Glad to be of help Dave, and thanks for the tea - hope your boiler turns out as well as I think it should. And get Bob working as well . I assume it didn't take as long this time to get a good joint!!

That brings back memories Joseph. There used to be a trolley bus station at the top of St James' Rd in Dudley. It was a terminus for the Dudley / Wolverhampton trolley bus route. As I attended Dudley Gammar School down the same road I used to pass it evey school day and was fascinated by the web of overhead lines and the efforts of the conductor when changing the dual poles over for the return trip. Unfortunately I never had chance to travel on them as my bus home was a Midland Red.

What was very noticeable was the lovely hum of the motor and lack of diesel fumes unlike the main bus station. When is 'progress' not progress?

Hi Russell.

This is not a problem as the odd DP gears are on special large parts which are intended to mesh together, an example is the geared quadrant and it's associated gear. All normal Meccano gears are 38DP. It's not a matter of concern.

Hi John,

what program do you use for the code to drive the milling machine. Your example is exactly how I intended to do the job but have only got as far as designing my circuits using Eagle files.

Hi John,

Thats the same as mine, bought it for a song from a school that was throwing a couple away. I bought both and gave one away to a mate. As you say they are effective, it hardly notices pcbs.

Hi Michael,

you could always buy a carbide engraving bit or small slot drill and machine through with the milling machine, or even a router with a simple fence - use a sacrificial base of say, scrap mdf and stick the pcb down with double sided tape. I'm about to try milling PCBs on a small CNC milling machine,

Hi,

Meccano gears can be hobbed using a 9/16 whitworth tap. The Meccano worm wheel was originally made from lengths of 9/16 Whit brass studding and the gears made to suit. There is a Meccano gear hobbing machine which will produce them Here is a link. I am halfway through building the model and it is very rigid so far.

Hi Gray, I still have my number 10 set plus numerous other parts

Best Regards,

Hi Douglas,

I use an old fashioned bench shear (ungeared) to cut my boards and it works well, The cutting edge of the top blade is an arc of a large radius circle and the fixed blade is straight along its cutting edge and the angle of attack is about 20 degrees all along the cut. If a straight top blade is used then the angle of attack reduces as the blade cuts. I hope that make sense.

I'll try and make a sketch to explain the principle better and post it later.

Hi Nigel,

Text Enhance is a well known advertising device which causes keywords to be highlighted and links to sponsored advertisers who can subscribe to the so called 'service'. Text Enhance is basically an add on or extension to your web browser and it can easily be removed. See the link in my post above in reply to David Clark

Many developers are trying to get rid of Flash as it is the basis for many annoying ads. If you disable it some content doesn't show. Have a look here.

By the way I allow updates to much of my software and never have a problem. I prefer to update than to have a hacker or hijacker exploit a hole in some application or other on my PC. Many times those who cosily think they are protected can have code running they know nothing about, everything seems fine, until they find that keystroke logging is installed deep in the system. You only find that out when your bank account is cleared or unknown purchases are made in your name.

Hi all,

I would have thought this question would have been better and more quickly solved by visiting a Plumbing forum such as this one as such items are cheap and readily available. Not worth the waste of workshop time to make them I would have thought.

By the way Paul it is spelled Plumb Center. Useful to spell correctly when searching.

Hi Dave,

Hi ian,

Do you have the original publication details for the article as the Popular Mechanics magazines are published on Google Books

Regards

Terry

Hi Rod,

Thanks for that, my library simply calls it Boston, The rest I assumed,

Hi Again Ramon,

There is an American eBay auction here for the very plans you are looking for - at a price, but the seller may be coaxed into answering questions about date etc

Best regards

Terry

Hi Ramon,.

If you can find the relevant details, i.e. year, issue and page numbers the article is probably held in the British Library's journals archive at Boston (Lincs not Massachusetts) and your local library can request a photocopy (a scan these days I expect). There is a small charge for the service, I have managed to get copies of some really obscure articles from 1950s journals. They supposedly have copies of all journals regularly published in the UK.

Hi,

there are several major suppliers for machinery and tools etc. All have an online presence and produce print catalogues, as a starter there are: Arc Eurotrade; Warco; (these two advertise on this page - see ribbon to right of here), and Chester; and of course Axminster themselves sell a lot of metalworking equipment. There are other smaller suppliers who offer similar products as most are made in China.

For materials etc there are many smaller suppliers on line such as Blackgates, Reeves 2000, Macc models, Model Fixings etc etc there are too many to mention in a short message.

Regards

Terry

Another argument for correct spelling? i.e. searches.

Hi Chris,

We used to provide yellow and blue gels for students with dylexia to place over printed matter which simulated coloured backgrounds for the text. It worked well for many with that problem.

Hi Fizzy,

How about a sabre saw (aka jigsaw) with a fine tooth metal cutting blade. Protect the surface of the brass with two lines of masking tape either side of the line. Leave a few thou to file to final shape. I have also used a piercing saw but it needsa a steady hand and patience as well as a jewellers easily made vee block clamped to the bench - see here

Terry
