The detailed pics are above.
The rag joint sprocket mount interferes with the 3-speed hubs ability to spin at it's brake arm to hub pivot point.
Unlike a coaster that just has a nut on the axle against a bearing behind the brake arm, the brake arm and the entire 1 7/8" 'dust cover' end piece are on piece, and compressing a sprocket on it won't let the actual hub spin free.
The customer insists on a 3-speed so I went to Maniac Maniac's site to get a hub mount sprocket on it's way only to find they only go up to 1.77" hub size, I need 1.875" to fit that hub.
I e-mailed Jim a couple of times but no reply yet so I may just end up having to make this a free jackshaft job unless I can talk him into swapping his Tahiti bike for a 7-speed Pantera, same bike, just different drives and a rag sprocket will work fine on that.
