How long is the 2x4? And you want to round over the entire length, right?

no the width. the 2x4 is about 3 feet long but I need just that end to be rounded. i will add dimensions to the image. this is an image of the side of the 2x4.

One last question...
Is this for one board or many?
I have done round overs like this by cutting with a jig saw first, then sanding smooth with a ROS. For a more heavy duty sanding job, a hand held belt sander and your skill at using it should be good enough. :grin:
In my case, I rounded the corners of the table top (see pictures). Similar but not exactly the same but you get the idea. Cut it close first, then sand smooth to the line.

correct..
the bit, actually a cutter, does exist but that will take a shaper to turn it... not a router..
what you are showing is the face of the 2by and the ends...
the edge is 1½'' thick...
rough cut it to size and sand to final...
an ROS will do it...
as well as a disk, belt or drum sander...
a disk sander will do the best job..
2nd choice is the belt sander...
make the tool stationary and move/rotate the wood over the sanding surface...
all w/ a little practice you'll get what you are looking for...

This is a job for a bandsaw (or a jig saw) and a disk or belt sander. You will NOT get a round-over bit with a radius of 3-1/2": that's a bit with a diameter of over 7". Instead of sanding you could pattern rout it. You would need a 1/2" collet router and a flush-trim bit with a cutting edge of 2". If the 4x2 is in fact only 3-1/2 x 1-1/2 you could do it in two passes: the first with the pattern and a pattern (shank-mounted bearing) bit with a 1" cutting edge and a second pass (from the opposite face) with a flush-trim bit.

I think this is the end result he is after.

no...
he wants a 3½'' radius..
so that's edge to edge, not face to back as you show...
rotate it 90°...

Use a template and a pattern bit. rough cut it 1/8" larger then finish with a router either hand held or a router table.
