I'd thought that eBay had changed the rules on feedback a while ago to the effect that feedback couldn't be subsequently changed.

Not true?

... complete with macrons too (coincidentally been learning about those somewhere else recently).

I've always undercut the shaft when using epoxy. Without that, I don't think you could get sufficient bond-line at all, for any sensible shaft fit.

Don't forget that you may be able to undercut the shaft along part of it's length by a few thou (or whatever) to give you any gap that you need while maintaining its fit where it's needed.

Given the almost overwhelming UK-centricity of this site, I think it's a little obvious.

As for profiles ... topic done to death already.

Probably on this side at a guess.

Actually there are two answers:

1. This didn't come out of the blue like a massive meteorite hitting the Earth (predictable but only in long time frame). A pandemic was both predictable and predicted in a short-term (few decades) time frame. As such, governments had a duty to prepare for it. Instead they were completely caught on the wrong foot and unprepared.

Pre-ordained emergency plans should have been drawn up years ago instead of the mishmash of hastily conceived ideas that we've had foisted on us. At the very least, as soon as it became obvious that something was afoot, there should have been plans to immediately halt all international travel while they stood back and assessed the situation.

IMO the lack of action in the preceding years amounts to criminal liability for thousands of (avoidable) deaths.

2. I couldn't build a brick wall so I'd employ a professional bricklayer to do so. He would charge me accordingly. If the wall falls down is any bystander legitimately able to say "could you do any better?"

Hopper, You really think that the fact that it should be obvious to anyone with any experience (what about those without, perhaps younger people?) justifies not bringing to eBay's attention a deliberate attempt to deceive?

If the false description doesn't do it, look at the eBay picture close up and see the deliberate fake up.

If you copy the picture from the eBay ad into a half-decent graphics program where you can enlarge it , it looks a lot more like "Mitutoyo" than "Mitetoyo".

Why complicate it? Paul Rhodes above has the best idea. just calculate what proportion of the bag is need for your lawn and spread that. (It ain't critical - you can eyeball that much).

I think I've spent 90% of my 3D printer activity on making experiments and 10% on making anything useful.

Around here (Southern Ontario) the gasoline prices dropped (from ~$1.20 / litre) to $0.65 -0.75 some weeks ago. It's now rising again (perhaps 0.75 - 0.85 / litre).

This at a time when the Globe and Mail is reporting that the price of crude from the producers has gone negative (i.e. it's piling up and they are paying people to take it away).

Ah, I see. That old adjective "ironic" - always miss that.

My apologies, Colin ... it wasn't obvious to me.

.... yet would it be economically viable to do so?

What I think ought to be possible - probably need Adobe to do it - is to have a pdf that will "lock" itself to the machine that it is downloaded to and refuse to open on any other.

Hey, computers can do anything with the right programming can't they?

I've never gone the CNC route but I have had a stepper motor connected to the leadscrew for other purposes and the (lumpy) drag from the stepper when manually feeding was very noticeable and pretty much killed any "tactile feedback". I certainly didn't like it.

Moreover, at the time there was concern in some quarters (refuted in others - this is the internet after all) that back-driving the stepper while it's still connected to its driving electronics is a bad thing to do because of generated voltages. Dunno personally - bit beyond my pay grade.

They (F1.com) ran a Chinese GP simulation today with thje following driver lineup:

Not something I have any serious experience with but surely it's possible to do "manual" control using gcode segments? That is, drive, say, the x-axis at such and such a speed until terminated.

etc

It should be possible to compose a whole toolbox of gcode segments for manual use. In fact I'd be a bit surprised if someone hasn't already done that .... a simple control panel with manual commands.

Or am I all wet?

When I saw this, I was just about to post to the effect that to me it would be a no-brainer. A sufficient subset of the correct taps/dies is not really that expensive in the scheme of things and to me would totally outweigh the hassle involved in switching threads.

Different strokes for different folks of course. (it also helps if you are on this side of the pond where UNC/F is ubiquitous ).

Has anyone seen any of the Formula-1 Virtual GPs such as this.

This is absolutely mind-numbing to me - I had no idea the simulations were this good these days. Especially when, as i understand it, the drivers are all sitting in their own homes, not at some central location.
