DIY earth mod,....being as there is no projects forum ;-p
Questions at the end 
Find a chunk of aluminum

Mill it to required thickness my case 38mm wide (was meant to be 40
)

drill a hole in it and lathe to a 3degree pitch

I got a little carried away here
(clocked it up to ensure holes got drilled in middle of plate)

Setout the holes (all looked ok at this point
)

Drill and tap the holes

Grab camera again while drilling

Cut it to length now hole distance has been decided upon

TADAAAAA

different angle

Fit and finish (well almost)

A
few modifications to Prototype No 2 will be required
spacing of holes, left to right was near perfect (see how neat the ringlet sits next to the next one).
However I balsed up the front to back measurement, only allowing 12.66mm instead of 15mm. Doh !
Oh and the reason I have only done three conections is......
6 holes...so bought 6 gold plated ringlets....DOH ! the cable has 2 ends
Andy
At the moment the ally is nice and bright but will tarnish. what do I do about corrosion protection ?
(sprayed with WD-40 as temp measure
)
OK, could I have it anodised, will this reduce it's conductivity ?

Looks great. Puts my tatty earth mod to shame.
Someone round here a couple of weeks ago said that he could do gold plating
I can't think of a better use. You've gone to the trouble of this much overkill, so why not IMPROVE its conductivity and protect it from corrosion

How about making a shed load and selling them for £2 each - I'd have one 
Seriously if you do decide to sell some I'd be interested.
In terms of corrosion why not coat it in the stuff which is normally on the battery terminals ?

Naughty-naughty for holding the work in a 4-jaw like that (pic.4) Should have used a faceplate? (The photo is 90* out!) Engineering critisms over, it turned out ok! As I did a 7-point earth mod ages ago it would be good to finish it off with something like that.

nice neat job
but i hate to put a dampener on things,
i am an electrician by trade,,copper and ally dont mix to well when conducted with electicity,they corrode,quite badly infact,,
cant you get hold of any copper block to do the same job?????to stop it from corroding smear with coppa slip???
just an idea.
on my new car the earth mod i used this time was a large crimp(lug)with 6 of the wires all going into the same large hole and then i crimped it .
all the best mate

MRK,
£££££ from car hi-fi dealer.
Those six
GOLD
connectors and 24m of 8swg cable cost £24..something (£20 cash as I know them
)
Those that want one...
Are you looking for a "package" with all the cable and connectors
Or just the earth Block ???
Would need to find a cheaper source for the connectors and cable to make it competative I think ?? any ideas?
Also want to mod the block so that all cables tranfer out on the same side of the block, would need to re-position holes.
Prototype No 2 on it's way shortly

Both.. Kit price would be handy or at least the componant you used so I could try and source some.. Have a friend that works in the car audio trade.. I was looking for a neat solution to the battery connection....

From: Leeds - It was 562.4bhp@28psi on Optimax, How much closer to 600 with race fuel and a bigger turbo?
Andy, Looks Nice...
You get better tools and better scrap at work than I get at home..
Most car audio terminals are Brass and not gold.. (im not on about you andy)
Alu. is a good conductor and most cables for power industry.. Ie 11kv cables are alu.. not copper.. (probably down to cost though!)
Still Nice.. but not my cup of tea..
I would still go for the same but on the chassis leg.. as I would rather have it look std..

<scratches head>
front intake conversion.....Front mounted house..I mean intercooler...water injection..Nos...Turbo....the list goes on.
I think it's a bit late to keep her looking standard David
All the best

How many earth points do you all want ?
Is seven enough?
1. Alternator.
2. Inlet manifold.
3. Right strut turret.
4. Left strut turret.
5. ECU support bracket.
6. Left front chassis Leg.
7. Right front chassis leg.
don't wan't to have to make them a third time
Got my eye on a full length of aluminum bar, it's just asking to be hacked up
Andy
edit as I can't count

nope, just a bit stuck in the evenings at the mo, waiting for parts to come in for a car job I have in the workshop. (snapped cam belt) doing this as a favour if he makes me a tool for making the degreed hole in this earth block everyone is interested in.
Tis a bit labour intensive, drilling it, then setting it up in the lathe, to put the degree on it..
Andy
P.s I hate friggin timing up diesel engines
p.p.s if you would like to have a go at putting something together of the RR day @ Powerstation that would be great.
could combine turboteeths footage too....
up to you, I'll bring you the original tape at the star meet in Feb if you like?

turboteeth's footage is actually my footage
he wanted to be cameraman that day and i couldn't be arsed to film 
yeah bring the tape down to the meet and i'll have a play...
might be a good time to test some ~ahem~ audio rendering

Just because I can afford an Impreza and have enough disposable income to buy mods, doesn't mean I like throwing money away. Why pay £100+ for someone else's kit when you can do your own for a fraction of the cost. What's the point of lining someone else's pockets
If I had the tools and ability, I'd make up an ally block myself.
No offence, but it gets right on my nipple ends when folk say that. I can just here my Dealer say, "well if he can afford one of our cars, he can afford to pay more for parts and servicing".
[/rant mode off]
I was always told too spend your money wisely. The £90+ I saved will go nicely to my summer hols
Fuzz,
Top work m8. Lets us know the final costs and when you're ready to start making batches of these. I fancy one of the ally blocks myself
Stefan
P.S. I've already got all the cables and connectors on my car already, so it's just the block I need to tidy up the battery connection.
