No, the boxes are what they keep the drills in.

I'll leave now.

Me neither - but I only use cutting fluids/coolants that are intended for the job. I never use the oft-recommended (here) WD40 since I can find no evidence that it's intended for that job and the MSDS makes no mention of it. Who knows what by-products are generated if it gets hot? (Not to mention it stinks).

About as good as driverless cars - and the same kind of wishful thinking.

Has anyone tried asking these things "what is the interval between the birth of suckers?"?

Just to point out that the article mentioned "wrong data" which is not necessarily synonymous with "error" (as in misteak).

As a - perhaps rather contrived - example: if it was know that the antenna pointing was drifting it might not necessarily be obvious in which direction. You could then send a signal to inch it left or right and see if the signal strengthens or weakens. That might be a coin-toss at that point and there is a 50/50 chance of sending the wrong data. You could lose it at that point if it was on the edge of signal loss anyway.

Also lets not forget that this spacecraft is way (way, way) beyond its design life. It has long since repaid its investment; power is limited and much of the onboard technology has been shut down. Minimal funds are being provided to keep this going and only then because of a lot of lobbying by a few interested parties. It's more a question of when not if it's going to quit.

They're not really separable. You don't necessarily want to do a reset simply because it's scheduled on Jan 5 (or whatever) if at that time the spacecraft is functioning as expected and you have good communications. It won't achieve anything and actually represents a risk.

SOP for spacecraft (near and far) pretty much from day 1: if you haven't heard from us for xxx, do a reset of the communication system (and perhaps some other things).

If you still don't hear from us there's this bunch of other stuff ...

... not to mention that if the friction (bearings and writing point) is too low you won't get those nice harmonograph patterns. It'll just keep scribing the same path over and over.

Go here and download the March 1952 edition of Practical Mechanics (and any others that take you fancy). It was also published in one of the (two) Practical Mechanics How to Make it Books.

Just my luck - won't ship to Canada. Almost had me there.

This is the 2020's - workshop gremlins have phones these days!

(fwiw, Amazon has a whole bunch of smart label products).

So that's where my hair went - always thought the scorch marks were a bit suspicious.

Very interesting link - thanks, Michael.

perhaps quite cheaply if they realise you have no way to accurately check it!

I would definitely check that. Their website that Ron linked to is quite clear:

"Slicing Software: Creality Print; compatible with Cura, Simplify3D, PrusaSlicer"

If you have a cookie manager you could try deleting any cookies associated with Facebook. (I hesitate to suggest deleting all cookies - as is often suggested - because it can cause other problems).

What happens if you hit the "Close" bar at the bottom?

For smallish parts, you may find a heat-shrink-tubing gun quicker and more efficient to do the heating bit.

(My first post on this disappeared too).

At least with things like bread and milk non-concerned people have a choice.

Not so with Rowntrees (fruit pastilles and others)... and they're predictably awful. All to get a substitute for gelatin which comes from cows (not Cowes, that's IOW).

(I thought cows were vegetarian anyway).

It looks like an aeroplane that's intended to fly .... not like something that ought to drop out of the sky.

If you have to do it with a slot drill, I'd at least sneak up on it with several smaller slot (or regular) drills first.

I'd be inclined to turn and bore the whole thing on the end of a piece of brass bar then part or hacksaw off and face the other side (could be held by the axle).

Another source for useful bits and bobs (if you can find something similar closer to home).

... or it may be more prosaic. They computer-generate combinations/permutations of names they pick up anywhere on the internet (here for instance).

So for example if they see "Harry Wilkes" here they might generate [email protected] (and hotmail.com and ...); Wilkes@ ... ; HarryW@.... etc. Most of these will go nowhere but some may hit someone.

I wouldn't over-think it.
