I have a milling attachment for my lathe (think a mini rodney style) and things are going well adapting it to fit on my lathe. One area is causing me some trouble however, toolholding. The spindle has a 3/8 24tpi female thread, I have drill chucks which fit this thread no problem but I don't want to drill with this tool, I want to mill with it so how am I going to hold milling cutters?
