In this stage you bring together the top and bottom of the starboard mandible. The two sections are held together with side frames and you use five of these this time – two SF-08s and three SF-09s. The side frames have countersunk screw holes in them into which you insert countersunk screws, 20 in total this time, that screw into lugs in the top and bottom frames of the mandible. After you’ve brought them together you cover the frames with four sections of panelling – SP-15, SP-16, SP-18 and SP-19. These are glued in place.
Two SF-08 side frames (mandible) supplied with Issue 77
Three SF-09 side frames (mandible), one of which was supplied with Issue 77 and two with Issue 78
20 countersunk screws supplied with Issue 76
Side panel SP-15 (mandible) supplied with Issue 77
Side panel SP-16 (mandible) supplied with Issue 77
Side panel SP-18 (mandible) supplied with Issue 78
Side panel SP-19 (mandible) supplied with Issue 78
Tools and other items needed
If you do everything that is described in the Stage 78 Assembly section of the magazine you will need the following:
Screwdriver supplied with Issue 2, or similar.
Cyanoacrylate instant glue, also known as superglue
Adding the side frames
You use two SF-08s and one SF-09 on the longer, outside edge of the mandible and two SF-09s on the shorter inside edge. Make sure you get the side frames the right way round so that the countersunk holes are facing you and facing out from the mandible when you look at the assembly from the side. Fitting all five side frames to the lower part of the mandible should not be unduly complex. When you’ve done that, position the upper part so that the countersunk holes in the side frames align with the lugs in the mandible frame (with the lugs on the inside) and insert the remaining 10 screws. You might need to gently push the upper part from its curved end to get the screw holes and the lugs to align exactly. Make sure all 20 screws are done up tight as they are covered up when you attach the side panels.
Adding the side panels
You can apply glue both to the holes in the side frames and the lugs on the side panels that fit into them, just make sure that the panels are not loose after you’ve stuck them down. The order you add them does matter as on the shorter side SP-18 has a recess that fits over the end of SP-19 (so SP-19 goes on first) and on the longer side the end of SP-16 fits over the end of SP-15 (so SP-15 goes on first). While you are working on the mandible, watch that you don’t handle it roughly, being particularly careful not to dislodge or damage the pipework and other details that you attached to the lower side.
Tidy up and store
Put the assembly away somewhere safe and store the sprues supplied with this issue but not used this time back in the parts pack so you know where to find them.
