Removing dumps and spikes ….
When planks are removed the spikes and dumps may come away from the frames with the plank. This generally indicates that the frame is not in very good condition as it did not hold the fastening. If the frames are in good condition the fastenings ( dumps and spikes ) pull through the plank as it is removed. The fastenings then need to be removed using the custom made machine shown in the photo. The bottom photo shows an assortment of fastenings already “pulled” from the ship’s frames.
