Hi. I have an aluminum piece with a hole. There was a tube pressed into
that hole, but I pressed it out and want to install a different tube. The
inner diameter of the hole is slightly larger than the new tube that I want
to press fit into the hole. The new tube can be inserted into the hole
without a press fit, but it does not rattle around. This is not a tight
enough fit. It has to be a press fit. I am hoping there is a tool to
reduce the inner diameter of the aluminum hole so that the new tube is a
tighter fit. From searching around, it seems that I may need a knurling
tool. I have a 20 ton shop press, and I am hoping to find something that I
can press through the hole to make it a smaller hole, causing a press fit
for the new tube and aluminum piece.

Does anyone have any suggestions on what to do?
