I am having the familiar issue of the locking tab for Tray 2.

 

I'm able to remove the PIU do a patch job using JB Weld 2 part epoxy which did hold up but for only four tray insertions and removals.

 

However, the piece broke the weld and I've seen some videos where you do a plastic weld with a soldering gun.

 

Does anyone know the type of black plastic used on the 5SI PIU?

I was able to use the Stick Putty with great success.  I drilled  small holes, coated the edges with the putty, secured the broken piece in place with my screw and washer setup and then press more putty in the drilled holes.

 

I removed the screw and washer setup this morning and the broken piece is now SECURELY sealed in position.

 

Thanks for much for that recommendation!

On some plastics in order for this to work, you need to drill tiny holes in the plastic and ensure that you force the JB weld into the holes when applying. This creates teeth that will lock it in place. I normally use the two part welding epoxy that comes in a stick that you knead and then apply.

I should point out that I violated the first rule of using epoxy and that's being mechanically sound before bonding.  The piece I tried to bond was anchored in two spots but not the third and it was the third spot that failed.  Now to remove the piece again and peel off the epoxy.

 

I did see videos about making small holes AFTER my first attempt to bond.

 

I've never seen epoxy in a stick.  Back to the store for me.

 

What's your opinion on plastic welding with a soldering iron and a zip tie?  I've seen a plethora of YouTube videos on people successfully using this method.

I have never tried that method myself. I typically use products like this

I did buy the Plastic Stick with 700psi strength.   However, I also bought Gorilla Plastic epoxy at 3700psi strength. 

 

I'll drill tiny holes along the crack and try the putty stick first because it would be more malleable for the holes.

 

The piece I'm fixing is the little ledge looking part (see attached picture) of the PIU does have some stresses once the tray is inserted.  I used 4-40 screws with washers to hold the part in place while I drill and epoxy.  I did have to remove the end assembly to gain access to place the screws.

 

Thanks for recommending the putty stick.20231228_083420.jpgtray tab.jpg
