Well I didn't know so I had to investigate!

It's a single-piece (solid block with bored hole) bearing or support block - often used as a budget bearing, but in this case they are being used to support an axle which is prevented from turning by locking screws located in the block where you might expect to see a greaser.
Note the wheel with bronze bearing rotates on the fixed shaft.

Ah, something else learned today!

I got a 3d printer sometime ago and recently I got it out of the box..

Having a little dabble in 3d software, I've settled with onshape. Its free, its full featured and its easy to use. So ticking all my boxes I've started designing odd bits. Gutting, Finials, fencing , door handles. Already I've a few bits and some of these will be available to buy via my website and some items are listed on Modelu3d as well.

I find tutorials a bit hard to stick with and find I learn best when I'm interested in what I'm trying to do. So in that tradition, I wanted to get to grips with software, and I found a turntable drawing that had some interesting features that would keep me interested.

I chose the wheel first.

I had all the key dimensions and nothing was left for me to guess. So I drew the above drawing flat in my favourite 2d cad package Qcad. I really recommend this to anyone starting out in CAD. Its cheap (free) and fully featured and easy to use.

Once I had my DXF file drawn to full size. I imported this to onshape. Simply using the extrude tools, I made this in about five minutes.

Feeling that it was going in the right direction, I did the whole assembley for this section of the turntable.

So this represents about 30-45 minutes work at my novice level so I'm sure those of you who are expert can knock up this sort of thing much faster.

I've exported to a 3d printable file and I'll print these wheels out this evening.


You'll be surprised how quickly you pick it all up! especially with some 2d drawing skills. I'm slowly learning my way around Solidworks (only because work has let me have use of it). there's so many video tutorials out there on how to do certain things that you have to do in a different way to how you'd craft it by hand... Before you know it you'll be designing a whole locomotive... Or is that Just me? I started with no CAD skills what so ever :O

I think you'll find that the 'dead eye' just acts as a clamp on the spindle or axle, the wheel, if you read the drg., shows it has a bronze bush, it is this that revolves around the spindle which is fixed.
The same principle is used on the older style motorcycle swinging arm frames and con-rod little ends that support the pistons . These use phosphor bronze bushes, the reason for using bronze is the fact that it is essentially self lubricating.

Thats interesting. Looking again at the drawing, I can see how that works. I need to update the my 3d now :rolleyes:

Hi Phil. Are you going to that in 7mm as well? If so what will be the depth with and without the pavement?
Yes, the 7mm versions are available in my shop. I'm just building up stock of these as I've had a a few orders in the last month. They are in two depths, third relief and half relief. For this building, thats;

Hi Phil. Thanks for that. Just to confirm that the two depths shown on the drawing are without pavements. Its a bit difficult to see the very light grey outlines on your drawings.

I've got to make a half decent photo plank for a customer and so I thought I'd try and visualise it in 3d. I would normally have bits of track and cardboard to do this but this time, I thought I'd get down with the kids and do it in 3d software.

So with a photo to inspire the design and some of my buildings simply drawn in 3d...

It will all make sense in a few weeks...

Have a look for yourselves https://cad.onshape.com/documents/4...35dec14612cb0158ea/e/3966b1a316c66bc8e08879f9

A little bit excited, to keep up with demand I've added another laser to the stable. 120watt Trotec 400 with vision. The vision will allow me to accurately cut and engrave around preprinted work. I've some exciting plans in that direction.

Brilliant! Look forward to seeing how you get on with vision. Excited to see what else you get up to the excellent progress and projects you’ve made so far. Raising the bar all the time. Cheers, andy
