|Thread: Uhrenindustriemuseum Villingen, Germany.|
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|
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?|
Well they are dual use and a perfect fit for a 1/4 inch. Niko.
|Thread: PayPal Warning|
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|
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'|
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|
The smallest round files I have is Vallorbe LP1680 nr.2, diameter starts at 0.60 mm. Niko.
|Thread: Your ideal holiday|
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.
In not to near future it is perhaps easier for UK citizens to have hoiday in the US. Niko.
|Thread: Black Oxide coating|
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|
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|
Fraises & Outils SELECTION SA, Zwitserland, https://guye-outils.ch/presentation.php?lang=en 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|
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?|
The CI must be as clean as possible, I sandblasted it first the few times I have done it. Niko.
|Thread: Hardening a form tool made from Gauge Plate|
I have no problems using oil to harden parts made from gauge plate but they are very small in size. Larger parts gave problems when using the same size container filled with oil. You need a good size container for quenching in oil, better larger than smaller, otherwise you cannot get rid of the heat fast enough. Niko.
|Thread: Turning long slender arbors|
When diameters get small it can be handier to make a male centre on the arbor end. A female centre in the tailstock is quickly made with a piece of brass in a drillchuck and centredrill held in the headstock chuck/collet. Niko.
|Thread: anealing piano wire|
You can use a carbide drill, like these**LINK**
|Thread: Circular lathe mounted file disc|
Perhaps this one is cheaper. Niko
