Thread: 2mm Milling Cutter
17/04/2012 01:55:02


After breaking a couple of 1mm and 2mm slot drills on my cnc I now almost exclusively use carbide (pcb) engraving cutters on brass and gunmetal. Now I can do small milling with confidence and have never broken one of these, I am using 1mm wide cutter for most milling but down to 0.1mm or finishing and engraving.

One problem is, although my spindle max is 10,000 rpm, it's much happier at about 6000 rpm so not great.

Mind you these slot drills, although new ,were not great on sharpness, they were cheap but expensive to break.

Because the engraving cutter has tapered sides, sides need to be finished will the slot drill/endmill but for some jobs it does not matter.

I am using a small Sherline I converted to cnc.

These engraving cutters have one flat side like a 'D' bit, the 0.1mm cutter (very sharp) actually makes a good scriber point, the flat edge helps when scribing a line along a rulers edge.


Thread: spline shaft cutters

Splines can be of involute form and cut using an internal gear shaping method.

In a jobbing shop internal splines may also be done by spark erosion (EDM).

 Or wire erosion

Thread: Toolmaker's Clamps
06/04/2012 03:06:13

When it comes to tool makers clamps, size is not everytrhing.

I made some from 3/16" square bar and about an inch and a bit long. 6BA threads if I remember correctly.

I bet mine are not the smallest though.

I would very much appreciate it if you could pass this message on to Lukas Walter, I am sure he is a very kind and generous person and I would like to give him this wonderful opportunity.

Unfortunately the aforementioned Sir Ashley Owen finds himself in a bit of a pickle and rather financially embarrassed. As a victim of scammers he lost all his money from his UK bank account, now without funds he is unable to access his offshore millions located in a bank in Timbuck Two. It saddens me so much to see my dear friend and employer in this very difficult position, I only wish I could help him myself. Without access to his offshore funds Sir Ashley's estate will fall into ruins.

If Lukas could send some money to the amount of 5000GBP Sir Ashley will than be able to release his offshore funds. If Lukas would be so very kind to do this Sir Ashey will generously reward him by paying 200,000 GBP directly into his personal bank account. If Lukas would be so kind to post his full bank details on this forum Sir Ashley will transfer this money promptly.

Kind Regards

Butler, Chauffeur, Cook

Thread: Alpine Mill/Drill

If the 3MT /2MT sleeve protrudes below the end of the spindle a little you could turn a blank disc the diameter of the MT sleeve, weld it to the end of the MT sleeve, then drop a bar down the spindle bore and tap it out.


Turn a piece of bar to 2MT and loctite it into the sleeve, place a bar down the spindle bore and tap it out.

Thread: What is EN24 like to machine?
23/02/2012 17:48:22

Hi Rakesh

Here is some info on heat traeted conditions of EN24.

Can't realy give any specific help with heat traetement but I guess you will heat to cherry red, soak at that temp for a while, quench in oil, temper to a light purple. This might help.

444HB converts to 48 RC


Thread: The dreaded drilling job!
20/02/2012 16:44:53


I cannot remember the exact arrangement but there was a method given in ME similar to that shown below. This arrangement allows you to position the drill and determine the drill exit point.

Drilling cylinder ports

maybe others have used this method?


Thread: buying copper for boiler makeing
20/02/2012 16:27:26


When riveting for silver soldering should you stop short of completely closing the rivet in order to maintain a few thou gap the for silver solder to flow between the joining surfaces.

I understand it's important to maintain a few thou gap to get a sound joint?

Use Notepad which is a text editor or download the free Notepad++

If you want to use text from ms word you can avoid problems by pasting it into notepad, then copy that and paste into your post.

Thanks Terry

OK, (as mentioned by others) by going to the tools menu and adding this website to compatibility view under compatibility settings, everything seems to work.

test in compatibility view

But where do I find the embedded code fo rthis youtube video?

using explorer 9.0.5

But I don't think it's acceptable to expect users to have to change default settings just to be on this one forum. Not everyone is confident making changes to their settings.

Wondering what all the fuss is about thought I do my own test.

Test 1. Failed

I typed some text, highlighted it and clicked the add link icon, Explorer went white and freezed up so I had to close the page.

Using windows 7 64 bit & explorer 9.0.5 (updated yesterday)

This is test 2 - text only.


(Apparently I can't spell my name)

Well test 2, text only works and can be edited.

I find it much better when links in posts are set to open in a new window
Most don't seem to do this.
Makes it a little easier to get back the ME post.
Thread: Rolls Royce engines going global in Singapore
03/02/2012 16:54:06
For the last 3 years I have been working in Singapore (needs must) so have some direct experience in this area.
The Singapore government wants to modernise and increase their manufacturing base by attracting high end foreign manufacturing companies; they also want to improve the skills of Singaporeans so more of these jobs go to local residents thus less dependent on foreign workers.
To this end the government is investing heavily providing very attractive training and startup grants.
Their economy is not dependent upon credit, is very stable and has fared as one of the best during the current recession; also they are well located for the growing Asian market.
With all the European economy problems and growing markets moving east I think you can expect to see more of this happening.
Thread: Drilling brass - seizing
02/02/2012 01:59:35
If you sharpen the drill with one flute slightly longer than the other the drill will cut slightly over size.
Not good practice but maybe will prevent jamming?
Just a thought.

Hi Robert
If it's 2 Dimensional then machining the image with cnc should not be a problem. If the image can be drawn in a 2d cad package a dxf file format can be saved which is ideal.
With the right software it's also possble to use images in Jpeg or pdf file format.
If for some reason your requirement is 3 dimensional, then the most convienient approach would be to model the part in a 3d cad package from which can be saved an stl file format.
