|Thread: Leveling machines|
Levelling your lathe won't make it more accurate.
It may make it easier to set it up to work its best, but not being completely level won't stop you setting up a lathe.
You might be able to set your lathe perfectly level then find you have to slightly twist the bed to achieve parallel turning.
There is an identical debate around levelling the tripods on which we place equatorial telescope mounts. If the tripod is level each time, it's arguably quicker to set up, but once the mount axis is aligned with the Earth's axis the orientation of the tripod is irrelevant.
|Thread: Silver Solder Stocks|
I assume that as with jewellery the status of anything made before 2011 will be it has to be 'safe' (without any clear qualifications).
As for 'new old stock' for brazing rods, it's illegal for us to use them, so I can't understand why selling them would be OK.
It might be worth thinking about the legal status of models and locomotive boilers made with cadmium bearing solder.
If you want to sell an item made post 2011, you would be wise to avoid all cadmium containing materials.
|Thread: Centre Drill Leaves a “Pip” - Sometimes|
In the past, most people would only have had access to jobbers' drills and centre drills.
It made sense to use a small centre drill to create a depression into which a larger jobbers' drill would fit.
Collectively, the hobby got into the habit of using the tip of a centre drill to spot for small drill sizes, because it usually works but the risk of snapping the tip is high.
Spotting drills cast no more than centre drills, so the first time you avoid snapping a centre drill the cost is saved.
Alternatively they can be ground from broken longer drills, just use a slightly more acute tip angle.
|Thread: MEW 306|
People will notice a pagination error for Jacques Maurel's Universal Vice, with page 53 being repeated.
Two people have reported different pagination errors with the article affecting pages 55 and/or 57.
We are a looking into what happened.
Less significantly, Panel Punch took more space than expected and was not marked as 'to be continued',
The final parts of both articles will appear in MEW 307.
My apologies for any inconvenience.

|Thread: MMEX 2021 Cancelled|
I've just had the above notice from Meridienne Exhibitions.
Cancellation of 2021 Midlands Model Engineering Exhibition.
It is with deep regret that due to the ongoing uncertainties of Covid-19 pandemic; we have to announce the cancellation of the 2021 Midlands Model Engineering Exhibition which was due to be held at the Warwickshire Event Centre on the 14th-17th October.
This difficult decision is taken despite a real determination by the Meridienne Exhibitions team, trade, clubs, societies, exhibitors and other supporters, all striving to continue to deliver the usual high quality and successful event during this very difficult time.

|Thread: Mystery micrometer|
They are both Tube micrometers.
More usually they are just a normal mike with a cylindrical anvil.
These appear made for inspection purposes mounted in a stand.
|Thread: Making a miniature electric bell|
A twin coil bell should be easy enough and able to do the job.
Just google miniature solenoid if you don't want to wind your own coil and use two side by side. You can put a dummy pole piece across their base.
|Thread: The last Gravity Ropeway|
Fascinating, but I agree it's not very failsafe if you want to carry people!
|Thread: Tool post height|
Says it all really
|Thread: Beginers telescope|
if you want to do visual astronomy, look at the 'beginners telescopes section at First Light optics.
Because there are bright objects you can start on a first scope need not be huge, and looking at relatively easy targets like the moon, planets and bright deep sky objects will give you a better idea of how you might want to progress, rather than blowing a fortune on an expensive scope that will probably be specialised in its application.
|Thread: Uncertainty of Measurement [Global Warming]|
I think the thing that the Canada heat bubble has thrown into sharp perspective is the way that although 'weather is not climate', underlying changes in climate make extremes more extreme, and in particular how more energy in a chaotic system can make it more active in unpredictable ways.
As for the impact of 1.6 degrees, 2 degrees is the typical temperature drop from going up a 1000-foot mountain. Anyone familiar with the UK landscape will know farming and vegetation can be very different just 1000 feet up.
|Thread: Change Wheel Programme from MEW|
And the only computer language that irreparably damages the user's brain is F0RTAN 66.
The best quote I ever read about the history of computing languages:
"Djikstra was a snob"
|Thread: Anyone know what is going on at Homeworkshop?|
Hope Adam is OK now. Perhaps best to lock this thread and give him some privacy.
|Thread: Mystery DTI|
3-1 used to be vegetable based, but all things change...
I find a stock of sewing machine oil valuable for 101 uses, its the thinnest grade of mineral oil readily available.
|Thread: ‘Right to Repair’|
Please, no 'great Reset' theories here...
|Thread: Last Night's Astro Image|
This one was actually from the beginning of June:
My first taken using a camera lens with my astro camera, to get a wider field. It was a Zeiss Sonnar 135 f/3.5.
|Thread: Is buying a custom ground tool my only option??|
A ball-nose endmill in a toolpost mounted spindle might provide a good enough finish?
