.
Cheers,
Frank |

| Very nice looking table. I am curious about the clamp. Where di you source the record clamp or did you make that? |

Consider 'skinning' the arm wand, like an egg. This will work wonders. Long story.
If you have multiple wands, that is. To test each type out, or at least, that way you can reverse the situation if you don't like it.
Try the artist's brand "tri-art" brand 'topcoat', a watered down, ultra thin layer. (A highly damping but ultra fast hard and flexable acrylic-urethane mix-same base resin as BMW's vehicle topcoat, I believe.)
The best way to do it, is to thin the topcoat with distilled water, about 4:1-5:1, stir thoroughly.
Tape off the parts that need be clean for screwing or mating purposes (:D), and then dip thoroughly...and shake off the excess. Sounds rude, but this is likely a path to getting the resonance out of the armwand. The dipping and then the shaking off will create a layer that is even in thickness. Or, dip and then wash off (use a lint free cloth, go fast, this stuff gets sticky very fast). Let dry, maybe do another. The slight soaking into the wood from a few dippings, will do the trick. Ultra thins lead to the highest level of musical pleasure. :p
Same treatment for the rest of the wood.
It will take up to 6 months to fully cure the topcoat. Some say two years later, it is still hardening. Viagra for wood that needs permanent hardening. It has even been used to coat entire log cabins (soaking of all logs-massive wood!-before the erection stage) |

Hi Fomob,
The clamp is made of aluminium, just a wheight - no threads. I bought it from Scheu Analog. http://www.scheu-analog.de/de/index.htm

Hi KBK, Thanks for the tip! I'd like to try it but I don't seem to find Tri-art anywhere here in Finland. Is it just Tri-art topcoat or are there some other similer products?

Look at what's available in Holland. I think it's available there. I'll check.
edit..too much information. Technical information, that is. ;)
Ok. closest so far, is ATLANTIS artist supplies in the UK.
It's the only one in the market, it is unique. The mix is a cross stressed or cross linked compound, ie, tiny bit of one type of material encapsulated by the resin of the other. Literally a 'water based acrylic urethane' mix. In your house, on a turntable, about a 100 year life span.
So, it's rock hard..and completely flexable. So, it ends up being very, very 'fast'. And your arm will be completely UV resistant. :p
About a week ago, Steve put some on some paintings. It is still shrinking. The paintings are nearly bulletproof now, and the frames are bending so much, they are going to explode from the pressure, as the resin shrinks. They change note, and the pitch of the drum get's higher and tighter every day. It's crazy. |

Hi Jugi,
nice tt!
I'm interested in the motor you used. I found the Scheu Analog's site but the price list is on German only. Is the motor you ordered this one: | quote: | | Kollektorloser Gleichstrommotor, EUR85,- |
How much was the total cost for motor + shipping to Finland?
Best regards,
Pete |

Anyone here using their counterweight/VTA system which I see from the german price list is only from €65!

Yes, thats it. It comes with the potentiometers and a good ON-OFF-ON switch (they are already wired in also). So you have both 33 & 45 speeds and they can be easly fine tuned. So all you need to do is attach the power supply. A very basic wall mounted DC power supply works ok - although there are differencies in those too.
Have a look at this months Finnish Hifi magazies - there's an artical about mine.. ;)
Orders from Scheu a cheap. For the motor probably under 10 euros.

Jugi, thank you for your reply!
Did you consider any other motors before ordering this one? I think I'll read the article in a library;)

Well, not really. I have quite a big trust for Scheu's stuff. People with some very expensive equitment seem to like Scheu TT's - and motors.
Maxon was a motor manufature I looked at a bit, but rekoned that the Scheu motor is at least as good. Can't say since I've no experience with Maxon, but as I happens there came a info paper with the Scheu motor where he (Mr. Thomas Scheu has passed away already) compares is motor to the "famous" Maxon and concludes his is better and more simple to run evenly.
The soundscapehifi.com/eurolab.htm -site has some nice info about Scheu (and others) and some it is trancelated in Finnish at: http://www.musiikin.com/scheu-page.htm
