This one seems to be a bit different, the Budapest Cog-wheel Railway, is a rack railway in the Buda hills part of Budapest. It connects a lower terminus at Városmajor and with an upper terminus at Széchenyihegy. The line is integrated into the city's public transport system as tram line number 60, is 3.7 kilometres (2.3 mi) in length, rising some 264m.

Coming into the station.

The rack

The drive system consist of a single rack and wheel. It uses the Strub cog-wheel system. (the link is to Wikipedia) The wheel & rack display seems to have a slightly different construction to that actually fitted between the rails (might be an earlier version)

Detailed instructions on doing a factory reset can be found here *** Samsung Factory Reset ***

Odin is not the most user friendly of programs. Not recommended unless you know what you are doing. It is quite possible and relatively easy to 'brick' the tablet without trying, assuming it is not already in this state. You are playing with things not usually encountered by tablet or phone users. This is deep into nerd land. I have done it to install custom ROMs on phones but would not recommend it to a basic user.

John

Harry, I too have a Samsung Android tablet. It regularly updates itself, downloads the data when connected to wifi and not doing anything else and then installs the update. Looking at the other part of the message on the screen it would seem that it has crashed during an update. The download could have been corrupted (it should check that) or it has just missed a beat if the cable was pulled at the wrong moment.

The long press on the Volume down and power button at the same time should (in theory) induce a factory reset mode. There are other combinations of button presses that do similar depends slightly on which model. It is possible to reload the factory software but it requires extra software and a lot of patience

John

Not quite dead this error is typically encountered when trying to flash a non stock ROM onto a device. Unless you are into DIY custom ROMs I doubt there is a simple fix. You could try just pressing Volume Down and Power button, until the tablet restarts this could take several seconds of holding definitely more than 7 seconds.

If that doesn't nudge it back to life it's to the Samsung shop I'm afraid.

Mine is not the same model but the various 'ends' are fitted separately:-

Torch on left next is the soldering head with bit then torch and the bit at the top slides onto the torch and makes a mini hot air gun.

When lit the soldering iron looks like this. Looking at yours I am guessing that the 'corrugated' bit of the nozzle comes either unscrews or pulls off before the soldering attachment is screwed onto the black collar

Hope that helps a bit.

Just to be clear the video is by LMS4767 not me it is rather good though.

John

You are most welcome.

I have also added the YouTube Video as a link at the bottom of the post together with a link to the results of the competition.

For anyone who who missed the show I have put up some images and a bit of info.

See *** Midlands MEX 2022 ***

Enjoy

I use these:

It is indeed one of the many variations of a 'roofing hook bolt' see here *** Fixfast Skills Hub ***

John

Was indeed rather good, missed the makers name though. Was attracting lots of attention and comment.

John

Yes very fine workmanship, not a good photo but I believe this is the item for others who haven't seen it.

John

Noel, you were missed!

Before moving the headstock it may be wise to first eliminate any other possible cause of run-out.

• On a lathe that old are you sure that the MT3 socket in the spindle is clean and straight, has someone tried to clean it up and put it out of kilter with the spindle.
• Has the lathe been set up so that there is no twist to the bed which could account for the non parallel turning.
• Is the MT socket clean.
• How accurate is the test bar and is that clean and undamaged.

Moving the headstock should be a last resort this is 'Here Be Dragons' territory.

Move slowly and carefully, eliminate all other possibilities before unbolting the headstock.

There are of course alternative ways of making the screw captive, not better, just different.

Anyone contemplating making toolmakers clamps my *** webpage *** might help. Harold Hall's website has plenty of useful information on toolmakers clamps complete with drawings, suggested sizes and different styles, well worth a look: Workshop Projects - Toolmakers Clamps.

John

Be aware with ISO 30 taper tooling that there are several different variations on a theme. They all use the same angle and power is transmitted by the drive dogs, not the taper. There are however different arrangements of the drive dogs and different draw bar threads. viz-

• ISO, NT, NMTB, DIN2080 - short parallel section at small end. Equal drive slots.
• CAT, CV, V-Flange, DIN 69871 - no parallel section. Unequal drive slots.
• BT, MAS403, DIN6383 - no parallel section. Equal drive slots.

Care needs to be taken when purchasing particularly is 2nd hand from relatively unknown sources.
