Black Bear Trestle Kit, TJK-4DOn30T
On30 Narrow Gauge, O Scale, Denver & Rio Grande Western Style Trestle Bent - Includes Tall Trestle Jig

This kit is specially designed for On30 modelling. The design is based on typical D & RGW narrow gauge trestles. The leg spacing has been adjusted to line up with On30 track, just like it should.

This kit comes with everything you need to build a 47' tall x 120' long trestle.

The tall jig that comes with this kit makes it easier to build tall, true frame bents.   If you want to save a little money, you can build a similar trestle with the short trestle kit:  TJK-4DOn30S

Scale Size:
47' Tall x 120' Long

Actual Size:
11-3/4" Tall x 30" Long

Typical Bent Spacing:
12' to 15' (3" to 3.8")

This is the same materials pack that comes with the other Black Bear D&RGW, O scale trestle kits.








YOUR CHOICE OF CONSTRUCTION TECHNIQUES
The FALSE FRAME BENT has the look of the prototype without the difficulty of construction. The NOTCHED FRAME BENT looks like the prototype but is much stronger. The legs are continuous from the top cap to the ground. The TRUE FRAME BENT is prototype modeling at its best. You will be surprised by how easy it is to build this bent.

Construction Jig and Instructions
This kit comes with the new "4-leg" assembly jig that allows all of the above construction techniques. A FRAME BENT is characterized by horizontal sills that interrupt the vertical legs. They were common in southern Colorado and New Mexico where the trees don't grow as tall as the do in other parts of the country. All the instructions, drawings, and documentation you need is included with the jig. Eight pages of step-by-step instructions show how to build the bents and install the trestle in your layout. A full size drawing shows you complete details of this classic narrow gauge trestle design. 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. If you want to build a trestle twice as tall, buy two materials packs. If you want to build a trestle twice as tall and twice as long buy four materials packs. You can buy as many materials packs as you need without having to buy another jig.

NBW Pack
An NBW Pack (TJN-S) for O scale trestle kits is available under O Scale Kits > Accessories.
