Just a quick note in case this might save someone a trip to the hobby store:
The Du-Bro 3/16" wheel collars require a 13/32" tube not 3/8". Even the 13/32" is an awfully tight fit, requiring a small bit of fine sanding to the outside diameter of the collars to allow easy sliding. I'll let you know if the Boca bearings fit these collars when they arrive.
--9/23/10 Update: The Boca bearings arrived and they do not fit in the Du-Bro wheel collars. The bearings have an OD of .1950" and the collars have an ID of .1905". I thought about getting a .1945 reamer but I'm guessing it would cost way more than simply trying another brand, such as those from Great Planes.
-I'm almost to that point where I wish would have purchased a commercial solution instead of trying to make my own.
