advice on removing bumpy edge warp

[chas_kit]

I bought this warped copy of Richard Pash. The edge has four small bumps, two are inconsequential, but the other two need to be flattened. Any advice on this? I don't want to press the whole record if there's another method, as the rest of it plays fine.

That looks to be unfixable. Heat damage warps are pretty much a done deal, probably not worth the time & effort to find the correct amount of heat and pressure required to lessen severity of the warp-age.

I had a rare soul 45 that looked very similar, the stylus would not track until half-way thru the song. I sent it to a guy to try and see if some time spent inside the "flattener" would at least allow for playback. The warp did not flatten enough and ruined the 45 completely.

It almost plays the way it is, so it doesn't need much. I'm not going to put it in a flattener. My idea is to flatten those bumps a little with a not-very-hot iron, with non-stick parchment paper next to the vinyl.

DO NOT USE AN IRON.

I've done it in my gas oven on a real low temp the lowest you can get. Sandwiched between 2 silicon bowl lids and 2 cake tins with some weight on top. It evenly disperses the heat, an iron will warm the edge and the edge won't do what you want, It gets worse and will end up looking like it already looks - but extra warpy (in fact this looks like someone already tried ironing it)

The "warm oven sandwich" actually worked but this was an experiment on a badly warped record probably worse than that but it wasn't a record as good as that!!!

Look at the "vinyl unwarper stats" and you'll get an idea of weight and temperature http://vinylflat.com/vinylflatinstructions.html

here too he uses glass http://blog.vinylmeplease.com/guide-to-flattening-warped-vinyl-records/

Good Luck, but I never told you to do it.

Thanks, I will do much experimentation on worthless records before attempting anything with the Pash. If I don't think I can do it, I'll send it out.

There was a clean copy on ebay for pretty cheap, still going begging for a couple weeks. If you or anyone else was looking (and it hasn't sold yet)

You can't de-heat a heat warp. The material has expanded, the grooves are stretched out. Unfortunately.

I've seen many warps like the one above that had no heat damage to the grooves. About 5 years ago I had a frequent buyer on ebay who would buy badly warped rare records from me for good prices. He promised to tell me his secret on fixing them but never did. I sold him $500-$1000 records a number of times times for around $75-$100 and he left me positive feedback each time because he repaired them. The one demand he had was while the record could be super warped, there could be no heat damage to the grooves. So there are guys our there that can fix these, it's just that they won't give up the process.
