How much front driveshaft slip?

How did he take a spline shaft with a butt end designed to go inside 3" .o83 tube and make it work with 2.125 tube?

From the pics it looks like he may have cut the butt end down at the taper and just butt welded it to the tube? If so, this seems like a major compromise in strength.

See this I was I take offense. You seem to want to find problems with the shaft. First it was my pictures weren't detailed enough, then I have limiting straps, now they must have cut corners on the shaft and it isn't as strong as I think it is.

Asking questions and seeking clarification is one thing, making assumptions is another.

I have been busting my ass on this build for close to two years. I have not cut corners once. I research and research and research. If there is a more dependable or durable way of building something, that is the direction I go in.

I spent several hours talking to my driveline guy, told him exactly what I wanted and he delivered.

To answer your question, he put the slip in a lathe and machined it down until he could do a cold press on the tubing. It was not just a cut butt end welded on to the tube. He specifically wanted to size down as a cold press on a machined pilot and the .188 tubing would provide the strongest juncture.
 
I think that proves that you found a guy with a brain and skills! Good Deal!

This is the biggest part of the battle; finding someone who will listen and not just sell you cookie cutter stuff.
 
Machining down that end to put in the tubing size you need is also a super common practice
 
Another thing 2" .188 wall.

I doubt there is anything out there that fits that. Machining or adapting is just a fact of life when working with that

@4wheelinfury did he balance it?

yea, I am making another youtube video about it. First it was a cold press, then it was balanced on the machine using a runout gauge to identify high and low spots. Each of these was balanced with mallet and punch. Once runout was limited to several thousand's of an inch, the shaft was welded. Once it was welded runout was measured again and high spots were heat treated and cooled rapidly with water to shrink them. Finally the cv was hand ground and balanced on axial balance.

Bottom line, thing is as straight as an arrow.

Yeah, I know machining is common, but the design of that butt end didn't seem like it would allow that big of a diameter reduction.

@4wheelinfury I made an "if,then" comment. What is wrong with that? Never said your shaft was junk. I am trying to understand how this super awesome infallable driveshaft guy made your shaft. Point is that no one is perfect. Maybe he is right and maybe he isn't. Its sounding good for you so far. See what happens when I ask a question? You provide more detailed and relevant information.

I think you are being way too sensitive about this.

You could have just replied, "nope, he machined it down" and then it's a moot point.

I've already said I like your build . . .

If you can't tell, I am a details guy and "iron sharpens iron"

Nice. Lots of guys won't even try to balance a .188 wall shaft.

IMHO that's the biggest difference between driveshaft builders.

Some guys have no clue how to do it.
 
By the way, I can already see where this is headed. Just go ahead and insult me now for being an electrician and get it over with :haha:

I am trying to make amends here. Hopefully this made you laugh if you've been paying attention to some other threads.
 
yep lots of good info......

and I'll be sure to share my personal driveline requirements and shiny new things in the next 6 weeks :flipoff7:
 
I had done every cheap thing possible except limit my flex. I thought I had it figured out. Hadn't pulled my driveshaft apart in a while.

Got on a steep climb had to give it the beans to make it up the top lip and bam.

Seperated.

Very hard spot to recover from too.

After that I measured and then figured out how much the driveshaft moved due to axlewrap.

I wheeled several times with no new shiny things.

Now my new shiny thing hasn't seperated for the last 5 years
