|Thread: Is your spindle bore large enough?|
The job will always turn up that is bigger than your headstock bore, it will be time to get the fixed steady out, the nice thing about a big bore is you won’t need the steady out so often. If the bore size you have is a regular nuisance then maybe a bigger lathe may be required. As a Myford 7 owner with the small bore which is widely derided I have not had to use the steady very much but it will all depend on what you do on your machine.
|Thread: Posilock Chuck|
You must use threaded shank Clarkson type cutters,the design of the chuck relies on the thread to force the internal tapers into position.
|Thread: Lathe - dead centre wont reach the workpiece|
John Stevenson chose a rather drastic solution but not a problem for a man with his skills.
|Thread: Adjustable 3-jaw chuck designs|
Was it not Commander Barker who recommended the undersized register and oversized bolt holes? He maintained that he had never had a chuck move in use while using this technique. I would be slightly wary using a heavy interrupted cut but typical model engineer operations would probably have no problems.
|Thread: RENAULT DAUPHINE|
Just bin the rest of the car and put the Imp engine in a racing sidecar outfit
|Thread: Any uses for an old tired lathe bed|
Did you replace it because the old bed is beyond being reground? If there is enough meat for a regrind then it may have some value to someone. Maybe a super long bed could be rigged for making cues or the like.
|Thread: Things to Come|
My iPad has no GPS but google maps is near spot on with my location, they know where everybody’s WiFi is and have it mapped, an easy job to work out where you are within a few meters. Sometimes the tech can be useful, I went to the Goodwood Festival of Speed and forgot where I left my car, luckily my phone remembered where it lost the blu-tooth connection with my car and helpfully highlighted on the map where my car was. Would have been handy 35 years ago when I parked at Luton Airport in a bit of a hurry and a week later had to play hunt the car for ten minutes, before the days of remote locking so had to look at all the red cars.
|Thread: Jim Al Kahlili : Revolutions|
To return to the original topic, I have finished watching the car episode and enjoyed it, these programs always leave you wanting more if you have geek tendencies but I doubt the majority of the audience would want that much detail so the programs have to be commended and may whet the appetite of some youngsters to get interested in engineering.
|Thread: Things to Come|
Perhaps they will send me a few free ones for the plug.
I go down the pub and talk about all sorts of random rubbish and when I get home Facebook and google bombard me with adverts about my discussion subjects, I must leave Siri at home and see if they still know what I talk about, I tend to use cash down the pub so I doubt they know that Old Speckled Hen is my favourite tipple. Big brother is watching us.
|Thread: Jim Al Kahlili : Revolutions|
Cyclists round here seem to think they are on a somewhat slower Tour de France, a cycle may be a low pollution device but the long queue of cars waiting to get past the peloton are using much more fuel than they would just cruising at a steady speed. The acceleration required to pass safely uses much more fuel than just making steady progress. The big picture is that riding a cycle on narrow roads probably uses more fuel overall than if they used a car, bicycles are probably squandering the earths resources rather than saving the planet.
|Thread: Upgrading to fibre optic broadband|
Broadcast TV is probably going to be a thing of the past in the not to distant future and at the moment blu-Ray and streaming are the only terrestrial options for 4K viewing. We are being pushed more and more into using the internet and todays gadgets like video doorbells and pet cams will become normal and then indispensable. Even those without internet access like my mother and wife’s mother still get things done for them by us so they are not internet free. A home with a couple of kids streaming the films of their choice and adults catching up tv are going to need a decent connection speed, before my youngest son left home and before fibre to the cabinet came to the village we regularly stalled or buffered, I upgraded the day it went live and for a while we had 67Mb but now it is 48Mb, not too worried about that as only two of us in the house now and we can both stream video without problems. It is likely that our consumption of speed will grow even if we are reluctant adopters of the latest tech offerings.
|Thread: Anyone recognise this mains connector ?|
this German supplier still makes these plugs, there is a silicon version to stand 200°C. They are linked to at the bottom of Michaels link.
+1 for old style kettle and coffee maker type equipment. Unless you really want to keep it original I would go with Emgee and hard wire it or fit a modern euro style connector, be aware there is a hot condition version with an extra notch for kettles but the regular version is rated at 6A which would be ok for the 900W load you have.
|Thread: R8 spindle advice required|
My VMC has a pin and it is probably only useful for the initial insertion and running down the drawbar, once the drawbar starts to tighten then the taper provides all the friction needed to stop the collet turning.
|Thread: Cleaning a straightedge|
The scourers for not stick pans and baths are non abrasive, these usually seem to be white and the abrasive type seem to be green. The white seem good for getting flies off windscreens and even paint without an harm to glass or paint, not bad on alloy wheels if they are painted type.
|Thread: "I'm calling about your accident" - how does this scam work?|
I just asked them if that was the one my wife and children were killed in, it went a bit quiet at the other end, I let him off the hook after a few moment of sweat.
|Thread: not tightening|
Just to be pedantic BA is a metric thread but your nut and bolt will need to be a match.
|Thread: DIY magnetic DRO|
You are dead right about crimping Clive but a bit of preparation can make the solder bucket version much less painful, many years ago I made a heavy block with tapped holes for various d-sub plugs, I then tin all the holes and ends of the wires after a light twist to stop any stray strands. A quick touch with a fine point iron and a nice bright secure joint with no bridging to adjacent pins should be achieved. Getting the cable cores the right length will help, too short makes life difficult and too long will leave a lot of cable to try and stuff in the shell. I don’t usually sleeve but I try to minimise any bare cable and not use cable that is too big. It’s always worked for me.
|Thread: Making from castings or scratch build.|
Are you proposing to make your own patterns and castings or machine from solid and fabricate? Some ready made castings can be a bit tight on machining allowances and need a good think before cutting metal.
