Converted Non Ai Lens

Today I took my dads Nikkor 45mm 1:2.8 lens that is non Ai and tried converting it.  I looked up how to do it online and it didnt seem to hard. 
Instead of filing down the aperture ring, I just took it off.  The only reason I wanted the lens was because it is good in low light.  So i kept it on f-stop 2.8, put the lens back together and started using it.

This is the lens, it is very short and stubby.  Only about a inch and a half thick.
Here is the first good photo I took with it.  My dad wanted a photo of our dog and I think this came out pretty good.

Pretty sharp for a 1960's lens.  I like.  A little bokeh in the back too
