    I need to clamp a very small round rod to CNC mill, any ideas?

    Hey everyone, Pretty new to machining.

    I have an aluminum rod that is 1/2" thick, and about 1.5" long.

    I need to do some machining on about 8mm on either side of it, and some drilling.

    I am struggling to find a good way to clamp this to my bed or my vise.

    I tried making a small clamp by basically cutting a 1/2" thick piece of 2" x 2" aluminum and drilling a hole in the middle with a 1/2" drill bit. I then cut it in half and screwed and tapped some holes to connect both sides of the clamp.

    It works OK, but I am having a very hard time getting it perfectly squared up.

    Anyone have any other ideas?

    If the V block is too long, machine it down until it is the length you need.

    A picture of your part would help to suggest hold down methods.

    Cut and drill another block but this time only slit one side instead of cutting it in half. Place the block in a vise, insert your part, tighten.
