Re: Diffuser for blow down valves

I think I remember seeing a thumbnail drawing on the Norfolk and Western Historical Society page of the drawings they sell. It might give you ideas.

Re: Kunkle safety valves

My recollection is that the compact 1/2" Kunkle that is often used for live steam locomotives is actually sold/ASME rated for use on unfired pressure vessels. Assuming you are looking for a safety valve for a boiler, Kunkle probably wouldn't mention this as an option. I read somewhere that this valv...

Re: Nathan D.V.7 Lubricator

It will be a long time, if ever, before I will be able to do that level of super detailing. I noticed them in the Nathan lubricator booklet and was curious if anyone have ever tried to include them in their modeling.

Re: Nathan D.V.7 Lubricator

Just curious. Have any of the super detailers included simulated terminal checks in their simulated lubrication lines? On the prototypes they are placed at the device being lubricated. They are a combination of a check valve and a pressure relief valve so that the oil doesn't feed until there is at ...

Re: Nathan D.V.7 Lubricator

I have a couple of circa 1940 booklets put out by Nathan, one on the DV series lubricators and one on the DV-4. They include a number of line drawings. you should be able to scale the drawings from the mounting bolt spacing. Send me your email address by PM and I'll send you copies. FYI, Steamtown h...

Re: USATC S-160 Consolidation

The print quality isn't as good as there are some layer lines and a bit less detail, but PLA printed on the FCM printer also works for investment casting. It's a lot cheaper than using castable resin.

Pyle-National Headlight Drawing

Does anyone have a line drawing of this circa-1940 headlight that they would be willing to share? I'd like to have a go at building a model of one. If I take a 100 mile round trip I can measure the prototype, but I'm trying to avoid leaving the house unless it's necessary until things settle down an...

Re: USATC S-160 Consolidation

Some thoughts and things I’ve learned about the capabilities of 3d printers to print precision mechanical parts. The photos are of a couple of generations of test prints (frame brackets for my S-160). The dark grey part was printed on an Elegoo Mars DLP (resin) printer, modified with a dual linear r...

Re: Steam railroading to return to Alaska!

The July status report is posted at http://www.557.alaskarails.org/restore/progress-reports/2020_07/index.html. More tools to add to the collection of what is needed to maintain a steam locomotive. Two pressure gauge dead weight testers, one an Ashcroft, the other an Ashton. Why two? The Ashcroft, o...

Re: A Real Dirty Job

When I need small angle or channel I cut square tubing lengthwise and mill the edges to size. On the smaller stuff the corners are relatively square and it comes in several thicknesses. It's available in mild steel and SS. I usually cut one piece of square into four lengths of angle. It tends to dis...

Re: Aluminum switch points

I don't remember the details, but long ago we had some switches that had a steel insert/wear piece bolted onto the last few inches of the point. Your small rail may have been what was called "Culp rail." One problem with a stub switch is that a lack of attention results in running the train onto the...
