You know I am interested. Looks outstanding!
Driveshaft Hoop?
- Thread starter HaroldD
- Start date
PART DEUX... 
After speaking with the tech inspector, he indicated that I would need a second hoop for the front shorty shaft. I personally disagree, because the shaft geometry is such that it would be tough to get it to dig into the ground with the carrier bearing there, but he's the inspector, so I duly agree!!! :argh:
So, to get a hoop around the front 25% of the front shaft is a little more interesting than the back since there isn't anything really close that I'd trust to hold it. Here's what I came up with - remove the carrier bearing frame adapter, replace it with 1/4" plate, weld a 2x1x.0125 tube to it, weld that to the same 3x 3/16 flat that I used for the rear hoop.
Sounds easy, but that carrier bearing adapter is used to tilt the carrier bearing so it operates in the correct plane - fine, I shimmed my plate. Also, the hole placement is pretty critical to get everything lined up just so.
I'm not as satisfied with the front as I am the back, so I'll play with some other ideas perhaps down the road to see if I like another solution better, but this will get me past tech. :burnout: :burnout: :burnout:
For those that wanted to purchase the rear hoop, let me see what I come up with for the front to see if I like this idea the best or not, and then I'll put a package together and post it in for sale. Likely a month or so as I'm out of spare time. Thanks for the interest and vote of confidence! :rock:

HaroldD said:Well, after searching and not finding anything that was a bolt in, I fabbed one up yesterday. I used 3" x 3/16" steel. The most restrictive racing spec I could find was 2" x 1/4" and this exceeds that from a cross-section perspective, and, most importantly, I had just enough in my scrap pile to do one! :rock:
These pics were taken with the rear axle drooped - I left more room for over-extension. I designed it to use existing holes in the crossmember.
Since I'm visual and call :needpics: as much as anyone, here they are... Not powder coat here, just some 1200 deg paint, but but I'm all about function! And this is one item I hope to never use...

That front drive shaft setup will not work for those of us with a 2/4 drop. The center support bearing is bolted to a shim that fits inside the slot of the cross member. Adding the front piece would change the pinion angle and create that dreaded vibration.

Cool, thanks for the info. There's a shot at going across the frame rails or off of the back of the trans too. Back of the trans would be good as it could accomodate wherever your driveshaft goes.
