⌘+c then ⌘+v

Russell

ctrl+c, ctrl+v, and ctrl+x (cut) should work on text in any program running in a graphical environment such as windows, or X in Linux.  It doesn't work at command line level where ctrl+c is used to abort the running program. On MAC the ctrl key has a strange symbol, a sort of square with circles at the corners.

Hope that helps.

I get the same on the Firefox browser if I use the paste button on the context menu. Holding down the ctrl key on the keyboard while pressing the v key works just fine. That is an operating system function and bypasses the browser functions.

Can you still buy "Savbit" copper bearing solder to stop the bit disolving?

P.S: To answer my own question, CPC list it and it is still a tin/lead alloy.

Are you considering upgrading to cnc? If not I wouldn't fit ball screws as they will not stop the slide moving under load. They are reversible unlike normal lead screws.

As I understand it the problem with single phase motors isn't the slip but the cyclic variation in torque with the rotation. It has nothing to do with the speed. A three phase motor produces a much more even torque. It's a bit like the difference between a two cylinder engine and a six cylinder one.

I've replaced the single phase motor on my lathe with a three phase motor and inverter and get a noticeable improvement in the surface finish I can achieve as a result. A DC motor should give a similar improvement.

Abbey Blue Gel works well for me. OK, it's for blueing but three or four applications gives a deep black. Only about £8 on ebay.

I degrease with nothing special - just isopropyl alcohol.

Well, here in France, where the metric system was invented, all threaded pipe fittings for domestic use, including taps etc., are BSP but sold by the thread diameter in the nearest whole number of mm.

Sorry if I offended you Howard. Just pointing out an amusing ambiguity in the French language. "Je vis" can mean "I live" and also "I screw".

Russell

Do you live alone or screw alone

Earlier versions such as MS-DOS 1.25 (also known as PC-DOS 1.1) came on a single 5 1/4 in floppy disk.

The OS on the first computer I used, an Elliot 803, came on a punched tape.  On second thoughts it was probably a boot loader which we followed by an ALGOL compiler also on paper tape.  Modern PCs are definately an improvement.

The recommended minimum requirements for Linux Mint are 2 GB memory and 20 GB disk space so Peter should have no problem running it on his laptop. However if he wishes to buy a new one it would be a good idea to check on the Mint forum to see if anyone has problems with his chosen model. It's worth buying from a supplier who will take returns without question if it's not suitable. My present laptop was bought from CDiscount in France. The first one came with Windows and I set it up to dual boot with Linux but unfortunately the graphics chip was not supported in the Linux kernel at that time and it would only run slowly with software rendering. So returned it (carriage paid by the supplier) for a full refund and bought a slightly different model with a different graphics chip. I believe Amazon will also accept returns of unsuitable product very readily.

It could well be that you are running out of space on the root partition of your hard disk. Have you had a look at your disk with the built in Disk Usage Analyser program? It is easy for old files to build up.

There is an old thread on disk testing on the Linux Mint forum:

I am running Linux Mint 19.3 on my laptop and have only 17 GiB used in the 40 GiB root partition. I have a separate partition for the /home directory which does need clearing out occasionally but is currently up to 75 GiB. Linux does need very little disk space compared to Windows unless you are going to do things like run virtual machines in Virtualbox.

I rarely use Windows but had my desktop computer set up to dual boot with Linux and Windows 7 pro, primarily so that I could run Fusion 360 and a few other odd programs that would only run in Windows. Being concerned that Autodesk are likely to withdraw Windows 7 support for Fusion I decided that I had better upgrade to Windows 10 before it is too late.

To start with I made a backup of all personal files on the Windows and Linux installations.

Next I downloaded and ran the Windows upgrade .exe file, being careful to choose to keep all the files on my system. The first problem was that the upgrade program told me that I hadn't enough free space on the Windows partition of my primary solid state disk. Fortunately I had some unallocated space on the disk but it was at the end of the disk and my Linux/ partition was in the way between that and the Windows partition.

So, abort the upgrade, boot the computer from a Linux live disk and use gparted to move the Linux partition and expand the Windows one into the newly freed up space. Rebooted and everything seemed to be OK.

I tried running the upgrade program again. This time it seemed to be going OK but after the first of the restarts it performed the computer wouldn' boot at all, neither into Windows or Linux. It just displayed this:

error: unknown filesystem.  
grub rescue>

After a bit of internet research I managed to boot into Linux. I then installed a program called boot-repair and ran it. That restored my Grub boot system and I was then able to continue the upgrade which, after several more restarts seems to be working fine. I now have a fully activated Windows 10 pro and Fusion 360 is working fine.

Welcome to the club David! Us old gits must stick together.

+1 for the Harold Hall T & C grinding jig. I made one years ago and it does everything I need.

Are you sure the o-ring is 1.5 mm cross section? The nearest UK standard size would be 1.6 mm. Tubal Cain recommends (in his Model Engineer's Handbook) a groove width of 2.3 to 2.5 mm and depth of 1.18 to 1.25 mm. The width is greater than the ring cross section to allow for the compression of the ring. I would start at the tighter end of the tolerances, try it, and adjust to get a good feel for the fit. Yes, silicone is good.

Even more confusing, current French uses "Soudage" for soft soldering, silver soldering, and welding. The French term "brazage" refers to using a brass (laiton) filler.

The flywheel fits to the crankshaft by a short taper. You can turn a matching taper in the lathe with a short threaded section for a holding nut. Fit the flywheel to that and it will run true and should turn easily.
