Re: Blackstone K-27 Re-motor Kits

Mark Kasprowicz
 

I too think there is a limit to the number of times you can attach a K-27 motor to 12 volts. (I use the BS drawbars in my brass K-series DCC conversion and have a spare socket with just the two outers connected and wired to a DC supply.)

The last time we had a replacement shortage I suggested that it was possible to replace the BS motor with a Mashima 1020. I admitted there were a number of diffIculties - the sabu on which the motor sits had to be adapted by grinding it to take the Mashima front bearing and lowering the back to clear the motors' lower connection points. I also admitted that the shaft was too short to take the worm, flywheel AND the chuff actuator. So some fettling was needed.
I got put in my place by a fellow member here by saying how unsuitable the motor was for the task. Unfortunately he didn't offer an alternative and so possibly condemned a few K-27 to shelf queen status. I withdrew.

My Mashima powered 27 ran for a while until BS had a new supply of motors and sabu's. Was there a whole load of improvement over my 'botch job' and the new motor? Not sure as I don't run trains long enough to make an appaisal.

So here we are again except there have been some changes. Mashima motors are rarer than rocking horse shit. But some K27 owners are upgrading their 27's to TSU2 - I've done two so far - and so the chuff actuator is redundant and the flywheel can be programmed into the decoder. QED, longer shaft no longer needed.
Will there be another run of the replacement motor, the locomotive is 14 years old? Enshalla!
Is there any mileage in adapting the sabu to another motor? Not sure, the boiler clearance is an issue. The very popular Minibea 15 is a possibility, but I haven't tried it.
One thing I'm pretty certain of. With the present trading situation there is no harm in seriously considering alternatives.

Re: Using 3.7v motors (was Re: Blackstone K-27 Re-motor Kits)

Mark Kasprowicz
 

Understand that the electronic components used in decoders are sourced from the cell phone industry and so operate at 3.7 volts. But the motors commonly used at present are a spin off from the automotive industry - hence the 12v standard. Also motor size matters in HOn3, the chances of fitting a decoder, receiver, speaker and a Li-ion battery inside an HOn3 C-16 are remote and we haven't even considered the much bigger n scale market.
I really love the concept but until some serious size shrinking takes place I'm afraid it's not for me.

Re: Using 3.7v motors (was Re: Blackstone K-27 Re-motor Kits)

Good points mick but you overlooked the S-cab operation. It is a 3.7vdc battery powered system. With a 3.7 Vidc decoder the dc to dc converter would be eliminated thus saving space. A battery powered loco does not need keep alive. Motor size does not play a big part in the system. I currently operate brass locos mod for S-cab 3 hours on a fully charged battery-no track power. The v.a in an S-cab system would be the same with or without a 3.7vdc decoder, well, until battery voltage began to decay. The li-ion batts have a relatively flat discharge rate.

Subject: [HOn3] Using 3.7v motors (was Re: Blackstone K-27 Re-motor Kits)

The issue with using 3.7v motors is current draw. Power = V*A, so if you
reduce V, you have to increase A to get the same P, by a factor of a
little over 3 (12 divided by 3.7). Or put it another way, these 3.7v
motors aren't powerful enough to run model locos. And if they were,
they'd be the same size as the current 12v motors, so you'd have no real
saving of space.

I'd also be interested to see how such a decoder could reduce the track
voltage from 14v or so to 3.7v, and still pass 2A or so or so the 3.7v
motor without generating a lot of excess heat.

Re: Help in the Portland, OR area?

Bruce
 

Bill M,

I have experienced the same issue on nearly every layout I have built.  With the current Covid problem I haven't been able to have my crew (I am the youngest at 69 and most healthy) over since February and it has definitely reduced my output!

And putting together a crew to help on a regular schedule is, IMHO, the absolute best way.  In addition to motivation, they can become life long friends.

These forums are one possible source.  Additionally, explain to your hobby shop owner, if you are fortunate enough to still have a hobby shop in your area, your need.  Also, he may let you post a flier in his shop.

Go to a few NMRA meetings, even as a guest.  The Division I am in allows anyone to stand up during the business meeting and say whatever they want.  Ours also allows information like this to be inserted in our newsletter.  Find out who their Editor is and ask him/her.

Good luck.

With cinders in your eyes,

In that case, I retired 5 years ago, then worked on a house for a year and a half.  The railroad you see in the pictures I built in two years in my three car (w stalls) of the garage.  The third stall is my shop area.  It is HO on the lower line and HOn3 on the upper line.  Mule Pass & Woodland Railway lower line.  Woodland Davis Lumber and mining Railroad on top.

Re: Blackstone K-27 Re-motor Kits

Burning the oil off worked for the first 6-8 times for mine, then it just quit running at top speed at all.  I took it apart and watch the smoke slowly roll out as the motor turned slow.  That's when I ordered a new motor from BS.  That was 2 years ago.
