Disco Tray back build

33 max inch tall skinny tyres you need full lock.

I've spent this afternoon playing with the jtv tractor rewiring it.

This morning I towed next door to the garage on a bar.

Mark trials vehicle is a lot different to what you have built. Light weight motor, skinny no winches or extra weight etc was john and Simon playing in their newish ccv motor?

I only have 9.00 x 31, but there on stock aloys with no spacers which rub ALOT on the radius arms.

I'm almost tempted to get a lil 88" with some small mud tyres and have fun with that.

Not sure if John and Si were there.. I'm crap with names

Oh and on another note, I was driving in the wooded area and had a branch flick up between the chassis and gearbox and dent the floor up a decent amount!
Ill try get a pic later.

It was a bit off putting to say the least!

Good job it wasn't the sump!

Had a branch come up and rip the wires off my coil once

Engine stopped dead of course

Took ages to find it when all covered in mud, plus, didn't exactly think of it so wasn't looking for that kind of problem!

Bro had a 3 inch tree flick up in water and come through the floor into the passenger seat

Next event it had 8mm floor not worth taking the risk

Yea.. since that I've been thinking about adding some protection to the floor.
I'm unsure about what material to use, would Kevlar hold up against a branch.. I assume it would?
My concern is to make it strong it would add a fair bit of weight traditionally.

Disco floor ain't as bad as fender

We've got steel floor, steel plate on seat base

Also I have 2mm stainless sheet for bucket seat mounting so feeling pretty safe

But yes it is a consideration often overlooked

Took a run down to the local scap metal recyclers to A find some phosphor bronze and B get the vehicle weighed.

I got a big lump of phosphor bronze for a decent price (much better than ebay!)
I'm going to make a couple bush pads for the diff pegs which will go in these D2 diffs.
(should have some spare if anyone's interested)

On to the weights, I notice the front end is a bit lower than the back so I might see about getting some different springs for the front.
Knowing the weights I can work out how much more the front end weighs compared to the back and also work out what spring rate I need to aim for.

The total is about 1850 kg once you remove me and the tools I have in the back.
Each corner is..
OSF = 600KG
NSF = 520KG
OSF = 440KG
NSR = 400KG

I need to work out the weights with the tools and I removed yet.

where did the phosphor bronze come from?

ie, what was it used for before?

apparently it is criminally difficult to machine!

why you say that

Because I thought it was a pretty rare metal, ie not the sort of thing your local scrap dealer would have lying about in large chunks

But if he did, what was it? Like, did mark buy and old part off a machine or tool or something? Or was it just a random chunk if offcut?

And I've been told it's like the hardest thing ever to machine, so be warned!

No idea what it was from, its a section that had been devided up from a huuuge bit of plate.

I've read briefly its easy to machine, but that may be wrong. We shall see!

Just use carbide tooling. It is a very good metal alloy.

A search will give you some good info, Used in marine industry, power plants, and where,high corrision, high strength is needed for non magnetic fasteners, and is easy worked to thin pieces and retain high strength

I got enough to make 12 buttons or 6 diffs worth for £11 delivered

Thats good, all i could find on ebay was about 50mm lengths for about £15

This bit I got was £13 and is about about 8" by 6"

Mark are you goog to turn the diff centre down s Ashcroft do or have the button half off half on the crownwheel

I hadn't got that that part yet, but ill try turning it if I can fit it in the lathe.

I'll have a gander to see how much will be hanging over the CW, if its only a tad ill not bother turning it.

I wasn't aware that the diff flange needed turning down?
