Thread: Boyes of York, good value

They also have a set of 5 HSS slitting saws in various thicknesses for about £5 and a pair of diamond coated (both sides) disks for a similar amount.

From memory, the diamond disks are ~ 50mm diameter and the slitting saws start at around 25mm x 0.2mm & progress to something like 50mm x 0.8mm -- if I remember correctly.


Thread: How to model the mechanism of a Taylor Chuck?
04/02/2019 22:57:34

Haven't seen one myself, but is it not just a coarse & very steeply tapered internal thread?


Thread: VAT on eBooks

Now that everyone is a content creator, paying for and taxing the written word could be seen as a strange concept.

Martin (or should it be Eddie ?) anyway, you do make it look easy with MOI, you certainly seem to know your way around that particular package, out of curiosity, what does it cost to buy?

See here for the price, Ian.

I'm Martin, but my 'channel' is named after our dog, Eddie.

I'm no great expert with MoI although I seem to get it to do what I need. The real experts can model cars and engines and everything in between with it

Some examples from the MoI gallery.

Thread: Custom shape Electric radiator

Thanks for the info, and keep it coming. I did wonder if I could roll an existing flat panel oil filled radiator, I may see if I can find one at the junk shop, roll it as an experiment. It may take sometime to find one!

Do you think you could convert a conventional central heating radiator for your purposes? I know that electric heating elements are available for bathroom rads for use in the summer months when the central heating is usually off, but you want a bit of warmth for comfort when bathing.

A few years ago I managed to curve three radiators to fit the bays at home and these were doubles as well.

Once I'd separated the front from the back panel, I was pleasantly surprised how easy it was to curve said panel by leverage and applying weight in the right place. Single panel rads are a doddle in comparison, so you might be able to do what I did, but I have no idea what you'd do about the heating elements.

Part 2.

12/01/2019 14:45:32

Talk on the Alibre Atom thread about modelling a bevel gear prompted me to have a go in MoI.

It's not too hard to do, but it takes a little while to model, so I've split the process into two videos. I'll make the next one later today.

Part 1.

Thread: Elvis at ARC
31/12/2018 14:22:48

Elvis, Angelina, Angelelvis? It's how one see oneself that seems to count nowadays, but I think it looks like James Dean.


Thread: Simple and accurate home "switch"
30/12/2018 20:00:31

I've never installed any limit or homing switches, but if & when I need to, I think I'd consider using a set of vehicle contact breakers or an optical kind of setup.


Thread: Machining small diameter, high l/d ratio parts "one shot"
30/12/2018 01:48:06


You could try one of these inserts that are designed for use with aluminium, they are very sharp and therefore have a lower tendency to bend long, thin parts. Use a 0.2mm radius tool to keep cutting forces low.

I would use 8mm stock with the minimum protruding from the chuck. Take as deep a cut as possible for a distance of say 10mm, for as many times as needed and take a finishing cut of around 0.1mm. Work your way along the bar in the same way until you reach the 25mm measurement. The aim being to use the rigidity of the stock to minimise deflection whilst cutting at the unsupported end.

Got one from Santa this Christmas. Really good fun to play with and the camera is pretty good as well. yes

I think the correct response to that post might be " Don't judge others by yourself!!"

Edited By Sam Longley 1 on 24/12/2018 11:11:36

Could be that: "It's easier to fool people, than to convince them that they have been fooled". A quote often attributed to Mark Twain.

when is a drone not a drone?


...Their release came as Sussex Police said they were relying on eye witnesses and there may have been no "genuine drone activity in the first place".


on that basis it seems that anyone wanting to disrupt critical infrastructure only needs a 'virtual' drone.

We're fooled like this all the time - you've only got to watch "'I'm a Celebrity" to know it

I have the feeling governments everywhere will be dealing more and more with events like this, where cheap, readily available technology is used in an anonymised, decentralised way, to change the status quo.

Althought no drones have been used to my knowledge, the French authorities are finding it difficult to persue the gillet jaune protestors because no person, or group of people have formal control of the movement.

As seen at Gatwick Airport, it'll be a hard thing to fight if things like drones become involved too.


23/12/2018 15:27:13

Is that thing still going on? I thought it had been sorted with the invasion of the country, overthrow of their government and the public execution of Saddam Hussein.


22/12/2018 23:41:12

With all the outrage this event has exposed, I'm sure we're equally appalled when drones are used to deliver actual bombs on people.

To me the big issue is whether or not it will be considered terrorism. This would obviously open the route to longer sentences.

That is usually a bit of a political decision. If the suspect is dark complexioned with a foreign name, it's usually declared terrorism. Lily white homegrown types are usually counted as criminals.

The pair they have in custody at the moment don't appear to fit the terrorist bill. In fact, the bloke's boss says he was at work all day, so you have to wonder if the cops actually have the right couple? Or if they were some lame copycats nabbed after the main act had packed up and gone? Possibly a case of face, egg, impact for the authorities?

Like you say, it will be interesting to see how the exact charges play out in time.

Once bullets start flying, I wouldn't trust anyone to be able to follow their training.

Seems like quite a lot of risk assements either aren't done, are done but poorly, or ignored. How else could Grenfell Tower come about and what about the other ~ 350 UK towers clad win a similar way?

I don't give blind faith to something just because it's been risk assessed - as per my previous comment, how come no seatbelts on buses & trams?
