DIY ATB diff?

[ben_p]

Can you weld the diff in a 172? To give 50/50 torque ?

Reading recent threads it seems that the qualif diffs are only 50/50 ? so I could save a grand and just weld the diff and get the same effect?

iirc yeah, they did it on blue peter

 

[ben_p]

haha

Welding a diff surely would just give a solid axle?

Not a good idea and nothing like an ATB.

 

[Waitey]

lol no

 

[drhowser]

it would be ok in a straight line.........

you can do it if it welded in the right spots

Think about what you are suggesting.

 

[MarkCup]

I'd like to watch you park after doing that.

How?

 

[Tom]

I'd like to watch you park after doing that.

Or, Drive round corners/ in a straight line.
Id imagine tyre life would be 15-20 min.

STUPID IDEA!

Show me where to weld?

 

[ben_p]

i dont know where to weld it! I've seen it on a few fourms!


IT WAS ONLY AN IDEA YOU BANDITS!

Top One ^^^

good luck removing the diff from the box!

you'd weld the planetary gears solid, so they dont rotate, and hence divide torque equally through the crown wheel.

It isnt as a stupid idea as peoiple are making out IF your only going to drag/strip race....its a common practice, also on the drifting scene.

As people have pointed out, turning would be difficult, though not impossible, you'd just get alot of scrub and a crap turning circle!!

I know, and we say its a crap one that will never work like an ATB, unless you can prove otherwise.



The technic Stan says gives you a solid axle, and only practical for 1/4 mile stuff not the road or the track.

well you could have just said "no, it wont work"... lol

 

[stan*]

He never asked if it would work like an ATB, he asked if it would achieve 50/50 torque split...which it will. However it wont have the same effect, as its a permanant fixture which isnt sensative to wheel slip.

There we are, thats his question answered, so no need for any more bitching?

 

[TheJesus]

well now that's cleared up, how do you go about welding the diff? Chewing gum goes quite hard?

 

[stan*]

chewing gum works, paper clips and parcel tape are also a winner!

 

[TheJesus]

double or single sided though Craig!? lol

 

[stan*]

single, always single!
