Armour Dreams

Talk about high's and lows, this last week has been full of them, it's strange how stressed I can get over my baby.

I now have 6 springs cut and drilled and assembled. I was waiting for the other 4 to be delivered, which wasn't due until Monday, today, so I decided to get on with other things and blow me they appeared on Thursday evening. By then I was in the middle of getting 4 suspension arms and wheels on so they will have to wait.

The springs have to have 3 drilling operations on each leaf, that's 390 holes, if I only have 13 leaves per spring and the steel is spring steel, so it's tough. Slow speed and loads of coolant. Each spring has a keeper plate with an M8 tapped hole in and a 22mm clearance hole for the main M20 fixing bolt. Then, for each spring set of 13 leaves, each arm requires 4off 80mm x 10mm flat steel packing plates and 3off 3mm x 80mmpacking plates, all drilled with a 22mm clearance hole. As you can tell I have been drilling a lot of holes.

First I drilled through with a 10mm HSS/Carbide drill and the opened it up to 22mm with a re-sharpened masonry drill.

On Friday and Saturday I managed to get 4 swing arms in place and I put 4 wheels on so that we could manoeuvre the chassis under the overhead gantry.

I have to say that although there's a lot of weight yet to be added, I was please with how it all sat. The reason for moving it under the gantry, was so that I could fit the steering box and start on the drive train and here's the low point. We tried the steering box, which I knew would be a tight fit but on Saturday I was convinced I was going to have to explore another option. If there was the slightest chance of using the box the front left swinging arm housing was going to need re-engineering. It's funny when you are tired, things seem so insurmountable. By this morning I had the answer and out came the plasma cutter.

After all my worrying, I have still got some room to play with, when I have slept on it and decided what to do. All I have to do now, is rebuild the swinging arm inner bearing housing. And what difference did the extra 400kg make to the suspension...….. very little.

Evening All,

I have at last finished drilling the springs and I now have 10 complete springs and loads of spring steel left over, so if I need to increase the number of leaves I can. The last 4 springs that I assembled, I used 14 leaves instead of the 13 in the other 6 springs.

The engine and gearbox are in place and the mountings all welded in. The exhaust manifold outlets had to be cut off, turned 180degrees, the angle adjusted and welded bock into place. Sorry but I forgot to take any before pictures. They need a little bit of tidying but I will do that once I have made the exhausts.
