How much would a machine shop charge to machine splines on a the average. I am trying to deciede how to lengthen my cv's. I am stuck between machining new shafts or cutting and welding the original shafts. Thanks, Brady

Re: "How much would a machine shop charge to machine splines on a the average"
All depends on the type of spline. Most spline/gear shops do not like to cut material that is harder than Rc 38. There are some shops that will cut harder material but it takes a carbide hobb so cutting or extending an existing heat treated spline might be expensive and tough to do. Also, you need to see if the shop already has a cutter that will do your specific spline. If not, the cutters are expensive and can run upwards of $800 and they'll want you to pay for it. If I were you I would make new ones and call Gearhardt Gear in Hollywood or Gear Design in Rancho Cucamonga. Either one could give you a quote on machining your splines.

Cutting & welding is not an option. Torsion bars (= halfshafts) & welds do not get along very well. It's just like trying to weld a leaf spring. It'll stick, but it won't take much loading b4 it fails.

How about and intermediate shaft the end pieces slip into with like 2 or more keyways per side, plus they would be the first to go, and easy to fix.

i thought the same thing, but there are some ways to safely weld the axles. A lot of the high power honda guys are using welded axles now, and while they do eventually break, they last a good bit longer than stock ones...

geoff- You should try and find out what special things the Honda guys are doing to make there welds hold up. Thanks

we were using axles from this guy:
www.driveshaftshop.com
his name is frank rehak, his site sucks *miserably* but he really does know his stuff when it comes to shafts. I was at SEMA with him (we shared a booth, shhh) two years ago and he knew his stuff unbelieveably well.
I noticed he is no longer welding the shafts, he now uses 4340 shafts, that too can be welded. Just give them a call, theyre good guys, tho they are a bit far away. if nothing else, get some advice.
