With the conversion of my VooDoo Wazoo to Campagnolo 10 componentry, I have run into a few snags and am seeking guidance to for the following problems:
1. Are there smaller Record-compatible large chainrings (in the 46-48 range)?
2. With the small chainring running precariously close to the driveside chainstay, which bottom bracket size is adviseable?
3. The clamp-on front derailleur is coming off of a Litespeed Palmares which required a 35 mm clamp size. The Wazoo's seat tube is much smaller in diameter and none of my previously used reducers will do. Suggestions?
Thanks in advance for your help.

I have not seen Campy rings in smaller sizes (they may make them tho),others do for sure.TA,Sugino,and others make 135 BCD rings.Note that the smallest inner ring you can use is a 39.

If you have crankarm clearance on the left non-drive side,you can put a spacer on the driveside between the BB shell and the lock ring.If you don't have have room to shift right,you will need a BB spindle a few mm's wider.It should also be Campy specific,which is different from Shimano specific.

The clamp on a Campy front derailleur is removable by taking out the little c-clip.Rather than reducing that one,get the right size clamp or another FD.You may advertise on the boards such as rec. bicycles.marketplace to trade clamps or whole derailleurs.You can also use a braze on type with a seperate band clamp from Shimano or Nashbar,QBP etc.

Salsa makes a 45 and a 48 I believe.
You may want to run a triple bb 111mm instead of 102mm.

I have a Chorus triple bb in my garage. I only had it on a bike for a week before getting a new frame with more chainring clearance. PM me if you want it.

I had these same issues building up a Landshark with Campy. For the chainring, cyclocrossworld.com sells TA Specialties campy compatible rings. They're high quality, reasonably priced and available in 46 and 48. I'm very happy with mine.

For the BB width, I ended up using a 2mm spacer on the drive side to gain a little clearance. No big deal. For the front derailleur, It shouldn't be too hard to find a campy clamp-on front derailleur that will fit, or get a braze-on and a $5 clamp-on mount at your local shop.

I've had Record (9 speed) on one of my cross bikes for a year and it's great stuff.

Define "precariously close". As long as you have a few millimeters you should be ok with a 102mm BB. The 111mm triple BB is a last resort, a spacer should do the trick. Remember that the chainring will flex away from the chainstay under load.

I built up my Wazoo with Campy (Chorus) except for the BB and crank which are FSA compact. The clearance at the chainstay is tight but didn't cause me any problems. I really enjoyed having the Campy shifting. I have also been looking for a solution for the front DR on the small diameter tube and have been stuck using an old 105. I'll try one of the suggestions above. Thanks for bringing the problem to light. Hope you enjoy the VooDoo.

After the post-build snowy check ride, it might be time to present some solutions to the above problems.
For the bottom bracket, I installed 2 mm of spacers on the inside of the drive side shell, moving the cranks over as much and providing enough clearance to run a 39 inner ring on regular Record cranks. The spacers came from a 9 speed Ultegra cassette. The non-drive side was still sticking out about 1-2mm and got an old ShimaNO BB lockring to snug it up properly.
The front derailleur got the royal treatment. A 1 1/8th headset spacer (carbon, of course)did the trick. The inside diameter fits exactly around a Wazoo seat tube, while the derailleur clamp can now be tightened up to torque specs. I cut the spacer in half and used one of those extra rubber strip from a cateye computer to protect against scratches on the seat tube and seal out some gunk. I chose the thinner strips with a lip that fits well over the spacer and seals up the opening from the cut.
Thanks for all your suggestions.
