Tea-light stands: a Ø38 cup pocket on a column, at the height an engine needs

How do I hold a tea light at the right height under or beside a Stirling engine? · Hardware · basis: Tea light cup Ø38 × 16 from the tea-light-candles entry; heights from the assembled alpha V-twin and Ross yoke alpha engines on this site (cup top 15 mm below the hot barrel)

Notes

  • A Ø30 column on a 50 × 60 × 5 base carries a Ø44 head with a Ø38 × 8 pocket that takes the tea light's cup. The column stands 15 mm from one end of the base, so the base reaches away from the engine and clears its foot.
  • H97: the alpha V-twin syringe engine, cup centred under the hot (+45°) barrel 5 mm in from its tip end, cup top 15 mm below the barrel. h185: the Ross yoke alpha, cup beside the hot barrel (axes 36 mm apart), cup top 15 mm below the barrel's tip end.
  • The pocket is drawn at the cup's diameter exactly (see Mating features).

Questions

How high should a tea light sit under a Stirling engine?

With the cup top 15–20 mm below the hot surface. The h97 stand does that under the alpha V-twin's hot barrel, the h185 beside the Ross yoke alpha's.

What size pocket holds a tea light?

Ø38 × 8, the cup's own diameter (cups run Ø37.5–39 across makers).
