Now that both longitudinal bulkheads are now epoxied in position with epoxy and silica thickening powder.

Both bulkheads are now glued in position with epoxy with silica powder mixed into thicken it into a paste. They are now fixed in position with braces at the bottom edge against the bilge stringers.

There are blocks screwed on to the sides of the cross beams to ensure the bulkheads are helded in the position while the epoxy cures. 

Once the epoxy as cured the braces and blocks will be removed and the bulkheads will get a coat of epoxy and then bilge paint to seal the plywood against any moisture that may find its way into the void places once the new plywood floor is fitted.

As in the way the bulkheads were fitted before the top edges to stiffen the top edge from moving around when screwing the new floor down on to the new rails fitted to the bulkheads.

 

The two longitudinal bulkheads now fitted to the shape of the hull and the tops made to the level of the floor.

Now that the bilges have been painted with their first coat of bilge paint, it was time to fit the two longitudinal bulkheads. First dry fit them along the bottom edge so that they fit the profile of the inside hull and against the longitudinal bearers which the bulkheads sit up against when they are glued in position.

The bulkheads are braced against each other so when the epoxy resin and filler is applied along the bottom edge they will be held in position while the epoxy resin goes off and cures.

In order to keep the bulkhead vertical and in place a number of floor bearers will be fitted along the length of the bulkheads to ensure they stay in the correct position and the fuel tank will fit back in the position it came out of when the old bulkheads came out to be replaced. 

 

Update on Tremlett/ Stately speedboat restoration

Having put in a set of temporary floor beams to give us the height of the top of the new longitudinal bulkheads to be fitted along the two lower longitudinal stringers it was time to bilge paint out the space under the floor which will be fitted once the new longitudinal bulkheads are bonded and glassed in position.

A photo of the inside of the hull before it was painted.

Then the same space painted with its first coat of grey bilge paint.

The aft section of the inside of the bilge space after it was cleaned and made ready to be painted.

The same space painted 

Usually for boats like this type of boat to to have cross over layers of veneers  when the rest of the hull is double diagonal layers of mahogany veneers.above the floor space.

The layers in the bottom are cross over layers which are stepped along the hull. It is possible this was done to strengthen the bottom of the hull when it was used as a water skiing boat and the fact this as a 2 litre power unit on a a sterndrive.

 

Restoration of a 1960's Tremlett speedboat

 The latest work on the Tremlett speedboat is the rebuilding of the dashroad before the deck is re-veneered with a 2 mm veneer of African mahogany 

We also have to reinstall the floor bearers which once we removed the floor were rotten and broken.

This deck beam is also the last top section of bulkhead to brace the end of the fore deck and stop any movement in the hull where it could twist 

The top section of the aft bulkhead and it also acts as a deck beam as well

Sometime in the past the speed boat was in the yard to have its hull repaired with a number of sections of the bottom being removed and then re-skinned 

Now the inside and the deck are being rebuilded so the boat can be used after a number of years being in storage.

Rubbing down the patch areas on the bottom of the Morgan Giles 30 and then giving the patches the first coats of Gelshield epoxy primer to build the protection up to the rest of the bottom

Having coated the patches with the first coat of Gelshield epoxy primer and then applied the epoxy filler it was time to go around the patches and sand back the filler 

This was done to each of the patches until they were smooth.

Some of the patches were largr than others because of the size of the pad on the cradle which the boat was on during its refit.

Once the patches were flatted back and wiped down they were given their second coat Gelshield epoxy primer.

Just got to have four more coats to be the same level of protection as the rest of the bottom.
