Wouldn't it be lovely if when putting engineering into prime time (as many other similar programmes have) it didn't have to be dumbed down. I don't see a clash between accuracy and popularity.

Hi Nick,

just to be pedantic (as usual) but a cog is a single tooth. Cogwheels in flour mills etc used cogs around the rim of the wheel which could be replaced when worn.   So the device in question could correctly be called a cogwheel

Best regards.

Hi Bob,

It seems to be the actual pulley he needs not the belts.

Hi David,

if you have the original pulley you can measure the outer diameter of each which is how they are defined. You should then be able to locate a suitable pulley from a supplier such as here or here there are many on the internet. Vee pulleys come in standard steps and you could always use a 4 groove pulley if you can't get a suitable 3 groove - just get someone to turn off the spare pulley 'groove' if your lathe's not working. It is unlikely to be a specially designed and made one . Motor shafts are also standard.

Best regards

Hitsb,

Wot Jason said!!

Wot no picture...

Hi Johan,

That seems to be the way of this forum when a thread goes dead on it's original message. At least it is a way of keeping a thread alive otherwise it would disappear off the bottom of the active list on the home page.

Besides, I've not seem many people posting, and the odd off thread comment wouldn't stop others posting any Lenoir contribution they wish, but it seems not many have anything to contribute, at least at the moment - I hope they will. But I will stay off your thread, I hope it doesn't die.

Hi Jason,

The application is in the YouTube video he linked to above, I tried to post it but it is too wide for this software.  Unusual, as I have posted videos before with no probs.

Hi Andy,

This reminds me of a friend whose father was redundant from a local engineering company about 10 years ago as they finally closed down the remains of the works. He asked about a Bridgeport Milling machine in the R & D dept as his son (my friend) was interested and was told that he could have it for scrap value which they put at £10.00 (ten pounds) They also told him that they would throw in all the tooling as it was redundant. No guessing at his answer. Am I green? Of course not!!

Hi N,

I've seen them, but at what price in the UK. How long will the batteries last and what replacement cost. Further, the overall pollution of an electric car through it's whole life i.e from manufacture to scrapping, can be similar to that of a similar diesel car apparently in some circumstances, The manufacturers deny this of course!

Although the Tesla has a creditable 300 mile range, when visiting my son over 350 miles away I'd have to sit for a couple of hours in a charging station. Fusion reactors are the way to go - perhaps not! I'll just have to wait untl the hydrogen cell is in production although the rush to electricity may stall that now

Hi Kwil,

It's easy, All they have to do is to get the full size one working and then use a de-bigulator (Simpsons 4F02 - Treehouse of Horror VIII) on it to shrink it to fit into an Automobile. SImple

It also happens if someone posts a picture that is too wide, but only in some circumstances, I think it happens when a picture is linked from some hosting sites.

Hi Johan,

At the moment, I am considering building a Brooks-Stent to replace my newly re furbished HH Rest. It is detailed in MEW 16 and 17 and is made from solid bar with no castings and does not require any special equipmnet to build it.

Hi Bill,

My figures came from here and the author gets his data from the ONS (Office of National Statistics). He does not give a figure for 1979 only for 1970 and 1980. in 1980 the average wage is given as £6900 and I simply interpolated backwards. One of my best friends was a legal secretary as your wife and I know that the salaries paid for the work was thought to be relatively poor (especially considering the work they did).

I don't know about draughtsmen though, I left engineering in the early 1970s and lost touch with my friends in the drawing office at that time. I try to use official figures. I do know that at the time the average wage for teachers was considered to be below the national average and the wage was around £6100 in 1980.

Hi,

your requirements and use of the machine should decide your choice. I have an equivalent of the WM18 from another supplier and have found it to be a very capable and dependable machine, it is solid and has coped with everything I have thrown at it. I have no problem using the 3MT tooling, as long as you don't hang on to the drawbar like a gorilla the tooling doesn't jam (at least mine doesn't) and is a good enough drive system. Also tooling such as my E32 collets and drill chuck can be used in my lathe as well as the milling machine.

Hi all,

I enjoyed the programme and thought that Guy's presentation in episode 2 was a bit better. When watching him in episode 1 I lost count of the time he went on about 'them boys', Once would have been quite enough to get the point over. I also took exception to him calling a locomotive 'a train'. The train is what the locomotive pulls. At least in the blurb for the programme they got it right. Surely he should have done, especially if he is trying to be the next Fred Dibnah. Fred was a bit of a rough diamond (and all the better for that) but by gum he knew his stuff, unlike Guy who seems surprised by it all most of the time.

At least in the second programme he began to recognise the cost to workers of creating wealth for the 'Masters'. The other point was that the wooden bike was a one off anomaly and had very little to do with the actual development of the bicycle, but it made for interesting television but as for him 'making' it - that was stretching a point.

Having said that, thanks for the original recommendation

Terry

High Steve,

Very nice mods but I'm not quite sure what your last picture shows when you say High speed for drills smaller than 6mm. A small pulley driving a large one as in your picture will reduce the speed. Surely it would be faster if the intermediate pulley was used so that you can have a large pulley driving a smaller one on the quill, thereby increasing the speed?

At the moment you appear to have about a 4 to1 reduction from motor drive shaft to drive pulley which would give a speed of about 350 rpm (assuming a 1400 rpm motor), a bit slow for very small drills. For example in Mild Steel recommended drill speeds are approx 750 rpm for a 6mm drill and 3000 rpm for a 1.5mm drill and double that speed in brass.

Hi Kevin,

Just had a quick look at the Stuart site and they use two shades of green a dark one for the stands and a lighter one for the model itself or so it appears.

Looking at their pictures and the BS381 colour chart, and allowing for photographic and monitor colour distortion the lighter one appears to be Reseda green (RAL 6011) and the other appears to be similar (but not exactly) to BS 5252 16 C 39 Green.

Lenoir used one of his engines to run a 3 wheeled carriage in the mid 1800s (a bit slower than walking) and used hydrogen as the fuel. Is nothing new as we are talking of hydrogen as the real fuel of the future for personal transport as well as for fusion energy! and here!

I believe that electric cars are a bit of a dead end until we can produce mini fusion reactors to generate the stuff on board.

Best Regards

Any paint factor will mix up a pot of any colour imaginable. If ypu can get the BS or RAL number they can do it without a sample. Otherwise they will need a sample at least 25mm square.

If you can get a sample to compare with the BS and RAL colour charts are here (allowing for monitor differences). For example Boxford used 'Smoke grey BS 381 692' as their standard grey for their lathes until the 1970s.

Hope that helps,

Regards

Hi Bill,

I wouldn't personally try modifying it. Difficult to get the accuracy of the original which is essential for correct operation. As Norman said, if it was advertised as 2MT it should have been 2MT. I suggest returning it and getting a refund. If you purchased it by mail order or online you are protected by the 'Distance Selling Regulations' and have evey right to a refund for an incorrect item, even on eBay.
