Or to put it another way - how to stop my mill vice moving on the table.

Its a beast of a vice must weigh 20kg - its bolted down to the mill table with 12mm tee nuts, but it still slides along the table when I'm milling something.

I'm at a loss as to why - i can't physically move it when not under load but as soon as I make a cut it slides.

Must say its not all the time and it only moves a few mm but as you can imagine its a bit annoying.

Tips and tricks please.

Thanks for the Link - great read.

Thanks for the detailed answers - I had it in my head that the extra drive was needed to rotate the head in normal operation.

I understand the Helixieseezze's idea - maybe in the future if i ever need to cut one i will try to get it working properly so I can cut a "spiral "...

As you can see - there should be a gear (bevel) to help turn the other bevel gear.

Its defiantly a bevel gear drive that's missing - I can work that out from where the original handle would have been - I will attach a photo later.

Seems to me that most run a 40-1 final drive but how do I work out what the missing gear is.

I take it there is a mathematical formula for such ?

I will add some photos later.

Hi - recently been given a tilting dividing head - can't find a makers mark on it yet but it looks very well made.

It looks like it was taken apart for some reason and the main drive bevel gear is missing along with the handle - the surround doesn't look like too much work to make a new one but the bevel gear is my sticking point.

How do I work out what gear ratio it needs to be - ive not counted the teeth on the gear that remains yet but that's my next job.

It has - Komet JBV 3/810 etched on the side - its slightly worn so can't make it out properly

Its approx 1" square and 300mm long

Thanks for the replies - i will get a bit more info and some measurements plus a picture of the WNMG insert (the 06 and the 08 ) next to it.

I have a large boring bar but for the life of me I can't seem to work out what insert it takes - From the shape I assumed the WNMG type but neither the 06 or 08 fit.

Or is it an internal threading insert and its not a boring bar

Can anyone help please.

Hi - I'm pretty good at cutting tapers now having been "thrown" in at the deep end if you like with my Herbert Tapered Milling machine.

Setting up for the taper is the easy bit - the boredom of removing the metal is the hardest part to endure.

Theres plenty of "how too" videos on Youtube and believe me Ive watched them all...... Yawn.....

I am constantly on Ebay always looking - Plenty of L0 and L1 but the baby is proving harder to source.

I looked everywhere on the Ebay and came up with the nothing like that - that is exactly what I'm after.

I'll send them a message now. When you search there own web site it doesn't come up.... maybe it's me.

I'm not fussed if it was an unfinished project, a casting, billet or a finished article - I just wanted a L00 backplate.

Exactly what I want to make my own - .....

I think the RDG ones are too small for the L00 taper - unless i'm looking at the wrong thing.

Anyone know where I can get a blank to make a backplate for my chuck, its to suit a L00 taper - Harrison 140.

Seems to be a serious lack of L00 taper backplates.

Well I think that just about puts that to bed - and as for the above comment - you could have fooled me.... LOL

I thank everyone for their contribution to this thread - I'm sure somewhere along the way I sort of got an answer to my question. I think the answer was - sell the Mill and buy a puppy much less to worry about.

PS - I do know why but when someone that doesn't know what the picture is of, then it does confuse very quickly.

Is it just me (as in Me) - why when you look at this picture the line a 12 o'clock is straight up and down but when you turn the picture through 45 degrees the new 12 o'clock line is not.....

Have I discovered a floor in the dividing disc design or is it just an Illusion....... Spooky....

And also - why the line at the 6 o'clock position has half the amount of holes when you look at the picture as posted - Anyone have Pythagoras's phone number I think hes missed a trick with this.

Phew - thanks for that.

I'm never going to be sure I will ever have to rotate my table/Head....(when i get one) by 5.29 degrees, but when I do I will know how to work out which plate hole combo I will need to use.

I was sure it was 42 - now I'm not.....

......
