Drop down gate
Drop down gate fold card
I’m making a drop-down section of track across a doorway out of plywood and hinges. I’m curious as to how those of you who have done it effectively line up track at each end. DO YOU Put A JOINTER IN PLACE BY SLIPPING IT IN PLACE? Use it as a 3-6″ removable piece, like the modilar guys do at train shows? Is it possible to design it in such a way that no jooners are required? Any help with the construction of this device will be greatly appreciated.
On that hand, the hinge or hinges should keep track accurately enough (for HO). My section is raise UP, and I used a small pointed piece of wood that fits into a slot on the “bridge’s” underside. It’s very well supported by the weight. A suitable holding system, such as barrel locks or trunk latches, is needed if you hinge down. There are no joiners on either end. Make certain that both sides of the door have solid benchwork. Any movement will cause the track/s to become misaligned.
In the previous posts, there was a lot of helpful advice.
In addition to what everyone else has said, I’ve noticed that the track on the end that swings up gets bumped and dinged quite a bit over time, causing the molded spikes in the track to loosen and the rails to start sliding out of gauge or come completely off the links.
To repair this, I solder the rail to the PC board and cover the last couple of connections on both ends with a small piece of printed circuit board. If you don’t cut a gap in the top of the PC board before turning it on, you’ll end up with a nasty short. On both of my bridges, this approach has kept the rails in place for over 5 years.

There are a few pictures and a brief explanation of how Gary Hoover installed a drop gate to access part of his new N&W layout in the Model Railroad Planning 2015 article on Gary Hoover’s new N&W layout. It made me think that, because I have to put a gate across the layout room’s access door, this form of access could work well on my layout. I started with some 3/4″ plywood for the roadbed and bought some hinges and other supplies. Has anybody got any ideas for construction, ensuring the track stays in alignment, and so on before I get too far along? Any ideas or tips will be greatly appreciated.
I’m not sure where I read it, but I recall reading about using drawer slides on one side and a narrow lip on the other. You can then raise the side with the slides and lower the other. I believe I was in an issue of MR a few years back. It’s stable and self-aligning. Of course, I belong to the third school of thinking, which claims that lift outs and duckunders should only be used when absolutely necessary.
It’s made of masonite, and the first coat of paint was applied with a small roller and a foam pad. After I finish the scale and scenery, I’ll fine-tune it. I just went with a generic blue up high and a white or light gray down low for the first coat, rolling and dabbing them together a little where they met. I’ll either add some picture backdrops down low or try to paint in the right infrastructure photos once I’ve figured out the foreground. I like to put up the rough backdrop before the benchwork is finished so that I don’t have to reach too far to mount and rough paint it. Here’s a shot from a little farther to the left, as it reaches the end of the room’s turnback curve. The shops in the first picture aren’t framed in this one, but they do go on the old kitchen base cabinet… DaveB is a member of our culture.

For displaying the cells under any acquired parameter, the primary graphical display has two drop-down menus (one for each axis) (FITC, APC, PE, Cy5, FL-2, etc). To change the axis scaling, a transform button sits next to each axis drop-down menu. Click here for more detail on axis transformation and scaling.
Options, Active Gate, and Statistics are three expandable menus at the bottom of the graph window. You may adjust the form of graphical display (density plots, contour plots, histograms, and so on), the colour, shading, and action of gates, and add a number of statistics using these menus.
Double-click on any population node in the workspace’s sample list to open a new Graph Window. Your cells will appear as events on an X and Y axis (as part of a bivariate plot), allowing you to distinguish and gate different populations. When you double-click on a node in your workspace, a graph window appears, with the forward scatter-area (FSC-A) and side scatter-area (SSC-A) plotted on the X and Y axes, respectively. This helps you to easily filter out debris (dead cells, for example) and focus on the cell populations you want to study.
