Damien and the crew of the fishing trawler Brupeg rebuild the vessel’s engine mounts using Chockfast, a high-strength, cement-based epoxy. After a failed initial pour, the team removes the hardened material using a hammer and cold chisel, noting that standard power tool blades melt upon contact with the substance.1:34 To ensure a precise engine alignment, they use a dial gauge and feeler gauges to achieve a tolerance of 10 microns.11:14 The team constructs custom molds for the new mounts using core flute and seals them with silicone, applying the sealant into tight gaps with a welding filler rod.10:10 Because Chockfast has a lower surface tension than water, they perform a food-coloring water test to verify the integrity of the molds before pouring.33:19 To avoid drilling through the cured epoxy later, they insert silicone-coated bolts into the molds to create clean mounting holes.25:47 The process concludes with a final alignment check and the use of a flapper disc to smooth the cured mounts.39:42
