|Thread: Speedy Boiler|
I know what you mean about buying a boiler. I find myself in the same position.
I may be saying the obvious but are you aware that your boiler inspector will need to see your work at several points throughout the build. Best to check with your club inspectors from the start of the project. Also many older drawings are out of date in the size of materials and in some cases even type of material. Again you inspectors will correct and update for you.
Best of luck. Chris.
|Thread: bending 4mm copper tubing|
John Barrett did an improved little bender in issue 4345 which was one of my first projects. It has proved very useful and just an evenungs work for someone like yourself. I should still have the mag if you need a copy.
|Thread: Side Lever Engine|
I am almost finished Mogens Kilde's Side Lever Engine which has been built double size. I am now looking at the paint job. Can anyone help with web sites where there might be pictures of similar engines and which bits were painted and which left bare metal. Also would the cylinder have been wood clad for insulation as was the case with many stationary engines.
|Thread: Northumbrian back issues|
I can tell you that the drawings I have do not include the oil pump and still had the unrevised frames but they were a fairly early set.
|Thread: Boiler fittings - is brass OK?|
I'd have a word with whoever is going to do your boiler test when it is completed. I know the testers in the club I attend prefere bronze for fittings. In fact best advice is to talk to your potential testers anyway as many old drawings show parts which are now unacceptable. Also some parts cannot be seen once the boiler is completes so testers sometimes wish to see boilers at various stages of construction.
|Thread: Glanze insert replacement|
I'm with Gordon on this one. I tap replacements in with the hide mallet just to make sure they are located before use.
|Thread: Bending small bore copper tube|
If it is of any help in me 4345 John Barrett had a design for a super little bender which was my first project. It has been used to make all the pipes for Northumbrian as well as several relacement brake pipes for the car.
Formers are easy to make to suit the size or profile of the material to be bent.
As my first project it took me a week of evenings to make but someone experienced could probably knock it out in a couple of hours.
GLR do a vertical boiler and it can be bought in various stages of completion depending on how much you want to do yourself. Usual disclaimer, my association with the company is as a satisfied customer for the Northumbrian parts. They are on ...
|Thread: Marking out boiler tube.|
Thanks to you all. Jason, it was the fine tuning bit that I just knew would be simple.
Kwil, I see your point but being as this is my first boiler i need as many data points as possible. I'll be following Jasons idea of the 90 degree lines as well. Belt and braces and a length of string if it is available.
Jeff, that is wonderful. It sounds a bit Blue Peter but if it works to within 10 thou I'm up for it.
One thing is for certain, this is the third time since starting Northumbrian that V blocks would have been useful. Where has she hidden my debit card???
I have just started maring out the boiler for Northumbrian. I need two lines the length of the tube exactly diametrically opposite. What is the best way to go about this task? I have this feeing that the answer will be so obvious that I will feel rather foolish but not half as foolish as ending up with the dome and safety valve at a jaunty 5 degrees to the vertical.
|Thread: Boiler bushes.|
I've looked and looked, I've even got someone else to look for me (just in case I was 'man looking') and I cannot find the dimensions for bush E on the ME drawings for the Northumbrian boiler.
Could anyone who has completed the boiler help?
|Thread: Suffolk Steam Dredging Tractor|
Thanks to all of you. Andy, you make a fair comment and it is great to hear your views. Ohh but we all had such an open view on the modeling hobby. Chris Stephens naughty little comment says it all.
Jason you are of course quite right in your reminder that my ultimate aim would be a traction engine but my greatest fear is running out of money for castings and materials plus the fact that even experienced builders like yourself advocate the purchase of a boiler at a couple of grand. Unfortunately my wage does not go quite that far. I seem to waste so much on food and rent !!
I would however like to hear from people just how much builds have cost and what would be considered a 'cheap' traction engine. One that isn't too small would be the only limitation. I have found working on some of the small parts of Northumbrian tedious. Jeweler, I am not !!
But......but......but........it's steam........... HONEST........and it's only little.
I am already looking towards my next project. What is it about model engineers, every one I have met has several projects running at the same time and is researching yet another?
I have become fascinated by the Suffolk dredging tractor. An ugly duckling but somehow just .........fascinating.
Does anyone remember it being built, back in the 80's I believe? Is it a difficult build? Are there castings available?
Or should I just forget it and find a traction engine I can afford to build.
|Thread: Northumbrian or Blowfly?|
I would have to agree Peter. 5 inch is a better size to work with and a more usable end product but on the other hand as a beginners project the smaller scale can be built on a mini lathe. There was talk of someone scaling up Northumbrian to 5" way back at the beginning of the series but no mention of it has been made since.
Blowfly looks like a super little loco and like Sweet Pea over here seems to have a big following so help should be availabe when problems arise. (For us beginners they do arise and it's good to know there is a backup team).
I am looking to my next project being road steam but the prices are pretty prohibitive on my limited budget. All that money wasted on food and rent every month !!
Somewhere in the early stages of the Northumbrian series Terry estimated that the loco should be able to pull an adult and a small child. It's major problem will be adhesion I imagine having only the single driving wheels.
Having said that I am enjoying building Northumbrian as my first major project. Terry's write ups have been very helpful and GLR are good to deal with.
|Thread: Suggestion of need for more photos of boiler underside|
Have sent an E Mail for the pictures.
Some time ago the praise worthy and knowledgable on this site told me to throw away my fire bricks and buy a Kaolin Wool blanket. It cost me about £8 from CuP Alloys and has almost certainly paid for it's self in gas savings. Brilliant when heating sheets of brass for anealing etc, they seem to be up to temp in no time at all. It reflect heat rather than absorbing it which is apparently the nature of fire bricks.
Keep the information and photos coming Donald. I've just ordered the set of parts for the boiler and hope to make a start soon. As this is my first attempt at a boiler I will need all the help I can get.
|Thread: Well done at the Harrogate show - fantastic result|
Try Dougie's own album Kelvin. He has some good shots there of the guns in his workshop.
Must add my congratulation to Dougie. Fantastic models beautifully made. Dougie informed me that the War Museum were less than heplful during his research but I'll bet they would be happy to display the models.
There must be someone close to Dougie with a three and a half guage loco of suitable period to create a fantastic photo shoot.
As for the rest of the show, brilliant. Came home full of enthusiasm with an empty wallet and a rather heavy 'man bag' . (Circlip will know what I mean). Well done to all concerned.
