Re: Palmerston - Small England Loco as built

In fact I think getting it on my skin has inflamed latent dermatitis. Trevor Are you 100% sure this is the superglue and not the resin? I only ask as resin completely screwed up my hands for 10 months, cracking bleeding etc etc, really really nasty stuff. Apparently it goes through nitrile gloves a...

Re: Palmerston - Small England Loco as built

the build volume of this resin printer is bigger than that of my filament printer. Same here. I have been, just for comparison, printing the parts from Rik's GVT wagon on both printers. On the filament printer I need to cut the wagon side and then reassemble, and it's a visible part. With resin, no...

Re: Palmerston - Small England Loco as built

I have made a couple of attempts at printing the body. My initial attempts to slice the whole body as one part were unsuccessful as the slicing software couldn't handle the data density. So I tried just the tanks and peripheral bits: IMG_3508.jpeg I did set this at an angle with the front up in the ...

Re: Palmerston - Small England Loco as built

I now have the footplate reprinted, cleaned up and connected to the chassis: IMG_3514.jpeg IMG_3515.jpeg I am using one of those geared motors, which seem to be very powerful for their size - and of course have a second standing by in case it isn't powerful enough. The top of the footplate has been ...

Re: Palmerston - Small England Loco as built

Really useful thread. I must post about all the problems I am having with resin printing, and I would not have even attempted your chassis orientation for fear that supports would be insufficient to pull that much surface area off the FEP. So it's really good to know that's possible. I am curious w...

Re: Palmerston - Small England Loco as built

I'm particularly impressed by the finish on the top of the footplate. If I'm seeing things correctly, the top of the footplate is the underside of the print and has the supports? There appears to be very minimal dimpling from the supports and relatively few visible layer lines - or is that simply b...

Re: Palmerston - Small England Loco as built

To give an idea of how I plan for the chassis, footplate and motion to fit together a screen shot: Screenshot 2023-11-27 at 19.12.26.png The chassis fits into a slot in the footplate and is secured at each end with bolts and brass bushes bonded into the footplate.

Re: Palmerston - Small England Loco as built

So it worked. I printed coupling rods, wheels, and connecting rods on the smaller printer which I have. The coupling and connecting rods had holes for bushes - trying to make a more "professional" job of it. I have bored and tapped the wheels to take stainless crankpins. So the chassis assembled: IM...

Re: Palmerston - Small England Loco as built

I have found the large resin printer a challenge - in some ways. Firstly each attempt at a component uses a lot of resin - and there is always something which could be better if I made it again. My first attempt at the chassis had the motor mounts integrated into the chassis but at an angle. I also ...

Re: Palmerston - Small England Loco as built

Looking good Trevor. I do envy you your ability to use the 2D drawings in Sketchup, I've tried to do it myself but without any real success. I guess its some sort of knack which I haven't yet found. :oops: It was just a matter of perseverance. I don't give up easily! Well I gave up twice but went b...

Palmerston - Small England Loco as built

Yet another 3 D printed project. There are drawings of the early Ffestiniog locomotives in th e16mm Association special edition covering the early Ffestiniog railway. As usual I have scanned the drawings and imported them into Sketchup. I have moved them around and orientated them so that they form ...

Re: Making "steam" from an atomizer for making mist

I had wondered if there was a way of adding a plume of steam to a battery loco, when you have added a sound card its the one missing element.

A very interesting idea. I will store it away for future consideration.

Re: Am I aiming too high?

Wow Trevor, that's amazing! I wish I knew how to use Sketchup, then the drawings would be extremely useful to but, but alas, I am a Tinkercad special :( I have found this on the net, I think I might be able to construct something similar in Tinkercad and use it as the hex part would be made to slid...

Re: Am I aiming too high?

Some thoughts on using sketchup if you are unfamiliar with it. In the main menu across the top there is a heading "camera" Use it to change where you see the model from front top back etc. Start off using the 'top' view and draw things in two dimensions. Boxes circles lines and things like that. Get...

Re: Am I aiming too high?

Hi I also use the free software. "Sketchup Make 2017" is the version I use and it it still to be found on the internet. To answer can I seperate the components into separate stl files? Yes. I create the drawings as a single file for the whole model, and create each component separately within that f...

Re: Am I aiming too high?

I have also thought about making a Shay. In fact it was something I thought about making next - to follow on from the three D printed 4420. I was thinking that it would be a appropriate for a 3 D printed live steam model. I have drawn it up in Sketchup - and it is near enough ready to print. It is b...

Re: Kerr Stewart 4420 - Live steam and 3D printing

So I am much more satisfied with the way that is working, however there is room for further improvement. I noticed as I was recording the video that oil and steam was escaping from the lubricator cap - so I will have to look at why, perhaps it wasn't screwed down properly? While the reverser is seal...
