A standard boring head would take too much space on my small optimum BF16 mill. So I decided to make my own:

-40mm height (without shank and boring bar)
-52 mm diameter
-Spindle M7 x 0,5
-Dial: 0,0125mm per division (40 divisions)
-10mm Boring Bars

Making of:
 
That looks great!

Nice job ! I made a 2" boring head fer myself a year or three ago, it sure feels good to use
a tool that you made fer yourself. I posted mine in the shop made tool forum also ..............
 
I had a look at it there. Interesting design and it also looks very well made. I downloaded the drawings and will study them.
 
Very cool! Is this the Steve Campbell design boring head? If so I made the same one about a year or so ago except I used a 60 degree dovetail and made a few minor changes to meet my needs. I needed a small accurate boring head and the Chinese ones just wouldn't cut it so I made my own. It works very very well and is solid. I plan on building another one (2" diameter) and I am going to make a few changes so that I can use an indexable attachment like Mesa Tools makes for the Criterion heads.

Nice machined boringhead you made!

Thanks for the tipps with the mesa-attachment. - Very interesting addon that is now on my todo-list and needs further research..

I also have a 60° dovetail (copying the design of randy richards for the cutter) and I never heard of the "Steve Campbell Design" - just looked at several solutions and made my own version for my small mill. Also planning an even smaller version...

Thanks. The 60° dovetail was my initial concern but it made no difference at all. The only reason I see now to use a 45 over a 60 is if the boring head is even smaller and your looking for more contact area of the dovetail.
 
Here is a link to another pic of the Mesa attachment that shows you more of its construction.
