A closer look at cutting
A closer look at cutting feeds and gates in a low-temperature silicone spin-casting mould. This develops on some procedures explained in part 2. It does not cover venting: a future video will look at venting this mould to make it cast better.
The equipment used in this video includes a Swann-Morton No 3 scalpel handle with 10A blade (non-sterile). Lino-cutters with assorted blades are available from a number of manufacturers. All can be found easily on Amazon.
Warning: Scalpel blades and lino-cutting blades are very sharp. Take care when using them. A natural hazard of cutting moulds is that you will, at some point, inevitably cut yourself even following good practice. Blunt blades are more dangerous than sharp ones, because more pressure is needed to make them cut: if they slip, they can then be driven harder and deeper into you! Blades can snap, so wear eye protection.
I am not paid to endorse any of the companies or products mentioned: they are simply the suppliers and products that I regularly use in the UK.
