Your logo looks too neat to be punched (I think). How do you engrave it? CNC?

Cheers
Roger

The logo has been engraved on a conventional engraving machine Analog, for this purpose I first made a pattern in Linoleum cut. From this pattern a stencil was then milled in brass. This template is used as an engraving template.



This is the logo in linoleum cut.



This is the brass pattern.



This is the analog engraving machine.

A few drillings further it looks like this.
But still not finished.

The jaw is running like a leak.



This morning I still had two hours time, so I worked a bit more.
At the bottom of the vice I drilled the hole for the spindle nut. Instead of 1/2" it was 12mm.
The counter bore was done with a countersink.
I drilled the hole for the spindle in the movable jaw. I drilled 13mm instead of the 3/8". There is a bronze bush for the spindle bearing. The mounting holes for the slide bolt were also drilled on this occasion.
The complete vice was then milled over again at the top and brought to the same height as the fixed jaw.
Finally, the seat of the interchangeable jaws was milled and milled again on the fixed jaw. This ensures the parallelism of the jaws.









I will leave the interchangeable jaws about 2mm above the top of the vice, just like the sliding plate of the spindle.
This way, after removing the interchangeable jaws on the top of the vice, I can clamp flat and larger workpieces on the vice, resting on top.

All elements put together.



Underside of the movable jaw.

And on it goes with the vice.
Today I have almost finished milling the movable jaw.
Dovetail is finished and fits.
Inner cutout for the spindle nut is fitting.
Outside contours, up to the final height and the jaw support is also made.

First I clamped the blank with the upper side (which was relatively straight and did not wobble) on the milling table.
As a stop I put a 12mm fitting strip into the rear guide groove of the milling table and clamped the blank with claws.
Now the underside of the vice was milled slightly and in the same clamping the sides were milled to a right angle up to 0.5 mm.
Now I could place the jaw on the underside and machine the upper side. Here I left about 1mm to the final dimension.
The jaw could now be clamped in the vice, which I had previously aligned exactly with the fine tracer.
The dovetail was next.
First only pre-milled and at the end the dovetail was milled with the HSS milling cutter. First of all only the side that does not get a positioning strip. This was tried again and again to see if it would fit on the vice.
After that the other side was on. Here also again and again try if the adjusting bar fits. A tenth of air does not matter. It is compensated with the adjusting bar.
Now the movable jaw was placed on its lower part and the sides were milled flush with the fixed jaw.
Then the cut-out for the spindle nut was made.
Still to be done, - the cutout for inserting the spindle nut.
- the hole for the spindle, as well as the holes for the set screws and the top .

The dovetail is milled ready.

With the vice I have come further. The lower part of the vice is almost finished. The drillings for the spindle nut and the attachment of the top jaws are still missing.
I had to mill the dovetail again, the selfmade cutter had not shaped the corner properly. The corner radius of the insert was too large.




The corner is beautifully shaped with a groove.


The next step is the moving jaw.

[Bruno Mueller]

I have already pre-milled the actual vice. The dovetail for the movable jaw was already finished. I also milled the seat for the actual vice jaw.

The milling of the clamping plate and the outer contours is still missing.

The hole for the clamping nut will be machined later.

[Bruno Mueller]

I have started a new project.
It shall become a vice. I found it at Hemingway in England and used the favorable exchange rate.


I ordered the material set and after a few days it was there.


The drawings are once again, as usual, given in inches.
So everything converted and adjusted.


When everything is ready, it should look like this.


Yesterday was the start. Part 1, I finished the base plate. The 360° graduation and the fitting of the pass strips are still missing, but they will be attached later.
First the cast blank was clamped onto the large face plate chuck and the bottom side was turned flat.
Then the center of the round casting shoulder was torn on the upper side. I did this with the centering angle. Again on the faceplate chuck this center was aligned and drilled, and the hole was turned out to 19.5mm and reamed with a 20mm reamer. The surface was turned so far that no casting skin was visible and the surface was smooth.
Now the 20 degree bevel could be turned. The inner heel was turned to the required depth and diameter. The center was supported with the rolling center punch and the top of the clamping flange was turned.
The groove for the clamping screws of the actual vice was cut to the required depth and width. For this purpose I ground a recessing steel from a broken off 6mm carbide cutter.
Now the part was taken to the milling machine and the outer contours of the clamping flange were machined.
Finally the mounting holes were torn and drilled. The positioning of the holes was based on the conditions of my milling machine table. My T-slots are 50mm apart.
In order to clamp the vice on the lathe (I have a groove distance of 75mm there), this dimension was also taken into account.
A 19mm hole to the groove was drilled from below.
Now I could clamp the base plate with a 20mm clamping bolt on the rotary table. Through the 19mm counter bore I could insert a T-slot milling cutter with 6mm shank from below and clamp it in the collet chuck of the milling machine and finish milling the T-slot.





To be continued.

Thank you, Bruno, even though I can't read the German instructions, the drawings and your photo of yours are very plain. I think I will give it an attempt to build.
Thanks agin

Bruno, your work on the Pillar Tool is very impressive, but I would like to see and know more about you ball turning tool. Did you make it? Would you care to share some information on it ?
Thanks

The ball turning device was published in the German magazine "Das Dampfmodell" in issue No.1/94 page 30-31.
It is made of a holder which is clamped on the top slide of the lathe. Exactly in the middle of the lathe, there is a bearing hole in this holder for a rotary axis. I have inserted bronze bushes there. A movable slide is mounted on a rotary axis, which in turn holds a cutting tool holder.
This can be seen on the drawing.
The cutting tool is adjusted with the cross slide exactly to the center of rotation. With the movable slide, the diameter of the ball can be adjusted.
By turning the axle the ball is manufactured.
I built this device in 1992.






this is my device

Today I made knob screws for the Pillar Tool.



Turn the ball ends with the ball turning device.


At the other end a ball was also turned on. Afterwards the arm between the two balls was finished with a 2 degree bevel.


Here we drilled and cut a M6 thread for the stud bolt.


Finished toggle screws.


And here at their place of destination.

The Nonius is an invention of a Portuguese navigator mathematician from 1542. He was from a town just 50 Km from where I live

[Bruno Mueller]

In Germany, vernier (Nonius) is a common term for fine graduations, be it angular degrees or distances.
So you can also find a nonius on a caliper gauge. The measuring drum of a micrometer gauge also has a nonius in this sense.

Yes, my region is very much influenced by the French language. We were under French administration here after the French Revolution until 1814. After World War I and also after World War II we were occupied by French troops. In the regional language many French vocabulary and words can be found.

Here is a link to an article about this time.

I hadn't seen "Nonius" used that way so I had to look it up. It is a way of dividing into finer segments, originally developed for the astrolabe and consisting of concentric circles, each with a different number of divisions. That was subsequently refined to the vernier by the French mathematician who gave it his name.

Is Nonius a more common usage in Germany than Vernier? I'm sure the French have their home town favorite and had the impression that it was an almost universal term.
