workshop is now built and the car is back home - still got alot of interior stuff to fit into the workshop, and alot of stuff in storage, but we are getting some progress



SO as a coming home sort of present I bought her one of these







Not sure if its what I really wanted, but after seeing Andy Gallacher launching his focus with one of these in, maybe its not a bad unit, alot bigger than a std item, but not as big as the 8.5".

Thats what ive just purchased along with a 3.9 9" rear, hope the front cope's should do with the weight of my car.

Im not a fan of R&D at all , mainly due to their customer service, seen many issues with the 6 speed box, but after watching AG launch a 700+hp car on slicks, can you really go wrong with that front diff is what I decided ? i dont know - I hope im right, though im not brutal with transmission.

What did you give for yours if you dont mind me asking ?pm me if you like.

markk

iTrader: (2)

ok, been looking at this ar still, and as slow as its going, im still plodding along with it, im managing to get about 3 hours a month or so on it lol !

I sold the R&D front, as basically it would just be sat in my workshop for ages doing nothing, and decided on another front diff avenue, I had seen it done on a large hp rallycross car and thought hmmmm.

If a std 4x4 rear diff will take + 400hp (in 4wd trim) then it would be more than fine if it would work as a front diff.

here is the progress.....











slightly wider than an 8.5" from memory, and will have to make a new front crossmember bit looks like it will fit really nicely.

i like what u are doing with my diff pall. looks good

markk

iTrader: (2)

it looks like a viable option and thanks to you it seams to be measuring up well

At least one thing, you will know when you get your diff back, that its had its oil removed, cleaned up inside and inspected, its in very good condition, and will have all new oil in it!
The least i can do for the loan.

Does it matter that the diff will be in affect running in reverse, will it put strain/thrust on bearings etc that was not designed to do so?

markk

iTrader: (2)

bearings will not be a concern at all, originally, my concern was the fact that the pinion will be turning the crownwheel on the wrong side, after a lot of research into motorpsort diffs, and people who have used rear diffs in the front, my conclusion was pretty simple, I have a car that in full spec will probably do no more than 2000 miles a year (pretty much the same as most peoples cosworths lol)

So, if the diff wears out, I have to spend another Ł100 on another, bit of a no brainer really (as long as you keep the diffs standard and do not modify them).

but from the people I have spoken to, they come to no real harm.

maybe it running them backwards would not last as ford intended, but its nothing like the milage ford wanted from them e.g. +100,000 miles in its life, vs my 2000 a year for maybe 3/4 years.

done a tad more this week

Decided to make up my own brake bells rather than buy them, takes a lot longer, but, I enjoy making things myself.

might get them finished next week.

you get a great feeling by making stuff your self that othere's have to buy it's what set's you apart from the rest


Great Build

graham c

iTrader: (5)

but if you flip the diff round it runs the rite way? nice bells mark

markk

iTrader: (2)

runs backwards then graham, takes a lot of thinking about beleive me!

timotei1980

iTrader: (1)

yeah see what you mean, if you turn turn diff upside down (saw it on scrap heap challenge once i think). Would you have problem with breathers tho and would it sit to low.

Cilly-jey

Be good 2 c it when it's finished.

Lovely work

markk

iTrader: (2)

still plenty of finishing and final sizing, im no machinist what so ever, just enjoy making stuff !

carcollector

good job for a non machinist, i coudnt do that....

markk

ready for anodising

the other is on the lathe now, will make up the caliper brackets then send them all for anodising in one go.

markk

iTrader: (2)

The finished (apart from anodising that is) items





first time ive ever done angled taper turning - quite happy with it really, just need a powered section on the lathe for cutting the angles rather than by hand.

Stunning Lathe work

markk

iTrader: (2)

Thanks, but i wouldnt say stunning, ive seen and had some awsome machining done, all mine is some bits for my own car done on a lathe that was built in 1960.

The time it took me, well, I won't go into that, but manually measuring and cutting to 0.01 of a mm is very time consuming, the second one took me about a1/3rd of the time of the firat one as i thne had something to measure off.

Its all part of the enjoyment caliper mounts next on the milling machine

I think I should have got into machining as a career, i might have been good at it if someone could have taught me properly.

looking good fella , !!


who do you use for your anodising mate ?

markk

iTrader: (2)

No idea yet pal, never had any done.

Nice bit of turning there Mark

I bough myself a lathe last weekend but for now i have only gone with a mini lathe to see if its something i really get into,

It's a 7x12" so its just 20mm too small on the swing to turn a brake bell so a bit gutted but it was very cheap and came with 4 jaw chuck and tailstock chuck and centres etc but i have already almost double my costs with decent tools and the best bit by far is the quick change tool post. (not yet fitted in pic below)


I am currently just turning some more bladed anto roll bar drop links in stainless steel as you can turn ss on a mini if you take your time, but just as i was finishing the first one the tool dug in as i cut too deep and damaged to end of the droplink with the chuck teeth so was gutted but it takes practice and as you say, plenty of time and patience

Turned these out of a left over bit of 5/8th alloy hex the day i got it to see how easy things were to do




They have no purpose what so ever, i just wanted to turn something with my new toy

M K

iTrader: (9)

turned 2 drop links today but the fun will be drilling a hole through the fookers lol

ian sibbert

I have blue and gold on the go !!!

markk

iTrader: (2)

I'll be round to have them done

Can you remove old anodising then recolour them ? im using some old but good bells that are red, i like the blue colour

in fact I like that so much, im on the hunt for everything to anodise now !!!!!

ian sibbert

Mark,

You strip anodise off with a caustic bath, this strips and etches the ally, quick rinse, into the electro bath for an hour, rinse, dye for 15 mins then seal for 30 mins the hot pot....

Painting the workshop out at the min but the anodise setup is accessible....

Ian

markk

iTrader: (2)

Im on it !!

4 brake bells and two air inj bodies up to now then !

-beefy-

iTrader: (6)

ian can you anodise red fella ?

ian sibbert

Beef,

We have just got the dye, i'll do a sample and let you have a look...
