|Thread: NZ Quake|
I seem to have stirred up a hornets nest by saying my youngest if finding plenty of brickwork in Christchurch while on his working holiday in NZ.
Sure, it makes perfect sense to have outlawed structural brick building through out NZ, as Ian had just said.
However my son is finding plenty of brickwork in Christchurch, mostly repairs and re-pointing of older buildings. As Ian found out, someone has to do the repair work and my lad is doing his share to help.
|Thread: Oh dear - splinters or something worse in CNC|
As I understand the process: The core is magnetised by a powerful electromagnet, then pushed sideways into a steel keeper and then pushed sideways into the stepper motor during the final assembly. The magnetised core is never without a keeper.
Taking stepper motors apart WILL ruin them for sure, the core will loose a lot (but not all) of it's magnetic strength. Not a good idea, unless you know something the manufacturer does not.
|Thread: NZ Quake|
Thanks for the update Ian.
You Kiwis are a mighty resilient bunch. Such community spirit, everyone is doing everything possible to help each other. We could do well to learn from your example.
My youngest is a builder and is in Christchurch for a year. Plenty of brickwork for him to do there!!!!
|Thread: Wabeco D4000 drilling issues|
I would advise you to contact the seller or manufacturer to inform them of the problem before you try any remedial action. Making measurements will help you define the problem for them to address but making physical changes may void any warranty.
Would it be possible to mount a DTI on the main spindle chuck and rotate it round a test bar held in the tailstock. This should indicate the concentricity (or otherwise) close too and at a longer distance from the tailstock?
|Thread: Emco Compact 5 headstock taper problem|
Unfortunately there is something odd with the way EMCO have machined the 2MT on all Emco Compact 5 lathe spindles. The taper is machined correctly for 2MT but the taper is located about 8 mm too far into the spindle; so any 'standard' 2MT drill chuck or 2MT ER25 collet chuck will not fit the lathe spindle. The back of the chuck always hits the spindle face before the taper can engage.
What Emco had in mind when they designed that feature is any ones guess. It has proved to be a source of annoyance for many owners. I discovered this oddity after waiting two weeks for a 2MT ER25 collet chuck to be delivered from China, I had to resort to that ungainly EMCO bolt on ER25 collet chuck.
|Thread: MEX Photos for those that stayed home|
Thank you Michael G
|Thread: Is CNC cheating|
That's me ****ed as well.
Where do you want me to send my Gold Medal and the Bradbury Winter Trophy to?
|Thread: THE 2016 MODEL ENGINEER EXHIBITION|
Thanks Jason, I had only looked for the forms on the website without success.
Who knows where to we can find the MEX 2016 Competition entry forms?
|Thread: Cutting oil|
You can count me in for litre size quantities
Everyone seems to agree that Castrol Hysol XF is the way to go.
I can find it for sale in huge commercial quantities, but where can you buy it in sensible small quantities of a litre or two?
|Thread: Plunge saw for brass?|
Rik That's a powerful little circular saw. Just make sure you fit a blade with with a finer pitch than the 1.5mm plate thickness, otherwise you will end up wearing it
|Thread: About tea....|
For those who have survived a diet of compo rations in the field.
Who can remember the taste of tinned compo sausages? They actually tasted quite good.
Can you also remember the tins of 'babies heads' , a very descriptive name for tinned steak and kidney pudding
Years ago we used to bungee lunch full size gliders off the bank. The bungee was pulled into tension by a huge retired dray horse. The horse had spent all of it's working life pulling a brewers dray around North Yorkshire, so was well used to pulling heavy loads. The horse ambled slowly down the bank with one end of the bungee attached to it's halter. When the tension was high enough the glider was released into the air.
One day, someone noticed that the old horse always shut both eyes when it started pulling on the bungee cord. Well wouldn't you? Even the old horse could imagine the consequences, if the bungee cord suddenly snapped without warning.

|Thread: CES Change of Owner|
If we all vote with our feet, then perhaps the new owners will get the message.
|Thread: Making piston rings.|
Understood, If the full size engine does it that way, then you have to do the same.
How does that ring across the gudgeon pin seal the gasses?
|Thread: Millling clamps|
They look to be a very sensible set of clamps you had to make.
That is an enormous block of 2014, it should take you a long time to reduce that to a pile of small chips
