|Thread: 1/6" x 28tpi tap & die.|
Phil, thank you for your offer but I have that one with corresponding die. I did consider going to M5 but the washer only had a bore of 4.6 mm, and being made from that very hard and brittle material are not easy enlarged. Niko.
OK, not the greatest engineering event making 10 screws of 1/6" x 28, but musical box restoration is much donkey work before it gets interesting, on the rigth is one of the damaged original screws. Asked a quote for a special made die, if they give it will I let it know. Niko.
Yes Phil, those are the comb screws, you would like to keep it as original as possible but they can have had a hard live giving you no other option then to make slightly larger sized ones. The 0.32 & 0.38 mm module is another of those problems, you can try this one **LINK** . I use a 19th century rounding-up machine and cutters to make it mesh the other gear in the governor. It goes a little over 0.40 mm modern module but the Swiss must also have had rounding-up machines for large size wheels, but sofar never found one. I think your loft will look similar to mine. Niko.

Thanks for the help, however it is a full form thread. Niko.
It must be some kind of Swiss size from 1870. It is used much in musical boxes from that period. Many times the thread on the screw is gone and I have to thread cut new ones which takes too much time or use an oversize which is not ideal. Niko.
No, I am looking for 1/6" x 28, if it exists.
Perhaps someone knows a supplier for tap & die 1/6" x 28 tpi. I have tried to find one with no luck. Niko.
|Thread: Which oil for blueing steel screws?|
You can use water, it is only for stopping the colour from running further, the only advantage of oil is that the steel will not rust if you forget to remove the water. Niko.
|Thread: polishing clock plates|
Leave the plates a little oversized, polish them to mirror finish, aply a tape to protect the surfaces as good as possible, then cut them to size and drill and tap the holes. Niko.
|Thread: Best quality M2 taps|
Small size good quality taps are indeed spendy, the time you bougth them in the hardware store around the corner is long gone. I returned the 1.4mm ones from Bergeon since 110 euro ex. VAT was a shock. Niko.
|Thread: Myford Super 7 chuck alignment issues.|
Try fitting a catch- or faceplate first before you try a chuck, because you can acces the thread of a those plates from both sides they are easier to clean, if they fit you know the spindle thread is fine. Niko.
You will have to check the spindle thread very thoroughly, small chips can embed themself in the thread and swiping it with a cloth or brush will not remove them. You will have to remove them with a small tool. The same is true for the thread of the chuck you try to fit. Niko.
|Thread: Ebay chuckle|
Same with me, have it now for over 30 years. German made it came with a Rohm 1-13 mm drill chuck. No idea what I paid for it but not much. Niko.

|Thread: Getting to be short sighted: Vision Magnification advice please|
In warm/hot weather the headband of Optivisor becomes very uncomfortable for me, it makes me sweat a lot. Niko.
|Thread: Did we go to the moon in 1969|
Best is to send Trump with a Russian rocket to the moon so he can check for himself if its fake or not. Niko.
|Thread: Jaeger 4 day car clock|
you can mail them and ask what the nearist is they have. 0.22 mm will be difficult to get, normal is 0.20 and then 0.25 mm. if you have acces to a surface grinder you can easily make the width smaller altough that leaves a very sharp edge that will happily cut your fingers during assembly. niko

|Thread: Westminster Attack 22 March 2017|
One year after the Brussels atacks again we are shocked by another barbaric act. Regardless of Brexit we as Europa must stay together and form one front against those very sick persons who do this. Niko.

This is perhaps worthwhile buying, they try of course to sell there products but it gives also useful information. Niko.
|Thread: Stalling Lathe|
Before you make adjustments, which should be minimal, mark the position of the split collar and the left adjusting ring for rear bearings. It gives you more control over what you are doing and you can easily return to the original setting. Niko.
