Possible job making a 10" longer steering shaft. A couple questions please.
Have done that. Only in reverse, as I shortened a shaft to get more belly room at the wheel
Just keep the little ridge or bump out on the flange at the triangle end where the steering pinion gears mount indexed or in-line with the keyway at the taper end. If you look at your shaft you will see that ridge in line with the keyway.
Just cut the shaft in two, index correctly and weld 'er up.
How I would do it is take two shafts and part them in a lathe making one about 1½" longer than you need the total length to be. Since the shaft is about .750" in diameter, I would drill a 3/8" hole into the end of one, and then turn the other shaft down to about .320 (+/-) where the two shafts will socket together. I also would take the shaft with the hole drilled into the end, and bevel the entire end about 75° where you will not have a complete round weld. Then just clamp it and TIG weld it together.
I probably have left out a few details but that is the jest how I would do it. Probably other ways too, but the thing I like to see is a weld that goes at an angle so if it should fracture, the chances of you suddenly losing all steering is less.
Since I am 6'3", 240 lbs. I like the idea of shortening the steering shaft for more room behind the wheel. Of course any alteration in the length of the steering shaft will also have to include the same alteration to the throttle and spark levers. Jim Patrick

Add a ujoint or two while you're at it, and you can leave the stock lower bracket, and mount the steering wheel at optimum location.
AircraftSpruce.com has a nice 3/4" ujoint.
