Black Bear Six Leg Trestle Kits, TJK-6xHO
Standard Gauge, HO Scale |
|
|
Just about any timber trestle built in the last 20 years looks like one of these kits. All the trestle bents have six legs - making them appropriate for any modern setting. You can build the bents with round legs or square legs - with ballasted deck or open deck.
Trestles built by the Santa Fe (AT&SF) have some unique details, so those kits are listed separately. Trestles built by the SP, WP, UP, Pennsy, and others are very similar and are grouped together.
Both pile bents and frame bents were used by most of the railroads. The jig that comes with these kits includes the Leg Cutting Guide, so you can easily model any protoype you wish.
Construction Jig and Instructions
This kit comes with the 6-leg assembly jig. All the instructions, drawings, and documentation you need are included with the jig. Twelve pages of step-by-step instructions show how to build prototypical trestle bents with square or round legs in pile or frame bent configurations. The instructions also show how to install the trestle in a layout. Two full size drawings show you how to build double tall and double wide trestle bents. The jig can be purchased separately if you already have all the wood you need.
Materials Pack
Wood is supplied in bulk - 24" long pieces. That makes it easier to build long and tall trestles. There is enough bracing material to install diagonal braces and girts throughout the trestle. If you want to build a trestle twice as tall, buy two materials packs. If you want to build a double track trestle, buy two materials packs. If you want to build a double track trestle twice as tall, buy four materials packs. You can buy as many materials packs as you need without having to buy another jig.
NBW Pack
NBW's are not included with the kit. An NBW Pack (TJN-N) for HO scale trestle kits is available under HO Scale Kits > Accessories.
