Inlaying small nut into aluminum block??

[NVMM]

I'm trying to inlay a small nut into a block of aluminum. It's going to be on the bottom so you won't see it. I'm going to run a bolt through the top.
I have all the small hand tools including a Dremel tool. I was going to outline the nut on the aluminum and cut the outline and then epoxy the nut in place.

I don't have alot of machine shop experience. I would appreciate any advice you could give me.

Thank You
Michael

Is there some reason you don't want to thread the aluminum hole and do away with the nut?

Hi enfield. The aluminum block goes in to a frame and is alined with a pin so the hole in the aluminum and frame are the same size. I do not want to alter the frame. The bolt I will use is smaller then the existing hole. I want to tighten the block to the frame so there will be no movement.
Thanks

Have you considered using something like a heli-coil?
Just to do a bubba job I would just drill a tight hole and hammer the nut in.

Using a flat bottomed drill, drill a hole the depth of the nut and the diameter across the flats. Then take a small chisel , like a gravers chisel and cut out the corners.

Thanks mete

Thank you for the expert advice. I'm going to do exactly what you said.
It will look better than I thought it would.

Actually what I would do instead of a nut is use a piece of steel rod or tube. Tap it to the appropriate thread size. Then drill a hole in the aluminum block and press-fit the new "nut" and adhere with anerobic adhesive. That way you only have to drill a round hole to fit the nut.
