I snaped a 35 spline strange axle many years ago, it wasent any fun,but the runner up the next week was a nice way to pay for the new axles.and recently married, my wife (first one)thought hmm we can quit our jobs and make a living drag racing and winning every weekend. now why didnt I think of that??? although the car did pay for it's self a few times over.wish I still had it now.(but extreamly gladd that wife is gone long ago)

[nsracing]

Tuckey, you got rid of the car and wife? I would have at least kept the car. Mine paid for herself many time over.

[mark tucker]

got rid of car many years after the wife was long gone to pay for the all new car..... that was 20 years ago and the all new car is still all new and not finished and a pile of $$$$$$$$$$ into it.life sort of got in the way.it's about time for that car to go.

sbeetle--yeah, it's before Gary messed with Type 1's much. He sold me someone's super diff with his tapered ring mod. That was way back in the late 80's if my memory serves me. I'm still racing with it sucessfully except for that annoying spider gear failure--which I'm afraid is going to put shrapnel between the ring & pinion--then there goes the entire transaxle to Volkswagen Racing Heaven

bugguy--that is MOST helpful information !!! Thanks so much for that idea...now for the questions: MAP...same thing as oxy-acetene torch? What tempering did it accomplish? Case-hardening? Would quencing in oil be better? Wouldn't case-hardening make the spider more brittle and shatter easily ?

Tom K--I've gotten away with using carefully radiusedType 1 CV's with chromoly cages for two decades of pure draggin' ! I'm cutting 12.5 in the quarter with a normally-aspirated 2287 that has all the bells and whistles. I get almost two race seasons out of them until eventually one cage lets go destroying the CV--which is a small price to pay since Type 1 CV's with chromeoly cages are cheap. I am using a shock-dampner on the clutch throwout to minimize "shock-engagement" with no clutch wear problems (adjusted correctly, of course). I'm hedging my bets that getting that kind of life drag racing with Type 1 CVs has alot to do with a ingenuis axle mod I came up with years ago, when I realized the outboard thrust to the aftermarket axle (shoulderless) leaving the line was jamming the cages to their end of their axial outboard play.... and then KAPLOOIE ! What I did was install a modified urethane "bumper" at the outboard end of the axles (in the stub axle cup) that keeps the axle thrust from jamming the cages to the end of their axial play.

Mark--race cars are like wimmen...both need LOTS of tweaking, so you're screwed at either end (pun intended--ha)

[Alpha_Maverick]

yeah, but cars don't make you sleep on the couch if you push the wrong button.

da heck they don't !! One wrong button on your race car and you'll be confined to the couch unable to move after the crash.

He's probably using a map/air torch, just like you would solder a pipe with but the MAP gas burns just a liittle hotter. A dull red is probably going to TEMPER the steel. Tempering reduces hardness a little but gives you more toughness(no cracks) For tempering want to heat nice and even and then let it cool slowly.

[michla]

I would imagine an oxy-acetelene torch could accomplish the same thing handled right

[modok]

Yeah, just gotta be careful not to overheat the edges of the teeth! Maybe a big rosebud tip? old BBQ grill?

[michla]

old BBQ grill ???? seriously ????

[modok]

It's more modern than building a fire, but you could do that too. Roast em like marshmallows

[michla]

so like, how about your common propane torch? I wouldn't think that'd get them hot enough

[modok]

A common propane torch's flame is some 1500-2000 degrees, so it would DO it but you'd need a torch big enough so it isn't cooling off faster than you are heating it. acytalene/oxy is more in the range of 5000 degree flame at the inner flame, hot enough that it can be TOO hot for some things. There is also a propane/oxy torch that is more in the middle is used for brazing and working with aluminum

[michla]

interesting.....
so is the propane/oxy torch commonly available in your hardware stores??

[modok]

No, can't even buy the flamethrowers anymore.

[michla]

So like where do you get propane/oxy torch setup? I've never heard of that.

[modok]

An acytalene setup can be converted to propane, all you need a the regulator for the propane bottle
The companies that make the torches and welding stuff probably sell all you would need

[michla]

Well, given all the used oxy/acetene setups out there alot more reasonable, I'll probably go for that. It's past time to get me some---my MIG and ARC welders aside !
Thanks for all your input.
