I thought about it a bit and decided trying to stuff a 9v motor in the locomotive was a fools errand.  However, adding one to the tender looked pretty straight forward.  I decided to poke around a bit and there is thread on LUGNET and a number of blog posts that describe various solutions to the problem.  The LUGNET thread in particular is pretty involved and uses a gutted 9v motor along with Power Functions.  A bit more than I am willing to take on right now although I do have several dead 9v motors.  From further searching it appears there are a number of solutions depending on how close you want it the train to look compared to standard instrcutions.  I am not too picky, I just want it work and not look awkward.

There was an NCLUG meeting this past Sunday afternoon and I decided to take a loop of 9v track and the Emerald Night along with some parts with me to see if I could make it run.  The key to my idea was to add a single wheel set and a 9v motor to the tender.  Doing this meant tweaking the chassis design of the tender a bit to account for the pin on the 9v motor.  The modification is pretty simple and makes use of some standard size black plates.   I have documented the changes to the tender chassis and produced instructions using Lpub.  The instructions for the tender are not complete – they just replace steps 1-5 and eliminate steps 16-18 in the official instructions.

So does it work?  Sort of.  I say sort of because the modifications to the tender work fine however the tender struggles to push the locomotive through the curves on the small loop.  I think this is due to the large train wheels on the locomotive which are linked together via Technic axels to bind up.

Unfortunately I didn’t have any parts with me that I could use to swap out the axels for simple pins which I hope will solve the problem.  I hope to try this in the next day or two as I want to run the Emerald Night at LEGOPalooza.

Instructions

9v 10194 Tender 2010-01-25 - downloaded 357 times My take on converting the 10194 to 9v by motorizing the tender.

I finally tracked down the LDraw part I was missing to properly generate the instructions for my CTB-6500 Yellow Monster Truck.  The instructions are now available for download as a PDF file (6.67MB).  Enjoy!

This is my first set of instructions done with LPub4 which greatly simplifies the process of documenting a model.  The cover image was generated with POV-Ray.  I hope to have several more models available in the near future.

Check out the Tilted Twister web site and make sure to watch the video.  If you have ever puzzled over Rubik’s cube, this will really fascinate you.  There are instruction available if you want to build your own.

I have very few complaints – what Kevin has done is simply amazing.  If you have ever been interested in creating your own instructions but have shied away because of the complexity of the process, you should give LPub a look!

CTB-6500 is a Monster Truck I built years ago which I have used for NCLTC layouts.  It is one of my favorite trucks and at one time I had visions of offering it as a kit.  Somewhere in the bowels of my basement I have a stash of the large tires which came from the Model Team 5561 Big Foot 4×4.

This entire set of instructions was created with LPub4 except the cover which was done with L3PAO, L3P, and POV-Ray.

A PDF version of the instructions will be available soon.

When Kevin Clague first released LPub I was hopeful that it would make the instruction process easier and it did but at the same time, it posed a different set of challenges.  I could never quite get it working to the point I was happy with it and instead remained with my manual process of batch scripting LDLite.

Recently one of my co-workers has gotten involved with a FIRST LEGO League (FLL) team and wanted to do some CAD work.  I was able to get him up and running and in the process, decided I ought to get myself tooled up again.

I have a pretty elaborate VMware configuration I use for some things at work which works really well to create an isolated environment.  I created a LEGO CAD VM from my solid XP base and installed all of the relevant LEGO CAD tools including the latest version of LPub.  All I can say is wow.  The default instructions are usable although if you have a lot of callouts, which I tend to have, it will generate a lot of pages.  So now I have some learning to do but the initial results are so favorable, that I don’t mind spending some cycles on it.

My first project will be this Monster Truck which I built a while ago and had started capturing in ML-CAD but never finished.  I finished capturing it this morning and was able to render this image.
