Thanks again for those kind thoughts Mark and Roy! Blushing
Coming along well at the moment, just been doing some repainting on the front brakes air scoops - the reasons why will become clear when I show the work on the rear brakes air scoops!BigGrin
Have also made the computer use a little easier too. The diary is put together on my old Windows XP computer to be able to run the Corel Printhouse program and then uploaded on the Windows 10 one as XP won't log on to Modelspace (that started about a year or more ago). Until now I've had to put the '10' keyboard under the computer table and then slide the XP monitor onto the top of the '10' desktop case, followed by the XP keyboard ... now I've got a monitor switch box so both computers are able to use the same screen. Much less pulling and pushing, just got to get used to the old XP displaying on a totally different screen shape - almost square where the old monitor was widescreen - the 800x600 photo pages just look ....wrong!BigGrin I'm also getting another mouse too, swapping the one over between the two leads to unfortunate episodes of "why isn't the flaming thing working, it's plugged in right - oh, just not into the right computer!"Blushing

Anyhow, onwards!

Before carrying on with the brakes, it is first necessary to finally secure the gearbox assembly to the main engine block. Photo 1 is a last look through the inside of the gearbox with the two screws visible at the back, which were screwed into the holes in the engine rear. Once that is fixed firmly in place the plastic rear section which should go on now but was screwed on earlier in order to airbrush the whole unit in one go is replaced and screwed back down as shown in Photo 2, the yellow arrow indicates the screw position which marries up with the protruding tube seen in the previous shot. Photos 3 to 5 illustrate the rear brake discs coming together. The whole assembly is simply push fit. Photo 3 shows the two brake discs after their Humbrol Blue Grey Enamel Wash with the central axle. Photo 4 (which was taken before 3 but they fitted in to the spaces better this way) shows the two halves of the discs with the bottom right one still in its kit chrome finish to compare just how effective this wash is in turning chrome into steel! There was no skill or finesse needed here – a large soft paintbrush (a Revell size 6) was used to both mix the wash with white spirit to dilute it down and then to liberally ‘slop it all over’, all the work being done by the raised and sunken detail itself just pulling in the wash as shown here. After an overnight drying the halves of the discs were snapped together and then pushed onto the ends of the axle as seen in Photo 5. The black lines on the axle are where I scraped and filed off the flash lines – this is simply to ensure the axle turns smoothly in the gearbox channel, the whole axle is encased in the channel so repainting wasn’t required. The axle assembly is shown sitting in that channel in Photo 6 – not easy to take as the darned thing keeps falling out of it! To secure the axle in place, as seen in Photo 7, the first part of the rear suspension block is screwed into position, trapping the axle in the now circular channel (this part was also airbrushed at the same time as the gearbox!) The screw visible at the bottom engages into the hollow cylinder seen underneath the axle central ‘bulge’ in the previous photo.
Photo 8 is another screen shot from the kit instructions showing the rear brake connector pressed down into the semicircular hole in the top of the gearbox. As you can make out here, the kit version has two long spigots sticking out of the sides over which are slid the two white brake lines later on. At the front is a simple ‘stump’. As you will see later, in actual fact the kit has simplified those brake lines. On the actual car, just as Ruda did in his build (thank you Ruda) the brake lines are really a pair of copper pipes far thinner than the kit ones – some more scratch building again! Photo 9 shows the stages of the conversion (watch out for the ruddy thing pinging off your workbench if you go down this route – its so slippery to hold in both fingers and tweezers!) At the top, the side spigots have been cut off back to the moulded nut and a tiny hole drilled into each. The front stump is also removed and a 1mm hole drilled into that part, the black square in the top pic is just the flash removal showing the black plastic showing through. The centre pic shows the piece after a re-paint with Vallejo Air Chrome for the body, Vallejo Brass for the nuts and black for the top nut. Once dry the whole thing got the blue grey wash as usual before it was push fitted into the gearbox as seen in the bottom pic.
Before plumbing in the brake connector, I first needed to do it for the clutch return. As you may remember, I’d previously drilled a 1mm hole into the underside of the front nut on the clutch return and Photo 10 shows that hole now fitted up with a short length of the 1mm diameter copper plated aluminium wire. This runs down to the top of the engine and then goes under the ECU. The fact that it isn’t actually attached to anything under there doesn’t matter as nothing can be seen underneath anyway!Cool The illusion however, as shown in Photo 11 is that it is running out from the other side of the ECU and down into the firewall (brown or white tube I have no idea!)
In the following instalment the brake connector gets its main pipework and the suspension linkage system begins (and gets in the way a lot!)Cursing
Until then, Happy Modelling to you All!

Robin.

Hi Robin,

As usual , stunning work. I have started to regularly steer people to this build as a reference build that illustrates the potential of the kit, fully realized.

Keep it going!

Cheers,

Mark
