Hydraulic Punch hole size question
Thanks for the responses!
Roger: I think it would be faster to punh the holes than welding/jig
building. plus I now have a reason for building the press :-)

Hi Gang -
In the process of finishing the hydraulic punch and have a question on
tooling.
I have to build a railing (steel) and want to use 1/2" SQUARE bar for
the stiles (vertical) that pass through a rail (horizontal) 2" wide x
1/4" thick flat stock
Should I punch with a 1/2" square punch or go up to the 9/16" punch.
The intent is to weld around the bar when in position. Does a 1/2"
punch actually make a 1/2" hole or is it a little bigger? Also, what
are the tolerences on typical steel bars (when they say 1/2" is it
really 1/2")?
Always drilled and never used a punch before so am a little unsure.
Thanks in advance...
Tom
PS... What else can I do with a hyraulic punch? :-)
