1 1/2 inch Boring Head. I need one for light duty work inside of a crankcase. It will be Brass. Pic #1 shows flats for 3/4 wrench. Pic #2 Back side complete with 1/2-13 threaded mounting hole. This one is slightly altered from one by Stephen Campbell.

The parts that make the adjustments have to go somewhere. That's a 1/8 endmill and it's crankin. I'm whipped, time to stop for the day. Pick this up again tomorrow.

A change was in my plans, so a new base is being made. I had not givin a lot of thought for the mounting of the head. I used the 1/2-13 thread to use a home grown 1/2" straight arbor. The change came about because a MT2 Arbor is available with a 1/2-20 thread and also the 3/8-16 drawrod thread for under $6.00. The new base is to the left. It will utilize a 1" wrench.

Nothing like spending quality time with your machines. The bad habits of the world just seem to disappear.

Ready again to cut the Dovetail and the pocket for the inerds. There was a discussion on using air at the machine. That can of air (Computer Stuff bought on sale) is the only air I use. I have air drops in 6 places in the shop used for air tools only.

Adj. Pocket is done. Sorry about the clarity but the flash on brass is hard to control.

Yep -- Those are the prints I have, I only changed the mounting thread so far. The show a 3/4-16 and I went to a 1/2-20. I want to make a smaller one if this one works out. Maybe 1 inch in diameter isstead of 1.5 inch diameter.

Nice work Bill,

....Sorry about the clarity but the flash on brass is hard to control.
If you cant/dont want to take the pic in manual mode, just try holding a piece of wax paper in front of the flash.

Cheers Phil

Bill, You are a machining genius! Tell your wife I said that and you need more than an hour in the shop because we need the instruction.

After the dovetail on the body, all that is left is the dial and the slide. If the cutters do not arrive tomorrow I will grind a tool and Flycut the Dovetails. We are missing closer. :lmao:

Well, I couldn't get it to you any sooner than that anyway, short of paying high priced Saturday delivery. It's here if you need it though.

HMMM -- I called the PO. Next day delivery on that would be $37.50. I could buy two more cutters for that price. :lmao: OK -- my morning hour in the shop is over. There are two parts left to make. The Dial (5) and the Keeper (7). I will finish the slide and make those last two parts this afternoon. All that should be left after that is the Dovetails themselves.

The brains (6-40 SHCS and part #4) in place. I need to make the keeper (part #7). The action is smooth at this point. If anyone wishes to build this little Boring Head I can supply the 6-40 SHCS if you can't find them.

Now the bad news (expected). UPS does not deliver on Saturday. I called and my tooling is in Watertown, 12 miles from here. They will not let me pick it up. I can have it emergency delivered for $67.75. Looks like it won't get done till Monday when my tooling gets delivered. I have gone as far as I can for now except the Dial. I want to do that last. See you Monday, same time, same channel. Good Night Mrs Kalabash whever you are.
