Agree joints to both bogies need to be flexible, but there is no need for the motor to be exactly central.  It doesn't matter if one shaft is shorter than the other.  If the flywheel is too close to the bogie for a flexible joint then suggest doing away with one of the flywheels and replace with a flexible joint shaft so bogie is free to pivot.  With DCC flywheels are less essential anyway due to the pulsing of the motors, and one flywheel will do.

One very minor thing - I do not recall ever seeing a photograph of a B101 with staff exchanger fitted - even back to introduction in 1956. They were elusive beasts, so it is possible - but any I saw from 1971 on did not have it fitted.

 

Thanks Jonathan, that’s me assuming because there was a recess for a Staff Exchanger there must have been some fitted but I checked my small group of Sulzer photographs I did not find any either.

Thanks Noel I'll explore that further.

Did some reading on RM Web.  Removing a flywheel does not appear to be an easy job, see Nile's approach on his thread.

It depends on how the flywheel is fitted to the motor shaft some such as Athearn & Walthers are a push fit on the shaft and are fairly easy release. Heating the shaft with a soldering will break the bond if the flywheel is secured with Loctite.

A flywheel removal tool like this might be useful to have in the toolbox.  http://www.ebay.co.uk/itm/Turnigy-25mm-Flywheel-Removal-Tool-RC-Model-Engine-/301489102310?hash=item4632269de6:g:35MAAOSwZapZxM2m

I've put the Sulzer chassis on the back burner for a while until I decide the best approach.

Meanwhile something less complicated:

CIE Bogie Fertilizer Wagons

 

When MIR closed it's doors I had only 3 Fertilizer Wagons and would like to have a few more to replicate the two great pictures in Jonathan Allen's great book, '35 Years of NIR' showing Hunslets pulling a Fertilizer Train to/from Waterside (pages 101-102).

 

When Ian McNally (MIR) came back on the scene last year I was able to get 4 Fertilizer Wagon Kits.

I decided to use Bachmann Y25 bogies instead of kit ones but used the white metal sides of the MIR's which brought out the bogies to the right width. I used plasticard to connect the bogies to the resin body.

This latest version of this kit has different doors and I attached them as individual ones covering my finger tops in superglue in the process.  More pictures of the build.

Only painting, decals to be added and then final assembly.

Just want to mention that is a Denis Grimshaw shot and NOT one of mine.

Nice wagons, good work. You could consider having some loaded up.

Maybe with a false floor near the top, so you only need a small load to cover the false floor.

 

I intend to fill some Pat. I would fill the body with packing foam and add the top layer of bags but it's a future project.

CIE Sulzer -Decision made on the chassis.

 

You may have read on Post #370 the problems I had with the cutting down of an MM 071 chassis to fit a Silver Fox Resin body Sulzer.  I finally decided on what way to tackle it, by doing what should have been done in the first place, cutting the chassis on both sides of the motor/flywheel and reducing the drive shafts accordingly. 

 

post-12350-0-01713300-1507222184.jpg

 

Taking a hacksaw to a chassis is not for the faint heartened but it had to be done.

 

post-12350-0-45095400-1507222244_thumb.jpg

 

The body was joined using Araldite and left to cure for a day.

 

post-12350-0-83830600-1507222254_thumb.jpg

 

The metal section removed was placed on the other side but more dicast metal sections had to be added to get to the right length.

 

post-12350-0-85948800-1507222268_thumb.jpg

 

I ended up with a chassis that looks like this.

 

post-12350-0-26647100-1507222280_thumb.jpg

 

I used plastic square tubing to fill out the gap on the left hand side but the underneath was a dicast metal section.

 

Next the bit I was not looking forward too, cutting the length of the drive shafts and joining them with evergreen tubing.  Of course the tubing available was not the right internal diameter so had to be drilled out.  

 

post-12350-0-28388500-1507222292.jpg

 

I was not happy with the likely resilience of the evergreen tubing so I searched the Net and came up with PTFE Teflon Tubing with the right internal diameter.

 

post-12350-0-78835300-1507222303_thumb.jpg

 

It provided a tight grip on the drive shafts and initial test showed good results.

 

Below is a video of the completed model in action along with an earlier Sulzer I built a number of years ago.

Well done Kieran.  Fabulous end result, and really helpful information.  B103 looking and running really well.  I have had a donor 071 lined up for an SF Sulzer and an SF A class for the past year but your success has inspired me to have a go this winter with them both.  Super job. B107 also looks well and love the B24 class sound project your using.  Hope you get a chance to post this over on the Irish forum because it is a golden nugget of information for all the Sulzer fans.

 

PS: I used a carborundum cutting disc attached to a mini drill to cut down my 141 chassis blocks for the SF C class models.

Query on the Silver Fox 'B' Class body:-   There doesn't seem to be the slot shaped turbocharger exhaust outlet halfway along the body.   It was not uncommon on the prototype to see flames and sparks coming out of it.

Excellent work as always. One very minor thing - I do not recall ever seeing a photograph of a B101 with staff exchanger fitted - even back to introduction in 1956. They were elusive beasts, so it is possible - but any I saw from 1971 on did not have it fitted.

 

It took a while but I found a picture.

Good Heavens - I'm having to sit down after seeing that!

 

1957 is some 14 years before I joined IRRS, so that Journal is not in the collection. Nevertheless, you learn something new every day.

 

Strong drink may be required to aid recovery.

Fertilizer Wagons Revisited

 

After building 4 kits using Bachmann 25Y bogies I was so impressed by their smooth running I decided to re do my 3 original Wagons with these bogies as well.
