Hi Chaps,

Just looking for a few opinions on this subject.
I am about to start thinking about planking my build.
And looking through the build diaries, I have noticed
that some of you have filled between the ribs at the
bow and stern of the ship.

I can see the sense in this as it would give you more
surface area to glue the planks to. And will give you
a solid area to shape smooth before planking.

But I would really like to hear some opinions from those
who have, and those who havent, to help me decide which
route to take.

Thanks in advance.



Jim

hi jimbo,I'm one of the ones who hav'nt.as I have built a fair few,I've never had the inclination to fill in-between the ribs,I think it is a personal choice,and as it is a partwork build,you have more time to do it.so feel free.

Hi Jim, I agree with Karl here, though I have used balsa wood for filling the bow and stern sections of my build purely for the added contact area for the planks to adhere to...

As per what other's have said, its down to personal choice, and not forgetting that a 'filled' hull which has been poorly faired will still produce a poor hull profile.

Hi Jim! Cool

I'm one of the people who has used balsa, as it has been said

For a beginner fairing the hull can be a challenge in itself and filling the bow and stern can help, shaping from the centre to the bow or stern using a file then a sanding block to finish the shaping. This gives you the profile of the hull a lot of people are scared to remove too much from the ribs when fairing the hull or take end up taking too much off changing the shape of the hull altogether.

If you get the right shape of the hull before planking and it feels smooth then as you are planking if a gap start to grow between the balsa and the plank then you know you've not shaped the planks correctly, some people just kept on packing the gap on the ribs to fit the plank. Not fitting the plank to the hulls ribs. Another point is adding balsa adds strength to the hull, I've even added a row of blocks along the keel so the keel would stay straight when planking.

I've been blind once in my life and am losing my sight again, so I use other methods to get things right, a lot of my work is done by touch filling the bow and stern helped me a lot!.

It's up to you how you work! there is good points to adding balsa at the bow & stern, it can help you get the shape of the hull right, greater surface area to glue the planks, strength and keeping thing's straight, but it's not the way for all, it take time, money and you never see it when the hull is finished.

I did not fill the gaps between the ribs and I had never planked a hull before. If i was starting again i think I would fill the ribs but only at the bow. this is the area most people struggled with overlapping planks (clinker) and I think having the continual shape of the filled gaps could help with getting the shaping correct, indeed may actually save planking time in the long run.

Thanks everyone. Some interesting points there to think
about. I was leaning towards not filling. But I might
fill the stern, because of the complicated bending to go
on there.

Thanks again all.

Hi Jim

I belong to those who did make some balsa-fillings.
Made it much easier for me to chamfer the hull and sand a smooth "swing" into it. Especially at the bow section.





It worked for me.
