"Nonetheless, provided you know what you're doing, command line methods often faster to invoke and more efficient in operation."
Agreed Dave. When I first started using Linux (in the mid 1990s with Red Hat Linux) I spent many happy hours with the manuals and still occasionally refer to Blum's 800 page "Linux Command Line and Shell Scripting Bible".
Not sure that's the easiest way for beginners! Yes Imagemagick is a very versatile bit of software but is command line only. Perhaps an easier way would be to install Converscreen which acts as a graphical front end ti Imagemagick and will convert and resize almost any image format. Even works on Windows as well!

"My pics are usually from text with .odt from LibreOffice but I can convert them to .docx or .bmp easily.
Install Xviewer which can be used to view a number of formats and you can save from it in .jpg format.

If the surfaces are good don't use any gunge at all. If it's really necessary try Hylomar Blue which was developed by Rolls Royce.
|Thread: Windows for the scrap bin?|
I agree that Windows updates are a pain. Linux updates in the background while you are using it, in most cases no need to reboot.
I have both Windows and Linux on both my laptop and desktop machines and rarely use Windows - just for Fusion 360. I find Linux is faster, more secure, and more reliable. Give it a go.

|Thread: Identifying brass?|
If it came from a sea going vessel it would not be brass or Admiralty brass. Neither is suitable for continuous immersion in sea water due to the high proportion of zinc. Zinc is used for sacrificial anodes to prevent corrosion of other metals in sea water. You should see what they look like after a couple of years at sea§*!
|Thread: countersink advice|
It's best to modify twist drills to give zero rake to the cutting edge for working on brass, even for small sizes. It gives a much better finish. The modification process is very simple, see here:
|Thread: Antikythera solved ?|
Those animations are brilliant. I can't imagine how anyone managed to create something like that 2000 years ago.
Aliens? Time travelers?

|Thread: Ball Races and 'Brinelling' (whatever that is).|
Well, I used miniature stainless steel ball races with all the lubricant washed out on the pallet arbor of my regulator clock and it has been running for about five years with no problems. The pallets only rotate by about 20° but of course the load is very low as is the speed. They have oscillated through about 80 million cycles though.
|Thread: Junior hacksaw blades|
The main advantage of fitting the blade so that it cuts on the pull stroke is that, if it sticks the couple tends to lift the blade rather than causing it to dig in.
|Thread: ME beam engine|
+1 for reeves. I bought the casting set for the beam engine "Mary" many years ago and found the castings to be good quality.
|Thread: Antikythera Mechanism : New-ish findings|
Some time ago I found a Solidworks 3D model of the Antikythera and managed to translate it so that anyone who uses Onshape (free) can access it here:
Hope that works.

|Thread: Ultra sonic cleaning|
I have found that dishwasher rinse aid is preferable to washing up liquid as it is a non foaming detergent. However my main machine is almost permanently fille with clock cleaning liquid to this recipe:
Brass parts in particular come out bright and shiny.

|Thread: From UK or Germany delivery|
Yes, so much for "free trade" after Brexit. We have similar problems buying from UK suppliers for delivery here in France. Carriers are demanding exhorbitant fees for customs and VAT before they will deliver goods that I order.
|Thread: Hey you! What lathe? Why?|
I bought my first lathe in the 1970s for £50; It was an Edgar 5in model from the 1920s. It came with a motor to replace the treadle and I used it for a few years for the restoration of a vintage car making things like shackle pins and skimming brake drums. Later I replaced it with a UK made clone of the Atlas 10F from about 1950. I initially used it for vintage car work and later for model making, clock making, and (for brownie points) for household repairs. It is like a slightly bigger brother to the Myford being of similar design.
For a while I had a far eastern 9x20 lathe as well but needed the room for a milling machine so one of the lathes had to go and I chose to keep the Atlas which is still in use.
If I was going to replace it I would go for a new Chinese lathe.

Another good French online supplier:
Hope that helps

|Thread: Washers under nuts|
There are some circumstances ahere a washer should NOT be used. For example, if both the bolt and the surface it's fitted to are hardened an normal soft washer will reduce the reliability.
