Hi There
I will request it.
It is a programming feature so the web designer will have to fit it in as he is able.

Thread: Northumberland locomotive additional dimension
11/08/2009 12:33:17
Hi There
I am interested to know what Model engineer has done wrong?
 
We took a proven design, published the drawings (which I checked carefully to ensure they were correct to originals) only to find out via this forum that the drawing was wrong. I have no control over a designer making an alteration to a finished drawing before supplying it to us.
 
All drawings are being looked at together with the original builders notes and the original builder has agreed to look at our drawings to ensure any modifications have been incorporated correctly.
 
Perhaps the quickest way round this problem might be to hacksaw the frames in half and braze or weld a spacer in?
 
What do other forum members think?
Is this viable?
 
regards David
 
PS. Oh for a spell checker.

Hi Kevin
Drawings will be in the next Model Engineer that I am working on.
That is 4359.
 
I have checked drawings that have been supplied by designer.
Model Engineer has introduced no errors into the drawings. They were checked against original drawings as supplied. No errors were found.
 
It is impossible for me to make everything published in the magazine and I have to rely on the designer to ensure everything is correct. I do pick up errors sometimes and the errors are rectified before publication but in a case lik this it is impossible for me to know there is an error in the drawings.
 
Model Engineer has done nothing wrong.
 
regards David

Hi There
Yes, as soon as the drawings are redone, I will post them on here.
It is really annoying although no Model Engineer staff have caused the error.
 
If we left as is, the trailing wheels would foul the cylinders.
We move the cylinders we have to redraw the valve gear.
Then we have to shorten the boiler by 3/16 inch.
Where would it end?
 
Better to apologise and ask people to make the frames again than to risk introducing more errors.
 
regards David

Hi There
I have finally contacted the designer.
 
The frames are incorrect.
We will have to publish a new set of drawings.
 
The frames will need to be remade 3/16 inch longer.
The designer altered the 3/4 to 9/16inch and forgot to increase the 2 1/4 to 2 and 7/16inch.
 
Rather than alter the engine to suit the 3/16 difference and possibly introduce other errors into the locomotive the decision has been taken to redraw the frames to the correct dimensions.
 
All drawings are being rechecked as we go.
regards David

Hi There
We are sorting it out.

Hi There
Both the 6inch dimension and 9/16 are correct - frames and valve gear will work fine.

Thread: Northumberland locomotive additional dimension

Hi There
Drawing was modified for dimension but not redrawn so that is why it is not to scale.
The pump spacer was only found too close after drilling to original spacing.
That is why the original photos are slightly different to the new drawings.
The frames will work as drawn, the cylinders are ok.
regards David

Hi There
9/16 dimension on frames is correct.
No need to make new frames.
The 9/16inch dimension is correct.
It was originally 3/4 but was changed to 9/16inch as the pump stay was to close to the firebox front.

Hi There
I will update the front page with the magazine on.
I have had a bad ear infection for 10 days making it hard to concentrate on work and I had to finish the special as well.

Thread: Northumberland locomotive additional dimension

Hi There
I am trying to sort this out.
I have not managed to speak to the designer yet.
Perhaps he is on holiday.
One engine and a working chassis has been built.
 
Paul who took the photos and built the prototype has been in contact and has agreed to check future drawings against his correction notes.
 
He has been away on holiday so did not know there was a problem.
regards david

Hi Kevin
We print corections if we are notified of errors.
However, readers don't receive the magazine and imediately look for errors.  It takes time for the erros to filter through. I am still waiting for the designer to phone me back about the 9/16 dimension.
 
I have checked drawings for errors as they are redrawn. I have spotted no errors created by Model Engineer staff yet. I go through the drawings with the original and check every dimension.
 
If the original drawings have errors, I am unlkely to spot them unless I build the locomotive, which I don't have time to do.
 
It is annoying for me that the drawings have errors bot thy are not of my making.
When I speak to the designer, I will ask him t check the remainderof the drawings.
 
Two locomotives have been built from these drawings so errors should have been found.
 
What do I do, print corrections as soon as any are found or pull the whole series and upset many readers?
 
I think we continue to publish.
 
regard David

Hi Bill
First thing to do is put a floor over the floor.
I used MDF but chipboard or plywood would be stronger.
I dropped a grinder on mine before covering the floor and it went through the wood.
It did land cornerwise.
