Hi, I'm Lena

My tools

• Casting weight calculator - A wee shortcut to calculating material weight required for casting based on specific gravity
• Volume weight calculator - A quick way to see weight of different metals when given volume. Mostly for use with CAD
• Metal cost comparison - See how much more or less it costs to produce the same piece in a different metal, based on price and specific gravity.
• Rainbow splitter - A tool to split a rainbow gradient into arbitrary number of distinct colours. I use it when picking gemstones.
