I'm designing without having the parts I need in front of me. They may be here by the end of the
week.....but....could anyone tell me if the 5/8" 36 spline on a BMI steering shaft stops at the
snap ring grove and if it does, is the splinned section 3/4" long? I assume it is because
the flange (which I do have here) is 3/4" long?

You surprised me on this one.
With all the equipment and skills you have........you ordered a BMI go kart shaft??eye rolling smiley
I to got a short set from them once because it was on sale for $4.99 and it gave me
two 5/8" 36 spline U joints and one splined end.
But I assume the shaft they see is "solid" thus weighs too much.
I used a nice piece of Chrome Moly 3/4" tube and put the solid splined shaft piece in the end
drilled, pinned and welded it.
Much lighter and worked with top and bottom pillows (two different styles).
More work.......but that is what having the equipment is all about.
Get back to work!

Denny,

I got mine from MFG Supply but it has a similar part number as the BMI one "AZ-1868...". I am guessing both are from or copied from Azuza.

I will check when I get home from work.

The splined section is 3/4" long and the threaded section at the end is 5/8".
No snap ring groove. And Brian's right. Its heavy!
I'd like to cut out all but the very ends and replace it with tube.

No, I wouldn't want you to be to surprised Brian. I needed the splines. External 36 tooth splines
are just to labor intensive to cut in the mill, and the internal splines require a very expensive broach.
And I've spent most all of the afternoon with the CAD, drawing up the side steering support and
ordering bushings for the pitman shaft. I've had to cut out and move a cross member and
re-shape the side body supports to better fit the hood side panels.
And.....I'm ahead/with ya on the steering shaft and pitman shaft. Got some nice
3/4" .065" wall 4130 left over from when I built the airplanes. That's gonna get
used to replace the solid Ross steering shaft and the pitman shaft. I've got
quite a bit of CMS left in stock, different sizes 5/8, 3/4, 7/8 and 1 inch,
most in .035" wall.
My shafts are scheduled for delivery tomorrow Vince, so don't bother if it's any hassle.
I've drawn up the splinned end at 3/4" with a snap ring grove where the grooves end.
the 1/2 thread is of no concern.

Perfect Vince, that's exactly the way I've got it drawn up. Now that you've confirmed my dimensions
I can get going fabing up the parts I need in the morning. My splines probably won't be dropped off
till supper time, but I'll have everything ready to weld up Friday morning.
Thanks for taking the time to post that, I do appreciate it.
