Hamworthy Junction

I have templotted enough of Hamworthy Junction to be sure that it will fit in the garage. The tracks to the left lead to Wareham and Hamworthy.

The single track top right is the Old Road through Wimborne and the double track goes to Poole. In my case these tracks rejoin in the back room then go round one loop of the spiral to reach the hidden sidings.

I couldn't find a railway plan so the Templot is superimposed on an Ordnance Survey map from the 1950s which I found in the museum just off Poole Quay. The main station matches the map but the main line to Wareham curves much more sharply than it should. I may adjust the plan to fit the garage better.

I have had a couple of visits to Hamworthy Junction. The design of the baseboards will have to take the subway into account. I took lots of pictures of what was left. This shows the entrance to the subway from the island platform.

Progress on the new door to give a path from the back room through the garage and into the front room (see Home) has been good as shown below. The insulation of this half of the garage is also complete.

This is the location for Hamworthy Junction. My initial Templot can be seen on the temporary worktop. The actual track level will be closer to the 1 metre radius curve at the far end. This shows approximately how the old road will come in through the wall. The main line to Poole will go through the wall to the left of the double socket.

Both the main line and the old road cross Blandford Road just in front of the radiator. I need to draw the bridges to establish the height of the embankment and then start work on the baseboards.

The baseboard to the left is the entry into the hidden sidings. It sits on top of my O gauge sidings as shown here.

Here is my first trial of 3D printed brickwork. It forms part of the arched entrance to the subway at Hamworthy Junction. It would be too expensive to use 3D printing for all of the brickwork so the flat parts will be etched as shown by my first trial etch to the right of the arch. The brickwork to fit around the arch is currently at the etchers.

I hope to paint the 3D brickwork to match the etch but for the moment it is coloured using a permanent marker to show up the detail.

Here is the real thing.

So far the details have been obtained from a brick count of what remains. However, thanks to Peter Hollins I now have a copy of the LSWR drawings for the buildings on the up platform so I can extend this to include all the brickwork. That will involve of lot of drawing!

The etched brickwork has arrived and is shown below against the 3D printed arch. Unfortunately the etch is not laying completely flat but the 3D bricks fit perfectly inside the etch. I started by drawing the etch in 2D and then imported that into Cubify Design as a starting point for the 3D model. I made a mistake on the left column of the etch in that I assumed only half etch interleaving brickwork when in fact I used full etch. Had I used half etch the end quarter brick would have fallen off! I will have to reprint that with an extra 0.005" relief.

The additional etch overlay at bottom left has to be chamferred on its top etch and soldered to the brickwork to represent the cement render beside the steps. The steps will probably be etched as well to include fold lines and a half etch groove to locate it into the bottom of the render.

The next job is to prime and paint the scrap left column as a trial.

I have adjusted the left hand column and reinforced the etch at the back with 2mm x 4mm brass strip. The 3D print is temporarily fixed with sellotape at the back. I need to progress the artwork for etching the other side of the wall and solder that up before I can fix the 3D into its pocket and then try priming and painting.

I used a permanent marker to colour the 3D print shown previously but when I tried to prime it the primer just curled up into little balls and rolled off. I won't be doing that again!

I am grateful to Peter Hollins who provided me with a 40' to 1" plan of Hamworthy Junction. I have had it digitally scanned and I have reworked my Templot with this plan on the background. There is still more detailed work to be done but I have printed the Templot and laid it out in the garage in preparation for cutting the track bed from 9mm plywood. A trip to B&Q beckons! The scan will find it way to a South Western Circle portfolio later this year.

Here are a couple of pictures of the layout. The first view is from the new door, seen in earlier pictures, and shows the main line to Wareham swinging round to the far right and the Hamworthy branch which will disappear through the wall to the left.

The next view is from the original doorway seen in the previous picture. I have added a new door frame and rehung the door to swing away from the garage rather than into it. This gives more clearance for the Hamworthy Junction layout. In this view the Old Road swings to the left and the main line to the right. Both disappear through the wall to the laundry room.

I have been busy building baseboards for Hamworthy Junction. The following pictures show progress from roughly the same positions as above.

The second picture also shows a new hole through the laundry room wall for the main line to Poole. There is a well in the baseboard between the old road and the main line. Blandford Road passes under both lines. I am currently working on artwork for the bridge under the main line. Most of the brickwork will be etched but some of the more complex shapes will be 3D printed.

I have switched to 9mm hardwood plywood from B&Q for these baseboards instead of 6mm birch ply. I am using 33x33mm blocks and screws to hold it all together. The design was inspired by some baseboards built by 3mm member David Thompson at one of our Modeller's Weekends. I'll get some pictures next time I have them up-ended. The projections at the front have to be trimmed for the embankments, and a fascia added. The framing at the back adjacent to the hidden sidings also needs completing.
