John,

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

Thank you for that enjoyable report and photographs. It almost makes me feel like I was there.

Ches

ega, Circlip,

Yup.

I know spell check & post number was mentioned earlier on but if enough call for it then who knows...maybe a Poll is required?

In order of usefulness (to me) ...

1) Spell check, as I type

2) Post numbering eg #123

3) Use mouse for Cut and Paste rather than KB shortcuts

4) Ability to keep an archive list of useful (numbered) posts. Currently I can bookmark that entie page in my browser (Firefox) but that gets a bit messy - I'd rather have a corner of the ME site where I can keep listed all my favourite/useful posts.. This may also give the Moderators an idea of what topics float our boats

David,

Yes, there seems to be a subtle improvement on the photography and it's formatting/layout.

I just did a quick scan of Iss 320 and superficially there doesn't seem that much difference, but Iss 321 photographs are more 'on message' .... ie they are more tightly cropped to the item under discussion meaning less distraction and a better close-up view.

And maybe the Ads are now positioned more to the start and end of the magazine rather than appearing mid-flow, which I find less distracting. That's not to say I don't like the ads but it's easier to find them at the mag start or end rather than dotted about the middle.

Just received the November 2022 issue through the letterbox.

After a quick scan through, it seems to me that the photography and picture selction has really improved. It appears that the Editor's Bench intro regarding the aim for better overall picture quality has worked.

My own preference is that each set of pictures tells the story, even if no words were added, the pictures are numbered (and referred by number in the text) and each picture has a title/description in or under it - as is evident in most of the Nov issue's articles.

Occasionally I feel that some articles might benefit from a hand drawn (or CAD) assembly drawing as a starting point to explain the project at hand, but apart from that ...very well done.

Regards,

Ches

Jason,

There are a number of German ME suppliers,

Thank you for that detailed response. I have had a quick look through the links....will spend more time later today

Ches

Excellent. Thanks for posting and thanks to the cameraperson.

appeared to be quite a few youngsters there which can’t be bad.

Yes, the (mostly?) German visitors seemed to be at least a generation younger than those on other similar videos I've seen from the UK and USA.

There were some fascinating models there. I wonder where the Germans get their supplies/drawings/kits etc from?

Ches

Edit: 'generation younger' - I've just watched some other YT videos on the show and see that there was a very wide cross section of modelling types eg RC construction vehicles, model railways, steam punk dragons etc...so there is maybe more to pull in the younger visitors?

Not a model from the past but one from a possible future where a company is trying to model a human ...

'Tesla AI Day 2022' (3 1/2 hrs long) ... https://www.youtube.com/watch?v=ODSJsviD_SU

Not a slick Jobs/Cook type presentation ... Musk doesn't do those.

But what an insight in to the engineering challenges, and a carrot for young engineers looking for an amazing career.

No change in thickness of the sheet of paper

Ah, that's the answer

if you folded a sheet of paper in half 42 times would its thickness be more or less than …………..

Less than three times the paper's thickness. Fold the paper in half, open it out, fold it in half again etc etc. It will always end up twice it's thickness.

The Q says the 'sheet of paper' is folded, not the folded sheet is folded.

This looks to be such an exact copy of the Noga, how do they get away with it?

AFAIK, Amazon doesn't care two hoots about whether the goods they sell are fake, rip-offs, 3rd rate copies etc...as long as Amazon makes some money off them all is fine in Amazon world.

And as for importing these fake goods in to the West, I believe it is the Importer that has to ensure the goods are bona fide, not the local Customs agency. And Importers are notoriously difficult to track down and punish ... they have developed stealth and evasion techniques that the Western military would be proud off.

Oh, and Western Governments seemingly couldn't care less either ...it's almost as if they have been bought off, which of course could never happen.

What is the answer to all this...I think we let that genie out the bottle too long ago to get him back in.

David, John,

Thank you for the ideas. I'll have a look at them.

Andrew's suggestion has solved my immediate need but I'm always keen to hear opinions.

Ches

Jason,

I've already drilled and tapped the holes at 7BA. However I'm using 'one size down' hex head screws so they look OK. But you are right, 10BA would have been even better...next time

Andrew's idea worked a treat ...two bits of metal with a hole drilled through both and the brass clamped between. I'll also have a test go at using MDF+clamp.

Ches

Andrew,

Thanks. I had thought of that but wondered if there was an easier (ie lazier ) way of doing it. I'll probably give your suggestion a go though.

Ches.

Hi all,

I'm finishing off the build of a Stuart Beam and need to put a fixing hole in each end of the two brass cylinder-lagging bands.

Hole size is 7BA clearance ie about 2.55mm or so.

The medium hard brass banding is 0.5mm x 5mm

Ideally I'd like to use something like 'leather belt hole pliers' but suitable for brass and with a selection of punches - say, 1mm dia to 4mm dia.

I've tried drilling but, as expected, it tends to make a bit of a mess. I could drill a 1mm hole and open it out with a needle file but that takes time, and I do like to find the quickest, simplest way forward

Regards,

Ches

As ega says ...

Oil-tempered hardboard or good quality lino and renew the edging.

During the training days of my youth our benches had a 4 mm (appx) thick layer of grey lino type material. Every few years the 'lino chap' would call in and replace all the bench tops with new lino.

My current workshop uses a layer of hardboard pinned to the bench, plus some edge trim that sits flush with the top of the hardboard.. The hardboard is cut in to sections (by B&Q) so that the high usage areas are easily lifted and replaced.

swinging a 5 foot plate

That must have been quite a thing. Was there a counterweight, or was the cutting speed low enough that one wasn't needed?

Ches

David, Yes, I occasionally worked on larger machines in my youth...the big mills I was fine with, but the big lathes I was very wary off.

Sean, Kurt seems one of these motivated people that gets things done. I'm curious to see where/how the block fits into the Borer. I imagine the original designers of the Borer did their stress calcs on all bolted interfaces...I hope the riser lasts the course...it certainly looks substantial.

Ches.

Not exactly home workshop equipment but an interesting insight in to how the 300 mm high block was made (out of 20 mm plate), welded and skimmed.... https://www.youtube.com/watch?v=roMzviZ4p6I

That's a heck of a parting off tool!

Part II (the installation) to follow soon, I believe.

Ches

There's quite a few links in here that may lead to some (fairly) local model engineering enthusiasts ... http://www.hrsoc.org.uk/Links.html

Or maybe contact 'Bridge of Brown Crafts in Elgin to seek their advice ... http://www.bridgeofbrowncrafts.co.uk/
