How To Diy Turntable Repair

• #1

Guys,
Does anyone know how to make a turntable belt?
I'g trying to figure out what materials I can utilize and how to actually make information technology (searches on the cyberspace find nothing other than "replacing" belts).

To give you some info: I am using a Pro-ject Genie motor and an acrylic platter fabricated for the genie (acrylteller).
Even so, the distance between motor and platter are currently quite a flake more than on the genie, so I cannot use the genie's belt.

How about a elastic thread ? I and all my friends here are using elastic thread. yous can go it from wear supply attempt the thinest i, beginning turn by hand beginning before switch on but your motor has to be speed adjusted, this idea is from SPJ

Nosotros don't like o-rings?

The manufactured ones (as opposed to the DIY ones made from superglued string) are more often than not well formed and seamless.

They come up in all shapes, sizes and flavors too.

This is what I was planing to do for my table project, simply if this is a bad idea, I'd similar to know now!

PS since in that location are also foursquare-department O-rings, this might exist a better solution- these blazon seem to be what are used on some tables...

Endeavour using fishing line. Do not employ the Spider Wire type, that has almost no stretch. Just good old cheap stretchy line-fishing line works great. Use a lite line weight similar 4 or 6 lb and double loop it. The smaller line diameter means smaller knots.

Silk thread ever seemed a favorite, my test Tt is running on a unmarried strand of cotton sewing thread.

I'm using upholstery thread (from Walmart) with a square knot. Maybe not perfect, but information technology is working for me. If yous are looking for more of a belt, you lot can try magnetic tape. I've used 1/4" R2R, but I don't see why y'all couldn't use cassette or VCR tapes if those widths worked ameliorate. I was using packing tape to splice. Regular "scotch" mode tape didn't want to concur for more than a few days.

ok, so when non supergluing prophylactic-similar strings, how practise you connect the ends of a slice of, say, silk string? Just tie a knot?

• #8

I think that is what is washed.

However, I don't see why you couldn't also lap the ends and super glue those as well.. (except if you take a very pocket-sized drive caster which may take too small a radius for the potent cord area; although I suspect it would practice the same with a knot?)

I don't know. Haven't got that far yet!

(Notwithstanding leaning toward an O-band as no one says not to )

ok, so when non supergluing condom-like strings, how do you connect the ends of a piece of, say, silk string? Just tie a knot?

a thin rubberband thread with a knot is ok fifty-fifty you tin't see the knot besides. you can endeavor them all and detect out the deviation and make the final conclusion, there will be a lot of fun in doing that and will not cost likewise much coin

I utilize this tape from mcmaster.com. 75895A21

It's a very thin polyester tape. I cut the ends on a bias (so there is a more gradual transition to the double thickness part), overlap a few cm to create a belt. Then I glaze the remaining exposed adhesive with talc. I use the not-adhesive side against the turntable and motor spindle. It's kinda tricky to handle during construction, but once you brand a good belt, it tin can last for years.

I experimented a lot with culling fabric to make TT belts.
I tried magnetic record, dental floss, o-rings and and so on, but for me the all-time is surgical silk.
All stretchable materials, including rubber, tend to produce time delay that creates energy storage and sound degradation.
Equally such, using a non-stretchable fabric gives an incredible comeback in sound quality. It just seems to take another TT a lot more than expensive.
Besides, surgical silk does non wear, fifty-fifty after years of employ. Information technology lasts longer than the TT.
For joining the ends a foursquare knot is plenty, and doesn't affect rotation.

I experimented a lot with alternative material to make TT belts.
I tried magnetic tape, dental floss, o-rings and so on, but for me the best is surgical silk.
All stretchable materials, including prophylactic, tend to produce time filibuster that creates free energy storage and sound degradation.
As such, using a not-stretchable material gives an incredible improvement in sound quality. It just seems to have another TT a lot more expensive.
Also, surgical silk does not wear, fifty-fifty afterwards years of use. It lasts longer than the TT.
For joining the ends a foursquare knot is enough, and doesn't affect rotation.

attempt 1 more time with very very thin elastic thread, rubber belt is non sensitive plenty. also thick, the thickness should be same every bit sewing thread, in my case, the result is opposite elastic thread can hear more than alive than sewing thread or whatever other not-stretch stuff, those rubberband thread maybe y'all can find in garment and clothing textile supply store, key betoken is little force tin can come with a lot stretch use tension to suit slip

Thanks for your advice.
Former ago I tried a kind of dental floss that is thin and elastic. Bad results: I lost all the advantages I had with the normal not-rubberband unwaxed type. Tried also sewing thread simply results were far from what is obtained with surgical silk. I think that in my setup it is the all-time I tried until now.

When I was a bench tech long agone repairing anything that came into the store, we had a belt kit which consisted of various sizes of belt stock, a fixture with a razor blade, and some glue. You matched the size of the sometime chugalug, cut the right length, glued it together and you were ready to go.

I was looking for something similar tonight and came across this thread, but couldn't find the kit. Anyone else call back something like this?

Hi,
Try MCMelectronics in the Service Parts and Components. They have all kind of belts replacement.

My Dad'south shop (Foreigh auto repair) had a 'custom' O-ring kit which was essentially the same thing.

Get some cord stock, a razor and super mucilage and yous can make safety belts all day long!

If you lot get extra gum on the od, merely wipe it upward with Acetone once it dries.

I agree with Clack. The stretchy belts don't sound as tight and controlled. I utilise a belt made of automotive upholstery string with a foursquare knot. All-time belt I've institute so far.

• #18

To brand that knot the Japanese showed me to loop through twice and the knot then has the string come up out and is very flat on the one side. No speed crash-land effect. Lots of testing got me to push and carpet thread in a nighttime gray color available at a sewing store. This is the largest diameter normal thread without going to something huge. The dark grey had the about friction by quite a chip. Yes different colors were tested and nighttime grayness was the winner.

I've tried them all and I've settled on simple cotton/nylon thread from the wife's sewing box. Works bully.

• #20

IMO it depends too on the motor caster you are using.
I've tried surgical silk simply the knot on my caster generates an axiomatic shock when running on the motor pulley. Best an old magnetic tape.
