Worklist:
Review 3D print output.
Print latest items.
Wiring survey.

Laurence was busy in the morning, but arrived at lunchtime.

As an initial test, Stephen had produced a set of 3D drawings of stone items taken from a reconstituted stone manufacturers online catalogue (with dims). This included basic flat and angled ashlar blocks, a lintol with keystone, a cill, two corbels and from general photos, 5 gravestones. Geoff had run-off a set in orange and grey PLA material. To keep the items flat on the print bed, a base mesh had been used. The items are cleverly laid down onto the mesh that enables them to be reasonably easily popped off. Geoff has ordered a metal print base sheet to, hopefully, obviate the mesh layer that wastes material and extends the print time.

Stephen's second batch of items, which comprised an urn with separate plinth and a baluster, was now loaded and set to print, then Stephen and Geoff adjourned to the workshop to start the wiring survey. The trestles were set out and the control panel and loom laid out across them. Slowly, each control panel connection 'nail' was traced through to the plug pins and all references recorded. There were a few surprises such as spare wires and plug pins with double wires (loops onto adjoining boards), but all went well.

Back indoors for lunch, the print had finished and the second batch had been started as Laurence arrived. After lunch, the wiring survey was continued and the two main boards and fiddleyard completed. Back indoors again, the print run had finished. All three items had required additional support material to be built up around them due to overhanging elements, that might otherwise deform or collapse. This would have to be removed before the final effect could be seen, so they were divided between Stephen and Geoff to complete.



Some items will need more work to prepare them and others might be easier to laser cut from card. Painting them will bring its own problems, but on the whole, it beats making them from scratch and with a large yard to fill, any shortcuts are welcome.
