Issue 76 - Contains the induction box cowls, the forward wing, vortex generators and screws., and has instructions for preparing the induction box cowl, attaching the vortex generators, assembling the induction box cowl, and attaching the main cowls to the body.
Prepare the induction box cowl - Test-fit the two halves of the induction box cowl together to identify the contact areas, then lightly sand off the paint from the large contact area identified. Take great care not to damage the thin tapered end.
Gently use the back of a craft knife to scrape off the paint ftom the interior notch as shown in the steps.
Repeat on the opposite side of the induction box cowl.
Attach the vortex generators - Use the back of the cutter to scrape the paint off the pins as shown. To identify the left-hand vortex generator, check the mouldings for two moulding marks at the points shown, (the moulding marks should be on the underside).
Test-fit the two pins carefully through the holes in the left-hand cowl. If necessary, clean off a little more paint until the support legs of the vortex generator fit flush.
Working on the inside of the cowl, apply a very small amount of ABS adhesive to both holes, then immediately refit the vortex generator and lay the assembly down to allow the glue to harden.
Assemble the induction box cowl - Use a cocktail stick to apply adhesive thinly to the flat contact areas and locating pins on both parts of the induction box cowl. Gently press the halves together until the glue bonds, avoiding the vortex generators and ensuring there are no gaps.
When the glue has set, gently scrape the paint off the oval socket on the edge under the thin tail of the induction box cowl, where the forward wing fits. Gently scrape the paint off the square lug projecting up from the wing itself, and along a thin line down the centre of the wing.
Test-fit the wing to make sure you have cleaned the contact areas thoroughly. The forward-facing lug arrowed yellow fits into the socket circled in yellow, and the upward facing lug fits into the socket as shown.
Separate the parts and apply general-purpose adhesive sparingly to the contact areas. Fit the wing back in place and press the parts together until the glue bonds. Make sure that the wing is level, and aligned at right angles to the centreline of the cowl.
Support the assembly on the corner of a small box (about 30mm high) and leave for 24 hours to allow the glue to harden completely.
Attaching the cowls to the main body - You will need the main body from Issue 75 and the lower engine cowls from Issues 61 and 63, plus the flipups from Issues 62 and 64 and the flip-up supports from Issue 36.
Test-fit the lower left engine cowl in position, without glue. Make sure you can locate it easily without leaving any gaps. Repeat with the other cowl.
Check that both cowls clear the rear wishbones. Note, if one wishbone seems to be about 1mm higher than the other, the engine may not be seated correctly. If so, loosen the two screws that hold the engine (as shown in Issue 74, page 13, Step 4). Lift the engine a little and push it back down, moving it gently from side to side until it is properly seated.
When both wishbones are about the same height, you may still need to trim the arches in the cowls a little with a sharp craft knife so that they do not touch the wishbone.
Apply general-purpose adhesive to the edge of the left cowl indicated by the yellow line. Do not glue the arch. Place the cowl back in position and hold it until the glue is firmly bonded.
Secure the cowl in position with masking tape on the inside. You may need to add some to the outside at the rear, but make sure you remove any excess glue first.
Repeat for the right cowl and leave the tape in position for 24 hours.
Apply ABS cement to the bottom of the left flip-up support (note that they are marked with an L and R to indicate left and right) and place it in position. Make sure that the support is the right way round and that the two pins fit into the matching holes in the underbody.
To make sure that the support is in the correct position, immediately fit the left flip-up on top of the support and cowl, without glue. Make sure that the flip-up is seated on top of the cowl and that the support is correctly located in its recess. Leave the assembly for the glue to set, holding the ip-up with tape if necessary.
Remove the left flipup and apply general purpose adhesive along the top of the cowl, on top of the flip-up and the recess in the engine cover as shown, where you earlier removed the paint.
Replace the flip-up, making sure that it is correctly seated on all three components. Hold it in place until the glue has firmly bonded.
Repeat to fit the second flip-up support and flip-up on the right-hand side of the model.
Hold all the parts together firmly with strips of masking tape and leave for 24 hours for the
glue to harden fully.
That's it for this stage, carefully store these assemblies, together with the unused screws, until you need them to continue the assembly.
