Thread: What to use on my Sherline mill to round off pinion wire leafs
13/12/2019 22:46:42
Posted by roy entwistle on 13/12/2019 21:57:36:

The Module or DP would be wrong . you can get away with .5 Mod but that's about it How do you know what the diameter should be? If it's just one pinion then I would use a file


Never tried and perhaps in a clock you can get away with .5 Mod, but is it not .05 you mean since in a musical box governor it would wear out the corresponding wheel in record time. Niko.

Thread: Where to find these larger staking punches?
10/12/2019 16:59:24

Yes, that is of interest, thanks Michael.


10/12/2019 12:42:13

A little of topic but I have never seen a staking tool for larger diameter punches or is that due to my poor eye sight? They all seem to be for 4.7 mm diameter punches which is not a very handy choice, 5.0 mm would be much more practical. Niko.

Thread: What is it?
06/12/2019 12:15:39

It is for opening watchcases, see**LINK** Niko.

Thread: Back saw for cutting steel and brass?
27/11/2019 14:31:38

When multiple heads come next to each other in a row I use a slitting saw to make the slots, it is a much neater sight when they are identical. With only one screw head a piercing saw with the correct blade thickness will do fine. If the head becomes very small when the thread is below M 1.0 a piercing saw with the smallest thickness of blade is best to use. A screw-head file is much too wide that work. Niko.

Thread: Uhrenindustriemuseum Villingen, Germany.
23/10/2019 21:40:21

Last week traveling in Germany I visited the "Uhrenindustriemuseum" in Villingen-Schwenningen **LINK** . It is in the old Kienzle factory which closed in 1985. Most of the machines from around 1920 are still present and working. Best to bring ear protection to limit the noise if you take the tour which is done by old workers. The one in the picture makes the hammers for a alarm clock. Niko.

Thread: Metal Shear - info request
05/10/2019 13:04:09

This dealer **LINK** states for the same type but for a width of 600 mm for steel a max. thickness of 1.6 mm, stainless 1.25 mm and alu 2.5 mm. Niko.

Thread: Why are washers such a poor fit?
24/09/2019 18:57:59

Well they are dual use and a perfect fit for a 1/4 inch. Niko.

Thread: PayPal Warning
13/09/2019 10:32:24

On the Dutch PayPal site under the heading "Payments" (Betalingen) you can stop authorising Ebay to automatically debit your account. Niko.

Thread: Myford 254 thread dial indicator
09/09/2019 12:38:45

Is it not possible that the imperial TDI is the same as used on the 7 series? Niko.

Thread: Anyone know where I can get hold of 'Gauge Rods'
07/09/2019 17:42:08
Posted by JasonB on 07/09/2019 17:04:23:

Just to further confirm that gauge (US gage) pins are being referred to have a read of this where Jerry is mentioned several times and his sketches used.

It is certainly nice work Mr. Kieffer does but If I work according to his method I would not be making money at all. Niko.

Thread: Bushing for clock arbor
30/08/2019 12:04:37

The smallest round files I have is Vallorbe LP1680 nr.2, diameter starts at 0.60 mm. Niko.

Thread: Your ideal holiday
21/08/2019 21:14:07

A few, limited to the UK; visiting the Scilly Isles by helicopter, the garden there is one of the finest, or drive from Inverness to Scrabster and take the ferry to Orkney, or drive the Hardknott Pass but do take a small car and not a big Yank Tank as I did the first time. Niko.

21/08/2019 12:07:54

In not to near future it is perhaps easier for UK citizens to have hoiday in the US. Niko.

Thread: Black Oxide coating
11/08/2019 22:16:49

A little of topic but today I blued several small parts but two M1.7 mm screws which came from package which I bought did not colour. I replaced them with new ones I made from silversteel and that of course coloured without problems. Any idea what steel the others are made from, perhaps stainless? Niko.

Thread: Advice for a mini milling machine
24/07/2019 15:20:36

For clock parts it is not necessary to work at 0.01 mm accuracy. Clocks are driven one way and normally 0.10 mm is more than accurate enough. Niko

Andrew, Your posts are always interesting to read, I sincerely hope you will continue, Niko.

Thread: Wobbly slitting saws
30/06/2019 00:17:16
Posted by Watford on 29/06/2019 22:11:17:

On the subject of slitting saws I am having difficulty sourcing a very small example. I need a 1/2" dia. x 1/16"wide saw to produce a key-way in the crankshaft of a Channel Island Special 10cc. I require to get up very close to the crank web without marking it.

Can any kind soul point me in the right direction, please?


Fraises & Outils SELECTION SA, Zwitserland,  nr. 500.0121705 has a diameter of 12 mm but thickness of 1.70 mm. They probably will alter the thickness for you if you ask but will be costly. Alternatively you can clamp a thickness of 1.00 and 0.55 mm together, it will create a wobble but not much because of the small diameter, probably around 0.02 mm. But you have to try first to determen if it is OK. Niko.

Thread: Is it bad practice to lock my Myford lathe using the slow speed lever
24/06/2019 10:27:23

It is the wrong way of doing it but in 40+ years the backgear on the lathe I have is still fine with no damaged to the teeth. Several small taps is better than one big blow with a hammer. Niko.

Thread: Silver soldering cast iron?
18/06/2019 14:55:12

The CI must be as clean as possible, I sandblasted it first the few times I have done it. Niko.
