HP tape drive novel repair

My thought (given there?s not a shortage of open space inside the chassis) was to put a car jack inside and jack it up thus pushing out the top. My concern there was that there would be an ?equal and opposite reaction?). Perhaps a 2x4 that goes side to side under the jack would alleviate this. But on freenode #classiccmp (where I hang out pretty much every night), PJustice and Sark both had similar ideas for an alternative approach that took advantage of the fact that the top of the chassis has a lot of vent holes on top. I implemented their approach and it worked very well so I thought I?d document it with pictures and post here. I should note that this approach only works because the angle iron I used was 14ga. Anything less would just bend itself.
