Re: [CBQ] Aurora Depot Covered Platforms

["James Koretsky jameskoretsky@comcast.net [CBQ]" <CBQ@yahoogroups.com>]

Scott,

Based on initial quotes, the cost per pilliar will be in the ~ $2.50 range each, but it all depends upon the run quantity, the type of styrene used and what the price of Oil is doing at the given time.

As soon as I have a better idea, I'll let everyone else know.

Good morning James,
 
I will be doing the Aurora station on my layout.  If you do offer them for sale, please keep me in mind.  Not sure how many I'll need - but we want to be as accurate as possible.  Any idea what cost would be??  We're also looking for thoughts on the subway entries from each of the platforms.  Finally, we also want to model the elevated through Aurora - complete with the support columns.  Does anyone have any thoughts on those as well?
 
Thanks,
Scott Stearns

Steve,

I'm going to do these in injection molded styrene, already have the quote, and it's the only viable way to get them easily and repeatable.

Cost per part will be cheaper, less time consuming and much better quality than casting when done in styrene.

It also means that I can offer them for sale, should people be looking for them for the same purpose or for a free lanced station with covered platforms.

Make a mold and cast them in plaster or resin

This is the closest I have come up with Railway Age Gazette 1/28/1916

It helps to read thru every page of the old magazines

Not an expert just a student always looking for the answer

James, why not have shapeways print the mold for you? You may be shocked at the injection molding costs...

Here in Seattle, we have an outfit called Fathom who will print almost anything for you. Most bigger cities have these types of service bureaus now. I have had them print injection molding tool inserts out of digital ABS and successfully shot parts in common plastics with them. Each set of tools only yields about 35 parts before they flash or delaminate.

Hi All,

Over the past several months, I've been working on trying to get
dimensions of the Pillars used for the Covered Platforms at Aurora, IL
Depot. I'm working on having these made as a part, and I've come up with
the following 3D drawing.

My inquires for dimensions on the pillars came up blank last time, so
I've done what I believe is the best guess, based on known dimensions in
various photographs that I used to make design the part.

Let me know what you think, if it looks right, looks too big, too small,
etc... and I'll make adjustments. Plan is to have these done in
Injection Molded Styrene, as so many of them are needed for the 3
platforms / six tracks at Aurora, places such as Shapeways would be cost
prohibitive for production.

James
