Large Scale Central

Sizing an HO model to 1:29

This is a somewhat hypothetical at this point but could prove useful. If I have an HO model that I want to copy in 1:29 would I simply scale everything up x3; 87÷29=3. If I am right then HO IS EXACTLY 1/3 the size of 1:29 scale like USA trains is modeled too.

That would be correct, Devon. Glad to see that thinker is working as designed (https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-laughing.gif)

Amazing what happens when they drain my head of useless information so I can replace it with new useless information.

Didn’t mention that to you on Tuesday when I was talking about my Pettibone Speed Swing?

Devon;

I don’t think I have addressed you directly, during the interesting years of your membership here, so I’ll share an observation which has just passed through my head this afternoon, after reading your latest post.

You sure have been through a rough time, healthwise, but amazingly have stood strong, and never seem to loose that strength we all admire.

Today you suggest that in the “Latest draining process”, of your head, which I’m sure is partly to relieve pressure; you disposed of some “Useless Information” at the same time, only to find that it will likely be humorously filled, immediately with just more of the same.

I for one immediately, realized that, without any “Operations”, and almost without thought, go through this transition on a daily, minute-to minute, week-to-week thoughtless routine. It is amazing how much garbage we store in the limited number of grey cells they claim we have.

I often attempt to bore others with some of my nonsense, on these pages, but fail to do it in any way that earns me any favours, even though my only competion is a rather crude attempt in the form of a tired old game cock, better found plucked in some crock pot along with garlic, and a few vegetables, for flavour.

Keep up the great fight, Devon, and keep your sharing going…Thank you…

Good fortunes ahead, my friend.

Wasn’t this 3 times HO what helped Lewis Poke to decide on using 1:29 as his scale…and remember his first catalogue’s, which featured colour pictures of Athern rolling stock representing future production…

This is going back quite a few years, and many may not have ever seen those early catalogues…

Sounds about right to me. HO is small, 1:29 not so much.

Yes Fred, I too recall seeing adds using HO equipment. More USA Trains than Aristo but I recall a few adds of “new product” done this way.

I still have two catalogs by Aristo Craft (one may even say REA) from the early 1990s that do show HO cars for proposed 1:29 models. I’d have to look at them again, but I don’t believe they even bothered to airbrush out the uncoupling rods on the Kadee couplers!

Most of my “Aristo” track was bought prior to the name change. The boxes say REA.

Thanks Fred for the kind words my strength comes from those around me lending me some. Much of that comes from right here. You all have been hugely supportive and strength giving.

There is a bit of an inside joke in my comment. I love to learn and research as most of you know. But its not just trains. I am constantly trying to learn. I am almost never satisfied with the simple answer. This extends to way more than just trains. And my wife has said from the beginning that my file cabnit is full and need to delete some files. But then when I do I just replace them and thats my problem.

On a serious note… its not PARTIALLY to remove pressure its 100% about relieving pressure. Thats my entire problem. In a nut shell. To much spinal fluid and I dont get rid of it as fast as I produce it.

Devon, have you looked to see if there is a market for partially used spinal fluid (https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-wink.gif)People nowadays will buy most anything (https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-laughing.gif)

Given my latest build, I’m thinking an adder to mash for moonshine. Right up there with embalming fluid!

All good ideas. If I could only get them to install an external spigot

HO would make just fine amusement park ride on trains in 1:29 . just to give you one more nutty idea!

As an aside; somebody posted photos of their project, a really, REALLY small working model, something that would represent G-scale in G-scale or there abouts. I figured with help of a calculator that it would be almost exactly F-scale if held by a 7/8th scale figure!

Hi Eric,

I think HO would be a bit big - 1/3rd of std gauge would be 19" gauge? Almost 2’?

I’ve always thought of “T scale” (1:450) ?

https://www.hobbiesplus.com.au/t_gauge_.htm

The Japanese company that made them even did a ride-on amusement park train (I don’t think they are available any longer.)

Yes, you do need a calculator. This model is actually O scale: 1:48th and the T-gauge track is 3mm, making it a model of a 5 1/2" gauge miniature railway.

There’s an EMD GP8 available in this scale:

https://www.tgauge.com/product/415/emd-gp8-us-freight-train-set

A T-scale 3mm gauge railroad on a 1/29th layout would represent a 3.5" miniature railroad. A bit big for G scale, a bit small for ride-on. Z-gauge, on the other hand, at 6.5mm gauge, would represent a 7 1/2" gauge miniature railroad. [You can do your own math for F scale or 7/8ths.]

At one of the Christmas shows in the B&O RR Museum, there was a module on the Mason-Dixon Club layout which had a house with a large Z-scale railroad running in the yard. It looked a bit big for G scale - and I don’t know what scale the house was.

Jerry in MD has a bunch of HOn30 track from Peco that I found. This is 9mm gauge and will handle his N scale collection, including the WM locos, although Peco calls it ‘crazy track’ as it had NG sleepers/ties. In F scale that is a 7 1/4" gauge miniature railroad! And just to add to the fun, there are a bunch of model locos in the UK available in HO scale to fit the track:

This is “Skarloey” in the Thomas & Friends Narrow Gauge collection. It’s actually a decent model of “Tallyllyn”, the firstloco on the Tallyllyn Railway, which was the first preserved RR in the world. So in F-scale, what does it represent. . . Oooh my brain hurts.

I’ll have a t scale layout someday. Always thought it would be fun to put a t scale layout on a 1:29 flat car as a load.
