Re: Custom CW Whisper, Custom Universe Smokescreen and Bondic Review
Bondic is great. I used it to repair the tail joint of my Trypticon ( http://www.cybertron.ca/boards/showthread.php?t=75052) and it's the closest thing to plastic welding without all the trouble. Thanks for the tip!
One thing I did notice in the instructions is to think of Bondic as welding as opposed to using glue when trying to join two pieces of plastic, which is usually the case when repairing Transformers. This implies that I actually need to carefully pick the type of welding joint to use ( https://en.wikipedia.org/wiki/Welding_joint) which I didn't have to do if I am using glue.
When I welded the ratchet joint in the Trypticon, I was essentially welding two cylinder ends together. That means I can only shine the UV light on one surface to cure the liquid plastic. Given it was the first time I was using Bondic, I didn't know if the UV light could penetrate through the entire thickness of the joint. As such, I sanded both surfaces to get a "single-V" joint to ensure that the UV light will penetrate to the inner surface of the cylinders to cure the liquid plastic.
If I was using Bondic to fix the CW Scrapper tab ( http://www.cybertron.ca/boards/showthread.php?t=74202), it's like welding a thick plate (the tab) to the surface of a cylinder (the bar where the tab broke off from). I would have had to cut a "double-V" joint to ensure liquid plastic (applied in layers) and the UV light can penetrate the joint because the contact surface between the broken tab and the bar is so large and deep.
So yes, it is important to consider the use of Bondic as welding as opposed to a gluing. |
