I use the base guards with good results.I dont like the grooving tool,it displaces the lead to much if you go to deep.You might try the diamond nurling tool (were is my spelling proof reader?)I like that It holds enough lube.Good luck with the project It's been rewarding for me.You will like thet RCE.press,it's worth waiting for its a tough machine and the dies are exelent Cal.
