FYI. While building my Surley Pugsley BBHSD conversion, with the Luna Eclipse chainring, I needed to add 2 spacers to the chainring (ie, between the chainring and the BBHSD mount) so the chainring had clearance from the chainstay. I mounted the chainring, but then noticed that the teeth were not spinning parallel to the plane of the bike, they were a bit wobbly. Removing the chainring and the spacers revealed some 'slag' bits on the edges of the spacers, that would prevent the chainring from sitting flush against the BBHSD unit.
A few minutes with a flat file takes care of the problem. Seems to be a problem only on one side of the spacers. First photo illustrates one side, the second photo shows the clean other side. Just make sure those spacers are flat and all is good!chainringSpacer.jpg
