Legs
Last updated: 19 October 2026
Overview
October 2026 correspondence regarding his Fremo modules leg construction.
Summary
| Component | Henk’s Specification |
|---|---|
| Legs | 27mm square |
| Cross Members | 22mm diameter |
| Depth Insert | 9mm into square vertical |
| Fasteners | M6 Wing bolts + wing nuts (or insets) |
Construction Method
- Henk recommends that 6 mm marine plywood is sufficient for module tops and sides when adequately supported to prevent warping. He advises keeping modules as light as possible, noting that he has only used 9 mm plywood for boards 1.25 metres or longer with heavy track loads such as fiddle yards
- 2 cross members for each pair of legs
- Legs screwed with M6 wing bolts and wing nuts (inset M6 alternative available but takes more time)
- Forstner drill needed for recessing round dowel into square vertical leg (9mm depth) — allows the 22mm round bar to protrude 9mm into the 27mm square leg
- Henk recommends using 8mm bolts instead of 6mm spec to allow some play during module connection
- Landscape-dependent choice: Depending on the landscape: flat top or open to allow undulations and appropriate side boards.
