In typical Panglossian fashion today, I uploaded the STL file for 622’s plastic parts to Shapeways. I might have hit the big “Print” button, if the bounding box hadn’t precluded the use of their highest resolution machine. It’s a good thing I didn’t because the pause gave me an opportunity to assemble all the parts in OnShape. There I found that the gearbox was going … Continue reading Virtual dry fit for 622
I’m just about ready to upload all the printed parts to Shapeways. To support some of the more delicate parts for printing, and more importantly for shipping, I added some sprues. I actually started out making a sprue for all the parts, but then I re-read the pricing guidelines for Shapeways and concluded that this was unnecessary. Sadly, my computer decided it wasn’t going to … Continue reading All the parts that are fit to print
Tonight as I was drawing the step that the fireman would use to light the headlight (imagine that at night at -30 Celsius!), I thought I must be just about finished with the drawing. So, I dropped all the parts into an OnShape assembly to see what is yet to be drawn. I discovered the cab roof is still missing, and maybe I should do … Continue reading Just about finished drawing #622
Wow, construction sure goes a lot faster when teams of professionals show up and work all day, rather than a lone amateur burning the midnight oil! Today, all the cabinets in the train room were reinstalled. So, this weekend we can excavate Mt Flood and get some tools out. As we say in street hockey: Game On! Continue reading Flood update – Game On!
From the first time I entered an NMRA model contest, back in 1994, I have had a challenge with the Conformity section. How did a freelanced model earn full points while my prototype model did not? It didn’t take long at that first convention to fall in with Richard Hendrickson and the Prototype Modeller crowd. The judging guidelines (you may have to log in to view … Continue reading Conformity and the NMRA
Due to flooding, progress on real modelling has halted, and I’ve had to move into the virtual realm. This is okay, as there is loads of drawing work yet to do on 622. I speculated a couple of months ago that some careful manipulation of OnShape’s new Sheet Metal Model feature might yield a good pattern for etching. Tonight, armed with an excellent resource on design … Continue reading OnShape and etched fold lines
A couple of weeks ago, I was lamenting the fact that no trains have run on Pembroke in almost two years. My friend Mark Dance suggested I get a little diesel and convert it; then I could at least bang around a few cars when I want. It reminded me that this was actually part of my original strategy for Proto:87 some 24 years ago: … Continue reading Time-travelling Box Queen
