Learn Operating Sessions  (Hands-On)   presented by A. Dodge           Friday (8/24) 8:30 – 11:00

You will drive to Andrew Dodge’s P48 layout (you will need a car to get there), where he will teach you all about operating sessions.  Newcomers welcome! If you’ve never done an operating session before, Andrew will teach you how to hold a session with other attendees on site.

Registration is limited AND required. PLEASE EMAIL TO REGISTER.

C/MRI                                                    presented by J. Beckham                    Friday (8/24) 9:30 – 11:00

This clinic is an introduction to Computer Model Railroad Interface. Some of the content is provided by Dr. Bruce Chubb. It will cover some fundamental electronic and electrical information as it relates to C/MRI. Also, it will cover the basic parts and wiring that are used to provide signaling and the operation of a CTC system. I will also cover some alternative circuits that relate to C/MRI. It will not cover JMRI or LCC.  A Q and A session will be available at the conclusion.

Weathering Rolling Stock              presented by J. Taverna                       Friday (8/24) 9:30 – 11:00

in this hands-on, extra fare clinic, you will be able to draw, prepare and print an O Scale B&O Concrete Whistle Post and leave with it in your hand by the end of the clinic! Since it is a simple form, the whistle post is a perfect introduction to 3D design. After you have finished your drawing, it will be prepared for printing, then loaded onto a desktop 3D printer for the final step – printing! CLICK HERE TO REGISTER.

Washington Trolleys              presented by J. Hogan                                     Friday (8/24) 12:30 – 2:00

Jim Hogan offers a 35mm color slide program on the Street Cars in Washington.  A longtime resident of the District of Columbia, he has spent decades acquiring the material that is to be presented.  As a boy, he spent many hours riding D.C. Transit street cars around town and offers his observations on the experiences he had.

DCC                                 presented by M. Herman (Loksound)                     Friday (8/24) 12:30 – 2:00

A beginner’s overview of LokSound decoders and how to change CVs with and without the ESU LokProgrammer.

Cardstock Structures (Hands-On)           presented by J. Gore                     Friday (8/24) 12:30 – ???

Jim Gore, the test builder for Clever Models, will be presenting a clinic on building cardstock structures. Participants in this clinic will build a shed, guided every step of the way by Jim.  Cardstock structures are an inexpensive way to get additional buildings for your layout. These are not the lithographed, 3 or 4 color, tab and slot buildings that you may remember from your youth; but structures more akin to a craftsman kit. However, they are more forgiving that a craftsman’s kit in that if you ruin a part, you can print out another one and start over.  This clinic will be held Friday of the convention just after lunch, and participants can keep building into the night if they wish!  CLICK HERE TO REGISTER.

Proto 48                                                         presented by J. Lincoln                 Friday (8/24) 2:00 – 3:30

Build a King Post Truss (Hands-On)       presented by R. Hunter                Friday (8/24) 2:00 – 6:00

Join Maureen and Rick from Hunterline, as they take you through, step by step instructions, to build your own Hunterline 30’ King Post Truss Bridge in your scale (N, HO, S, O,including all the Narrow Gauge scales). CLICK HERE TO REGISTER.

Traction Modeling                                         presented by J. Hogan                 Friday (8/24) 3:30 – 5:00

Jim Hogan has been engaged in O-scale trolley modeling for the past 35 years.  In addition to a home layout which he constructed to fit within a small spare bedroom, he helped construct the demonstration O-scale trolley layout at the National Capital Trolley Museum.  He has been a longtime member of the East Penn Traction Club and the Baltimore Society of Model Engineers.  His talk will illustrate several aspects of traction modeling in O-scale, ranging from off-the-shelf approaches to kit bashing and/or scratch building of streetcar models, track and overhead wire.  He will give examples of a lower cost approach to getting started and will furnish a listing of information contacts.

Why O Scale?                                            presented by T. Terrance             Saturday (8/25) 8:00 – 9:30

It’s actually a great time to be in O Scale!  A brief history and survey of our corner of the model railroading hobby will set the stage for why today’s models are far superior to what was available in the past.  And how today’s selection – including legacy models still readily available – allows anyone to model just about any prototype.

Layout Planning and Design                 presented by A. Dodge           Saturday (8/25) 8:00 – 9:30

This clinic will examine the wide range of topics a modeler should consider before going to the
hobby store and commencing construction of a layout. Topics will include geographic location,
era, type of layout, how much is enough or too much, layout room issues, pointers on
construction, and space management and environment.

Build a Loading Dock (Hands-On)       presented by B. Blackwood   Saturday (8/25) 8:00 -9:30

In this clinic you will build the ITLA Models Loading Dock Interior Kit (ITLA will provide their kit # 05159 Loading Dock interior kit. Retail $21.99) Things you would want to bring: hobby knife, sanding supplies, water based acrylic, wood glue.  CLICK HERE TO REGISTER.

Building in Plexiglas                               presented by A. Dodge            Saturday (8/25) 9:30 – 11:00

This clinic will introduce modelers to what is possible with Plexiglas as a building material and
walk the modeler through the simple process of fabrication. Constructing the base structure of a
model building using Plexiglas is one of the easiest methods available. Plexiglas provides a
superb foundation for scratch built buildings that will not warp, absorb moisture, and provides its
own window glazing. It only takes a few minutes using any type of table saw to cut out the parts
for a structure. Plexiglas is also modest in price, and it can take the place of making mock-ups
that usually end up in the trash. If you are interested in learning how to scratch build a structure
the easy way and seeing some of my projects, please join me for my Power Point program.

Tree Building                                             presented by R. Kilday             Saturday (8/25) 9:30 – 11:30

Convert 3 Rail Equipment to 2 Rail: Why, How and Upgrades     J. Sethian   Saturday 9:30 -11:00

Improving Commercial Models           presented by D. Friedlander     Saturday (8/25) 12:30 – 2:00

O scale is chock full of RTR models.  Most of these models are constrained for various reasons in how faithfully they represent their prototype, but provide us a great base of which we can model upon. Research can be equally important to the actual detailing. This presentation will highlight the steps and resources I use to research and super-detail my models. Some before and after models will accompany the presentation.

Transit Modeling in “O”                        presented by J. Lorenzen           Saturday 12:30 – 2:00

How to Purchase O Scale on the Secondary Market    J. McGarry         Saturday (8/25) 12:30 -2:00

Update on the Aquia Line                     presented by B. Kempinski         Saturday (8/25) 2:00 – 3:30

Dead Rail                                                   presented by D. McRee                Saturday (8/25) 2:00 – 3:30

O scale is ideal for Dead Rail or Power-On-Board.  It has plenty of room for batteries and radios.  In this clinic I will discuss the different systems available and show examples of installations from tiny On30 engines to MU’ed standard gauge diesels.

Scenery                                                       presented by B. Geldmacher      Saturday (8/25) 3:00 – 5:00

Our clinic will start with a discussion and demonstration on casting rocks and other features using Hydrocal and Woodland Scenics’ rock molds. We will also show attendees how to create their own unique rock molds using latex rubber. We will then move on to the creation of basic land forms and scenery structures using extruded foam board and cardboard strips. We will demonstrate how to cover these basic structures using plaster cloth, Structolite and Sculptamold and show how to install, color, and weather the rock castings made earlier in the session

We will finish our diorama with a discussion and demonstration on a variety of ground foams and foliage available to the modeler and how to apply those products using Matte Medium and other adhesives. This will include a demonstration of the mythical Static Grass Applicator using a variety of static grasses and materials. Lastly, we will show attendees how to make their own grass tuffs and pathways using the Grass Applicator.

Mold making and Casting (Hands-On)       presented by J. Beckham     Saturday (8/25) 3:30 – 5:30

This clinic will cover the basics of producing one part rubber (RTV) molds from scratch built or other masters.  It will also cover making castings from the molds using two-part resin and plaster.  Participants will be furnished a master and rubber to make a mold.  Due to the time it takes a mold to cure, they will take their mold with them and can remove the master the next day.  The master will be an O Scale item useful to most model railroaders.  They will also be supplied with a cured mold of a different O Scale item and will make one or two castings using two-part resin supplied.  The can try using plaster at home as it would be too messy to do.  I will, however, demo making a plaster casting.  Time permitting a demo of two part mold making will be presented.
