HankMcSpank I think you have just began to realised that getting the lathe is just the start, there is an seemingly endless variety of tools and attachments for the lathe. For my boring bar holder I used some square stock that would fit in the tool holder put a large drill in the 3 jaw chuck and pushed the metal against the drill, then drilled and tpped 2 holes perpendiculer to the hole to hold the bar in place voila, one holder.
My biggest problem is in finding suitable stock to make things usually for a few £'s more I can get the article ready made at times it dont make sense in that the finished article can come from china but a bit os steel jst down the road costs an arm and a leg plus postage!

Keep up the learning process
