Re: Build a Structure - Peter Bowen - RGS Timber Trestle
Adding NBWs to Stringers The trestle desk stringers consist of scale 8" x 24" timbers that are assembled 3 wide with spacers and these are then bolted together every 16' - a drilling jig helps to locate the position of the NBW (nut bolt washer) castings. http://www.drgwrr.co.uk/wp-conten...

Re: Build a Structure - Peter Bowen - RGS Timber Trestle
Last minute construction prior to Christmas festivities and a well deserved break from squinting . . . !!! The deck stringers consist of 3 - 8" x 24" x 32' sections with 2" x 6" x 24" spacers. These spacers were added on the prototype to assist in drainage of surface water s...

Re: Build a Structure - Peter Bowen - RGS Timber Trestle
Assembling the two laminated bridge beams on to the two doubled trestle bents requires weights and clamps and a lot of patience to ensure that the components are square and aligned correctly. It is at this point that the structure begins to take shape and great care has to be exercised to avoid dama...

Re: Build a Structure - Peter Bowen - RGS Timber Trestle
Weathering and Bridge sub-structure There is a requirement for the trestle to bridge a road or other right of way and therefore the trestle bents would cause an obstruction, so a raised section is required to allow vertical and horizontal clearance. http://www.drgwrr.co.uk/wp-content/uploads/2014/1...

Re: Build a Structure - Peter Bowen - RGS Timber Trestle
Time for some Nuts N Bolts ...!!! Attaching NBW's - nut, bolt, washer castings - in this case they are 2.5 inch hex nut on a bolt with 4.5 inch washer. These are plastic castings from EDM Models aka Paul Martin at NG Trains www.ngtrains.com/Pages/Details/NBW/nbw.html Each small bent requires 24 fro...

Re: Build a Structure - Peter Bowen - RGS Timber Trestle
A word or two about size and proportion in relation to building the components of a trestle. Bear in mind that the size of timbers used in the construction process are huge and have to carry enormous loads and weight. The main support posts for instance are 12" x 12" square and can weigh a...

Re: Build a Structure - Peter Bowen - RGS Timber Trestle
Production of trestle bents has been moving along slowly in recent days, using weights to hold components while they set is time consuming. http://www.drgwrr.co.uk/wp-content/uploads/2014/12/IMG_6243-1024x768.jpg Patience is the name of the game here, however the results are starting to show... http...

Re: Build a Structure - Peter Bowen - RGS Timber Trestle
Bent construction continued... When I started thinking about this project I knew that it would take a lot of time as each component has to be cut and sanded to fit and it is almost impossible to mass produce items – well it is impossible because I tried grouping a number of pieces together and sandi...

Re: Build a Structure - Peter Bowen - RGS Timber Trestle
A word about cutting 1/4″ x 1/4″ basswood – using a mitre saw or a NWSL Chopper. I had to modify the NWSL Chopper to accommodate larger stock see below: http://www.drgwrr.co.uk/wp-content/uploads/2014/12/IMG_6240-1024x768.jpg http://www.drgwrr.co.uk/wp-content/uploads/2014/12/IMG_6239-1024x768.jpg h...

Re: Build a Structure - Peter Bowen - RGS Timber Trestle
50 Shades of Grey The effects of age and weathering on wood even if it has been treated in some way will result in a grey or silver grey colour. Even cedar which is used in north America for tiling roofs often called cedar shakes will eventually turn from golden brown to silver grey over time. A cl...

Build a Structure - Peter Bowen - RGS Timber Trestle
OK I'm up for a challenge and will (scratch) build a Rio Grande Southern (RGS) timber trestle according to specifications and research of actual construction methods and materials in 1/48 scale for my eventual ON30 D&RGW layout in a spare bedroom. http://www.drgwrr.co.uk/wp-content/uploads/2013/...
