Does the gearing really not matter?

With the "Bad" economy, I'm of the opinion that we can look to see most manufacturers cut back BIG TIME, not move to more sensible testing, which would increase their costs.

Aristo has been known to be running close to a point that they can’t afford much debit, let alone a great inventory. B’mann has a bottom line too.

I expect that 2009 will see very little production, and less NEW product than anyone expects.
We might all stand back and watch for emergency sales of whatever product is available, which manufacturers may run in order to just pay their normal costs of staying in business.

It's starting to happen in all manufacturing across the globe, with the first signs being mass layoffs.......read your newspapers.....no not your local rag, in the lower 49.....read more newspapers that cover the news of the WORLD....you will soon see what is actually happening......it is hitting us all.</blockquote>

You are exactly right, Fred.
I said it before. If you really got to have something, you better buy it now. It may not be available 6 months from now.

Buy American. Build your own. Help the World economy, keep your money close and your weapon closer.

Unfortunately, when they shut all the American factories…they sent all the machinery overseas.
I’m still trying to find a pair of US made work boots. An American boot will last me up to two years. I have yet to have a Chinese boot last 6 months.

“An American boot will last me up to two years. I have yet to have a Chinese boot last 6 months.”

I have to have light rubber sole boots, so they don’t leave black marks on the boat decks. Yes, they are made in China, but Tractor Supply has some boots that I’ve worn for two winters and they still are holding up well. Who knows maybe they’ll start out-sourcing to the USA.

33 scale MPH at 13.8 VDC
41 scale MPH at 18 volts DC.
69 scale MPH and at 23 VDC


Holy Crap! Doesn’t that strike ANYONE as excessively FAST???

Maybe I’m the exception, but on EVERY layout that I’ve OPERATED on those would be viewed as slot car speeds. Where are you going in such a hurry?


Bruce, the 69 scale mph must be a mistake. I believe this should have been 49 scale mph - at least this is what comes out from the proportion if the 33 mph and 41 mph are correct. Stan Ames could you verify? Best wishes from Tokyo, Zubi

Just to throw total confusion into the ranks...... What gear ratios are used on Other manufacturers' electric powered, steam profile locomotives ? And.....what motors are being used to accomplish their running successes/failures ? I suppose we could start with Aristocraft, and Accucraft, for starters; taking into consideration their different styles of gearboxes, and overall drives.
Fred:

Good question. A friend forwarded the following information:

Accucraft C-21.
Pittman 9000 series motor.
38:1 gearhead.
1:1 axle box.

He commented that top speed might be a tad slower than the prototype, but no complaints on its performance.

Happy RRing,

Hi Jerry.
As a matter of interest, would you be able to indicate roughly what voltage was going to the motor when the C-21 loco was at top speed?

.. . . Hi All Just to clear up a couple of points on the Mallet.

Ive just watched the video which came with the Mallet (Little River variant) and it says the following:

  1. The Mallet was filmed running on Stan Ames garden layout

  2. Stan Ames is listed as a Technical Advisor to this locomotive

Hope that helps

if the above be the case, why was the reported Technical Adviser referring me to the B-mann about the motor/gearing specs of the 2-6-6-2?

I've had a little time to look through the sites. Chippewa has probably 30 styles of boots. Less then a half dozen styles are listed. The few styles of Carolina boots available were made several years ago. They closed all their US plants 3 or 4 years ago. I had a friend who lost her job............after 18 years. Probably the same situation with the Chippewa boots, new old stock. Ralph

OOK…it’s about time that Dave has received an Articulated Tank Engine. When will the gutting and testing take place. ?

From gears to boots???

Well boots are part of your gear, right?

Sorry for the omission.

He did mention 19V. I think this was his operating maximum, but not absolutely certain.

Hi Zubi.
Now that we have all been dazzled by your undoubted mathematical skills, I was wondering if you would care to share with us your hands on, in the field, experiences of operating the Bachmann K-27?

Also, what experience have you had with the electric powered all metal Narrow Gauge steam outline locos from Accucraft?

How would you compare and rate the performance characteristics of Accucraft locos such as the K-27 or K-28 - v - the Bachmann K-27?

#159

Accucraft did have an overheating problem with their first release K-27, requiring a recall and motor upgrade replacement. no history since motor fix. Perhaps this inspired B’mann to fit a cooling fan. As Accucraft seem to use Pittman motors exclusively, it would seem that they would have researched all the relevant motor specifications before settling on the chosen production gear ratios.

As with the K-27, B’mann do specifically state with the articulated, that their Pitmann motor is ‘specially wound’. Therefore, any references to specs of a Pittman motor, other than that specifically used by B’mann, would be irrelevant. In a previous posting response, Barry commented on the numerous 8000 series Pittman motors that are available. Therefore simply picking a generic series motor spec graph and making scientific findings is not giving the correct results.

Anyone who has dabbled in R/C indoor carpet racing will be aware of the numerous ‘specially wound’ electric motors available, each with their own specifications and yet all based on the same generic motor type.

Hi Tony, I do not have time to play with toys… when I have time for trains, I run live steam. I will wait until you provide objective and verifiable comparison and quality measurements and diagrams so that we can see if and how they are different from those that we have so far!! Best wishes from Tokyo, Zubi
PS metal Accucraft K-27 locomotive does not compare very well with plastic K-27 by Bachmann because 1) plastic one is probably lighter, therefore not capable of converting motor torque into tractive effort 2) plastic one is probably considerably cheaper therefore cannot permit waste of money on sub-obtimal motor choice (i.e. power overkill cannot be a design option) 3) plastic one is probably meant for a somewhat broader market not restricted to proto-nerds running proto-speeds, people who run electric toy trains probably want to have fun too and see their train actually moving;-))…
