J17 - Attempting a 3D printed boiler

I'd spent a fair amount of time trying to solder up a belpaire firebox and despite many attempts I really wasn't that happy with the results. So, as much as an intellectual exercise as with any practical expectation of success, I thought I'd try and model the firebox, boiler and smokebox up in CAD and try to print it. This is very much a 'work in progress' but the results are rather encouraging. The layer lines at a .03mm layer height are virtually invisible to my eye and will disappear even fur

J17 - Cutting problems down to size

As I mentioned in my previous blog posting, the splashers on the J17 kit were designed to accommodate the most steam-rollerish of flanges, being almost 4mm in diameter larger than scale. Well I've managed to take them back off the foot-plate. file them down to size and refit them. They look to be about .5mm too large now but I'm ok with a little extra clearance for the springing.     Missing from the kit, but visible on the plans and photographs were the beading around the b

J17 - It's deja vu all over again

So there I was feeling quite chuffed that I'd managed to get the wheels on the J17 chassis. There is a video which includes it running on youtube.   Then I started work on the footplate, I got the buffer beam and valancing on quite nicely and then turned to the splashers. I felt quite good about the job I'd done until I put the footplate onto the chassis and realised that the kit had exactly the same issues as the previously built J20.     Now I don't exa

J17 - Progress of a PDK kit

For those who don't know what a J17 is, here is a picture.   They were a James Holden designed locomotive built for the GER between 1900 and 1903, a sort of half-way house between the lighter J15 and heavier J20.   As I hinted the J17 kit from PDK is also quite 'old school' by today's standards. The frames just had simple holes for the bearings, not even a half etched line as a nod that some people might spring or compensate their locomotives.   Progress today
