it is a self fullfilling prophecy. 
the more wear on the splines, the more slop in the joint
the more slop in the joint the faster the wear on the splines.

every time you shift or roll on/off throttle causes loose splines to crash against each other.  it is not a linear failure curve, the more wear, the faster it goes south.

bricks with new shaft and fd splines are SOOOOO smooth.  it is incredible how much of a difference this makes in the ride.

It seems at least half of the width of the teeth has been eroded in 1000 miles. Getting more than another thousand miles out of that shaft would be good luck.

Just curious, is the replaced spline some sort of after market thing,  do you know what grade of cheese it is.

Joy! Found a newer FD with great splines of only 35,000 miles on them, also, a free set of splines are being sent to me. I may harden and temper them before welding, perhaps?

I would think thar you need to harden them after welding.  Did you get any heat treating instructions with the spines?

No instructions, as Motobins just get a batch of them, then sell them on.

Apparently they also mate them to driveshafts, or contract with somebody else to do that.

I posted that information for the benefit of others who might not have gotten that impression from what you wrote. Anyway, it seems as though they would have information about the process.

See if Motobins can tell you the steel grade.  With that information any competent welder can harden the splines.

You need to check the hardness. Type in "How to check the hardness of steel". Do a few checks on the outside one near the weld one near the end and one on the teeth. Or go to your local friendly engineering shop with a bottle of suitable beverage and ask them to check it.

Looked on the YouTube about checking hardness. The ‘ball bearing’ drop looks like a way for me to check, in my own garage.
