If you Masturbate you will go blind.

I find the two bits of advice similar.

Probably get flamed for this, but I like to put the vise off of center cause seems like I always have some dinky setup that I can't use the vise. Now I have alittle room to mount my setup,etc without moving the vise.

I'll join you in the flame room, because I mount the vise a little to the right of center so I've got room to set a rotary table or a larger part to the T-slots on the left if I need to. It doesn't come off and on very much so wear to the table is not issue. And I customarily work from the left end of the vise because I can indicate the fixed jaw, zero the dials and always know the position of a part in the vise, unless I reset dials for a particular part.

I may rot in some machinist's hell for it, but it's been fun in the meantime.

Hehe, funny John...

I also like to put mine off to one side. It lets me get at that oiling screw that most people forget. And it lets me make small(ish) no-vise setups without removing the vise. At this very moment I have temporarily setup a tilting table (and spindexer) right beside the (still trammed) vise for a small job.

There used to be a DIY expert on the TV called Harry Green...that always told you ...over and over again to go round all three holes in a drill chuck whilst tightening ...with dia warnings that your chuck will wear out or the drill will come undone if you don't.


still cant figure out the logic of that.

anorak wearers and train ticket collectors take note

..if you were to number holes 1-3 that would be better ...use 1 ...next time next day use 2 ..and after that 3 and back to 1 again ..thats if you could be bothered..

What ever works for you. Machines are made to wear out. at some point in time. All that means is it is then used to do a little less quality work . as it wears some more you do a little rougher work on it . At some point a shop will sell it and buy new, then we go ape over it.If you have any kind of decent machine and Don`t abuse it . and are doing HSM stuff it will out last you who ever you are. and after we are dead and gone it wont matter.

Mark, that Harry Green sounds like a pretty smart guy. I proved to mysellf yrs. ago that if you will go around all three holes on the the chuck it does improve the grip, and sometimes the runout on jobber drills. I always do it.

Any chance the guy simply knew what the errors were when it was right "there" on the table, and put it back "there" so it (he hopes) will be "just the same as last time"...?

I think that is slightly delusional if you mean to the nearest thou, but whatever. Still could be the point he was making.

BTW, I have noticed that most people, when trying to explain or teach, will make some "definite" statements that they likely can't back up. Dunno why, I have done it, seen others do it.... and have noticed that people who don't quite understand their subject do it more.

Darrell Hollands machine shop videos are the best instructional videos that I have seen to date. To those that would flame them Why not go to work and raise the mark. One good result of this discussion is that several different views and the arguments to support them have been presented. I may not agree with any or all of them but I have a better basis of understanding to support which ever corse that I choose to follow.

[IOWOLF]

When it all boils down ,Is it not Just an opinion if you can't prove it?

I for one will put my vice off center,where I want it. Things wear out,I bought a used mill and expect to buy another when it wears out,If it wears out a year sooner because of vice placement so be it.

[J Tiers]

Argument #1: "it's the middle with equal hang-over and will shift the least when milling, besides being affected the least by table droop, so it's the most accurate".

Argument #2: "that's the area that is and will get, worn the most, and consequently will end up the least accurate. Other less worn parts of the table will be more accurate as the mill wears".

In the long run it probably don't matter.... some things are almost superstitious... The local baseball team used to have a shortstop who did backflips on his way to his position when the game started. It got to be a tradition that he did that, like he had to for them to win.... But later when he was older he didn't do them, and he played just as well....

So long as the guy doesn't carefully mill a pocket for the vise in the top of the table, it probably won't hurt anyone if he likes perfect symmetry... Some folks have weird fetishes like that.
