Hub spoke pacing

hub diameter is 38mm
the flange spacing is 50mm
the spoke hole diameter is 3mm for 14G spokes
32h hub and rim

I'm trying to lace a coaster brake hub to a track rim (622 ERD) 700c 41mm wall

Do I need special spokes given the hole is 3mm or would the traditional proper fitting spokes work just fine?

Thanks!

Get the brass spoke washers to make up the difference.

The 38mm number makes sense...

...the 50mm number doesn't. If the spoke hole diameter really is 3.0mm, you should be going with 13g/14g single butted spokes or straight 13g spokes.

The 622 number is not your ERD.

You really should consult with a local wheel builder to get the hub specs measured correctly as well as the rim ERD in order to get a reasonably accurate spoke length calculation.

The issue isn't really the hole diameter, but the flange thickness. If the elbow section has play across the flange and the elbow is drawn away from the flange you want to prevent that by using a washer under the head to effectively shorten the elbow length.
