hi all..maybe i have missed something..but why is it not wise to glue the ribs yet surely if you set your jig correctly and as you slot the ribs into the keel they fit and are square and clamped then wheres the problem...been bothering me for a while...thanks paul

I would guess that there will be lower deck that is fitted at the same time. Would probably help to keep everything true?

Any experienced builders like to comment?

You should not be gluing any of the frames in place except the very first one. The reason for this is that its important to make sure that everything lines uo and is straight and true otherwise you end up with a twisted frame.
To prevent this happening, one of the ships decks will be used to help keep everything rigid. You will need to be able to align the frames with that deck so that the deck sits flat and true. The deck will help you to correctly align the frames. If your frames are not all properly aligned and you have glued them to the keel, your deck will not be flat.
Everything will be out of shape.
So wait until you are instructed to glue them to the keel, by which time you should have the relevant deck sections.

Ditto that Dave, the lower gun decks are used to align each frame exactly, certainly each mag so far has advised not to glue any frames into the the keel other than those at the bow.

Started putting Victory together yesterday after receiving issue 10 and the stern end of the keel frame, and as the instructions clearly state that the ribs should not be glued yet, it does not state why, but looking closely at the accompanying DVD and the installation of the lower deck clearly plays a big part with alignment...it was the same with the Del Prado Bounty build where I almost fluffed up due to the same reason...Blushing

Hi shipmates!BigGrin

The ribs shouldn't be glued yet, as by the time you get the lower deck part the glue will have set fully and there will be no give. Assembling the bow is ok! as is putting the internal keel together is ok! even glueing the ribs together is ok!, but don't glue the ribs to the keel until you have all the ribs & lower deck.
Then when you have a full day to yourself start to glue the ribs into place keeping them at right-angles clamping them in place for 30 minutes before moving to the next. When all the ribs are fitted place the lower deck in place to hold the ship square, the glue should have enough give to fit the deck with ease.

Please only use PVA glue not the fast set type of PVA and no super glue,Unsure REMEMBER NO SUPER GLUE!

I'm still working on the final design for the jig as I want a jig that can be used as a building slip, a planking support and used as a ropewalk. I just want it all a multifunctional jig, the first attachment for keeping the ribs square as the glue sets is almost finished. The attachments and keel support brackets will fit into two routed channels, I also have two wooden clamps (tapestry clamps) which can be screwed to the base for planking.
The ropewalk attachment has been held up as I'm waiting of the last gear to be sent as the supplier ran out of stock. Mad

Good Luck! shipmates! ThumpUp

Very important guys.......

Don't do any shaping to the keel along its full length (including at the bow)!

The way the model is planked leaves the width of the keel exposed along its entire length, so that later on an external keel can be added to what should be a flat contact edge of the already installed keel, obviously when the time comes the hull frames will be chamfered to suit the lie of planking along the hull.

I second you on that advice Tomick, began my build yesterday, and the only thing glued are the bow formers. All the shaping will come much later when all the frames are eventually glued in place, which adds to its rigidity when it comes to forming the hull's over all shape, and of course make way for the real keel...ThumpUp

Hi Just wondering when we eventually get the lower deck would it no be easier to do (as i have seen in other builds) a 70/30 pva mix and paint it on to the frames/keel after we have fitted the deck? this would ensure there will be no problems with fit etc.
