Have a white demo of BUSTER AND EDDIE, had it for a while and got it off ebay. The guy selling it to be fair said it had a nasty edge warp BUT it DID play thro with a lot of weight on his record players tone arm. Hardly any bids obviously, left well alone too risky ? I put a speculative bid of $75 and actually won it. When it arrived, sure enough it had a bad edge warp and for the first ten or so revolutions it would jump wherever at the start grooves i placed the arm. I had to heavily load the tone arm to get playing success. So I thought oh well I didnt pay a lot for it, it was worth a punt, then I just stuck it in my record box and forgot about it. Over time however, and having been asked several times to play a request for BUSTER AND EDDIE it started to get to me as I would'nt interfere with peoples Dj equipment to weight up the arm on a deck so I could risk playing said record. So I had heard of a crude method to FLATTEN the edge warp so I thought 'he who dares' just give ita go..... Taking a domestic clothes iron set at the lowest heat I cut a foot square area out of a newspaper(most of the sheets thickness) and folded the paper in half to a thickness of about 2-3mm. Letting the iron (switched off) cool for about a couple of minutes I placed the record inside the folded newspaper (2-3mm thick) either side of the record vinyl area effected by the bad warp. Laying the record with paper either side on a hard flat surface like a kitchen work top I the applied the nearly toucheable iron plate to the top layer of paper covering the record.Then with a gentle ironing motion locally over the warp for a minute or two transfering, not to hot a heat thro' the newspaper, I was able to gradually flatten the offending warp. Doing this did leave a kind of light sheen on the vinyl, obviously apply heat to B SIDE of record but after a couple of goes I was able to play the record successfully without having to add any weight to the arm. RESULT !!!! I now have a BUSTER AND EDDIE to play out at gigs, bring on the requests Incidentally I dont recommend trying this with a STYRENE record, I just think vinyl is a bit more workable with a heat process. If you have any records in the same state maybe a cheapie, then give it a try, remember be patient better to only put a 'warm' heat into the method and keep checking your record and gradually trying a little more heat and a little longer with the ironing pressure. It worked for me
