Thread: Diamond burrs
12/04/2019 13:05:03

Hi All,

The (slightly tortuous) title says it all I think - I have a couple of sets of these burrs, some sourced from Dremel and clones, others that I bought many (many!) moons ago.

Apart from the obvious glass, ceramics and other super hard stuff, are they any use for softer materials. In this specific case, I am thinking of a tough but not unmachinable steel where a Dremel based grinding action would be much preferable to a simple lathe tool.

Thoughts welcomed...

Thread: Changing Broadband
12/04/2019 09:15:33

Timely topic...

I am the IT department for my my father who manages to sort most IT related problems on his own without recourse to me. However he has a major problem with his ISP (Talk Talk) which at various times would be better labelled 'Mutter Mutter' or 'Mumble Mumble'. He was migrated from Tiscali, at the time I helped him select them as the most efficient and reliable ISP around...

I now need to find someone similarly reliable and offering decent (not necessarily lightening fast) broadband along with a couple of email addresses and easy setup. Quality is implied in this search, rather than minimising cost, since I will pay for it in time in the end...

No longer living in the UK, I have little idea who might be a good ISP to try - so I throw this open to the forum for your advice please.

Anyone looking for a good free 2d CAD programme should check out Siemens Solid Edge 2d. I used it a lot before I went to 3d Solid Edge.

I suggested it in this thread too along with a link.**LINK**

(its the first post today, not sure how to link down to individual post level)

I use 3D almost exclusively now but still have SolidEdge on the PC - this is free for the 2D version and comes from Siemens and is a) pretty reliable and b) very professional. Was always very impressed with it.

Needs a new enable key every year and its a pure PC based solution (Mac & Linux, don't know).

Outputs in all the standard formats, don't think there are any restrictions at all.

Thanks Martyn for the link to RC-machines. They appear to carry a wide range of stock in grades I can get my head around and hopefully less expensive on shipping to SW France than from UK.
DaveD

I have recently used "acier-detail-decoupe" on several occasions who, despite their name, also stock Al, brass, cast iron, copper bronze and composites - although I have only taken steel sections and silver steel and aluminium from them.

Prices are displayed and the postage has various options - and is weight driven so 2 smaller packs can be cheaper than one large one with a big carrier.

Ships across France I believe, certainly to this corner of the SE (PACA)

Regards and apologies for any accusations of thread highjacking,

Thread: Problems with RCB wiring - solved!
19/02/2019 22:20:32

(Part 2, posting too long...)

Solution

Part 1 – removed neutrals on by one from the bus bar in the consumer box. Equipment still causes a RCB fail but now ONLY the power RCB associated with one of the neutral wires (assumed to be that from the faulty sockets).

Part 2 – linked that neutral wire to the functioning power socket neutral – Bingo, all works perfectly.

Analysis

The previous owner had installed the sockets or had rewired them for some reason and had failed to notice that he had used a neutral associated with the lighting circuit rather than that of the power circuit. The RCB balances current out on the Live with that returning on the Neutral so in the power RCB, since there was never anything returned on the neutral, it tripped the switch. Similarly on the lighting RCB, this suddenly saw a surge of current on the neutral side unbalanced by any outbound Live side and also tripped.

Moral

RCBs that have unknown wiring or that you have just installed and don’t work – ensure that the Live and Neutral are on the same circuit.

And there goes a Saturday afternoon…

This is intended as an aid to others who may have similar problems and are looking for inspiration...I have an electronics background and a reasonable experience in house electrics, but no expert by a long way. To anyone who thought the solution was obvious, I admire your intellectual abilities, to those others, I hope it may help finding an obscure fault.

Background

When we moved to our current house in France some 3 years ago, I had the garage packed to the brim with workshop stuff, piled in with no chance to sort on delivery. Once the moving dust had settled, I started attempting to sort things out in the garage and fairly early on, needed power and light from the sockets placed on both sides of the building. The pair that were situated directly under the garage distribution box worked perfectly. Not so those on the other side of the garage floor that instantly pulled the house RCB’s as soon as something was plugged in and turned on. Due to the requirements of time spent elsewhere it was only last weekend that I had a serious delve into the problems, having managed with a series of extension cables up until this point.

Architecture

The source power for the garage is single phase and comes via a ‘power’ RCB and a ‘lighting’ RCB both placed in the main consumer box in the house. All of our circuits are either lighting or power and are entirely separate.

The garage lighting and power supplies come through a separate consumer box and have separate trips. There is a further lighting complication since the 3 way switching uses a relay in the box to turn the lights on and off, adding to the wiring.

The cabling is single core, Red, Black, Blue (N) and Green (E) inserted into plastic conduit which is concealed behind tongue and groove covering the roof insulation, so completely invisible…

All Earths and all Neutrals are ganged together in the garage consumer box except those on the 2 functioning sockets.

Symptoms

Plug any device into the socket and power up results in RCB trips going off. This is the case for both earthed and two pin equipment.

Tests

  • Removed socket earth – no change
  • Socket L-N = 230V
  • Socket L-E = 228V
  • E-N =2V at socket and all the way back to the main consumer unit
  • Disconnect power trip, socket L-N = 140V

No obvious other shorting faults.

Hi, new to this site but have been reading Model engineer for the past 50 odd yearsI have lived in france for the past 16 years and have found very few people over here interested in model engineering..Just wondered if anybody on the forum lives over here or has knowledge of clubs etc?

Hi Michael,

I have lived over here since 2007, the last 8 years near Aix en Provence. There is a small club (VAP) run by one of the contributers to ME/MEW, Jacques Maurel based around the Aix/Marseille area. **LINK**

Thread: Never Throw Anything Away
04/09/2018 15:57:51
Posted by Mark Rand on 04/09/2018 02:03:40:

I'd like to work out a way to separate the tiny screws from the ally magnetically, when melting or pouring the HDDs. Having been an IT wallah for 20 years before taking the thirty pieces of silver, I've got a large collection of drives, with the aim of turning them into useful casting ingots. Trouble is it takes quite a while to disassemble a disk drive with the appropriate Torx bits. Crowbarring it apart and ripping out the larger unwanted bits would be far more efficient.

Mark, I think you may be unlucky trying to separate magnetically - I am pretty sure that all of the Torx screws that I have removed are both stainless and non-magnetic.

Dismantling them is both therapeutic and builds your collection of teeny tiny screws - reserve the ripping for the disks themselves and the drive motors - and be wary of the head assembly which I strongly suspect to be Mag alloy from their super-lightness.

Most of my drives came from friendly sys-admins happy to offload a load of dead drives.

Posted by Neil Wyatt on 03/09/2018 08:01:23:

The only things I separated out were any documents that needed to go for secure shredding and a non-functional HDD I need to destroy.

Strip the HDD down - this produces a decent set of tiny Torx screws and some lovely aluminium for casting. Currently in the process of recycling about a dozen of them - the disks themselves are mostly glass based (they go bendy in the furnace rather than melting in with the rest of the Al) or more Al in which case I defy anyone to recover the data after 10 minutes at 700°C!

Thread: marking / layout blue
30/08/2018 14:58:16
Posted by Andrew Johnston on 30/08/2018 14:48:29:

Does anyone actually bother using marking out blue these days? I've got a bottle somewhere but can't remember the last time I used it. With a mill and DRO it's simply not needed. For complex large parts I might draw the basic ouline with a rule and marker pen as a sanity check, but that's rare. I mark out on sheet metal that's going to be drilled/filed by hand, but I don't bother with blue beforehand.

Andrew

I asked about the spray on version on another thread - I used to use it (until I smashed the can nozzle) to spray onto items already in the chuck to help see where cuts were being made - for instance, down a hole to determine where and when the tool had hit a certain visible point. Similarly on the mill, a quick spray over a surface to see that a cleaning skim covered the entire area. Have to say I don't really miss it and with the cans running in at around €25 each, no intention of getting another one.

A marker pen is a good substitute but the spray had a higher chance of getting into hidden corners.

As for general marking out, I am with you - a sketch for a sanity check followed by careful use of the DROs.

Thread: What depth concrete base for a workshop extension?
17/07/2018 17:10:35
Posted by Speedy Builder5 on 17/07/2018 14:33:08:

Simon, I hope they don't float away. When they install septic tanks around here, they fill them with water to stop them floating in the ground water. Even swimming pools can float if they are empty - think concrete Thames barges! Good luck and I hope I am wrong.
BobH

Bob, I hope they don't float away either but given the local geology and our annual rainfall of less than 18", I don't expect a problem - and the builder has installed several others elsewhere too that are still firmly underground.

Watch this space though!

17/07/2018 11:48:28

Timely topic....

The builders are hard at work on my garage/workshop extension (4m x 6.5m) with a feature that might be of interest to others:

I am having two large (5000l) concrete septic tanks installed under the floor which will become part of the structure. They are roughly 1.9m high, 1.6m wide and 2.2m long with a manhole access. We intend to cut a proper trap door size hole in them and install a step ladder style access. Ventilation to be installed as well.

I think we can assume that they will be waterproof......smiley

Just large enough for a set of shelving for all of those things that like to be maintained at a near constant temperature - like paints, glues, etc, etc.

Number 1 will be for workshop use, number 2 will be the wine cave.....

 

The guys have just finished digging the hole - they got down to around 30cm above the desired depth and hit bed rock - this morning has seen the slow pneumatic hammering away, layer by layer.

Gravel to be laid under the tanks, then side filled and then the real workshop foundations dug around them. When the floor is laid the tanks will become part of the reinforcement.

Intending to get one of those super-smooth finishes on the concrete and then seal with 'something'!

ABS has a higher melting point and is prone to lifting from the print bed. However it is not biodegradeable. OTOH none of my PLA prints have degraded, yet.

ABS doesn't distort in a dishwasher, PLA definitely does.

I have a small PLA panel stuck onto our pool robot that has been theer for nearly 3 years with no signs of degrading, bio or otherwise and several other items permenantly outdoors that are not showing any signs of change either. Not sure what PLA's degrade period is but it looks to be quite long!

Me too. Ashamed to say I had one for ages before realising how to use it like this. So quick and easy - and accurate.

Type C is less than £4 from Arc.

Murray

Funny, I thought that the use was obvious cheeky - but I own one like Journeyman with the pointed centre and I have never managed to work out how to use the pointed part for centre finding......

 

Is this equally obvious to all bar me?
