Title: Home built propshafts?
Post by: ferretjuggler on March 30, 2010, 04:30:14 PM: Anyone know how to?
Watched some program once, guy welded one using a lathe as a jig.
Not very user friendly to the lathe, but it worked.
Standard practice in India apparently, balencing done by trial and error, or not at all, depending on quality of local roads. :017:

Remember, in 5th gear it is spinning faster then the engine's crankshaft and it.s a heavy lump, so it really is a precision job. I have one that someone made for me, and it's never been 100% right.

Thats sounding more like it :003:
I'm confident I can fabricate/weld a prop 99% straight and true, balencing weights will cover up the 1% error.

nope, be serious dood :hysterical: but we was discussing some idea about one of the projects and u said i had to get some made if i went that route, so seemed sense to sort out who does before this gets lost in the mists of time

Should you try it? Do whatever you think your skills can muster.........

Post by: ferretjuggler on April 08, 2010, 09:42:12 PM: Thrown props usually caused by people who wont listen to sound engineering advice, and think they can force a prop to drive at a ridiculous angles with large quantities of torque/rpm.
Dressing the yokes with a grinder might improve clearance, but it wont stop the prop winding up and breaking at its weakest point :003:
What you might get away with on a little 'zuk wont work on a V8 CJ :greggmo:
