Drive Shaft Loop Help ????

[JDM55]

hay peoples looking for some advice

 

been stuffing round with my drive shaft loop trying to get it to fit ,

i ended up making 2 x 2.5 mm steel plates and drilled 4 holes in each,

then welded in some thick bolts, lined up the loop and drilled some holes thru

the floor ,bolted it in and swung my full body wieght on it ,its solid and doesnt move,

but I'm still not happy , i was going to weld some steel plates under the floor,

so it would go something like this :::

2.5mm steel plate with bolts

thru the floor

then thru another steel plate

and then thru the drive shaft loop ,

 

does this sound like over kill???????????????? or what i have be strong enuf?

like to see some pics of what others have done that would be helpful,my cars a ke55

 

any advice be great thanks guys

dude don't over do it. seriously its only there to 'catch' the tailshaft if it breaks thats it. it more about the positioning of it.

what you have is more than adequate.

That seems strong enough to me, I would be happy with that.

Have you seen The fast & furious where Brian is racing in the eclipse and the floor falls out?

 

That is you when the tail shaft breaks taking the floor with it :)

 

In short - yes it is over kill.

ok well thanks guys i guess ill leave it as it is , i just wanted to get a few options ,any one else want to throw there 2 bob in ? :)

Sorry I didn't realise this had an SR in it but I still would of went for 2 bolts with large washers, atleast you know it won't be moving anywhere.

tat looks like it would hold up a truck one :)

yeah been doing the sr conversion for a while now, yeah i was debating 2 or 4 ,i only ended up doing 4 because thats what the ends of the drive shaft loop had on it orignaly, i had to shorten it down to get it to fit and redrill, i may get 4 thick washers and lock washers ,hopefully that should be ok, i had spoken to an engineer about it,actualy an engineer that i had been using for a bit ,but this guy seriously had no idea ,he may have had the paper to say he was an engineer but some of the things he was making me do was just rediculous ,changing his mind after id done what he told me and bascily not making any sense at all,he wanted me to weld little brakets to the floor with bolts hanging off , i had made up the brakets that he wanted but on closer inspection i found these to be a terrible idea ,as the brakets were small and would just rip off the floor if anything realy went wrong,also the drive shaft loop wouldnt have even been touching the floor the way it is now, it would have hung down away from the floor about 8 mm only touching where the it bolted to the braket thingys ,make any sence??? and way i believe the surface area of the 2.5 mm plates is way stronger than having any bolts welded to the bottom of the floor and the loop actualy is hard up against the floor also, any way ive got rid of that guy as he was breaking my balls with his rediculousness and I'm using a differnt engineer now

haha yeah cheers mate i hope so ,just want it to pass engineers ,trying to do everything as strong as possible ,

still suprises me how long little things like this can take ,cheers for the advices by the way , after i sort this out looking at doing the fuel system .....

yeh it's overkill. 2 bolts per side would have been sufficient. I don't even know why he made you put a full loop in. Again, overkill. When I engineered my CA turbo poobird, I put a 25.4x 6.35mm strap across underneath with 4 half inch bolts, 2 each side.

 

It's not taking bugger all weight.

 

 

he may have had the paper to say he was an engineer but some of the things he was making me do was just rediculous

 

I know some engineers and there's plenty out there like that ....

I have seen chain bolted to the floor to stop run away shafts.

Thanks philbey kinda put my mind a ease about it, i just know how some engineers can be so anal about silly things like this,

well ill leave it how it is for the moment and fingers crossed i wont have dramas with it,theyll probably pick everything else haha

,it kinda takes the fun outa building when you have to follow all these rules and regulations ,can't do this can't do that ,ohh don't do that!

not that I'm being dodgey at all ,going for the best result i can get ,but yeah ahh well onto the next step!!! maybe in like a few years we will find out if the loop was ok haha,god hope it doesnt take that long , i wanta driveeeeee :P
