I needed to create electrical gaps for the reverse loop and electronic reverser testing. I used a fine Zona saw to cut through both rails on two sections of R20 at the half-way point, creating a pretty fine gap in the rails. I had to hold the track up to the light to ensure the gaps went all the way through the web, they do.
On my first attempt to cut the rails, I cut about 1-1/4" from the end. Bad idea. The small plastic rail spike heads holding the rails to the roadbed did not have enough strength, and one of the short-section rails popped-out. It went back in, but does not seem strong enough. I set this section aside.
Consequently, I decided to strengthen my gap-ed track sections with some superglue. I purchased this LocTite superglue, which dries clear. It is actually more liquid than I would have liked, so my gluing is messier than I would have liked. Hopefully this will be less noticable when dry. I put glue on both sides of the rails, across the gap, and at three ties on either side of the gap. I used a disposable plastic fork to try to work the liquid glue into the small rail joint. We shall see if this is sufficient. I will file down any glued tie points that contact the flangs.
