|Thread: Will cash become obsolete ?|
I suspect drug dealers wouldn't be too bothered, as cash is easier to find, trace and confiscate than bitcoin, and there seems to be no shortage of people willing to act as money mules, accepting and passing on bank transfers to obscure their origins.
|Thread: EMI from electric shavers etc|
Is this the best place to find this information Sam? My guess (and it is just a guess) is that there will be more variation in the sensitivity of different types of medical device than different brands of shaver. Perhaps the device (medical, not shaver) manufacturer, the hospital that carried out the procedure or the British Heart Foundation (who have a leaflet which includes recommended separation from different electrical devices) may be much better placed to advise you.
|Thread: Warco WM280V-F Gearbox|
My son's Chester has a similar (identical) gearbox and the warning at the top left is enough to stop me trying to change gears when moving, especially as it is his machine and may have to last another 60 years. No problems changing gear when stationary as long as I turn the output coupling whilst moving the lever.
|Thread: QCTP dilema?|
I'm reasonably happy with the (Aloris copy) piston type but should we change to the wedge type we won't need to buy new toolholders as both take the same type.
One thing to consider is whether your compound slide is flat-topped or there is a spigot on which the 4-way is mounted. If there is a spigot it is easy to machine the piston type to fit over it, but for a wedge type you will need to either remove the spigot completely or do as I have done and machine it down to fit the toolpost. I managed to do this on the mill, but otherwise you would need access to another lathe or a raising block for the 4-way (which could perhaps then be re-used as a rear toolpost).
|Thread: Exhibitions 2020|
This weekend's (21-22 March) "London Festival of Railway Modelling" at the Alexandra Palace has been cancelled **LINK** as has the National Garden Railway Show (04-April) at Peterborough although the association hope to reschedule for later in the year. **LINK**
Not directly model engineering related, but some users of this site may have planned to go.
|Thread: DVLA Scam|
Similar "intermediary" websites exist for everything from driving tests and passports to parcel tracking, and they often appear before the real thing on searches. Unlike the "your renewal payment failed" emails, these are completely legal (if morally dubious) "services" as long as somewhere on the site they state that they are not the official websites. To quote Tom Waits "The large print giveth and the small print taketh away".
|Thread: Archive on Pocketmags|
Are there any plans to migrate the archive to another format before Flash support ends or will we lose access to the older issues at the end of the year?
|Thread: Coal being phased out|
Thanks to the services of certain online markets, electrode heaters as shown in this video are readily available.
We may have had less types of light bulb, but we made up for it with six different non-interchangeable domestic power plugs (two pin and three pin in 2A, 5A and 15A sizes). Plus of course that bayonet plug that fitted into a bulb holder, a hangover from the days before electricity meters when consumers were charged per light fitting or socket, and the proprietary (and expensive) plugs needed for council houses with non-standard sockets.
People would go to extreme lengths to keep the bill down, many years ago, when my father was asked to wire a house for the first time he was told not to put a light fitting in the front bedroom as there was a lamp post outside.
|Thread: Unimat SL Circular Saw Arbour|
Might be worth posting the same query on Unimat@groups.io the successor to the old Yahoo group.
I've failed to find a photo I once saw on the web of a loco (Simplex?) with an elongated tray fitted to the eccentric strap, funnelling oil from a drip feed into an oil hole. It took me a while to work out why the loco had four pipes from the oil box on one side and three on the other.
|Thread: 3D Scanning, Anyone?|
Take a look at Meshroom. It is free and uses photogrammetry to produce a model from (many) photographs taken with a phone or digital camera. The workflow is pretty simple and the results of the tests I have made impressed me.
The only real issue is that it is processed on CUDA cores, and therefore requires an Nvidia graphics card. I had to swap my AMD card for a pair of GTX760s from my son's PC to run it at all, and even with 2300 cores and 8GB of video RAM it still took nearly an hour to create a model from 40 x 8MP images, so I would suggest that is about the minimum spec and that a modern card (the 760s are six years old and are only CUDA 3.0) would be better.
|Thread: Metric V Imperial Measurement|
First class stirring.
I love the fact that there is no longer any connection between the BSP/G size and that of the pipe. It shows that sometimes practicality is allowed to override order.
|Thread: Digital verniers|
Could it be a patternmaker's shrink rule?
Is it time to accept that our language has changed over time, and accept that these sophisticated (but in which meaning?) calipers are called "verniers"? We could always go back to an older usage, still used in German, and call the Vernier scale a "nonius".
Perhaps we could then turn on Mitutoyo who use the term "Digital Micrometer" to describe their QuickMike, despite it using a linear scale instead of a micrometer thread? Should however Mitutoyo decide to give me one of these instruments, I would happily use the same argument in their defence
|Thread: Desoldering how to?|
Has anybody tried stainless steel desoldering tubes? I ordered a set after seeing them described (but not used) on YouTube, but haven't had occasion to use them yet. The idea is that the solder is melted and the tube slid over the component wire. The solder doesn't stick to the tube, so when it solidifies the tube can be pulled out, leaving the component wire loose and a hold in the PCB.
(Edit, found a video showing use)

|Thread: Moving a Sieg SX3 Mill|
My son and I moved his Sieg X2.7l upstairs in 3 main pieces, the head was probably the lightest after we removed the belt cover and motor to get to the securing bolts. He ended up doing most of the lifting on his own as my paralysis kicked in half way through but the base with the (long) table was definitely a two man job. Photographs of the connections and adding numbered labels to each wire as it was disconnected helped. Unless you have access to the rear it is useful to have a smooth surface on the bench so it can be spun around during assembly.
|Thread: Back plunger indicators - does anyone use them?|
I nearly bought one at Christmas (Amazon had some seriously silly price reductions of 75% or more) thinking the "see-saw" deep hole attachment looked handy but in the end went for a vertical dial DTI which, like the back plunger indicator, can also be read in any position on the mill. I have to say though, US made Starrett kit always looks and feels lovely, especially in the padded jewellery boxes.
|Thread: Arc Euro Trade website down|
I suspect a very long time, as it is difficult to imagine the web going down permanently unless the physical structure of the internet was destroyed, in which case the collapse of the financial system and complete stoppage of communication and international trade would probably reduce us to a barter economy. Assuming of course that we weren't wiped out by whatever disaster ("dinosaur killer" meteorite, global nuclear war, pandemic?) caused the failure in the first place.
Sorry, I'm operating in "little ray of sunshine" mode this afternoon.
|Thread: The blind leading the blind|
Not the first time, and certainly not the last, but I suppose we should be glad the subject of this famous photo is wearing safety glasses.
