|Thread: Further to Bill Bryson......|
My wife's uncle Claud was at Bletchley as a radio operator. In part of his role he was assigned to various spies & was able to tell when one had been compromised by the change in style of morse code. The Germans would try to deceive us by carrying on the routine & giving false messages. We would realise & play the same game.
He was a radio ham & known all over the world. One small room of his house was dedicated to his home built gear. He loved doing morse ( the hobby was gradually dying as it gave over to speech) The speed at which he could send & receive morse had to be seen to be believed
Many years later he was reading about radio opps at Bletchley & read an article that 9 operators were so good that they could receive & decode 2 incoming morse signals at once ( The Nazis used to send morse over morse to confuse us). He announced that he was one of the nine & had no idea that only 9 could do it & although working there throughout the war he did not know any of them
He was a really lovely old man and when he would have been 100 ( died some years earlier) the whole family had a re union in his memory
His call sign was "George 2 Dog Peter Queen."
I have a yacht & the electric autopilot is nicknamed George. I have a second one which is an Aeries wind steering autopilot. I could not call it George 2 so it is nicknamed "Uncle Claud" ( from George 2 etc)
When the going gets rough & the electric autopilot gets overpowered "Uncle Claud" always gets me home
|Thread: Cutting with a large tap|
Not as long as one might suspect. If you google " rigid pipe threaders" you will see that the head is not particularly big & handle is about 20 inches long.not very long when one has 20 threads a day to cut even in modern times. I have to admit when i last watched a chap he had a sort of electric drill with die at right angles to cl of normal drill drive
I used to watch heating engineers, assembling school heating systems, putting threads on 1.5 & 2 inch steel pipe & they did not seem to have any trouble. The more senior in years among us may well remember the heating pipes running round changing rooms & classrooms with reducers at the old CI radiators. Not allowed now for fear of scalding kids
So how come a tap is harder to use than a die?
|Thread: Universal Coupling|
Model power boat propeller shaft/engine couplings
|Thread: Warco WM16|
I am due to get delivery of my M16 next week. Knowing my luck, i am bound to make a mistake. So what advice do you give to prevent your problem. How, for instance, can i check & adjust meshing of the gears
Is it easy to replace? What should I look for when it all arrives. Have I bought a pup?
Any advice please
|Thread: Trubble at Matelot Mill (VFD drive issues?)|
One would have thought so, but on the BBC programme it indicated the section of the ship where both generators are fitted suggesting that they are side by side
I believe the Russians have now got a DVD of it
Knowing our lot, the backup is probably an Ipad- at least they work!!!

Watching the item on BBC news they showed a room full of computer screens
I could not help thinking that a hit from one 6 inch shell would make the entire ship inoperative
I suppose the same would happen if one hit the generators
Seems weird that there are no backup systems
|Thread: Details for a scroll saw|
Actually I had thought about that. I have 4 or 5 jigsaws from my joinery business & had considered just making a blade grip. & doing exactly what you suggest. The variable speeds would enable me to experiment.to get best cutting speed. I already have a startright bandsaw
I just fancied trying some gear cutting & making the eccentric
Edited By Sam Longley 1 on 26/01/2016 20:42:33
I want to make a scroll saw for thin metals, grp sheet, ply & balsa ( model aero building).
I would appreciate comments on the following:-
1) How many oscillations per minute do forumites reckon I need. I will have a simple eccentric & the number of revolutions will govern the number of times the blade goes up & down.
2) How far up & down would you reckon the blade should travel. This will govern the size of eccentric. is 20mm enough or too much? Should it be faster & less stroke length or slower & a longer cut. Presumably the upper spring will have to adjust to this & thus govern the stroke. But it must affect operation somehow
3) I seem to recall a standard single phase motor of about 0.25 HP runs at 1450 RPM. Is that correct? & any ideas where I can source one cheap?
4) I will cut the gears from tufnol as I have only just bought the lathe & mill ( Promised delivery Friday-- Hurrah!!!) so I want to go easy on the cutters.
So how big should the teeth be. I know the ratio is set by number of teeth to number of teeth but should I be looking at very small teeth. How does one decide on tooth size on gears . Is there a table somewhere that one follows. Would smaller teeth be better on tufnol ? Bigger may be easier/ quicker but will the tooth snap off? should I have small teeth for quieter running or will they just strip off?. Or is it decided by the divisions available on the dividing head?
Finally - No; I do not want to buy one. Half the fun is making it ones self
|Thread: upgrade subscription having made mistake of buying digital|
I get the reply "Activation failed! this code you entered has already been issued
Yesterday i paid for a digital subscription of model engineer. It has been a disaster.
I spent 2 hours trying to upload it & finally managed to get the October 2015 issue on my computer. It takes ages to load & is either so small I cannot see it or so large that it is just as unreadable. I tried to get it on my Ipad & gave up after struggling with passwords etc. All I , i get is requests for payment for individual issues & my order number seems invalid
. Another go tonight & as far as I am concerned i might as well have thrown the money down the drain.
Is it possible to upgrade to a posted print subscription & dump this digital mess?

|Thread: What do you think of MEW as a magazine|
Birthday in Feb & 4 titles have already been selected. Just see what transpires
That would be a good idea. All I need to do now is follow the links & find out how to subscribe.
by the way- Apologies to the mods for putting in wrong place.
Being new here means i do not know my way around yet & there are many different blocks of thread. The notification email is not as good as some & i do tend to forget where i have posted. Too many blocks is my first thought. Buy Hey! I am new here
So what do forumites think of model engineers workshop as a magazine?
Years ago I used to have RC&ME which had lots of engineering articles. Now, however, it is aeroplanes & helicopters. Whilst I am a member of a model aero club I find the mag disapointing as it does not give much " how to" info
So having seen the note that there was an article about the Drummond ( i have an "M" I shot off to W H Smiths. Disaster, - not on the shelves. If the mag has lots of info on machining I will invest in a subscription, but if it is all about steam trains chuffing up some valley or other than it will be of no interest
However without getting my hands on a copy i just wondered if model engineers actually think that it is an informative mag, or like a lot of magazines - all about someone's latest holiday
Finally - why has that little smiley plonked itself in the script? have I a little lodger?

|Thread: Cast Iron cutting depth|
Yes - Thanks- I have seen the video & whilst it is very good the chap does go on a bit--- as do a few others-- Just wish they would get on with the machining
But informative all the same
I also have the book by Andrew Smith on building the 10V which, having bought at the show, I have not read yet
Edited By Sam Longley 1 on 19/01/2016 17:50:29
I know that when one machines cast iron they have to get below the case hardened skin.
However, I am about to start machining a cast iron Stuart 10V & the feet of the stand seem liable to cracking off
So the question is :- How deep does the first cut have to be to get beneath the skin & how deep can one go with a small item like the 10V stand before one is likely to snap the legs off
|Thread: London MEX 2016 Photos|
I am really fed up now -- I missed some of those !!!!!!
& mine fitted & worked very well on my laptop - So thanks for taking the effort
|Thread: What do i need for my new setup|
Well the payment has been made & delivery arranged for within 10 days
i bought a Warco WM 250 lathe The WM 16 mills. Do not know if I have made a good choice or not. Time will tell
Accessories were only, fly cutter & some HSS inserts, quick change toolpost, set of indexible cutters. Collet chuck & collets. set of end mills, toolpost die holder. I did want a boring head but was not sure what sort. I need a better vice but my existing one will do until I have had some experience. Could not find a Glance holders so just bought cheap to get a start
I nearly bought a rotary table but another model maker I spoke to advised me against the one I was looking at as he felt it was not suitable for a mill. It was him that advised me against the WM 14 mill as he said one never has one big enough & he had already made that mistake. I need some means of dividing but am not sure what yet.
I have some tools plus tool post chuck etc & a selection of HSS cutters , cut off tools , between centres boring bars . measuring gear , dials etc so i have something to experiment with
So I am just going to play around & get a feel for things. I have some Tufnol parts i need to make & that will keep me occupied for a couple of days
So once I get it set up I will just machine some bits & see how it goes

|Thread: small pump|
I know a number of people have suggested buying something & i do have the rotary pump suggested above for my nitro planes. I also use a hand pump on one of my yachts inboard engine. JasonB's little pump is brilliant & i could cut some tufnol gears to a crank to get it pumping fast
It just seems like a nice little project to try & a chance to extend my skills. I think I will give it a go just for the " non flying" days
