I've purchased from these guys in the past and been happy with their products. Not sure how the prices compare with the usual UK suppliers, and of course there's the VAT

From Neil's link it says just that

"...Effectively removes black and brown stains caused by mould fungus and algae" Removes the stains not the source.

We buy the stuff by the gallon down here.

It was worth the wait. Brilliant!!

Yes that would be the reason. One of the "quirks" is not being able to do bulk upload.

Brian

Probably because if you aren't already a member you won't be able to upgrade

You are correct. There must have been a reason why I hadn't used them in the past.

Appologies Neil I'll stop rambling on. But it is a pity that we can't fix the external links to local links and take the opportunity to tidy up the mess while the problem is front of mind

Pete

Neil

I'm sorry but I must say that is a very short sighted view. The website is very much an integral part of the ME/MEW delivery and long term planning is needed. Firstly to be able to fix the lost content and secondly to provide a more complete solution.

People are able to reference ME articles going back 100years, if ME don't provide for all the content of the website to be held locally then you risk gems like Deans V12 build being lost for others. Like other service providers you've got advertisers providing revenue which could be used to fund a hosted content server. You'd be suprised how cheap those services are these days.

I wasn't asking you to do anything other than change a configuration setting on the system to enable editing of one’s own posts.

Then I thought about what you meant by 'its not practical', why some posts can be edited and others can't and when they change from one state to another. I'm guessing it’s about moderation, once a post has been moderated for content it then gets locked so the moderators don't need to go back to it. Otherwise, you'd have to re-moderate all the re-edited posts?

It’s up to you guys really. If you want the forum to be a long-term reference source you need to give people the chance to fix this problem for you.

In order to ensure a reference source, the long-term solution should be that the forums invest in their own storage capacity rather than expect everybody to trump up $399/year to some third party who may or not be in business in 20years time. Maybe you guys need to take the lead and start on the business case, owning your own capacity would be less risk and far more cost effective for everybody.

I've just tried the "right click, open in another tab..." in both Firefox and IE and it doesn't work in either

Pete

The "right click if you are on IE, keep clicking through the ads" approach is only going to work for those few who have been following these threads and isn't that convenient for the casual users. I'm moving all my images to another service provider and have fixed the links to them on two other forums. However, on this forum old posts can't be edited by the post owner. It’s there for new posts and then disappears at some point

I'm happy to make the changes to my posts if the moderators/admins can switch on the edit function for old posts.

Pete

Thanks Nick that is the article I was seeking. That article, the Graham Meek link, Harold Halls page here **LINK** and the Jacques Maurel articles in MEW 245, 246 247 provide enough info to be getting on with

By the way the Michael Cox article was in MEW 251 not 151

Case closed; thanks for your input guys

Pete

Thanks Ian that looks like the article but I'm sure I've seen it in ME or MEW recently. Did Graham have it published in either or am I havng a senior moment?

Rod, It may have been in EIM but I won't have seen it as I don't subscribe.

Why the up to date index for both maazines can be published here beats me. Particulary as Neil is now maintaining the MEW index.

Pete

I'm trying to find a recent article on modifying a chinese "reliance" type drill sharpener. I recall one of the modifications was to increase the angle of the pivot pin.

Any clues please, was it in ME or MEW?

Pete

Re this Jacobs 3 hole business, a lengthy discussion over an uncorroborated statement. It’s not April yet, so is it a wind up?

Pete

Isn't just a case of "reader beware"? This forum is just part of the internet and not everything you may find on the internet will be factually correct. You learn to make your own judgements on correctness and quality and, like life, who's advice you trust and who's you don't.

I did my ME apprenticeship using these forums and appreciated every bit of advice I was given. At the time some of it may have been a bit suspect. I wasn't to know, but it was generally good enough to give me a clue, make a decision, apply a bit of common sense and work out how I may achieve a result with the equipment I had available.

So when it comes to the forum if something does seem right it probably isn’t, just let it go. Somebody may well offer an alternative solution as input to your decision processes.

I must add, when it comes to being in print I would hope to not see errors that are clearly wrong, particularly when there are photos that confirm such. It happens

Had I been able to weld my fan would have had straight blades. Some time ago one of the club members had produced some ‘kits’ for a fan. Except for the method of attaching the blades it looks remarkably like your design, I was given one of the kits and I hadn't seen your article at that point so I grappled with how I was going to deal with fixing the blades and came up with my silver soldered solution, and, after a bit of Googling, the curved blades. I just thought I'd share it.

If anything it’s too efficient, hence the speed controller. Given the opportunity it wouldn’t only pull the fire out but attempt to suck the coal and wood up the chimney.

When you read the instructions you'll see that you will need a diode across the motor to protect the unit from back EMF. Its a 1N5404 so order one at the same time.

I found out too late.

Pete

I wasn't sure that would be the case or whether flat blades should be offset from the radial axis. A bit of googling indicated that any would work to some degree or other. However as I had no way of welding on the flat blades I'd been given with the disks I had to seek an alternative.

I did consider the tabs similar to those used by Brian or tabs a push fit into holes in the discs and the whole lot clamped together as a sandwich with the spacers and bolts.

In the end I went for the copper blades and silver solder. Adding the curved blades wouldn't be a problem. They were just annealled and bent by hand around a 3in tube.

Pete

Here's my nearly finished blower for a 7.25" loco (Dart) with the Jaycar motor (see link above)

The rotor was supposed to be just some flat baldes welded to the two plates. i don't have welding kit so made a hub and copper plades and silver soldered it all together. The other plate is held on stand offs like the main body. Rather than spending time making standoffs I used 1/4" stainless tube and 4ba bolts

By the way the direction of rotation is with the sweep of the blades trailing. I felt that the leading face would swash the air outwards and a vacuum would be created in the concave cavity of the trailing face. The combined effect drawing air from the center

This blower (sucker) is cabable of lifting something the size of a book off the table.

And the speed controller

Hope that helps somebody.

I'd started making a blower along the lines of the article, prior to it being published. I needed a motor and realised I had one of these laying around.

**LINK**

Its more than adequate and needs a speed controller otherwise you'll be sucking coal down the firetubes !!

**LINK**

Seriuosly this motor makes such an effective blower. I was using it for the first time the other day and once I'd got steam up one of the guys wanted to try it. He said "put it on full" as he only had about 10 psi on the guage. He went from 10psi to safety's blowing in less than a minute.

OK Jaycar is Oz/NZ but these are Chinese products so I'm guessing Maplins (are they still around?) will do similar, otherwise its Ebay or Alibaba.

Pete

PS - 7.25" guage locos. The tube for the chimney is 2" I'll do some photos if more details are required.

Once I'd worked out that clicking each of the photos in the album an explanation is provided for each shot it all makes sense. Many ways of skinning a cat and that’s just another way of posting on the forum. Not the usual approach but effective.

Now I'm going to have nightmares about my Chinese lathe. So many similarities to the Warco in the design of mine. That said I believe the 'Chinese way' is to have a common design and many different manufacturers so there's a bit of luck as to which factory your supplier uses. So Gizzly, Chester, Warco, Machinery House, Hare and Forbes et al may use different sources for similar products. I have a Chinese copy of a Deckel tool and cutter grinder. I've seen about 5 different variants with slightly different features and build qualities (mine isn't that good).

(PS - when you find Lathejack get him to pop round and fettle my lathe please...)
