Lesson 1Intermediate checks during each step: measuring weight, balance, straightness, and visual inspection pointsHere you will set up regular checks at each stage. You will measure weight, balance, straightness, and stiffness, record the values, and use visual checks to spot problems early before they can't be fixed.

You will learn tool choices, drilling order, tapping methods, and fixing small alignment issues safely.

You will create longitudinal and transverse tapers, refine cross-sections, and keep straightness and symmetry with regular checks.

You will check moisture, rough cut the wood, and plan seasoning while using saws, planes, and calipers properly.

You will carve the tip, inlay and smooth the plate, shape head contours, and finish surfaces with knives, chisels, and needle files safely.

Focus is on tool control, reference surfaces, and precise gaps for smooth, quiet operation.

You will prepare surfaces, apply thin even layers, rub between coats, and buff to a good shine while keeping feel, protection, and clear looks.

Focus on tension balance, clean work, and strong fixing with clamps and glue.

You will use safe heating, bending steps, measure camber curves, and stabilise the stick while checking for twist, springback, and leftover stresses.

You will do wire or silk winding, fit thumb leather or grips, shape the handle nicely, and burnish surfaces while protecting earlier work.
