Are they sending out orders recieved before they shut down?

Yes, ARC will continue to process and dispatch all orders received before the site is shut down, to the best of our ability.

There may be a small handful of orders we may find difficult to execute for some reason, which we will come to know at time of execution. Those customers will be contacted, provided the reason, and such payment authorisations will be cancelled.

I have monitored the developments in China, carrying out pro-active discussions with our main suppliers since around the 20th of January this year, to date. I have watched, listened and learned from them. I have also consulted them on this subject, debated the various points mentioned above with myself, discussed this with my team, and came to the decision to close on Tuesday 31st March by midday. This will allow us enough time to deal with orders and all the issues involved with the closing procedure.

Ketan at ARC

Thanks for the reply Ketan as you can probably guess I ordered some stuff last week, nothing that I desperately need though.

Stay safe and best wishes to yourself, Ian and everyone at Arc, I've spent a few quid with you over the years and will continue to do so when things are back to normal.

Thread: What to use for New Worktop?
20/03/2020 15:27:41
Posted by Brian H on 20/03/2020 12:53:00:

My worktops came from a reclamation yard. They were used as shuttering for casting bridges etc on local road building projects and appear to be an exterior ply with a coating to prevent the cement from sticking. Mine have the trademark "PERI".

Perhaps we have a member who works in the construction industry who could elaborate.


PERI are a German construction company specialising in Formwork and scaffolding. The photo shows their formwork system on the Mersey Gateway central pier under construction four years ago.

And I would think ithe shuttering would make a very good worktop too!


Thread: The last straw!
11/03/2020 22:40:39

Nope it's not an urban myth, unfortunately it's true! Story here via the link


11/03/2020 15:57:46

These straws are available with a silicone mouth piece if people want to be safety conscious!

Come to think about it I can't remember the last time I actually needed a drinking straw!

10/03/2020 21:05:01

While doing a bit of research as to what grade of stainless these are made of, I come across the report of a woman in England who died after falling onto a similar straw after tripping while carrying her drink! It impaled her eye socket and entered her brain! Less serious they can also chip your teeth. I think I'll stick to paper straws in future!

It's 304 or 316 food grade stainless by the way.


09/03/2020 23:04:25

Some food for thought here thanks, hopefully I'll find a use for them before they get consigned to the useful bits bin!

09/03/2020 16:55:52

My latest impulsive shopping purchase was these stainless steel reusable drinking straws. They are 6mm diameter, not sure of the bore or wall thickness because the ends are rounded over but they are very thin wall and look seamless. Comes with a neat little cleaning brush too!


Not sure why I bought them, they just look handy, so for £3,99 for 10 I thought why not! Wierdly they had packets of four for the same price.

So, apart from drinking, can anyone think of a use for these?


Thread: Powder coating
09/03/2020 14:41:05

It doesn't need an electrostatic generator. It simply has an earth lead from the gun which clips to the part you are coating. Really easy and simple low cost method which works very well.


08/03/2020 18:07:27

Hi John have a look at electrostatic magic made in the UK. I have got the start up set and it works very well, although I have only used it on motorbike foot pegs and small things, the results are great!


Bought it a few years ago at Stafford classic bike show for around £150 ish



Thread: Amadeal Lathe failed - customer service appalling!
07/03/2020 23:44:08

Just had a look at Amadeal's website and noticed they are selling the new Syil X5+ 4 axis CNC milling machine for £11.000+.

One thing sets my alarm bells ringing is that the machine is fitted with Mach3 operating system, which as far as I know is no longer supported or updated by Newfangled Solutions. I would expect a new hobby CNC to come equipped with Mach4.

Makes me wonder what sort of back up and after sales service this company can offer for a machine like this, let alone a Mini lathe?

Before I retired I worked in an indusrtry where face masks were mandatory, I had to do a face fit test regularly when visiting different customers to make sure that my nose and mouth were sealed completely. The test involved wearing a air hood and an amount of foul tasting spray sent into the hood, you were then given a face mask to wear and the hood was put back on and the spray injected in, if you couldnt taste it all was well if you could another mask was tried.

The masks you see people wearing in the streets in the news are totally useless.

Martin P

I used to carry out face fit tests for clients, the substance is called 'Bitrex' and despite using disposable gloves when filling and using the vapourisers it got everywhere, and it does taste awful! On the plus side it did highlight how many times I touched my face, such as wiping my mouth then licking my lips ugh!! Easy to appreciate how germs spread after using that stuff.

The paper or fibre face masks are not entirely useless because they can contain a cough thereby reducing the spread of infection, and you can scratch your nose with a mask on.


Thread: Electric welder at Lidl
13/02/2020 18:28:22
Posted by fizzy on 18/01/2020 21:10:03:

I once had one of this type, they will tack stuff together but they will not produce a structurally sound weld. Thats not to say that in the right hands (I was a full time coded welder back then - I could weld) a strong weld is impossible, but where a complete novice would struggle with a proper mig set up they would surely fail with one of these. On the cheaper models the wire permenantly live which only adds to make things more difficult. The weld will invariably look like bird poo! I could get a half decent weld on thin steel by using max amps but other than that it would just spit bits of metal at the job which might or might not fuse together. I gave mine to my brother inlaw who most certainly confirmed the above!

I can confirm this also! I bought a similar Aldi stick welder and just couldn't get any weld penetration at all. I will try again and if no improvement it will be binned.

I should have spent double the money and bought a decent welder from Machine Mart or somewhere. Buy cheap buy twice!!!


Thread: Molly 0-6-0 motion problem
11/02/2020 21:46:37

Thanks for the link David. And despite looking I think I have probably only seen one of these Molly's at model engineering shows.

Just noticed the dates of the original postings, my photo is a few years old too!


11/02/2020 18:31:34

Glad you sorted out the problem, I'm building a 3 1/2" Molly too! Difficult to find much info on this model.

I got as far as building up the frames, axles and buffers then work stopped as other things took priority.


You say it is part made, It would be great if you could post up your progress, hopefully it will give me inspiration to start again.


Thread: What a sad day for the British motorcycle industry.
02/02/2020 23:56:26

I vaguely remember the prototype being of a very poor quality build, nothing seemed finished, and nothing seemed to fit properly either, and those wheel spindles must have had huge bearings, all a bit weird! And the fairing did not look like carbon fibre at all. So I can only assume a production bike was never made.


02/02/2020 22:45:19

I must have been to the same bike show as you Steve, it was 20 years ago!

I got talking to Alwyn Melling of Melling Consultancy Design (MCD) based in Rochdale UK, and got hold of his press pack including quite a damning High Court Judgement regarding the conduct of the then Norton owners. The CEO Robert Kilpatrick was arrested on charges of fraud. Norton has a chequered history!

Here is a copy of the V8 Norton MCD 'Nemesis' spec with a claimed 235BHP!


Aside from the Nemesis they had the Norton 'Nirvana' a 1538cc V twin and a Norton 750cc 4 cylinder. There was also a F1 V10 in the pipeline. Interesting company, don't know what they are doing now though!


Thread: How to hand grind 55 degree cutter for 32TPI?
02/02/2020 21:42:44

Could you use a 55 degree thread gauge or a thread angle gauge to use as a template? If you have these things!

Thread: milling crankshaft on cnc mill using A axis
02/02/2020 21:33:15

Great to see some 4th axis CNC and using a John Stevenson program too! Turned out nice.

I use Vectric Vcarve which uses the Z axis as the A axis when rotary milling, bit of a cheat really because it is still only three axis milling not 4 axis. So I had to start writing my own programs for true 4 axis milling, nothing as ambitious as this though!

I need to get my 4th axis plugged in, not used it for a while, I also need a tail stock support like yours before attempting something like a crank.

Is it an optical illusion or is the cutter slightly off centre to the journal?


Thread: Milling plate clamps
24/01/2020 19:38:21

The Warco set is the same one I use on my milling machines, I've made lots of different height / length studs depending on what I want to hold.

Nice job on the plate by the way
