Suppliers

In no particular order except for the broad categories, a list of places that sell stuff that is relevant to our interests. Personal experience of these, good or bad, would be useful on the discussion page.

London services & workshops

• Blueprint model shop They have a laser cutter, and may also do plastic board.
• Hamar acrylic (ask for Terry). "Hamar tend to turn things around in a couple of days. They can do all sorts of complex plastic fabbing as well as simple cutting. Excellent variety of materials in stock."
• 4D Model Shop "They have a proper shop with racks of sheet material. They also sell the tools and laser cutting services. A quicker way of getting sheet material, but you'll probably have to cut it yourself."
