trying to drill a 7mm hole in a 16mm round bar(mild steel) goes in straight but comes out off centre at the other end.
I drilled a pilot hole 1st but still come out off centre.
I get every thing lined up square ,I've use a lathe jaws but still does it.
so the best thing for me is to try and get a precision tube .
all I can get is 12mm with 6mm bore.
what I need is at least 14mm or more with no more than 7mm bore.
but can I hell find one.
so do you guys know where I might be able to get it?
even looked at threaded tubes but at £1.75 a pop and I use 4 at a time.
so thats out.
