fitting rudder stock bushes

made a jig out of scrap mahogany with 4mm holes
at 124mm centers. clamped jig to edge of bench.
positioned hull with rudder holes above jig and weighed hull down with 12v batteries. then slipped stocks down through hull holes into jig thus ensuring stocks in position and vertical. then simply fitted bushes over stocks and rapid araldited to hull. most important to get this right as it locates correct position of running gear.
