Simfire

This is the modelling part of a larger article - that I'm still putting together.

Spent a morning doing pencil sketches, which don’t scan at all well. Also makes you realise how complicated the various bits are.   
Decided it would be a good idea to start on the simple stuff & work fwd, so made a start on the laser detectors.
In theory, they’re a simple box, with a glass front, but then, take a close look at the photo. Notice the rounded corners on the box, the shade at the top. The lens behind the window, the 8 screws around the window, the short stalk on top, the longer stalk below, the mounting arrangement – 91179-091181-1 –

The Box - Decided to use some Evergreen Rectangular tube as the basis – 6.3mm X 9.5mm, cut into 11mm lengths (X4) to form the main box section. To create sides, I cut up some 2mm sheet to fit the ends/sides (X8). Glued 1 piece in each box, to act as support for next operation.
Front Window - Marked edges of windows on front side – inset 1.5mm approx.. Placed in vice, drilled 1mm hole at corners, then drilled line of holes along the window edges. Cut along the lines to separate the window panel – keep this piece.
The Lens - To replicate the lens (the actual lazer detector) I took a clear 5mm LED & cut the top off it, just above the internal metal bits. Keep the top, discard the base. Glue the top to the window panel cut out that you kept. Glue it into the box, centre. Fit the 2nd 2mm sheet end/side.
Rear Overhang - Using more 2mm sheet, cut a 5mm X 11mm piece (X4). Glue it to the upper back of the box. Draw a line down the centre of the 11mm axis. This line forms the most rearward point, much like the bows of a ship. Grind/file/sandpaper the excess plastic to form a point. More plastic needs to be removed, from the top this time. The underside of the overhang is where the system wiring attaches, a mentioned above there are no really good views of this, but – Simfire 5 & 6 are best – 91183-291185-3
The Stalks – round protrusions top & bottom, the top one very short – 1.5mm approx., bottom one longer – 3mm approx., used more Evergreen Rod & Tube Assortment to replicate these, not sure of the exact size. Bottom one needs to nest in the next size up, to provide lateral movement of the detector. The larger sized tube was glued to a 10mm length of 2mm X 2mm rod.
The Shade – a piece of 1.5mm X 2mm rod was cut & glued side on to the box above the window, edges cut & rounded.
Build pics are few & far between – 91187-491189-5– one near complete detector, just missing the window & 3 X boxes, one end & window cut only
91191-6 – at night
91193-791195-891197-9- early morning
Applied some paint - Humbrol 67 – 91199-1091201-1191203-12– late afternoon

More to come next week

Bit more done
I mentioned above “The underside of the overhang is where the system wiring attaches “ but didn’t actually progress that – have now, drilled a 1mm hole in each, to attach the individual wires – 91205-0 –
Made more of the ‘stalks’ above, plus mounting rods. The rods are 12mm X 2mm X 2 mm – the individual parts laid out – 91207-1 – also shows the LED cut – parts partially assembled – 91209-291211-3– top stalks added – 91213-4 -  shades cut (11mm X 2mm X 1.5mm rod) – 91215-5 – glued in place – 91217-6 –
End blocks made (2mm sheet) – 91219-791221-8– paint applied – 91223-9 – mostly assembled – 91225-10 – added window sheet – 91227-1191229-12 –

As you will note 3 have an open left side – though I painted the exterior of the end blocks, forgot to paint the interior, which meant I couldn’t seal them up. Still need to apply putty & tidy them up
