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

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'

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.

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.

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.

Thread: Hardening a form tool made from Gauge Plate
14/06/2019 22:36:53
Posted by SillyOldDuffer on 14/06/2019 17:34:01:

Perhaps a clockmaker can advise? What's the best way to harden small parts?

I am not a clockmaker but with hardening small parts you have to make sure the tool with which you hold it does not act as a heatsink . I use a stainless tweezer to hold the part and make sure that is heated first. Also of course your jar of oil is as close as possible without catching fire and burning the place down. Niko.

14/06/2019 18:57:02

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
26/05/2019 11:25:07

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.

You can use a carbide drill, like these**LINK**


Thread: Circular lathe mounted file disc

Perhaps this one is cheaper. Niko


Thread: Blacking engraved lines
11/02/2019 12:11:35

Carbon black works fine to colour epoxy resin, if you do not have you just crush some Norit tablets. Niko.

Thread: Tempering
31/12/2018 12:16:43

For me the easiest way to controlled temper is the flame of a spirit burner with just enough heat to the reach temperture and the object inbedded in a tray with brass filings. Niko.

When the oven fails I still have a industrial one as back-up, go's to 900C, probably high enough for the turkey. Niko.
