Jib sheet blocks?

Google cheek block and a few should come up or your local sailmaker should be able to order some in.

Hiya Stray,
If you know of anyone with a 3d printer, you could try and make a sample widget for playing with size/shape. Print it, then modify the design with any changes, print...test...rinse repeat.
I find its an easy way to fine tune any weird one off thingammys. As an added bonus, the 3d software will keep all the sizes and angles so you have a thing to take angles and measurements from even if you end up making one out of wood or steel as the finished product..(and its all freeware).
This is a quick go at a 3d model of it, this took about 30 min (sorry its a bit rough on the scale and measurement), so it's not hard to make a basic model. And I'm a numpty at this stuff, so you don't need much skill.

I thought 3 d printers where for guns, boat hulls and hearts replacement parts? Is it the new cnc cutter? No timber please I could shape that in timber myself.

Hard enough trying to get the local S/S company's to do the work require never mind another machine job for them!

And there you have the Australian manufacturing industry in a nutshell.

Here in Japan , with a deep bow, you will get."I apologize from the bottom of my heart , but I cannot complete that before 3 am."

3D printing would be easy, the issue will be the filament thats used.

I reckon the base is going to be loaded, at least indirectly, not just acting as a spacer/angle mount,so probably wouldnt want to trust loads from your heady going through a block that size. That stainless base looks pretty secured.

If you were certain theres no loading, especially in tension, then you could give it a go and keep an eye on it
You can get filaments that have a degree of carbon in it, but like anyhting, there are various properties youd want to manage. eg. effect of uv, and creep

if you do want to play, go to tinkercad.com.au.It basic and easy to get the hang of.
Youd be able to draw the shape in 1/2 hour of sothen most local libraries have 3d printers now.

If you want to post a mudmap SA, I'll give it a go drawing one up for you.
I have printed off a few things for the boat, like a boom end socket to keep birds from nesting in the end, not structural though.
