Hi all,
Needed a boring head and decided to make my own as explained in "Milling a complete course" by Harrold Hall.
Pretty much followed the instructions and sequence in the book.
Fly cutting the contact surface after cutting the dovetail in the body.
Cutting the slots for the arbor.
Marking out and drilling holes in the cutter carrier.
Drilling holes in the bearing plate.
Machining the gib strip.
Undercutting the dovetails.
Making the lead screw.
Machining the dial.
A makeshift indexer was used to do the graduations on the dial.
Lead screw and dial together.
Machining a MT3 soft arbor to fit the body.
Setting up to machine the slots in the arbor.
The finished arbor.
Removing excess from the cutter carrier.
Fly cutting the sides together.
Putting a reference mark on the bearing plate.
All the components before assembly.
The finished product.
Joined by two other little tools recently made.
And fitted on the mill.
This was a nice project to learn more advanced skills and I am very happy with the outcome. Had the opportunity to use the boring head on another project and it works perfectly.
Cheers to all.
Abraham
