I know this is an old video but I wanted to take the time to tell you that it's still providing useful information for folks and to say thanks. I just tried your tramming alternative procedure and it worked better than I can do with a Last Word on a bar in the spindle. I used a precision shaft chucked in a collet and because I couldn't afford a cylindrical square I bought a couple of 2-4-6 blocks (affordable, and I can use them for other things) and stood one of them upright to judge against with a bright flashlight held behind. I moved the block so that a surface not interrupted by the holes in the block was against the shaft and it was done in a matter of 5 minutes. That's a great time saving tip for those of us who don't work to tenths precision.

Keith, great machine trades 101 education video for the new guys just getting to know their mills. I’m sure a lot of veterans will also have their eyes opened by the power & precision that their eyes along with some well-placed light as compared to a precision surface can have. After all, the main purpose of that precision machinist square you had there is to check for squareness of a part to easily within .0002” to .0005” simply by comparing the light enhanced gap along the square blade and the part. In my early days as a tool maker I built metal stamping dies & the method used to do the final locating of the pierce punches concentric with the hole in the die block involved only light & sight. By equalizing the beam of light shining around the circumference of the punch your eye (and brain) can position the punch within .0001”, (also referred to as a “tenth” in tool maker slang) of concentricity with the hole. Again Good stuff, Jim Cunningham

Keith, the more you show the Wells Index mill, the more I like it. Looks like a well-designed machine. For those who haven't seen them, both John (Doubleboost) and Tom (Oxtools) have shown use of large Diesel engine wrist pins as cylinder squares, and they appear to be a less expensive alternative cylinder square...especially if you know a diesel mechanic with access to used parts. Not magnetic, but stable enough by use of gravity. Thanks for the demo! -- Mike

Hi Keith. I was dreading retramming my mill. I copied your technique using a 12" engineers square and a precision ground 25mm dia steel bar I use when calibrating my lathe. One finished, I clamped an indicator to the mill spindle, and I ran the pointer up and down the edge of the square. I was delighted to confirm I was within 0.002" over 12". From start to finish, the process took less than 15 minutes. The last time I trammed in the mill by swinging an indicator held in the spindle, to took half a morning! Thanks for a great tutorial. Stuart

I think the cylinder allows you a very close initial alignment because the two aligning cylinders allow adjustment of both axis on initial setup due to the cylinder geometry. Because the meeting surfaces are both cylindrical, their contact points if not parallel with each other on both axis, will show gap out of the gate, not so with the square. IT is absolute for two cylinders to connect if both axis planes are parallel with each other. Absolutely great stuff ! I never really gave the cylindrical set up any thought. Thanks madman, always great info. You ARE the man!

Kieth,the old timers taught me ,to make a ring about as wide as the table say 8" . And say 2 1/2 wide on flat.I other words a fat wide ring 1/2 inch thich. Make this on the lathe ,finishing it between centers, IN THE SAME TURNING. LIGHTLY CUTING BOTH SIDES down to the center. When done three jaw chuck on the od and bore away the small untrue portion in the middle. Thus you end up with a PERFECTLY FLAT circle plate. You then lightly clean your mill table with a file lay the ring on the table ,then chase your tail using a regular bigger indicator than the last word. You have to tap the head side to side bare handed with your hands,no rubber hammer either,you can still dent it! Do this untill the mill head is On ZERO. IT HAS TO BE PERFECTLY ZERO. if not when you fly cut you will have a concave surface.ITS A PAIN,I can be done.Try 2 indicators at once set at 90 degrees and you will chase two tails."They" make a tool with 2 indicators side by side, dont know who but its pricey!My ring is at the foot of the mill in the oil pool by the knee jack screw.How do we exchange emails privatly?

Thanks for another great video Keith. What's your view on locking dowel pins? My Elliott Super 16 has nod and tilt dowel pins that lock the head in place when it is set true. I have done a sweep at 12 inches in tilt and 5 inches in nod and it is true to less than a thousandth. Is there any reason some machines come without them? Set up is easy, simply get close, slip pin in and tighten nuts. Can be done in less than one minute. Vernier scale for tilt and nod are calibrated to zero with pins in. Have you noticed how a lot of machines have quite crude indications that are,at best, only a rough indication of angle? Having an accurate angle indication makes life easier and faster with the knowledge you don't need extra checks to ensure you are absolutely spot on.

@nickp479311 ай бұрын
A table would typically be cleaned and lightly stoned before placing vises on it or tramming in the head using 123 blocks. The stones don't remove material like if you were sharpening a knife. You are just feeling for high spots caused by knicks, and can tell when they are gone then you stop stoning.

Hello, Keith been a Machinist for 39yrs I still hate Tramming a head no matter how many times I do it a soon as you tighten the head bolts it moves a thou or two I like to have everything Zero . and that's on a Bridgeport in my home shop I have a Burke Millrite MV mill that's a little different it does not tilt back or nod only side to side but the thing is it has no adjustment screws for the head like a Bridgeport . you have to leave the head bolts snug and tap it with a soft mallet to adjust it . also if you adjust the head on an angle you must hold it and loosen the bolts or it will swing out of your hands
@VintageMachinery8 жыл бұрын
+1995dresser Tramming can be a pain. Tightening things moves it a bit, and what I have to do is anticipate how much it will move and tighten it into tram - a delicate balancing act. At least my Wells-Index is well designed and fairly easy to adjust.
