Spindle Adapter

I recently acquired a dividing head at the Grizzly tool sale in Springfield. I would like to use my lathe chuck on it but my lathe spindle is larger than the dividing head spindle. I thought about making a bushing but my threading skills aren't too good yet and I'll need to make a boring bar. I haven't tried to thread internally yet so I expect I'll making more than one of these before I get it right.
My question for you guys is, will a bushing work (assuming I get it threaded right) or...
