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 ...

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...

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...

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. The cylinders and slide bars are se...

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 ass...

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 ...

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...

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 ...

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.

Trevor

Very nice Steve!!

Look forward to the video.

Trevor

Thanks for passing that on - I will give it a try.

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...

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...

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 wit...

I have been playing with hats on figures. Firstly a solid bowler hat created in sketchup: Screenshot 2023-11-12 at 10.18.18.png Now I have created a figure for my gravity slate train in MakeHuman, exported it,imported it into Blender and posed it. Then I imported the STL file for the hat. much scali...

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...

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...

So what have I changed since it was last videoed on the track? Firstly I have "fettled" the steam motor. One piston was a bit stiff in its cylinder, the cranks were hitting one of the bearings on the layshaft, and actually hitting the layshaft at the bottom of their motion. It is running m...

It is a while since I have worked on this, but I have made significant progress over the last week or so. Rather than explain how I have modified it first, I will share the outcome so you can see the result - and then I can explain what has made the difference, and what has yet to be improved. The v...

Phil

You have made remarkable progress since I last looked. It looks brilliant.

Very impressed.
