Reshaping plastic parts

[mbielman]

I have an HP67 on the bench and one issue is that the battery door is warped presumably from an overheated battery pack. It still closes "OK" but the battery pack is a bit loose.

Found a printed door from the UK but shipping is 3x the cost of the door!

Wondering if it's possible to reshape the warped one somehow. Found a site that uses hot water to do this (ABS) but skeptical and don't want to make things worse. https://thefrugalprofessor.wordpress.com...tic-parts/

Has anyone tried this or have other suggestions? Would prefer a replacement at a reasonable cost.

Thanks!

Hi,
i had a similar problem with a HP-97 door. I used a heat gun and bent the door into the correct shape.

Hot water may work either, but you have to overbend the door a bit. I think you can control the heatgun better.

I don't have an actual heat gun. Would a 1500W hair drier be hot enough??? ;-)

It would probably be hot enough and much safer, i.e. not so hot as to melt the plastic. Practice on something you don't care about first
