I refilled the gearbox with fresh oil. I can't fit the gearbox cover until I have refitted the gear lever' I mad full size cardboard templates for the dash panels and mapped out the instrument positions for the centre panel
Yesterday I shortened the gear lever by about ½", so that the new extension fitted as close to the anti-vibration bush as possible. John Hopkins had promised to fit and pin the extension in place once I had cut the gear lever to length, so I took it round to him. John manufactured a taper pin, accurately drilled a hole through the centre of the extension and the gear lever, reamed the hole to match the taper pin. He locked the extension in place with Loctite, inserted the pin and cut it off flush with dies of the extension. A light dressing with a file and you could hardly see where the pin had been inserted. I picked up the completed gear lever today and refitted it to its gearbox mounting. I then refitted the complete assembly back on to the gearbox. I did a further trial fit of the gearbox cover to check the clearances around the hole for the gear lever now that it was fitted. While I was doing this I noticed an oil leak from the back of the gearbox. I will investigate later.
I cut out the dash centre panel.
I needed to bend 10mm flanges around the centre dash
panel I made some bending bards from 25mm angle iron. These formed
extensions to the vice and bolted together at the ends to clamp the panel
between them. I inserted the panel to the line marked 10 mm from the edge
and clamped it in place. I checked that the line exactly matched the
line of the bending bars along its length. The initial bend was
started by hand applying pressure to the base of the plate, just above the
bending bars. The final bend to to a right angle was achieved with a
hammer and a block of wood. The block of wood protects the panel from being
dented by the hammer. The result is a clean straight bend. I
repeated this for each edge of the plate. When I had finished the dash
panel was an exact fit between the panel brackets on the bulkhead.
Central Dash Panel
Using the the full size template I made as a guide I
marked the instrument positions on the dash panel. To cut then out I
had the choice of using a hole saw or to drill holes around inside the the
circumference of the instrument hole then cut these to break out the centre.
?the dash panel metal was very thin and I thought the chance of making an
error using the hole saw to great a risk so I opted for the old
fashioned method. I drilled around inside the circumference of the
instrument holes using the pillar drill making sure each hole was inside the
line. I cut out the holes for the Rev counter and Speedo with a junior
jack saw blade inserted in the holes and cutting the spaces in between.
In opened out the hole to the correct size for the instrument with a half
round file frequently checking the hole against the instrument until it
fitted. The Rev counter and Speedo are from the donor XJ6, I had had
them refurbished by "Speedy Cables" ages ago. They are retained by
spring pressure against 3 lugs inserted through slots in the panel and
held by twisting the instrument so that the lugs are behind the panel.
I used the dashboard of the XJ6 to as a template to determine where the
slots should be cut. marked them on the dash pane l and checked them against
the instrument. The slots were cut with a junior hacksaw and small flat
Central Dash Panel
I cut out the 4 remaining holes for the fuel, oil , water
and voltmeter gauges. I opened out the holes to size with a half round file
frequently checking against the instruments until they fitted.
these instruments are retained using U brackets fitted to the back of
the instrument to clamp then in place. Now the holes were cut I put a
strip of masking tape down each side, at the back of the panel, where
the brackets will fit. I put the panel in place and using a bolt
dipped in engineers blue, inserted though the panel mounting holes in the
brackets, marked where they came on the panel. I drilled the
panel to match the holes. I temporarily removed the dash panel brackets from
the bulkhead and fitted M5 alloy Rivnuts to them to secure the panel. I
refitted the bracket and fitted the peel using M5 pan head set screws.
Using rivnuts certainly made the job easier that trying to fit nuts to the
screws from behind the panel. I took the panel off and fitted the
instruments. I make sure the Rev counter and Speedo are mounted vertically I
will need to fit a stop at the back of the panel to prevent the top lug from
going past he vertical. I temporarily fitted the panel with the
instruments just to see what it looked like.
I made a couple of stops out of 10mm aluminium angle. I checked the instruments were vertical and positioned the stop against he top lug. I marked its position I removed all the instruments and drilled the panel, I secured the stop in place with a small pop rivet. I refitted the large gauges and checked that they were vertical against the stop. I gave the panel one coat etching primer and two coats of Hammerite smooth black and left it to dry.
Whist the paint is drying I took the gearbox cover off to
investigate the oil leak. I discovered two missing bolts at the back
(probably removed when I removed the original XJS mounting bracket. I will
need to get some M8 x 60mm bolts in the morning to replace them.
Though Wednesdays is my day off from work I never seen to
get as much done on the car as I would like. I got some M8 bolts for
the gearbox and fitted them. It seems to have fixed the leak. I
say leak but it was more like a weep from the joint. I can't remember
for sure, but I think the most likely cause for the missing bolts was when I
removed the XJS mounting bracket. I finished painting the dash
centre panel and refitted the instruments, finally fitting the dash panel on
to the mounting brackets . I have sealed the transmission cover
to the rear bulkhead and left it to dry. I made a cover plate for the LH
inspection plate in the rear bulkhead. I painted it in Acid #8 etching
primer and left it to dry.
Painted the bulkhead cover with 2 coats of Hammerite Smooth Black
Fitted the rear bulkhead cover
I was determined to finally fit the gearbox cover today,
The gearbox oil leak is definitely cured. I did one last trial fit
tightening down add compressing the seal to make sure that
the holes in the cover for the gear lever and handbrake lever were big
enough so that no contact with the cover occurred whine the levers were
operated. As I tightened the bulkhead bolts I though I felt the top
one go slack as I tightened it down . Sure enough, I found when I
undid the cover and removed it, the top rivnut had once again pulled through
the bulkhead. The hole was too badly mangled to insert another
Rivnut but I had an alternative solution - Make a captive nut and pop rivet
it in place. I inserted an M8 Rivnut in to a piece of 30mm strip
aluminium 60 mm long. the rivnut was positioned to correspond with the hole
in the bulkhead, I drilled a hole 10mm from each end of the
aluminium strip to accept a 3mm pop rivet. I positioned the
strip in place from inside the cockpit, aligning the rivnut with the hole in
the bulkhead. I drilled through the pop rivet holes in to the
bulkhead. I painted the aluminium strip back so it would not show.
When it was dry I positioned the "captive nut" on the engine bay
side of the bulkhead and held it in place with a short M8 bolt.
I aligned the pop rivet holes and riveted it in place While I was
waiting for the paint to dry, I fitted the rubber (sleeve) grommet to the
speedo cable securing it with a cable tie at he bottom. I'll fit
another to the top once the speed cable and cover are finally in
place. Because it was going to be easier without the gearbox cover in
place I checked and adjusted the clutch release clearance (HM Xj6 Series 3,
I checked all the bulkhead rivnuts and all were secure. I trial fitted the gearbox cover again to be satisfied all the clearances and securing hole alignments were correct. I removed the cover one more time and placed sealer on e transmission cover n the area that would be overlapped by the gearbox cover. I finally put the gearbox cover in place, threading the speedo capable though the hole in the top if the cover and making sure the rubber grommet was in place protecting the cable. I inserted the bulkhead bolts first partially tightening them until I could insert the floor retaining bolts. I partially secured the cover to the floor with M5 bolts and plain nuts from underneath the vehicle. This is a two person job and Mary helped me by holding the bolts in place in the cockpit floor while I worked from underneath. This established the position of the gearbox cover and transmission cover. To get to the final position with the seals compressed and the gearbox cover , / transmission cover joint sealed Greg came over to give me a hand. We systematically worked from the bulkhead backwards tightening each bolt. Once it was all tightened down and in position we replaced each of the floor bolts (one at a time) with M5 x 25mm pan head screws, 2x penny washers (1 x above and below) and nyloc nuts. this latter exercise was to make the fastening easier to hide under the carpet when the car is trimmed. I fitted the speedo cable to the speedo routing it from the exit point in the gearbox cover thought the upper part of the bulkhead near the RH demister pipe through a hole behind the speedo to back of the speedo.
The rest of the day I started to look again at the dash
I spoke with Nostalgia again to day regarding the dash side panels. I wanted to make sure that when we spoke a few days ago we were not at cross purposes, we weren't I seems that now they use wooden dash panels, they overlay the wood panel on the centre instrument panel, but use just wood with no metal under panel for the side panels. However since I need to get the car electrics and engine running before the car goes for finishing at Nostalgia I will need to make a dummy panel fro the drivers side. because that is where I want to mount the warning lamps and the light, heater and fog lamp switches. Once the electrics are proven then the "trimmer can transfer the lamps and switches to the wooden panel. I spent he day making a cardboard template of the panel and then cutting out and bending the panel to shape from 20 gauge aluminium( Build Manual fig 3-27) I transferred the template outline to the aluminium panel checking the dimensions against the drawing and the vehicle. This was important because the dimensions, given on the drawing, for the steering column housing was misplaced by 70mm and too shallow when compared with the vehicle. The panel was easy to cut out and with care, using the bending bars I made for the centre instrument panel, I was able to bend the flanges. A couple of trial fits were to get the end of the panel to match the underside of the scuttle. The panel almost fits, I have to decide on the how to make some distance pieces between the panel and the scuttle mount to get the position right and then if I need to make a cut out in the panel for the back of the ignition switch.
I decided to make a cut out at the bottom of the panel
for the ignition switch. From all the trial fits of the panel it looks
like I need one. The barrel of the ignition switch is about 35mm I
placed the panel as close to the final position as I could get, and marked
around the ignition switch on to the panel. I did the usual trick drilled a
number of holes around the circumference, just inside the line. I cut
between them with a hack saw, finishing off the cut out, to a smooth
semicircle ,with a half round file. I did a guesstimate of the size of
the distance piece I need to bridge between the panel and the mounting
bracket. As near as I could tell 30mm should do it. I made
a "U" channel from an off cut of aluminium sheet 20 mm x 30 mm x 20mm.
I found it easier to work with the steering column unbolted from the
mounting brackets and lowered to the floor of the car. I drilled
the scuttle mounting bracket and inserted 2 x M5 Rivnuts. I put the distance
piece in position on the scuttle mounting bracket and clamped it in place.
I dipped an M5 bolt in engineers blue and screwed it in from the back until
it touched the distance piece. The resulting mark showed where to drill the
distance piece. I drilled the two holes with 5.5 mm drill and bolted
the distance piece in place. A trial fit of the panel showed the the
distance piece to be too big. I wont bore you woth the detail but I made a
distance piece this time 20mm x 25mm x 20mm but this also proved to be too
big. To get it right I inserted two long M5 bolts from the back. With
the panel in the correct position the bolts were screwed in until they just
touched the panel. I measured the length of the bolts , 22 mm
Throughout the day at each trial fit I found I needed to adjust the panel to
fit around the brackets and the underside of the scuttle to achieve the best
fit I could.
Dash side Panel
So that my hard work of yesterday was not a complete waste of time I made a new distance piece by combining the two I made yesterday. I cut off one leg of the "U" on each distance piece to make an "L" bracket . I trimmed the "L" to dimensions of 20mm a 18mm. The 18mm legs were overlapped and clamped together to make a "U" channel 20mm x 22mm x 20mm. I drilled 2 x 4mm holes in the overlapping brackets and fastened them together with pop rivets. This time the trial fit was satisfactory. With the panel in its correct position, I drilled two pilot holes through it and the distance piece, taking care that it did not interfere with the pop rivets or the securing bolts holding the distance piece to the scuttle bracket. I too the panel and distance piece off and opened the holes in the panel to 5.5mm. I inserted 2x M% rivnuts in the distance piece to secure the panel. The distance piece was proving difficult to fit to the scuttle bracket because the "U" channel was too narrow to get my fingers in to start the screw thread. I overcame this problem by drilling holes in the opposite side of "U" channel through which I could insert a screwdriver and securing the distance piece to the scuttle bracket with M5 Screws.
Now that the panel is in position I marked the position of the mounting brackets and any other obstruction like the demister vents on to the panel. this gave me the free areas where I could mount the switches and warning lights. Adopting the driving position , as best as I could without seats , I marked where I could easily reach and see where the switches should go. I repeated the exercise to make sure I could easily see where the warning lights. should go. The switches were placed just to the right of the ignition switch, 2.5" (63mm) from the bottom of the panel and at 1.5" ( 35mm) centres. the warning lights were mounted in a 3x3 matrix at 1" (25mm) centres, centred on the steering column and visible through the steering wheel. I fitted the switches and the warning lamps and trial fitted the panel again to check the positions. It looks and feels OK.
The panel is only a temporary to enable me to plot the position of the instruments, switches and warning lamps and complete the wiring. If any of it is incorrect or turns out to be obscured in any way it can be adjusted once the wooden dash is fitted.
This entry began last Wednesday and is the cumulative
total of 2 hrs here and there since then. I started work on the
vent boxes in the front wings. Using my usual habit of marking on to
masking tape I masked up the vent indents. Using some 10mm aluminium strip
placed against he edge of the indent I marked a 10mm border around the edge.
I drilled 4 holes in each corner to and joined then up to form a right
angled slot big enough to take the blade of a pad saw. I cut out the
inner rectangle just inside the border line. I opened out the hole up
to the border line to make a 10mm flange all round the hole. the
flange is used to bolt the front of the vent box to the body. I
positioned the vent box inside the wing and lined up the front with the hole
in the wing, The vent box fits with the sloping edge at the top and
the operating lever point rearwards. I clamped the vent box in place
with some small "G" clamps. From inside the car I marked where the fixing
brackets came on the bulkhead and how much of the bracket overlapped the
side of the bulkhead. I took the vent box off and drilled the
fixing brackets with 2 holes in the rear bracket and one in the front. I
fitted 3 x M5 Rivnuts in to the bulkhead holes and fitted the vent box with
3 x M5 pan head screws. I clamped the front face of the vent box
to the wing I marked the centre of centre of the flange, top and
bottom, I drilled through the wing in to the vent box with a 4.5 mm drill
and secured the vent box with 2 x M4 x 15mm, countersunk screws and nyloc
nuts. I marked 2" (50 mm) from the top and bottom of the vent box indent and
drilled through these points in to the vent box. I secured the
sides of the vent box with 4 x M4 x 15mm , countersunk screws and nyloc nuts
I repeated the operation for the RHS vent box and will
continue to fix it to the front wing tomorrow.
It was Mary's birthday today so I had limited time to work on the car. I had made sure that the vent box was aligned with the aperture in the wing clamped it in place. this was slight departure from how I had positioned the LHS vent box and an attempt to centralize the vent box around the hole and thus get the holes to be drilled in vent box more central. I marked and drilled the rear fixing brackets and with the vent box in position drilled the fixing points in the bulkhead. I fitted 3 x M5 Rivnuts to the bulkhead. On testing the position of the vent box by fitting the flap I discovered it was too low.
To make the best use of my limited time I cut out and drilled the remaining inspection plate to be fitted to the RHS of the rear bulkhead.
I finished making the inspection plate and fitted it to the rear bulkhead with 5 x M5 x 20mm pan head screws and M5 Rivnuts. I removed the plate, degreased it and painted it with Etching primer , followed by 2 coats of Hammerite Smooth Black.
Back to the RHS vent box. I removed it and slotted the fixing holes both front and back so that I could move the vent upwards. I refitted it and tried the flap again to check the position. I repeated these operations several; times until I was satisfied with the fit.
