If SB shows a .6020 taper that is what you need to know. If making an adapter for a center, I suggest making it a bit smaller at the large end, that way it will be recessed, about -.010 dia. should be enough. Norman #4 1/2 morse taper is about 5.375 long [gage line} Big end 1.5", taper of...

Awhile back I made some spindle adapters for Rockwell lathes and others. The common problem is folks confuse taper angle, with taper size-MT. Each Morse Taper # has an angle and a size. When used in the spindle bore, the Morse ANGLE my match a certain MT, but the size is not even close. Morse...

What sort of work holding will you use with the Rod. 3/8 NC is tough sometimes depending on material. Scored rod from slipping in the chuck/collet never shows well. A diehead is what I'd use for the threads, work in a collet, but if material is more than mild steel, you may need a dog driver as...

Most engines (full scale) have the crankshaft C/L offset to the cylinder C/L. This to reduce the angle of the connecting rod on the power stroke. This will increase engine torque a bit. combined with offset in the piston wrist pin, makes the piston skirt bear a bit heavier to one side, thereby...

I made my Corliss rings as the drawing showed. First turn the outer diameter, place piece of brass, in one of the chuck jaws, half the thickness of the offset, so a .015 will yield 030 offset in the ID. Then measure for half the width. And make the cut, flip an do the other side of the Z. I...

To expand on what Ken posted. A gun drillbit does not look like a drill, a long shaft with a straight flute or two to carry away the chips, a hollow bore to flow coolant to the cutting head, which is a carbide head with 1-2 cutting edges. I use a lathe for deep drilling,( Cannon barrels)so the...

As a kid I used to return deposit bottles to the deli for change. Then go to the hardware store and buy 000 steel wool pads. Then wrap a small candle in paper, then wrap the steel wool around. When dark bend a coat hanger around the steel wool and light it off. Then swing it around, the sparks...
