The Home Machinist!

to Fender Thanks for the info and link. It would be interesting to see the calculations done to achieve the counterweight offset design. to Sandiapaul. Well I would love to but have little equipment, space, skills or money to do so. However, I have been producing some scale 3D models and drawings fr...

Hello, I've been going through the drawings of the S1B Niagara I purchased from the NYCSHS. I noticed something with the drawings of the main intermediate and back driving wheel centres, which I cannot make sense of. These three drawings show the counter weight offset from opposite of the crank by r...

I am curious as to the purpose of the concave features on the left and right side of the pilot beam on most? cast steel engine beds.

Hello,

There was little on the pipework drawings. When i looked at the elevation and sections there it was, in outline at least. It is the low water alarm. Any information on low water alarms would be interesting.

Thanks

Now that i have sorted out the whistle, can anybody help me with the collection of valves just below and behind the safety valves on the right side.

Thanks

Thankyou, I didn't realise the whistle was there. That must be it. Its attached to the SH steam manifold which also feeds the blower.

I couldn't attach the file. Maybe its too big.

Cheers

hello, I was looking at the Niagara drawings that I purchased from the NYCSHS. And I am very curious about the device that sits to the left of the smoke stack on top of the smokebox. It is shown as a silhouette on the elevation and left hand pipework drawings. I would appreciate the identification a...

That GSC loco bed in Locomotive Cyclopedia issue 1947 on page 8-608 is I'm 99% sure a Niagara bed. I recently finished 3D modelling it and it looks identical. In the image the pilot beam ends have been cut off to bore the cylinders.

Thanks for the information on the ALCO photos.
As an aside, did any of the PT tenders survive? They were used on a range of NYC locomotives and there is references in some of the PT tender drawings of a conversion or reuse as an "oil supply car" dated 7-15-57, whatever that is.

Hello, I only just recently came across these posts. For many years the S1B Niagara has been my favourite locomotive and I am very keen on building one. I have the drawing CDs from the NYCSHS which are brilliant and moderately priced. However, they are not complete, eg. no arrangement of the boiler ...
