hi all, Just started to sand the hull and not sure how far to go,do i get all the marks out and planks level, or fill some of the uneven planks with wood filler. Here are some pics to look at, please advise as to how far to go.I know everyone's differ. I know I am a bit away from that but wanted to know how you guys done it.  Thanks rob sandnesspeats attached the following image(s):

Hi Rob,
It's looking good so far.
Being this is the first time I've tried something on this scale, my hull didn't look much different to yours at that stage. As a general observation,if you are going to be copper tiling the hull, then using filler would be an answer, although the hull still needs to be smooth so that there's no obvious lumps and bumps and the tiles have a good clean run.
But if on the other hand you'll be painting or staining the hull then more sanding is required. You'd have to be careful with the use of filler because some brands will show through the stain. However, you'd be surprised how much those 2mm planks can take in the way of sanding - you could try using a smaller width sanding tool on the more obvious areas and a finer grade also. One can purchase a special sanding tool that's designed to sand around curves and awkward angles.
Again, looking at your photos, just as an observation, you'll need to be careful around the stern - it needs to be 6mm wide to accommodate the stern post where the rudder attaches.
Hope this is of some help and keep up the good work
Happy building
David

Thanks for the advice David very informative, . It just seemed a lot to sand (never having done this type of thing before) but what if I wanted to stain or paint and needed a few parts filled with filler does it show up underneath the stain, just a thought. I will see when I have finished sanding eh!! Thanks again rob

Hi again Rob,
Yes there is a lot of sanding to do but - (and there's probably something wrong with me for saying this ) - but it was part of the build that I really enjoyed doing as the hull gradually transformed from a lot of separate planks into a thing of beauty with all those gorgeous shapes and curves gradually coming into being. I'm really glad I spent so much time on this part of the job, it's given me a great deal of satisfaction and I'm sure you'll feel the same when you finally step back, sweep up all the saw dust (or whatever it is they call the particles of wood that come from the sanding process) and see what a grand old lady she is.
Incidentally, talking of filler again, if you hang on to those sweepings, they can be mixed with the adhesive you used to lay the planks with, and used as a filler, giving you a filler that matches the colour of your planks exactly and won't look out of place when stained.
Keep it up and happy building
David

Hi David,I have a good idea what you mean,I am not the most patient of people but I have had to on this project.  . You pointed out about the stern post,I checked that and it is just about 6mm,thanks for pointing that out  . So will have to be careful on that. I did save a lot of the sawdust as I will probably need it. Great help thanks. rob

just keep sanding pete. you'll know when you've gone too far when all you have left is a pile of sawdust. seriously it still looks like you have a bit to go. it's hard to say how much, but it took me around a week and a bit to get it how i liked it, a little bit every night. looking good though pete. however....................the real thing is nowhere near as smooth as any model. when i saw her last year the first thing i noticed was how uneven all the planking looked. Come on you Jimmies

Thanks saint,  Done a bit more last night and it is coming along slowly but surely. I was thinking of leaving it rough and ready,as you say the real thing looks uneven etc! That thought never lasted long though. ,even now mine feels nice and smooth and still a long way to go. cheers rob

The problem you will have is if the top surface of one plank sits below or close to, the bottom of the adjacent plank. That doesn't seem to be the case from your pics even though the surface looks a bit bumpy at the moment.
Use glue and sanding dust as filler for the moment and she how she looks when you are finally finished. I tend to avoid the chemical fillers if I can.

When I sanded my hull, I sprayed it with some Tamiya acrylic dull red. Once dry, I gave it a light sanding using a sanding block. Any paint left meant areas which required filling. So whacked on the filler, waited for this to dry, then another round of sanding. Again, a spray of the dull red, and another light sanding when dry. If there were any areas still filled with paint, then another round of filling until I ended up with a relatively smooth hull. Hope that helps. Be careful though, the wood can get quite thin and you're never really sure how much is left to sand through...

That was what I was afraid of going too far trying to get everything level, just have to take it easy Eh!! thanks rob

Hi guys here again  I was wondering if anybody has used this stuff before(photo) as you can see from the photos I tried the pva and sanding dust mixed, very hard to sand off and does not look ok! not bad but!!!!!, might have mixed it wrong mind you. This wood filler (natural) looks as if it will sand better and smoother without going too far, just wondering. Looks like painting after all. I will try and get the pictures in order. What do you guys think, grateful for your input as usual rob File Attachment(s): sandnesspeats attached the following image(s):

Hi Rob, I used woodfiller on my build as well. After sanding it, I gave it a coat of spray paint and that showed up another lot of imperfections so had to crack open the filler again - got a very nice smooth finish in the end. Just be careful of sanding away too much of the false keel, especially at the stern.

Hi Walter, Thanks for that. Nice to see that somebody is at the same stage as me. The only thing I am wary of is the stern, that has to be about 6mm for the stern post, I will keep posting pics as I do it. cheers rob

Hi Rob,
Thought you might be interested in what I did to solve the problem at the stern in area around the false keel as I had the same problem as you after being over-jealous with the sanding in that area. (In my case, I had sanded the false keel too thin to begin with, but what the heck, I'm new at all this and we're allowed to make mistakes aren't we )
The answer I came up with was to lay a second layer of planking over the first, using various lengths of off-cut planks which I proceeded to 'feather' in until they became a smooth run with the other planking and after more sanding to get the correct thickness for the stern post, the modification was hardly noticeable, the effect being as though I had added some extra 'stealers' at the stern. After three coats of stain and four coats of varnish the repair was imperceptible without very close scrutiny.
If you try this, make certain that you cut the (repair) planks to varying lengths following the lines of the curve of the hull in that area, and also, not too short (in my case, the lengths varied between 40 and 120 mm). The longer they are, the more naturally they will blend in with the main planking.
Hope this gives you some ideas to work with if needed.
Happy building
David

My thoughts exactly about making mistakes etc!!!! Hi David, Great idea I will certainly do this if mine goes too thin, Not quite there yet It is still 6.5mm but haven`t finished sanding yet  I will have a look at your build. cheers rob
