This are covers a number of the smaller projects to create bespoke special castings that you can use with you Linka Model Making
Beams
You may notice the use of Beams on a number of the linka buildings, these are not standard parts, so you will need to improvise as I have done if you want the beams.
Here I have used a plastic I beam (Lintel), then filled it with a very strong Casting Powder, these can be a bit tricky to extract from the plastic beam but do come out in reasonable lengths
This image shows a 6.4mm beam which when extracted makes around 4.5mm casting
Above is the plastic beam 6.4mm H section beam/column. 6.4mm height & width and will provide you a 3mm Deep cast
