Alain,
You may need a bigger machine. The fact that you are using the tailstock/steadyrest is a problem with a connection that far away from the chuck. The TL-3 Big Bore has a 8.8 or so hole. I really don't think you will have a lot of luck with a Tl-3 standard machine if you are doing a lot of connections and crossover subs. Have you tried to use the tailstock and the steady rest at the same time? I know that will only help with the pin; however, that's half of the battle. Post some pictures of the toolholder and the inserts and such. |
