Warped records...

Hi,
I picked up some cool tunes at my local ZIA's, I usually check the records but was in a hurry tonight. One of the records is warped real bad, but it plays on the AR-XA ?? Any way to flatten it again? It's a good record, "Jean Luc Ponte" A Taste for Passion...otherwise Mint condition.

Thanks,
John.:music:

As long as it's not lifting the stylus from the groove, I just play them.

When the LP is "warp down" (least surface area in contact with the platter) it can help to have a record clamp. :smoke:
 
Hi,
Wow, cook the LP? What kind of vegetables goes with that?

I don't know Someone else told me to put it under a horizontal pile of other records for a week? Maybe I will just leave out in the AZ sun for a few mins...

Thanks,
John.
 
Many years ago I succeded by putting the LP between two wide glass plates, securing the corners with clamps, and putting the set under the sun for a few days. It's sort of the same idea, but much cheaper. A good idea would be to perform a test with a reject LP to see how it goes.

All the best

Looks like something that could be made with about $30 worth of parts from a hardware store. :thmbsp:

Parts cost for high-end equipment is usually 10% of retail, so probably about $250.

If you could make one for $300 retail, you'd have a big market.

But I suspect there's a lot of trick computer circuits involved to make sure each LP cooks perfectly. The R&D costs would be high, both in time and ruined LPs.

Fedallah's link to this method of heating in the oven between plates of glass is the best method I know of.

In the past I have also simply put the LP on a large clean cookie sheet in the oven. Nothing on top, just the LP, leaving it in until the warp relaxed and settled down. That works, too.

Or not. Ususally you have nothing to lose, the LP is already messed up, so you can't do any worse.

Simply placing it under a weight without heating will do no good. The vinyl will just spring back to it's warped condition.

So, how do LP's get warped in the first place?

Leaving them on the seat of your car out in the hot sun is one way. What, you would never do that? Go look at your kids' car and tell me there aren't CD's laying around. Or on the floor in their room. Kids did the same thing with LP's in the '60's. No, not playing them in the car, but going to friends' houses with the latest Beatles or Herman's Hermits LP was common.

Another way was to leave an LP lying on top of a hot tube type TV or amplifier. That'll do it.

Or near a window with the sun shining in on it.

And sometimes they just warped for no good reason. It happens, so get over it.

If you want to fix it it's going to take some heat. You have nothing to lose.

Hi,

I think I will use the HOT AZ sun (110 degrees yesterday in shade) on this one for a short time to see if it flattens out.:scratch2:

Thanks for all the ideas.:thmbsp:

It is fairly simple to make something with off the shelf parts - look at the McMaster-Carr catalog for blanket heaters, thermocouples, & a temperature controller. One 12" square silicon blanket heater runs $62, temp controller $135, & figure $20 for thermocouples & connectors. Then a couple 1/4" tempered glass plates from your local glass shop & you're at or above $300.


If anyone tries the oven method I would recommend a convection oven to avoid hot spots.

Hi,
It's like the record cleaners, they run a few hundred and up! I wash my dirty lp's in the sink and vacuum them dry. I wonder if you could use the dish washer for them?

One of us should make this and patent it...
