Here Goes Nothing (warp in the over related)

Well, it's flatter now, burt have to notch the deck up to 4 grams to get it to play without bouncing the needle out of the grooves....
But it DOES play through now! Nothing to play in the clubs but more useful than the talisman it was!
 
How warped was it originally? Unplayable, I assume?
Yeah, I was not able to get it to track at all. Traded a cracked 45 (Help Murder Police) that played through okay for this warped one. There was probably a 1/4" or so from top of warp to bottom of it.
 
I started by buying two 3/8" thick pieces of glass (13" x 13"). Then I made a cardboard cutout out of a (flat and smooth) stevie wonder record cover that somebody had used as packing material in a package that they had sent me. The concept of the cardboard cutout was to counteract the thickness of the labels on either side so that the pressure would be equal on the edges. I then preheated the over to 200 degrees until the walls were good and warm. I turned the over off and put the record in (in it's cardboard and between the two pieces of glass) - Left it in the oven overnight and in the morning I inspected the progress and found that there was not enough. With the record still out of the oven, I re-heated the oven to 200 degrees and started again. After about 4 hours I took it out and placed the record/cardboard/glass sandwich on a table and piled several heavy books on top and let that sit for a few more hours.
Seemed to do the trick!
 
Having already spent the money for the glass, I myself am sort of committed to the DIY method... But to any out there inspired to work some dewarping, I think that Frantic has good advice!
 
Thanks for all the info. Just ordered the Vinyl Flat. Also went for the pouch, as I'm not confident in the accuracy of my oven's temperature.
The sale does end tonight.
 
Yeah, the consistent temperature control seems like a REALLY handy part of the process. My efforts with my gas oven make for a lot of trial and error.
May it serve you well!
 
A collector friend uses vinylflat, and has become quite adept at flattening 45s. He has a copy of the War Lords on Thor that looked near mint, but it had a bad "jump" warp, and would not track at all. After using the vinylflat machine the record plays perfectly and traces of a warp are gone.
 
i once tried to flatten a 45 in the oven, stuffed between two pieces of glass, held together by bar clamps. i think it worked. don't know for sure, because i forgot the record in the oven and everything that remained of it was a big hunk of black slimy goo.:crap:
