Ultra-Small Boring Head - Bill Gruby - 01-19-2013
I need a small (under 2 inches) boring head. I need to work inside a crankcase. I found one searching the net. 1 1/2 dia. It is light duty only so brass will do fine. I have scraps. Pic one is the main body with falts for 3/4 wrench. Pic #2 shows the 1/2-13 mounting hole also.

Make up a flycutter. Done that a couple of times for smallish dovetails. With brass, you don't need carbide or anything, just some HSS.

That's easy enough, thanx Tony. Sure feels good to be back in the shop.

Glad you're back with the living, Bill. I had a spell with it, and still don't feel 100%, but you're right. It is good to be in the shop. I ought to be there. I have a couple of jobs running behind.

I hope none of you gets this strain of the Flu. It's awful. I have been down for two weeks now. I am still under quarentine for two more weeks.
OK, I'm gettin tires. I have started the openings for the adjustment parts. I will pick this up tomorrow.

Glad to see you back Bill. I agree with Tony about using a fly cutter ,I would file up a cutter from drill rod and harden it, you have got better control of the shape I think
Best Regards, keep getting Better--- Brian.

Looking good so far Bill.
That will make a nice addition to the tool collection.

I have been changing things already. I found MT2 Arbors with 1/2-20 Threaded ends. Also they are threaded for 3/8-16 Draw Rods. All this for less than $6.00. The new one is at the left.
