What are you running for a driveshaft

[Flash68]

My 3" aluminum DS is rated for a critical speed of 9374 rpm and a torsional yield of 3633.75 pound-feet.

And yes I stayed at a Holiday Inn Express last night.

I was looking at that Raj. What exactly is accu-bond?

Yeah, but did you eat at Denny's?

Hey Ron -- from what I was told is that the aluminum matrix (Duralcan MMC aluminum) used in the Accu-bond drive shafts is not "weld friendly" but stronger than 6061. The guys at the shop swear by the Mark Williams stuff. Here is a quote from their site:

Accu-Bond driveshafts utilize the Patented (7,485,045), end fitting bonding process that much stronger than conventional welded shafts. The end fitting are produced from 7075 forgings 50% greater strength that conventional welded fittings. The result is a stronger and more accurate running shaft at a reduced cost compared to the Aluminum and Carbon Fiber shafts.

Just technical enough to make me try it...

I had Inland Empire build my drive shaft. It took them two tries and they still didn't get it right so I had a North County San Diego shop (Oceanside Driveline) fix it due to time constraints. I seem to recall this happening to Rupp once and they fixed it on their dollar, no hassles or anything. If I was local to them I wouldn't hesitate to have them build another drive shaft for me in the future. I want to think I just had bad luck.

What was the issue Matt? Just wondering? Length? Balance? Yoke?
