Thread: What Did You Do Today 2021
02/04/2021 21:29:22
the incriminating evidence has obviously been squirreled away
Thread: Building a small bench
02/04/2021 13:50:35
I'm surprised that the Cowell lathe excites resonance - I can't see any adjustable feet on the bench - is the whole bench rocking ? or is the bench top acting as a drum skin (this might be solved by more cross support)
Thread: Buying advice sought re Milling Machines: e.g. Proxxon: FF230 vs. BFW40/E vs. MF70

Mike Cox described a mod to the SX1 mill that removed the tilting head and locked the head to a vertical guide - the head and guide are held by 4 bolts - if a dowel or two were added to lock the the position then possibly sufficient accuracy could be obtained for most applications leaving tramming for when the highest accuracy is needed - just an idea as splitting this way makes the two sections relatively easy to handle - a tramming device based on 2 DTIs mounted on a bar would make tramming a somewhat faster operation.

Just putting the idea out ? - I havn't tried it but I did have to separate the head + column from the table to move my SX1LP into my cellar workshop accessed by a somewhat awkward staircase -it was a few years ago but given my age I suspect others could handle a similar machine this way.

John - there are many books on general workshop techniques which I think will answer many of your questions - 6mm drills I'd run about 200-250 for steel, faster (400 rpm?) for brass. - no way 1000rpm - you don't melt the metal at high speed merely wreck the drill + the motor driving it.
Milling removes less metal per rev - a 1/4" (6mm) carbide cutter yes at 1000rpm tho for a high speed steel cutter rather slower

If you need to drill 6mm holes (you don't state to what depth or accuracy) then it does imply the lump of steel is somewhat larger - that means you need an X-Y table large enough to handle the clamps needed or if you have the money a vice, As pointed out the rigidity depends very much on the weight.

If you stick to aluminium you may be able to get away with a lighter machine. Or as mentioned re 2mm modelling small holes (say 1.5mm or less) can be drilled but the high speeds and small chucks needed are not suitable for 6mm holes

Obviously I'm not aware of your domestic situation but playing around with steel tends to require saws, a large vice to hold the material to be cut etc - and milling, sawing metal etc tends not be compatible with domestic activity, small bits of steel swarf are easily trodden into flooring A small lathe can do some milling and drilling - many models have been built solely with a lathe as affordable milling machines only came in last 20-30 years - what do you want to make in steel?

Bill - explained above - the parallel canal doesn't cover the full canal - the Ever Given choose the non-paralleled bit to plough into both banks.

can you use a wheeled stand/table to move it away from living space - those you mention sound more like toy machines not really suited to steel - look at ArcEuro's offers - milling tends to spread small bits of metal - not usually carpet friendly

I've seen a report on another site that it has been freed and is moving at 5knots towards the Great Bitter Lakes (presumably this will allow it to be overtaken whilst being checked out)

"Come on chaps, lets have a smile, the world is NOT that bad."
but that doesn't mean we shouldn't make it better and removing intrusive surveillance is one thing I am strongly in favour of.

Brexit will mean we have lost the EU's power to stop such surveillance - the UK though has put us under house arrest for months has it is clear no intention to protect privacy - vide even the census asking for permission for things like google etc.

the latest issue of "The Magpi" has a step by step guide as to how to install a PiHole on a cheap Pi3 or Pi4 processor - it might be worthwhile to try it with say a laptop and see what and how much it blocks - similar instructions are probably online
Thread: Power Transformer buzzing when fed via Solid State Relay-Why?
25/03/2021 18:35:14
is the switching perfectly symmetric - maybe there is a dc offset which offsets the operating point
Thread: Annoying phone calls

revenue - it will cost the telecom companies more to stop than any loss the complaints might cause tho in this case probably no loss other than costs of changing numbers (tho like most companies complaints are totally ignored)
Thread: Any advice on how to cut/file a 45 degree chamfer on a 1mm steel sheet to EXACTLY 45 degrees?
25/03/2021 12:49:32
mitre 45deg joins in skirting boards soon separate - the best approach for internal corners is a butt joint but into a shoulder cut in one of the boards.
I suspect the same approach can be used for dado rails

Android is spyware - Google needs to be broken up and certainly to pay considerable more tax than it does but it has been allowed to grow too big and too invasive and, like the crooked banks in 2008 too big to fail, it will need international agreement, currently in very short supply, to bring it back under control.

more importantly are we starting to see the dreaded 'influencers' at work here in that who knows who is possibly paying for such 'recommendations'
Thread: LG TV ... updated webOS
25/03/2021 08:50:25
possibly use VLC on say a Pi400 and treat your expensive but now toxic web enhanced TV as merely a monitor - after all if it can broadcast to devices on your local net it can download malware to them and just as readily upload your banking details to whosoever it wants - I just don't understand people who would admit such a device onto their network or can even trust it not to do these things without your permission.
Thread: Computer Update
23/03/2021 17:50:31
the Pi400 is amazing - what I want to use it for is my pico scopes but so far Pico have it seems fouled up the linkage of the Picoscope software so its not yet possible - I raised this but obviously as a retiree with just 2 scopes I'm not as important as what seems to be industry standard Win10 (that itself amazes me but I guess they get to turn off the spyware inflicted on consumers) but the combination of the Pi and a cheaper 4 channel scope would make a fantastic student tool during the work at home which will continue I think for several more years

Dell products aimed at the business market generally have a good reputation - I'd be very wary of those aimed at the consumer and sold at places such as PC-World - also Dell tended to have some features that can make it expensive to upgrade (eg non-standard PSUs)
