What i have seen done is use a 100 degree punch and punch around the hole
as
many places as possible forcing material into the I.D

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?

Hi. When you say "100 degree punch", is that the angle of the point??
Sorry, but I am not real familiar with that.

I am going to take some pictures and some measurements later, then make
another post to try to help clarify all this.

Thank you.
