Re: Steam Depot "Curve" Drive for RSD-4/5

 

¿ªÔÆÌåÓý

Tommy,? My Curve drive for the SW did have the gearbox from NWSL mounted to a F unit's floor so I think we cut away large chunks of it as the shell needed to fit.? I forget, but it might have been off center too?? The main difference was the center two axles required a sprocket that was epoxied in place.? The outside two axles also had sprockets but they also had a gear on each axle similar to typical brass imports aka Overland.?

So the power left the gearbox on both ends out to the far axles via shafts.? Then the sprockets then transferred the power to the center two axles with the Delrin sprockets.? I recall that there were clearance problems with all those moving parts, but I can't recall how or even if I got it to work reliably!? There are a fair amount of working parts within those trucks.?

I do remember thinking very hard to come up with making that Maxon motor accept the connector to the shaft.? The motor shaft was too thick, so we chucked the motor into Troxel's lathe, but used the 12volt powerpack to turn down the shaft.? We brought the lathe's cutter into position and very slowly worked it down to size!? That part of the operation was successful.

There also might have been different versions of those drives for the Alco RS1 or S switchers.

What exactly makes a drive a "Curve" drive? From Jace's photos his looks like the Omnicon drives for the F3 abd Shark shells.

Yes, I can always? count on Jace for creative use of some of I've been selling, but I have other clients too.? A relative once said regarding how men and women can finally find a long-time mate; spoken in homespun German--"sooner or later every kettle will find a matching lid!"? A completed kit is a tremendous success when it comes to this sort of thing.

I was given the Railmaster SW kit to build for a product review. back in 3/16's S Railroading days--review was published at that time.? Seeing it mostly looking pretty good, I decided to then purchase the Curve drive.? That was probably much less satisfactory in the end.? Neither of the suppliers--Railmaster nor Steam depot supplied a motor, so I chose a Maxon (we had a surplus electronics that sold them for 1-3$ each).? The Maxon filled the motor cavity to a near press fit.? We ran it only for a couple of brief sessions, then Don Thompson mentioned that SHS wanted one to compare it to their new line of SW switchers.? So I swapped my still unfinished model for a SW7 sample model in trade.? I was happy with the swap and it was one of several of SHS' engines that service my yards.? I do wonder what has happened to the Railmaster unit as I assume SHS sold it when shuttering their business.?

Engine with a Story........

 

Gents.....

First the picture, then the story.? You are looking at an Omnicon brass import 4-6-0 made by Samhongsa.? The tender has been modified cosmetically with the addition of side boards to increase the space for more coal.? This was not the typical NYC practice for sure.? Also, an SHS plastic modified auxiliary water car (formerly a 2-8-0 tender) is attached which seems to have larger sized lettering compared to the tender.? What is going on here?? Read the story below.

Inline image

Now the story.? In the good old daze, the NYC ran a train north from the Boston area toward Canada.? It was a way freight which dropped off cars and picked up cars from various industries along the way.? As time went on, the region developed with more and more industries needing service.? As a result, the run for this train got longer and longer over time.? Eventually, the engine reached a distance (range) limitation due to insufficient water and coal.? It could no longer go farther away from its point of origin because of a shortage of water and coal.? The NYC saw the potential for future business in the area and considered building new water towers and coaling towers to solve the problem.? But those ideas were VERY expensive.? Some creative soul came up with the idea of enlarging the coal bunker and adding an auxiliary water car.? Which is exactly what the NYC did.? See the photo above for confirmation.? The larger sized lettering is correct for the year in which the water car was added.? The smaller sized lettering is correct for the year in which the tender was painted.? Tender lettering increased from 6" to 8" during this time.? Looks like a mistake, but it is not.? Prototype photos exist for all of this which makes the story provable.

Now for the sales pitch:? This engine, a remarkably smooth runner, can be yours.? It is for sale.? Make your best reasonable offer and see if I smile.? If my teeth become visible, the engine is yours.? The story as well can be yours.? If no smile, it stays near the roundhouse shown in the photo.

Email preferred.? Phone works.? ? Loizeaux? aht? SBC //? Global? daht? net? ?1-650-962-1577

Creative load.......no other like it.

 

Folks.......

In my humble opinion, flat cars are..........just flat.? Boring is another word I would use for most flat cars.? It is the load which is interesting and brings life to a flat model.? Get my drift???

Bring a bit of life to your layout with a unique flat car load.? Like the one in the photos below.

Make your best reasonable offer and make me smile.? If I smile, we both will be happy.? Otherwise, the car remains in California.

Talkin' Towers.......

 

Gents.........

Let's talk towers.? Everyone needs one and maybe two.? How many folks actually have one?

There are small towers, medium towers and large towers.? Take yer pick.

Here are some photos of the only remaining towers I have for sale.? Others have already been sold, but these remain for some inexplicable reason.? Two of them have internal recordings of telegraph sounds.? Press the button and hear the dot-dot-dash-dot noises.? Cool......Kids think it is a typewriter and so you can impress your son (and wife?) with your telegraph knowledge.

Making me smile is easy.? Make your best reasonable offer for a tower.? No need to hold back during this holiday season.? If I like it, I will smile and the tower is yours.? If I frown or scowl, the tower remains with me.??

Email preferred.? Phone works.? ? ?Loizeaux aht SBC //? Global? daht? net? ? ?1-650-962-1577

Let's start the new year off with a new tower...........Ed L.

Re: STL File Sharing

 

The NASG web site already has links to the various items that Thingiverse (and others) offer, via both the "Resources" section of the web site as well as the "Product Gallery" section (where appropriate).

If an STL file is already available via Thinginverse (or others), I wouldn't bother to have those files duplicated on the NASG web site server itself. That would indeed be a duplication of effort and wasteful.

What I was thinking about is if there are enough people who want to share their files, but not want to bother going through a Thinginverse (or other) hosting site. It would just be a "service" I'd be willing to provide to those who want to take advantage of my offer. No obligation.

Re: STL File Sharing

 

It has been brought to my attention by someone that a certain person's recent comments have been aimed at me.? So let the following statement of FACT, from this day forward, be public knowledge :
?
The ONLY time I have ever shared or used ANYONE else's files (or photos) was when I had expressed PERMISSION to do so!? Also... I have never ONCE, EVER profited even so much as a single penny on anyone else's drawings!? WITH PERMISION, I have uploaded a few files from a number of people to my old Shapeways page for my own, personal use, and WAS TOLD I could do so as long as I did not profit off of them.? THAT IS EXACTLY WHAT I DID!? So if anyone wants to accuse me of something contrary to this, let him speak up now, or forever shut his lying mouth!
?
I WILL NOT sit by quietly and be accused of CRAP I have not done!? If you think you can prove I have done so, let's have that conversation like men... not hiding behind a keyboard.

It's clear that people on this list have diverse opinions about whether and how they want to share there creative work. This has been true for decades with respect to text, drawings and photographs. Similar concepts can be used for digital files, including CAD/CAM and 3D printing.

?

A nonprofit in the USA has created a system of "licenses" that allow creators to state clearly, in a uniform way, the conditions under which they share things they've created. The system is described on their web page:

?

?

Options range from "view only - no sharing" to "anyone can re-distribute, copy, modify, whatever". Each creator can choose a category for each item they create. For example, someone might choose to place strict limits on something that required a lot of effort and skill, but few or no limits on something else.

?

If you read the "fine print" on Thingiverse.com or their downloads, you'll see that a Creative Commons license is applied to each.

?

Kudos to Peter V. for starting this thread.

Re: 3D Household Furniture

 

TinkerCad is probably the easiest to use, and it's free. It works well if you can think of adding blocks, cylinders, cones, etc to form your model.
Blender is much more capable, but not easy to learn.
?
Also, if you are going to 3D print, you are going to put the model in a slicer, any of which can resize the model. You don't need to find stl's of S-Scale models.

Every model posted in these repositories has a license attached. When I post the model, I get to choose from several possible licensing options. I get that there is a a boundary crossed when you put a model up there, but the tradeoff is that if I don't, fewer people will benefit from my work. Nothing new here - any author, photographer, artist makes the same choice.

I'm not doing any drawing right now, but sometime if I do, I'd be happy for anyone to use them. It would be nice though, if anyone uses the drawings to produce a model, that they provide you with a few pieces.

Re: 3D Household Furniture

 

Dale,
?
You CAN import STL files into 3D programs, such as SketchUp and TinkerCAD. I've been using SketchUp for many years, though it has a learning curve (not near as steep as AutoCAD, thankfully). I don't know if they have a free version, but you can download a free trial version. A good friend of mine is partial to TinkerCAD, but I've never used it.

Re: 3D Household Furniture

 

Dale,
?
The short answer is, that STL is not designed to be an editable format. Most CAD design for 3D printing (in Autocad, Fusion 360 or other software) has proprietary editable formats. These software packages export to STL for distribution and eventual printing.
?
In the print world, an analogy would be PDF format. You would edit your text and images in MS-Word, Powerpoint or whatever, then export to PDF for distribution and printing.
?
Of course, someone has surely created software to modify STL files or to import them for modification. I haven't yet dug into this aspect of today's technology.

Re: STL File Sharing

 

What I don¡¯t get?is the apparent assumption that people will be somehow required to share.

?If you don¡¯t want to share, keep the?file?on your own hard drive. If someone sees the part and asks, say ¡°sorry¡±. Or work with someplace that will print?and mail the physical parts.?

Of course what you can¡¯t easily do is prevent somebody else making a very similar part - not going into a long rant on ¡°intellectual property¡± and I¡¯m not a specialist,?but it would be pretty much impossible anyway. The?downside of digital ?tech?is that those who know how to use the software?can make something as easily as you can, and if it is a model of a prototype or made to fit a specific existing model there may be only one logical way to design it.

I don't get it. I put files on Thingiverse. STL's are resizable. I usually put "S Scale" in the title or description so S Scalers can find it. If some O Scaler wants to scale it up and use it, fine.
?
As an example, I created a drawing for a fuel tank for the AM GP-35. You can search Thingiverse for "GP-35 Fuel Tank" and it shows up. In case you are not familiar with Thingiverse: When the main image shows up, you can click on a 3D button, and then rotate the view to see the part from any angle. I don't think Peter is going to replicate that. If some O scaler or (God forbid) some HO scaler wants a GP-35 tank drawing, he or she is not going to find it on the NASG website.
?
Realize, too, that lots of models have multiple stl's. My "S Scale passenger car detail parts" has 15 stl files (so far), photos of completed assemblies using them, etc. That would be a big job to replicate.
?
I would think at the most, Peter could create an index to files that were stored in repositories. Then it is totally up to the author to mange the access.

Dear Ben,

being someone with four to six left hands (minimum!), my last attempt to disassemble those 1rst run trucks ended with a bunch of parts and a number of springs smaller then with what I started ?. SMM trucks are also available in a 100 ton version with 36" wheelsets. What makes a visible difference in my eyes. That does of course only function with the smallest possible flanges. Otherwise you'll have to lift the carbody into the "high water" region again - what no one wants and needs...
