Kidney shimming gone wrong - HELP [emoji30]

[imperialbrewer[TK]]

I had just finished up my kidney shimming and was test-fitting my armor when the ABS pasted seam split:

 

 

Here’s how the supporting shim was constructed:

 

Inside:

 

Outside:

 

And then ABS pasted:

 

...followed by the whole sanding, polishing routine and repeated until the surface was flush and clean.

 

Any suggestions? Tips? Should I have heated and bend/curve the piece that I shimmed on? Other things I should have done?

From the looks your inside support is too narrow. You need a wide coverstrip to absorb the flex. E6000 as wide a pc. You can fit and redo seam. 

This is just a speedbump. You got this!

Agreed.  That is not much support given the stress the joint takes.  I would consider a piece that gives at least 2" of support to each side of the joint, preferably 3 to 4 inches.

 

Nice work on filling the gap with slurry.  Sorry its tearing.

Let me also add, these types of lessons are hard learned, but we all make them.  Do not get discouraged by this. You will come out of this an experience an armor builder and better for it.

Thanks everyone. Will be tough to fix that cover strip — used zap a gap so removing it won’t be fun. But thanks for the encouragement!

You could add spacers each side and then cover all that with a single part?

So here’s where I’m at — I have a similar issue like before where the darkness of the seam seems to come through a bit. If you’ve had this issue, what have you done to fix or conceal the seam? Or is this OK and good enough to fulfill Centrion requirements as far as the shim is concerned?
