Some of the comments in Friday’s post lead the way to thinking about model railways as art, and it’s worth getting a book out of the library to refresh ourselves on the elements of composition. My favourite art book is Jeanne Dobie’s Making Color Sing. It changed my dabbling with watercolour dramatically. One of the things I’ve learned is if you want to make a … Continue reading Challenging composition
Lance Mindheim’s piece last week about prototype modelling strikes a chord for me. You should read it yourself, but to précis, it is an argument for flexibility in prototype modelling to augment appearance. Embedded in the essay, Lance says, Its taken me decades to realize this but the two, appearance and accuracy are, in fact, often mutually exclusive. This realization echoes a theory I’ve been … Continue reading Of Accuracy and Realism
For many years, I was the only Canada Atlantic Railway modeller I had ever met. Then for a short while, Ron Newby was hoeing this very long row with me. Then, he found other, more accessible subjects, and then as far as I know, I was the only one again. A couple of weeks ago, Richard RJ Guitar reached out to me through the comments on … Continue reading And now we are two!
The wheel plan for 622 requires perfect castings. Unfortunately, every attempt so far using my test molds has resulted in large bubbles. These bubbles are not there when I pour the resin, but seem to be forming during the curing process. According to the Smooth-on website, this could be due to humidity, and I should choose a faster-curing resin. I went with their 310, which … Continue reading Bubbly bolster
I should have known I was in trouble when the Tamiya cement so reluctantly entered the syringe. But, my trusty MEK Pak has finally breathed out the last of whatever makes it work, and so, I was stuck (so to speak). So I went ahead and made that test mould with Tamiya Cement. Plainly this stuff does not work the way I think it should. … Continue reading Solvent fail
I was just about to glue my 3D printed wheels to the bottom of a box and rashly pour rubber over them, when my inner project manager whispered in my ear and pointed at the risk register. Wrecking the Shapeways wheels would put me back a couple of weeks and $16 in shipping alone! For once I listened, and so I cast about for something … Continue reading Test masters
My first plastic vacuum chamber for evacuating rubber Moldavia never held much pressure. For this attempt, I poked around at the local thrift store and ultimately came away with a pot and a tempered glass lid that will enable me to see what is going on inside. Until I got hold of it, there was absolutely nothing wrong with this pot; I’m certain it had … Continue reading Vacuum chamber
