AT-CR is DSPIAE's stepped coil roller: a red aluminium alloy rod that steps down through 12 diameters, each 1 mm apart and engraved with its size. Wind wire round the step you need for an even coil, or press a photo-etched part against it for a clean curve, which is hard to get neatly by hand. The fine end comes off, so it is out of the way when you work on the larger steps.

Notes · Q & A
Sprue cutters or a hobby knife — what do I actually need?+
Cutters remove parts from the sprue cleanly; the knife trims the leftover nub and mould lines. You'll want both — they do different jobs.
What's the difference between single-blade and double-blade cutters?+
Single-blade cutters shear against a flat anvil for an ultra-clean cut with less stress on the plastic; double-blade cutters are tougher for general work.
How do I keep tools in good condition?+
Cut plastic only (never metal sprues or wire) with precision cutters, replace knife blades often, and keep files clear with a brass brush.
