Filing down the axle’s diameter
reshaping the cylinders is taking some time, pictures will follow. In the meantime, I could actually spent some time at the workshop.
I don’t own a lathe, so I took on the trailing wheel with a file and a plan: since this particular wheelset can’t be disassembled, I’m trying to build a vice-like bearing. I aimed for reducing the axis’ diameter from 5 mm down to 3.5 mm with a 1/10th mm tolerance (that’s 1/256th inch). …
today I looked on the last picture I posted and compared it to the prototype’s photography. I have to say I’m positively unhappy with the cylinders’ current dimensions. From my point of view they should be scaled down by at least 10%. This would still meet the required cylinder stroke and give the machine an overall better proportion.
Furthermore, I took a closer look at the trunnion (what little could be seen on the photo) and it seems to me that the trunnion’s diameter matches the cylinder’s diameter. So I will give it another shot and redesign the cylinders.
Pictures will follow as soon as I’ve got anything to show.
Dewey Bros. Status Quo
just a very quick update before I’m going to sleep.
I fixed the misalignment on the cylinders, thanks again Frederic from railroad-line forums for mentioning it!
Tonight I just messed around a bit and patched together some very quick’n’dirty drivers. This screenshot serves no purpose whatsoever except providing a bit of eye-candy. Enjoy!
Saddle’s lower half and cylinders
the last couple of days I focused on the lower saddle half and the cylinders. As you can see in today’s screenshots, I rearranged the parts of the saddle halfs. The lower half of the saddle is going to form a group with the trunnion and the cylinder supports. The upper half acts as a counterpart so that the both halves act like a vice to fasten the main frame bars. …
I’m still around, though things have changed. Quit my job and found me a new one that actually leaves me some spare time. Last week I contacted Regner Dampftechnik Company in order to check up on the wheels. It seems I can expect them to arrive in late June or early July. In the meantime I took on Wallace’s advice and reconstructed the saddle. This first image shows what I’ve got so far. …
