metal lathe if you have room do it you wont regret it.
I am with you, if the guy has the room that is the best way to go. I have a Porper B, and Porper Repair lathe and I certainly love both of them. But I am also in the process of shoping for Metal Lathe to fill the gap for some operations such as threading and making my own Pin's and others parts I currently buy.
By the way, I the cues in the thread you started that are almost finished looked great, I would be willing to bet they will sell as quickly as they are finished, if they are not already sold.
Take care
