Case Tube Tool - Quest for one that works

[Waggy]

Hello, I'm after some help on getting a functional tool for removing and replacing case tubes, the friction fit type not the threaded type. I have previously owned two Chinese Ali Express tools, which worked, but in each case after using on a watch case with an angle the watch had to be manually held perpendicular and when this angle was not perfectly aligned the pusher pin inevitably received a slight side load and the tool body was damaged. Due to the fact that the hole which holds the pusher pin is so close to the end of the block and the material wall is so thin:

The result was that the hard pusher pin stretched and deformed the hole and the pusher pin was then slack and no longer perpendicular, and eventually the material split altogether. After I looked at the tool I realised that the block the hole was machined into was aluminum, this coupled with the extremely thin wall made this hole very weak and prone to the deformation and damage I had experienced. I looked to another reputable supplier (see below) who advertised their tool as "all steel" and I even contacted their customer support who confirmed that the block in question was made of steel. I was very disappointed yesterday when it arrived and found that it was in fact aluminum and not steel as promised. I could tell by the feel of the material (weight) and confirmed with a magnet which would not 'stick' and have since requested a return/refund.

Assuming the return/refund goes smoothly, I am still left with my original problem of not having a tube pusher tool - does anyone have any recommendation for a tool which will work and will also stand the test of time?
