Topic: Edge Finder Question

I generally use the .2. There isn't a huge amount of difference, sometimes a situation calls for a finder the same size as the shank it's on, sometimes you need to get in a small spot. Pick one. The one thing I'll say is don't skimp. Get one expensive, mechanical edgefinder with a .2 or .5 tip (i go...

Every machinist in my shop, including four classically trained tool and die makers, uses a standard one pound soft face hammer (or handy chuck of metal) to do four jaw alignment by tapping it on EVERY size lathe. Guys who can square a block of metal with a file? Yeah. They're swinging hammers and bl...

One thing that kills me occasionally is the rear jaw gets dirt behind it somehow (I have no idea how) and when it is tightened, the hard jaw itself moves. As you tighten it, put a DTI on the BACK of the hard jaw, and torque it down. It should not move much, if at all. If it does, take the jaw off an...

You say that machine shop experience can only be gotten in a machine shop and HSM experience can only be gotten at home. OK, Now what? If you really think I mean this, still, after all the attempts at clarification I've made, I have nothing else to say. I can't force you to understand a point you d...

I'm sorry to everyone on-topic for starting to hijack this thread - I'll bow out in a post or two if this doesn't clear up. I'll happily reread your statements, again. I'm only trying to get you to quit generalizing. The whole point of my posts thus far had two, and only two points: First, that ther...

So, T.D., you apparently believe that machine work cannot be learned by study. According to you, one must have worked as a machinist to have any understanding of the trade. I am not saying this, and I wish you'd stop setting me up as a strawman, intentionally or unintentionally. I am not making the...

So we are looking for only true machinists, eh? It sounds like, according to some anyway, a home shop machinist who is more or less self-taught will never be able to make the grade. I thought that was the point of this website. I think the lesson here is that you will never, ever learn certain thin...

I am a production machinist who has also been to school for machining. I think you guys are starting to mistake the analogies you're using for the situation itself. I think Kant would say we're arguing about a pure representation here, in the absence of an intuition of the possible object represente...

We stick tenth indicators on all our height gauges instead of those little feely doodads they come with. Really helps with the consistency, and then you can also use it to check part geometry, hole location, etc quite a deal faster. .... that dreaded .100 error, when using an edge finder. .... Even ...

Am I the only other person who has stopped knocking parts down in the vise? I used to do it, but I get much better flatness and parallelism without it. The only time I knock a part down is when I know the jaw is lifting and can see it on an indicator. And then my first course of action is to disasse...

Any reason not to use the spot drill and go in far enough to create the chamfer, then drill with the 3/8? Then you only need to do 2 tools per hole. Reason I ask is I've seen it done that way at work when they make fixtures etc. When the hole is to be threaded, the tap follows. So 3 tools in that c...
