[6] How I removed frames and red lead from an old sailboat

- This surely was not the funniest part of my restoration work: Removing 82 wooden frames and ugly and probably harmful red lead from the inside of the hull. After 401 days (210 working days) this video shows how far I got. I am no professional boatbuilder and this video is just part of my diary - no instructional video.
In some comments there were concerns about me exposing myself to dangerous dust. Let me tell you that I used respiratory protection all the time and the air in my workshop was kept as clean as possible by an air filtering system when I was scraping or sanding. And yes, as a medical doctor I know that you should not even expose your skin to lead - no matter how dry the dust may be. As I said: this video is to show how I have done it - please don't try this yourself.

Your method seems very effective. I will be inspired to restorate mine (old dragon 1957)
I'm very pleased to read that. Please let me know when you get started ...
Dlaczego nie usuwa Pan do końca miedzianych gwoździ z poszycia?
I am sorry, my Google translator does not give me a reasonable translation for your question. So I cannot answer.
@@vonhier No, Im sorry: "Why do not you remove all copper nails from the boat deck?"
@@tadeuszbrt The Planks are made of European Larch (Larix decidua). The wood ist very durable but after 80 years also very soft. The heads of many copper nails on the outside are stuck within the surface of the wood. To remove them causes severe damage to the fibers of the wooden surface. Therefore I decided to leave may (not all) copper rivets in place.
@@vonhier I understand.
Previous frames were solid wood? Will the glued frames be more susceptible to water damage?
@@tadeuszbrt I don't think so. Prior to my own restoration I inspected many boats with frames like this. The oldest dragon with glued frames was over 30 years after the repair - still no significant damage. The glue (in fact it is a resin) may serve as a barrier and separates the wooden layers from each other. There must be no UV-exposure of the seams so that the seams won't crack - but frames normally are not exposed to UV.
Great video but... Airborne dust from red lead paint is very toxic. Even after the dust has settled out of the air, you can still get lead contamination, from rubbing your hand along over a flat surface where the dust has settled. For safety's sake, I would definitely recommend giving your work space a good vacuuming.
Yes. While doing it I wear a respirator - and two dust collection devices run for several hours. Vacuuming is mandatory apart from these precautional measures.
Thanks for your warning.

In fact: There is 1cm foam under the sandpaper just because the hull is curved. I admit that it is hardly visible, but it is there. The disc is made of rubber and therefore flexible without foam. Thanks for watching and the comment.
Those days it was normal painting wooden boats with lead paint.. Red colour isn't extra chosen. It's how lead looks like mixed with linseed oil!
It has several extraordinary qualities. Maybe the reason your boat survived that long without rotting away..
Toxicity is mainly by working on it, - like you do without any precautions 🙈
Nope. The precautions were: Two heavy duty air suction devices to remove dust instantly during sanding, vacuuming after sanding, changing workwear on a daily base (no sealed overall), respirators when removing the red fraction of the paint. I must admit: skin contact could not always be avoided completely. Unfortunately old boats die when the seams get leaky and as a consequence swelling and drying planks cause the frames to crack. Thats what has happened to my boat some 20 years ago. Lead paint obviously could not stop this - but you are probably right, maybe the lead and linseed oil slowed down the process at least for the planks, but not for the frames.
Ulrich Koch According to law dust is to be sucked away direct at the machine..
Frames doesn't necessarily break bcs of leaking Hull.
Leaking seals is an issue bcs of wood drying out after swelling. Maybe defects from frozen wood compressing the sealing as well.
Wood can (& often should..) be stabilised effective by ongoing soaking linseed oil, depending of quality & sort..
Lots of traditional sail boats wasn't build to last.
They were often light construction build as "toy" for wealthy men.
After some +30 years defects is prescribed.
Frames will not break by stretch. 3-4 millimetres isn't enough to pull oak in that dimension apart.
More likely bcs of longitudinal forces during a long time in ongoing demanding environment.
An all to often ignored fact is the major loss of strength in wood above some 20% moisture..
Try measure level of moisture in the construction during the season.
Try apply raw linseed oil & notice how much will soak in..
