Hi everyone! I couldn't get ahead this week either but I can already tell you that I've started recording next weeks episode which is going to be about the first winterization stage of the workshop - the door. 

This week I went  for the second iteration of the train where I tried to tackle all the improvements recommended last week. Let me know what you think!

Thanks!!!

DOUBLE BOGIE ARTICULATED LOCOMOTIVE

In this new iteration I’ve gone for an articulated locomotive design with two independent powered bogies attached to the main chassis. I’ve lowered the CG a lot, increased the flanges and removed one reduction stage, also reduced the wheel diameter. I think that with a sufficiently long straight line we could get to 100 kmh easily. If you have any suggestions on how could I do that test please let me know in the comments!

Hi Ivan, you are missing a differencial gear or 2 oneway bearings. This allows the outer wheel to make more turns and does not force the train off the tracks. But I love you designs, keep up the hard work.

I mean cool, and I don’t want to sound like an old record, but are you ever getting back to the big printer, I used to love those build videos.. :(

Many people seem concerned about that, the thing is that the wheels are conical which is how real trains solve that issue, both wheels are fixed to the same axle. Either way, with this tigh tracks the only way it is going to stay on track is by huge flanges, the conicity that those wheels would require to work in this specific case is absurd. Thanks for the advice!!

Hi Stephen, I love to get your feedback, no worries! The thing is that the big printer is no longer a project that I have in mind. For me printers are tools and I have now too many printers. I have one last big printer project in mind but I'm now debating myself between building a big printer or a CNC router. One thing that I'm going to build for sure is a huge CNC laser cutter. Having one will give me a ten fold increase on my project throughput. I'd like to be able to iterate faster and bigger printers go just against that. When I end up building the CNC laser cutter there will be videos for sure. I'd love to hear what you think. Thanks!!
