Thanks to everyone for your helpful replies.  I will check out the fenders 
you mentioned!  Regarding the tip about screwing the nut on before 
hacksawing a bolt to length ... well, dangit ... such a great idea!

Planet bike alx (aluminum) 50 mm fenders with soma shikora 38 mm tires and r559 
brakes fit just fine on my roscoe bubble v2, which I believe has similar 
clearance.

This struggle (R559 vs front fender) is what drove me to try centerpull
brakes.  I was able to swap some stuff with a listmemember for a set of
Paul Racers, and they're a big improvement.

[RBW] Re: Fender Brands (Besides SKS) That Work On A Sam

[RonaTD]

The rear brake bolt is tangential to the tire diameter, so the brake-tire 
distance increases as the brake gets farther away from the brake bridge. The 
front brake bolt, because of the fork offset, is not tangential, and the 
brake-tire distance gets smaller as the brake gets farther forward of the fork 
crown. Fork crowns are thicker than brake bridges, so there is less brake-tire 
clearance in front than in back. The difference is non-trivial. A constucteur 
tasked with building a fork for a bike that will have dual-pivot brakes would 
do well to angle the bottom of the steerer and fork crown and drill the brake 
bolt hole such that it is tangential to the tire circumference.

I too had that problem with Tektro 559 brakes and aluminum fenders (forgot 
if it's Honjo or VO) on my Wilbury. In the end, it was a struggle between 
getting the fenders high enough to run 650x42B tires, and the brake arms 
rubbing the fender. The tires won and I spent 20 mins slowly denting the 
fender around the brake arms. The brake arms still contact the fenders, but 
only when they're fully open with the quick release. Strangely, the rear 
matching Tektro 559 brake with the matching fenders offers no such problem.

I have a first generation Sam and the VO aluminum 700c 47 mm Zeppelin fenders 
fit perfectly.

My Sam is a 650b, but i do have Tektro 559's. My tires are Soma Grand 
Randonneur 42s, so are probably close to yours in diameter and even wider. 
My all-time favorite fenders are Portland Design Works Full Metal Fenders 
(city size). They are 700c x 45mm size. I mount them to the brake bolt in 
front with a Problem Solvers fender nut, and to the rear brake bridge 
directly (adding a leather washer. PDW FMFs are light but quite sturdy and 
have possibly the best/safest strut release design on the market. And 
they're the quietest fenders I've ever run, my previous experience having 
been with Honjos (with Berthoud hardware), SKS, and Planet Bike.
