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
The erection drawing for this engine clearly shows a mud drum hanging like a uvula from the bottom of the boiler. Extending from this appendage, the drawing also shows a two-foot lever. This puzzled me for quite a while: surely you would have to unbolt the cover to gain access, and a lever wouldn’t be much help once the cover was unbolted. I was getting … Continue reading Mud drum plug
Okay, it may be time to admit I have a keyhole problem. Ever since watching Dan Gelbart’s videos on prototyping, I’ve been thinking about them. This latest design element might be a keyhole too far. What if, instead of screwing down through the smoke stack to hold the front of the boiler in place, I hook it down? The hook will be a T-shaped bolt … Continue reading Boiler keyhole?
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!
I was overwhelmed by the number of people curious about the state of our basement recovery at the Railway Modellers Meet last weekend. Today we made some serious progress, when Matt, the conscientious floor installer put most of the subfloor down. Like every other worker who has come to our rescue, Matt took one look at the layout, and almost ran for the hills. Fortunately, … Continue reading Update on the Flood
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
