Turntable drive belt ..
Hi all,
My 14 yr old daughter has just bought herself a some 'records' (remember them) from a boot sale and of couse we don't have anything set-up to play them on (some Iron Maiden, AC/DC, Quo and ZZ Top btw g!) I dug out an old Hitachi turntable but the belt had turned into liquorice ??? I tried a couple of different elastic bands but all I could find was either too tight (short) or narrow (this deck needs summat about 24" (61cm) long (circumference), 3/16" (5mm) wide and about .5mm thick)? I'm not sure I want to shell out £5.99 + p&p or so for a replacement that may be only used for a few tracks so wondered if there were any DIY alternatives out there please? (And no animal intestine solutions thanks Mary!) All the best .. T i m |

Strip cut out of old bicycle inner tube; butt-jointed at an angle using a
"lap" of puncture repair patch on the outside? |

They join fails fairly quickly or, as the stiffness varies across the joint, it affects the speed/stabilty of the turntable and may even produce an audible thump. A slanted rather than a straight 90deg join might be better. Gives more area for the glue and a less violent transition in the belts flexabilty. -- Cheers Dave. pam is missing e-mail |

If you can find a belt that is bigger than you need, then it can be cut to size and super-glued. We used to do that years ago in a workshop, and it worked a treat. -- JJ |

I've just had the same problem, and a bugger of a job getting the right size belt. I also tried a rubber band for several weeks which worked well enough - you just have to find one the right length. Of course it will take a few seconds to come up to correct speed, but, if you're too tight to spend a fiver on a belt, it's prolly the best solution. If you try and use a piece of rubber and join it, you'll prolly hear the joint, but then ... for the above bands, does it really matter ? Why p&p, isn't there a hi-fi shop near you ? -- geoff |

Hi, This page has some avice on sizing: http://www.goodwins-online.co.uk/index.php?product=turntables&prod_name=Turntable%2 0Belts&list=2 and some info on Hitachi belts which may help he http://www.turntablebasics.com/belts/hitachi.html http://www.turntablebasics.com/beltmodels.html you must know someone near a Maplins shop that could put one in the post, their stock check facility can help out here too. cheers, Pete. |

Might improve the sound of the bands chosen. Its crystal pickups and broken needles that are the problems. Ceramics are more popular than xtal, but anything that looks 50s or earlier is better avoided if you want to keep the records long term. BTW dirty records can be cleaned with water and washing liquid, but it takes repeated wiping along the grooves to dislodge the deep crud. It would be an education for her to hear just how totally sh1te those grams sound, but would no doubt put her right off records. 8 tracks next, or wire recorders? 78s are a lot more flexible, so to speak, in that you can play them with a plastic cup, a thorn and a huge card horn. Sadly the almost non existence of anything worth listening to is a problem. But you can record your own on ali sheet blanks. You can always make your own pickup and feed it thru the hifi. I had good results (ok, delete the 'good') with earpieces, copper wire and assorted needles. So, it's off to "Elastic bands R us" tomorrow to see what I can find if you must make your own belt, use flat knicker elastic and sew the ends together with thread. You'll want to use pliers to force the needle through, it grips like a grippy thing. If the elastic is wo weak you cant butt sew it, make the overlap lump curved to avoid a thump as it crosses the motor spindle. Avoid cotton covered elastic if poss, it can work, but not well. If you keep the belt tension low you wont notice any thump, even with a bad join. Thats assuming its an ali platter, not a 5g plastic one, which create their own noise and amplify it as a sort of ongoing perennial winge about being made of plastic. Those can at least be tamed a bit with a thick rubber mat, or lots of plasticine underneath. Tension needed is minimal, it has to turn a tt on a central bearing and deal with the friction off a massive 2g of stylus. You can explain that wow and flutter is a good 1000x what it is on computerised systems, and with one of those strobe speed cards watch the lines go backwards and forwards as the speed goes up and down each revolution. And watch the pickup geometry as it progressively twists relative to the grooves. And explain why it howls when you turn the volume up, and where all the snap crackle and pop comes from. And if her IQ is in single figures, why no-one uses them any more. Yes you can make top quality decks, but not at sensible prices. NT |

The question is does the information coded on CD's outperform the information pressed on LP's? I've got identical albums on both CD and Vinyl which not all the time sound better on CD. Blame the recording companies for that one.... --- Adrian |

And in any case, a £50 quid CD player these days out outperforms a £1000 turntable. A CD player cannot cope with vinyl. Anyway, a digitally encoded signal can by definitition, never be as good as a pure analogue signal. No matter what the sampling rate, you can never reproduce the original accurately. -- AJL Electronics (G6FGO) Ltd : Satellite and TV aerial systems http://www.classicmicrocars.co.uk : http://www.ajlelectronics.co.uk |

Well you have touched on part of the 'goal' here .. and that's her education. We have 'talked' to her about stuff from a babe, and have played / demonstrated with stuff as well. I had her soldering at 5 years old and angle grinding / pillar drilling and MIG welding at 8. She also raced 12th scale cars and was winning ballroom dancing awards. I believe exposing her to all this stuff, old or futuristic is all part of what helps round her as a person. Some of her mates are more intelligent but come across as naive re worldly things in comparison? sounds like great parenting, too many think cotton wool and naivety is good for kids. Angle grinding at 8 though? Sounds scary. 78s are a lot more flexible, so to speak, in that you can The couple across the road have some ... maybe we can 'play' over there .. ;-) The very early ones were recorded on one side only, and had etchings of angels etc on the other side. You can always make your own pickup and feed it thru the hifi. I had good results (ok, delete the 'good') with earpieces, copper wire and assorted needles. Sounds like fun .. the the first sounds from your first Xtal set .. ;-) Yes, though technically the first sounds from my first crystal set were total silence. And the 2nd 3rd and 4th sets. I even have instructions somewhere from the 30s on how to make an answerphone using a pair of 78 decks. It used ali discs. And watch the pickup geometry as it progressively twists relative to the grooves. Yep and that any compensation has to work with those effects? There is partial precompensation, though its not perfect, but I dont know how one would compensate at the playing end. Linear tracking maybe. And explain why it howls when you turn the volume up, I even 'resolved' that one for my nephew recently on the CD system they were about to throw away ... I lifted it up off the same shelf as the speakers ... funny isnt it. Kids now dont even know what a record is half the time. and where all the snap crackle and pop comes from. Breakfast? apply breakfast directly to record... I think her IQ is reasonable (she's been offered a place at one of those "Gifted and Talented Childeren" orgs but "I don't want to play chess with geeks thanks" was her reply g) and is genuinley entertained by the stuff her and her old dad play with (mostly) ;-) thats great. Maybe they offer something other than chess? We were talking this morning about the new Hitchhikers film and she said she didn't want to see it as it looked from the clips like it didn't follow the image of the key characters like Marvin and Zaphod from the book and TV shows very well. I said "well they aren't trying to .. they are trying to follow the spirit of it whilst putting a more modern slant on it ..?" She replied "like it needs more slant .. any more slant and it would be horizontial!" (well it made me chuckle anyway) ;-) Heh. I liked the old hitchhikers film, but was always disappointed by the 2 headed Zaphod. I somehow hoped they'd figure out how to make his 2 heads a bit more convincing, but sadly no such surgery was ever forthcoming. NT |

Agreed, but you can drive it with a rubber band quite happily (FSVO "quite happy"), as I found while waiting for the right belt to arrive exactly the downside with stationery bands is the rubber perishes relatively quickly. Also some get lumpy or wonky when stretched, and they tend to be weaker (the proper belts arent very stretchy). But if its only for short use theyre usually fine. NT |

Ok, howabout you buy it for me and then you can have the deck for the 9.99+ years after we have finished experimenting with it? ;-) *If* I have need to order something from Maplin and can tack a belt onto the order or if I actually go past a HiFi shop that has one for less than a fiver I might just buy one. In the mean time the deck is back in the loft where it has spent the last 10+ years ... ;-( All the best .. T i m p.s. I could easily find 10 things to spend 'just' 5 quid on .. |

Hi Tim
Thought I'd replied earlier, but it doesn't seem to have got through... A couple of things used for motor-platter linkage on 'high end d-i-y' turntables a - fishing line, tied with a reef knot - dental floss, tied similarly I guess Seems bizzare, I know, but these are supposed to sound _better_ than a belt. I'd imagine how well this works depends on the diameter and shape of your motor pulley amongst other things. Might be worth a try...

I think the elasticity of a belt is supposed to reduce the flutter but equally if the linkage between motor and platter were more rigid(dental floss) the platter's mass should (could?) moderate the motor to some degree? I'd imagine how well this works depends on the diameter and shape of your motor pulley amongst other things. Might be worth a try... As you say .. I sorta have tried, in the form of a fairly thin elastic band and as John confirms later the drive motor output in this case is shaped like a barrel to ensure the belt self centres. I think I have seen your solution in action where the drive pully is 'V' shaped though and then the thin round / square line might work ok .. ;-) All the best and thanks for the second post ;-) T i m |
