| DT-400 Replacement Battery Covers - Brian Sheron |
| The other
day while I was running trains, I pulled the battery cover off of my
DT-400 throttle to flip the battery around. When I put it back on, I
apparently didn't get it aligned just right, and one of the "ears" that
hook the cover into the main throttle body broke off. I e-mailed Digitrax and asked if I could buy a replacement battery compartment cover for the DT-400. The response I got said that Digitrax doesn't sell them, but one of their dealers, a company called DD&B Systems in Ohio, sells them. I called the company, and I spoke with a very nice gentleman named Bob Chapman. He said he sells the covers for $7.50 each, which includes shipping. Address is DD&B Systems, 950 Raintree Court, Westerville, Ohio 43081-3134. Phone is 614-212-212 and e-mail is bobchap@columbus.rr.com. |
| Foam Rubber Work Surface - Brian Sheron |
![]() |
How often do we find ourselves working on a model with miniature (nay! minute) parts, such as tiny screws, nuts, springs, etc.? And how often does that small screw you just loosened up or are trying to start into a thread suddenly fall out of the engine or car onto the workbench, and then bounce somewhere such that you will never see it again (or at least until after you give up looking for it and drive to the hobby shop and buy a pack of screws even though you only needed one)? One way to reduce the probability of this happening is to work over a piece of packaging foam rubber (see figure). Many products, especially those that are fragile, come packaged with foam rubber packing. I’m talking about the packing that has hills and valleys in it, spaced about an inch or so apart (see figure 1). Working over a piece of foam like this has two advantages: one is that if you are working on a fragile or delicate model, the foam provides a soft cushion to set the model on, and 2.) when you do drop that small part, there is a high likelihood it will fall into one of the depressions in the foam and stay there. |
| Starting Small Screws - Brian Sheron |
| And speaking of small parts, how many times have you had to get that micro-sized screw started in a hole you could hardly see? Yes, they make special screwdrivers that are supposed to hold screws in the screwdriver blade so you can start the screw. However, I have found they don’t always work well, especially with very small screws, and small screws with Phillips head slots. A trick I often use is to dab the tip of the screwdriver into a tin of soldering paste I keep on my workbench. The soldering paste is just sticky enough to hold the small screw on the end of the screwdriver while you maneuver the screw into position and get it started, Once the screw is started, the screwdriver easily pulls out of the screw slot. For you auto mechanics, axle grease will work equally as well. |
| Finding Small Screws - Brian Sheron |

Despite your valiant attempts to hang on to that small screw, they sometimes drop and hit the floor. Have you ever knocked that box of wood screws you were using to build benchwork on the floor? Or, if you are like me, knocked over that container of small track spikes and sent them all over the floor? A small magnet on a telescoping handle (see figure) is a real timesaver when trying to pick up these small parts. I found mine at a tool sale at an auto show. However, they are sold in most auto supply stores, and I imagine some hobby shops would carry them too. They can also reach under those hard-to-get-at places that Murphy’s law says is where all dropped parts will end up. |
| Cheap Clamps - Brian Sheron |

If you work in an office, you will know that the spring-loaded paper clips (see figure) are a staple (no pun intended) of the paper-pusher. However, these paper clips also make good, small clamps for holding small pieces in place and under pressure while glue dries. Also, did you ever have to glue something and hold it in place or keep pressure on it that was in an interior location? Small welding clamps may be the solution (see figure 3). These can reach in and clamp your work in that hard to reach spot. The adjustment screw on the end of the handle allows the width of the jaw opening to be adjusted to fit the width of the work you want to clamp, and also the locking pressure on the work when the jaws are closed. I also found these at an auto show, but any place that sells welding supplies should carry them |

Harbor
Freight Tools has a rolling seat for
$29.99. It is about 15" off the
ground, rolls on 4 caster wheels, has a cushioned seat and a tray
under the seat to hold tools, screws, etc. and seems ideal for working
under the layout (wiring, installing switch machines, etc.). I
just bought one because I'm installing some under-the-table switch
machines, and got tired of getting up and down all the time. |
| Gluing Weights/Angle Plates - Brian Sheron |
![]() |
I have found numerous times that I need fairly heavy weights instead of clamps to hold some some model pieces together while the glue dries. Also, when you are gluing the walls on that building you are making, you want to make sure they are at a 90 degree angle with the base. One way is to buy professional modeler’s angle plates. However, these are fairly expensive (a 3” x 3” x 3” plate in the latest Micromark catalog is $27.15 ). I took a trip up to the local welding shop in our community and found 5 pieces of about 5” x 5” angle iron cut in about 3” lengths for which I paid a total of $10. I found a can of Rustoleum Spray in my garage, and soon had 5 good-looking pieces of metal that could be used for gluing weights or even angle plates (See figure). I also have an assortment of small pieces of metal bar stock I got at the welding shop that serve well as gluing weights. |
| Liquid Plastic Glue - Brian Sheron |

Gluing plastic model kits together usually involves using a liquid plastic solvent glue, such as Plastruct or Testors. This requires brushing the glue on with the applicator brush that is attached to the jar lid. For some applications, this method of application works fine. However, when you want to either cover a large area quickly or run a bead of glue down a seam or wall joint, I found that a syringe bottle sold in hobby stores works wonderfully. Running a thin bead of glue down a seam, where two walls join, a wall and a base, etc., puts the glue exactly where you want it. Capillary action draws the glue into the joint and results in a tight bond without excess glue. At the left is a picture of a typical syringe bottle. |
| Wax Paper Gluing Surface - Brian Sheron |
| Do you sometimes need to glue joints, such as butt joints or other joints which require holding them in place while the glue dries, and which glue is likely to ooze out onto the surface they are laying on? When the glue dries, you find you’ve glued the parts not only together, but also to the table! I keep a roll of wax paper in the drawer next to my work bench. Whenever I have to glue up something in which glue could ooze out and glue my work to the workbench, I rip off aa piece of wax paper and lay it on the workbench, then glue my work on top of the wax paper. Most glues will not stick to wax paper, so when the glued joint is dry, just pick up the work and peel off the wax paper. Any residual glue that is left on the work can be scraped off. |
| Drink Holders - Brian Sheron |

During an operating session, many of the “crew” will have a beverage with them. The last thing you want is for them to put it on the layout while they are busy switching a yard, or flipping turnouts to route their through freight. One bump and you may kiss goodbye to some scenery, a structure, or even short out the railroad. This holds true for me too, when I am working on the layout. While there are many commercial drink holders, those that are mounted to and stick out from the front of the layout can be a problem. People will walk into them or snag them when trying to pass a fellow operator in an aisle. To eliminate this problem, there are drink holders made for boaters that fold up out of the way when not in use. I purchased mine at a local West Marine dealer. They cost about $10 each, so they aren’t all that cheap. However, I find them well worth the investment. When an operator finishes up his chores in one area of the layout, and moves with his train to another area, he simply grabs his can or bottle and flips the drink holder closed . When it is closed it sticks out no more that about 1/2” from the front of the layout and poses no hazard to traffic in the aisles. |
