Here we are again. The instructions in the kit are exploded diagrams of an indifferent quality.They show the brakes fitted to the outer frames as on the prototype.

 

But this will make getting the wheeled chassis almost impossible to get in and out. So I decide to fit to the inner ones. First problem was making out the hangers especially as the front one is off the frames, this then leads to a bit of butchery to the outer frame set up. Then there is the opperating shaft and vac cylinders etc, which need to be fitted to the outer frames, which leads on to there needs to be a detachable link between the brakes and the operating linkage.

Well there is a cast lever missing from the casting, that fits on the operating shaft, so with having to make a new pair this is where the split will be.

As you see here I have added tubes for the brake hangers, this is as the brakes have a cast on spiggot, which will make them easily removeable, you will see when I actually get that far. You can also see the hacked abouy front spacer to allow room for the front brakes.

To check the fit as I go it looks like I have to almost build the outer frames and footplate as such along with the running chassis, this is partly because of the brakes, but also the mounting points. There is a guard aswell that fits to the outer frame, but is located in relation to the front step, which rely on the footplate. I am sure other bits will also need to both parts built.

Some alignment issues.

I also think I need to assemble the basic cab and bonnet units to the relationship right between the outer frames, footplate and the cab and bonnet. This is as it is there are no slots or tabs for alignment. Not a problem just a bit more like scratch building.

Prior to assembling the footplate to the frames I tried some parts to get an idea of fit etc. The cab and footplate boxes as you can see are just folded. Once the frames and plate where joined I rechecked. There are some adjustments but not as much as I first thought.

All I wanted was to fit the brakes to the chassis, paint it black and the get on with the body.

I admire your foresight Pete and how you seem to spot the forthcoming problems instead of just blindly following the instructions.

How did you go about forming those curves on the bonnet edges so evenly?

Thanks.

Sometimes I see the problems other times they just turn up and slap me on the face.

I rolled the centre section in my rolling bars and the tight corners between a bar and a suitable ron in the vice. But looking at it the top radius is wrong I followed the front and rear formers, which I think is too flat. I will see if it can be altered without dismantling it, if not it is a start again job.
