Well wiki schooled me up. Superstructure was actually steel. Urban myth about the mag ally.

Maybe I should change my information source from Urban Myth to Wicki then - lesser of two evils! - I think I said aluminium alloy though - or did I?

When you guy were going on about it I thought you meant a landrover catching fire.

The M113 APCs we used to have were made of Aluminium Alloy. supposedly the RPG's used to go straight through one side and out the other with out the shaped copper lance causing to much issues as the armour was that soft.
Only issue was I think the bullets used to go through them like butter as well.

Well as long as you aren't foolish enough to be standing in the way at least you wouldn't get blown up.

I found this

They later used Cyclone mesh as armour augmentation against RPGS

I think the original story was the high explosive went through them witout detonating but I guess the RPG worked as intended so thus the need for the mesh gates/fences

The armored vehicles themselves provided protection against the enemy's small arms and automatic weapons, but the men added a new device to protect the vehicles against the armor-piercing B40 rocket-propelled grenade (RPG). It was called the RPG screen. Nothing more than a section of "cyclone" fence, it caused a shaped charge warhead to detonate before it hit the vehicle. Each crew set up a section of fence in front of its position, and the command element in the center established a second screen around its vehicles. This simple expedient saved many vehicles and bunker positions.

Gee they even developed it further


SO if the Russians invade we will all know to armour our Prados with cyclone gates ( I have about 20 of them so I am all sweet)

The four stroke boys could fit that inside the crankcases - might save the track from becoming saturated in oil every time they blow up!

D2, draged out of the storage cow shed, haven't run it for five years. Fired right up. Yeah Right, took nearly half a day, pull to carb to bits, pull the mag to bits, clean them both then she fired straight up. Had to drive it for a few miles across the farm next door, I have to admit it was good fun! Gave it a wash, the birds had turned it nearly white. Grand kids and I had a great time ripping around the back yard.

That's Beautiful.
Show all those unfamiliar with the old D2 how these wee gems are started (ie the starter motor system)
A guy I know has the full set of Cats up to D8

Most of the classes in road racing now require the bikes to run Diapers (bellypan catch tanks) yes even the 2ts, I think the four stokes incontinence is due to all their additional parts they have stuffed in there already.

Is there any best practise to define the shrinking factor for aluminium casting?

Cylinder with fins and 60mm bore

Neil can do the shrinkage factor as it varies plus I can't remember but it was something like 1.5 to 2 %. But remember you need to allow a Machining allowance for the finished surfaces like the bore as well.
From memory by internal bore is 49mm vs a finished size of 54mm to allow for casting finish defects and machining plus shrinkage.

the starter motor system

I had to repair one once. The main engine had thrown a rod through the starter motor block and it was in about 5 pieces.

Got everything for the main engine, but a new starter block couldn't be had for any money. Braized it up, line bored the mains and bores and filled it with a new crank, rods and pistons. Probably still going.

Just remembered something weird about that job: I had to modify the mag drive, it was 180 deg out. Had me fucked then and it's got me fucked now.

Did you swap the plug leads LOL
I have always loved the D2's since I was a kid.

Funny thing, the ignition wires emerging from the mag are opposite ie left hand wire goes to right hand cylinder? Just noticed that today when I had the mag in bits. They are not fun to work on. Any way once we got spark and fuel it fired right up, who would have thought, I was getting sick of pulling to rope. Actualy the ignition problem turned out to be corrosion on the output lug to the off switch, corrosion was shorting the ignition to earth, cleaned it up and the sparks came back, lucky as I had run out of ideas by then.

Approx 1.5% for CC601, although it depends on the alloy, LM 13 would be less.
If I'm making a 50mm bore I'll cast it at 45 / 46 mm

Can't even remember if it was 180 deg... Fuck it was 40 years ago, but no possible configuration of parts on that bloody thing resulted in correct timing.

The water jacket core box for the zurg cylinder, I will probably copy cast this core box into aluminium so I can use shell core sand ( hot set sand )
