I had always thought that a billion was 10 to the power of 12 not 9?
|Thread: 'Bad Referrer' message when trying to view the Archive.|
Thanks Dominic that cured the problem for me.
I'm rather curious thou. Why hadn't it stopped all the Banking Credit Card Company and purchases on-line?
|Thread: Why are BA taps so blooming expensive??|
I've just bought a set of even taps and dies 0 to 10 BA from Tracy tools with postage and VAT came to what you just paid. They are not HSS but carbide but I'm sure they will last me out.
Remember standing by the fireplace when this stranger appeared at the window. "That's your Dad" my Mum said. He had just been demobbed. I was 4.
I have memories of being in a smelly air-raid shelter. The street where I lived until 9 is now Vann Walk all the old houses were flattened around that part of Belgrave, Leicester.
I well remember the queues when sweets came off ration which must have been in the early 50's.
Going to the Science Museum with a couple of mates on the train from Leicester Central to Kings Cross and on leaving the station not being able to see more than a couple of feet in the smog.
Being attested at Cardington in 1958 when I joined the RAF. and travelling by train with all the other recruits from Cardington to Wilmslow ( steam of course) which basically took all day as it was a special troop carrier and had to wait for all the normal traffic.
Even later in the early 60's driving from Kings Lynn to Leicester with my then girl friend (wife since 1963) and the fog as night descended making a familiar journey from the outskirts of Leicester a nightmare. Thank God for smokeless fuel.
I believe all of us born during or just after the war have had a period in history which has given us great opportunities but feel it is going to be much harder from now on.
Now I'll stop swinging the lamp shades.

If you are making Harold Hall's small marking out gauge from his "lathework a complete course" book I hope you have better luck with the adjustment mechanism. I just could not get the 6mm threads to match.
|Thread: Mini lathe chip pan|
Quickly made from a bit of odd aluminium. Fixed to the travelling steady holes with M6 screws and a washer glued under the head. The holes in the tray have slots up to them hence the tray can be removed and replaced quickly. The screws tightened with fingers. As it is the length allows cuts right up to the chuck and the width keeps the lead screw from the great majority of the turnings. If I make another it will have a higher front side and the end that goes under the chuck would be made just to miss the chuck. I'd also make larger headed screws.

|Thread: Harold Hall basic grinding rest|
I think you mean't to ask me re the vertical sliding mount.
With the mill sharpening holder on the table the end of the mill is so high on the wheel that I need to raise the grinder.
It will come in handy anyway.
I built this rest about 4 years ago and am quite happy with it other than there is a tendency for the table to rotate as it is only relying on the friction of the countersunk screw holding the table to the plastic ball to stop it.
Otherwise it work well.
Having now made Harold's Mill sharpening holder I've now got to make a vertical sliding mount for the grinder.
It is typical the one thing always leads to another.
|Thread: Cross drill attachment - Super 7|
Thanks for pointing out the "Code of Conduct" I thought I was getting senile when my first post vanished. Now with the LINK removed the first part doesn't make sense.
Thanks Carl that clearly answered my question.
Is the kit you are referring to:
I have been researching how to do this. It looks great
Will it fit and drill parallel to the head stock?

|Thread: What Did You Do Today 2020|
Having taken advantage of the 6 for a £1 offer for Model Engineer I was looking at the on line digital copies and was taken by the Oliver Evans' Half -Beam Engine from Dec 2001 on.
I decided to start with the beam which is somewhat complicated the main structure starts with 2mm thick material which I managed to cut from an extruded of material which seems like dural.
The beam has an arc both top and bottom which although the plan doesn't describe the radius I reckoned it to be about 635mm.
The attached photo shows the length I had to go too to get this on my Warco 14.
Has anyone else made. This model as portrayed in the articles?
|Thread: Basic Harold Hall Rest movement|
Having made Harold's simple grinding rest a few year ago now I am at a loss to why the question from Johan. The tilt gives the necessary tool angle and the fine adjustments the tool advance. Both covering all that is necessary.
The only drawback to this original design is that the single screw fixing the table to the ball does, if one is not careful, allow the table to rotate.
The only other complaint re the simple rest is;- Having made Harold's milling edge and end sharpening holder it puts the end of the mill too high and the simple grinding rest doesn't go low enough.
This means I will have to raise the actual grinder DOH!!!
Bob. It sounds as if you have never watched Harold's video's

|Thread: Shoe repair glue advice?|
Yes. Don't spread it too thick. Use some form of spatula, a lollipop stick will do the trick
|Thread: Morse tapers|
We did have slide rules though and they did sin/cos/tan etc.
Back at school 63 years ago it was the mnemonic "Silly Old Harry" Sine of the angle = Opposite divided by the Hypotenuse.
Therefore Opposite = Hypotenuse X sine of morse taper angle
Where Opposite is your block height.
MT2 = 1.4307, MT4 = 1.4876.
For MT2 block height = 5" * sine 1.4307 = 0.12483915376791831054202224797354"
For MT4 block height = 5" * sine 1.4876 = 0.1298030051564469002522710354277"
Good look with that.
|Thread: Keeping busy|
I remember my children buying me a slide copier. As you say it was rubbish. I attacked the problem in a slightly different way. Hung the screen on the wall mounted my camera above the projector and did the lot.
The results were good. I just wished I'd washed the slides first.
That must have been over 20 years ago.
|Thread: ER collet chuck/mill incompatibility?|
Sorry I don't know why I attributed that to you.
