tilting vice

I bought a cheap tilting vice from Machine Mart recently. It is certainly not the most sophisticated vice in the world but it is a big chunk of metal for the money. Before I start to tidy it up, may I ask whether anyone else has done so? I am particularly interested in ideas for fixing a degree scale to this item.

MEW issue 12 August Sept 1992 – Article on improving tilting vice. (Probably the same one as yours.)

Thanks John, but Sod’s law has struck once more with unerring accuracy….my collection of back numbers starts at issue 14.

Lapsed a couple of months ago, I am afraid. Time to get back on board I suppose.

Hi Mick,

Search on this forum for “sine vice”. Nobby has a nice picture of his modified vice on that thread. I have one of these which I need to modify to get the pivot parallel to the base and the jaw faces.

Thanks Les…..that is a nice job that Nobby has done. If you are reading this Nobby, what else did you do to it, other than what you mentioned on the sine vice thread?

Is the vice from MM their Clark CTV25B in which case it is very similar, if not identical, to the vice in issue 12 which was an article of mine. In those days the editor was not allowed to give his name as the author.

However, I am, having now ceased writing for the magazine, started adding to my website a large number of my articles written over the twenty years( about 40 already). I have though started with more recent ones where I have used digital photographs as I have disposed of the prints I had previous to this. 2000 prints was far to many to search through as I had never indexed them.

If you need more info than is on the sine vice thread I will consider adding my article within the next few days. Due to the problems of the pictures, and I also have a problem using my DOS based text files, I may chose to add it to a temporary web site that I use if I am not happy with result. In this case leaving it there for couple of months.

If you indicate you are interested then I will proceed and when available I will post the address here.

Incidentally, it is quite a large task as it is necessary for all the important surfaces to be correctly positioned in relation to the pivot pin.

Anyone interested in my recent additions could look at

Thanks Harold. That is an offer that cannot be refused. I am sure that there will be others who would like to see that article. I am a bit nervous of embarking upon the job without some form of guidance and your paragraph regarding the relationship of the pivot pin to the other surfaces is exactly why.

Nice big writing on your pages, easy reading for tired old eyes.

I will get started today (Saturday) or Monday latest.

 

Thanks Ady, Probably because they are being produced by tired old eyes

Hi Mick H & guys

I have been having problems with my laptop sorry about delay answering . I have added angles as well you can just see them near the pivot point . These are for quick setting ie 20 30 45 etc. I am sure Harold will contribute to this thread. I miss his articles in M.E.W. I have made a grinding vice & a adjustable angle plate I will upload them in an album later

My thanks to everyone who has assisted me in my request for information…I look forward to Harold’s posting on his site.

[Harold Hall 1Participant @haroldhall1]

I have now established a web page for my Tilting Vice Improvement article and am reasonably happy with it so have added it to my permanent web site, the pictures are not that good but just about adequate.

Go to http://www.homews.co.uk/page61.html

and click on Project 39

The project is a major task, but worth it if the budget vice is not that good and it is to be the milling machine’s only vice, at least initially. It is also a good project for the newcomer wishing to learn more about using a milling machine.

[michael howarth 1Participant @michaelhowarth1]

Harold, you weren’t kidding when you said the modification was quite a large task.

Nevertheless a very worthwhile project. Thanks again.

In addition to the above, I would like to mention that College Engineering Supplies (CES) have a small toolmakers vice as a casting kit to which is attached an article from MEW no 17 on how to make a tilting vice of the same type.

I’ve got a tilting vice with a degree scale, but since purchasing one of those little digital angle gauges I don’t use the scale any more. The angle gauge is far more accurate and much easier to read.

[NobbyParticipant @nobby]

Hi Gary

Does the machine have to be level ? Please see sine vice thread

Regards Nobby

[Gary WoodingParticipant @garywooding25363]

Hi Nobby,

No, the m/c doesn’t need to be level.

The digital angle gauge is zeroed when on the table, and thus shows the inclination of the vice relative to the table when placed on the vice. This is pretty easy ‘cos its magnetic.

It’s not, of course, as precise as using a sine vice with gauge blocks, but 0.1 degrees is more accurate than a degree scale, and much easier to use. Another consideration is that sine gauges get progressively more cumbersome and less accurate at angles greater than 45 degrees. For a 5″ sine gauge the difference in height of gauge blocks to distinguish between 60.1 and 60.0 degrees is 0.004356″.

For ultimate accuracy, the sine gauge (vice) is king, but for most jobs 0.1 degrees is acceptable.

The vice I use can tilt on two axes, and the angle gauge can handle either with equal aplomb.

Hi Gary

One of these would be useful with my tilting angle plate.
