|Thread: Water pump dimensions|
Thanks for the help Jason.
Thanks for the replies. I will now go ahead with 1/4" offset on the eccentric. The eccentric dimensions on the drawing are wrong then. Thank god for that. I've fabricated the body, but did not start on the eccentric yet.
Hi, On my 2 in D & NY Traction Engine that i'm building I seem to have a problem with the water pump dimensions. That or I missing something. The water pump plunger is described as 3/8" bore with a stroke of 1/2" . When I look at the eccentric drawing, the offset from the centre of the drive shaft to the centre of the eccentric is shown as 1/2" To me that gives a stroke of 1". If that is right, then the plunger dimensions are wrong because at a 1" stroke the graphite packing on the plunger will come out of the bore. Of course, I could be completely wrong. So can any one help me please.
|Thread: Fire door|
Thanks for the replies. And thanks MichaelR I will use this one. And thanks JasonB, but my fire hole is round not oval.
Hi, Some help please. The traction engine i'm building (D & NY in 2in scale) dose not have any drawings for the fire door. I was wondering if anybody can send me some dimensions etc. I know I could work some thing out myself, but things like the vent holes in the door would be a guess.
|Thread: Live Steam Models|

Hi, Please can any one say if the web site called Live Steam Models are ok to do business with because I have had problems with suppliers before and do not want to be caught out again.

|Thread: Advice please|
Thanks for the replies. I'm kind of hoping he might see this and make contact with me. But I'm not holding my breath.
Thanks for reply's. I already have that book. And very good it is. Recommend it to everybody who is painting their models. Jason, quite surprised that the parts you mentioned are not glossy. Is a full gloss just for show case models.
Hi, I'm thinking ahead for the types of paint and finishes for my 2 in scale traction engine. Can someone tell me if I should use enamel or polyurethane synthetic on the Boiler and hornplates, and should it be full gloss, semi gloss or satin.
|Thread: Cylinder mounting.|
Thanks Jason, that makes it a lot easier to do than a load of blind holes with not much depth.
Thanks Mike. That's what I would like to do my self but wasn't sure if doing it that way would tell the pressure in the boiler to tear along the dotted lines. ( Stud holes) !!
Hi, I'm currently building the D & NY in 2in scale. My question is to do with the mounting of the cylinder casting to the boiler. The boiler has the extra copper plate silver soldered to the outside where the cylinder is mounted. But do the cylinder mounting bolts/studs go into blind holes, or is it ok to drill right through and then use studs. It just seems that there is not enough thickness of the plate to use blind holes. Can someone please advise me.
|Thread: Keyway steel|
Thanks all, I think I will use ordinary steel.
I thought key steel was harder than ordinary steel. Otherwise I can make all my keys from my own stock.
Hi, I'm trying find a supplier of key steel 3/16 rectangular and 5/32 square. Can anyone help please.
|Thread: Gear cutting|
Well, thank you everybody for all the tips. That know gives me a chance to contact these people and find out if they can make the gears for me.
I’m currently building the 2 in Durham & North Yorkshire traction engine. Blackgates Engineering have supplied me with the various gears, but can no longer supply the set of 5 compensating gears as the supplier has retired. Can anyone point me in the direction of a supplier of finished gears.
|Thread: Milling a T slot ??|
