|Thread: Tapping drill size|
I have spent a lot of time machining threads and before metrication, I had a book around 1 1/2" thick which had a different thread form on each page. A couple of the more interesting ones ( I just had a wry smile thinking what a non engineer would think about an 'interesting' thread form) were a screw thread for a bottle closure and a steam coupling thread for the hose between rail carriages.
|Thread: Bearing fit|
Yes Ian, that's certainly the approach I would take.
|Thread: An interesting repair to an Hour Wheel|
Being involved in maintenance engineering for a long time, I think that it's a brilliant repair : )
|Thread: Bright EN24T steel vs Black EN24T for cutting gears|
I believe that cold rolled steel has a greater yield and tensile strength due to the manufacturing process.
|Thread: Clock #1|
Just in case you haven't seen it Gerry, there is the excellent Clickspring's use of silk thread here:-

|Thread: Clock #1|
Fascinating indeed. I think I would have used a different word other than 'seductive' !
Hello Gerry, that's not just 'thread' that's 'silk thread' !!
It seems that the idea comes from old french clocks. The odd idea appealed to me so I used it.
The thread is suspended from a screw at the top which can turn to adjust the length of swing for fine adjustments.
As for fatigue, I'll let you know!
Thank you Max and Bill

Very, very nice Neil.
|Thread: Pivot repair|
Just to hi-jack the thread, Thank you for the link Michael, very interesting.
|Thread: Fixed steady use|
Would it be possible to put a centre in the end of the bar with an electric drill? I've done this a couple of times successfully.

|Thread: Bushing for clock arbor|
Hello Alan, that's fascinating, thank you. I wonder where the preacher got its name?
Michael, thank you, yes, I understood the emphasis.
Thank you Roy, an end mill would work but I was interested in how a clockmaker would do it.
Hello Michael, Ahh! thank you, simple when you know how : )

When a clock needs bushing, the hole is usually extended to one side. When drilling the hole for the new bush how would you keep the hole in the correct place without allowing the drill to centre itself mid way in the stretched hole?
|Thread: English style bracket clock by John Tyler|
Seems strange, I've just had a look at the advertising for the book and it says:-
" However the author has provided instructions which leave nothing to chance. The construction of the fusee in particular is fully covered and two appendices at the end of the book deal with the theory of the curve."
