− | Method of Keel Removal and Relacement on a Berwick
| |
− | (by Ian Bartlett Pure Joy)
| |
| | | |
− | Chock the boat firmly under the centre line
| |
− |
| |
− | Keel to remain attached supported by blocks underneath to steady the boat.
| |
− |
| |
− | Form an 8 x 4 to match the profile of the hull just inside the keel stub.
| |
− |
| |
− | If the ground is not perfectly smooth place an 8’ x 4’ sheet under the keel for a hand pallet truck to roll on.
| |
− |
| |
− | Jack up the 8 x 4 with 2 strong Jacks (In this case 1 x10 ton and 1 x 20 ton Railway jacks were used) to lift the keel (with hindsight have the keel to be removed vertical and 12 inches off the ground)
| |
− |
| |
− | Fabricate, from metal or strong wood, a frame for the keel to rest in when removed.
| |
− |
| |
− | Place frame in position and chock the keel to prevent it moving in the frame.
| |
− |
| |
− | Locate pallet truck under the frame and adjust to hold the weight.
| |
− |
| |
− | Remove the locking half nuts on the keel bolts.
| |
− |
| |
− | Slacken the nuts holding the keel a little on each. Continue to slacken each nut a little in turn, DO NOT REMOVE THEM AT THIS STAGE.
| |
− |
| |
− | When the nuts are at the top of the keel bolts gently let the pallet truck down by about 2 inches. (Leaving the nuts on is security in case the whole keel suddenly drops)
| |
− |
| |
− | Hardwood wedges will probably be needed to break the seal between the keel and stub.
| |
− |
| |
− | When free remove the nuts and lower the keel, in the frame, on the pallet truck then pull the keel away.
| |
− |
| |
− | Replacing the keel is opposite of the removal method. Ensure it is correctly aligned before jacking up or the holes for the bolts may be damaged.
