New 'Vinyl Flat' flattener?

ok everyone here seems to have experimented with lps,all good and well. but i`m concerned with 45s. i haven`t had any success with the groovy pouch at all. i had a stevie wonder i wish with a pinch warp in for several hours,no change. girl watcher ABC with a severe edge warp for several hours,no change. and an aretha franklin on checker with a few pinch warps on for 11.5 hours,no change. anybody want to comment on this? i`m wondering if i should use the oven. i did a 10 min on 170 with a pinch warp motown record with no effect either. also put 2 minor warped 45s in the groovy pouch for 3-4 hours with no change.

well i don`t have a thermometer so i`m assuming if it is not accurate it is probably higher. yes i spoke to vinyl flat. he said at 170 to be careful; to start at 10 and probably go for no more thasn 20 min. i put in aretha franklin on checker with a pinch warps for over 20 min and no affect at all. here`s my rub. everytime you see anybody here on the net talk about flattening records with any method,it always seems to be albums. and i can see that as albums are not raised in the center so the weight is on the whole record with direct contact and not just hovering over the middle of the record. the other thing is; vinyl flat`s sheet that tells you the heating and cooling times for the different labels and for usin in the oven gives the gram weight of the particular label. well,these gram weights are all for lps obviously no 45 would weigh 95 grams and up. even if a 45 was 2 0zs that would only be 56 grams. so if they experimented on 45s; where are the results for it?? i will try ther oven with some milder warps for however long. if i keep getting no difference,this item will be returned. has anyone here personally flattened out any 45s with more than a slight warp via any method? if in the oven,what was the exact particulars and results?
