Timberwolfy 62 Posted May 28, 2018 Share Posted May 28, 2018 I resisted a lot of really bad jokes for the title... So, I posted about this last year (http://crew.org.nz/forum/index.php/topic/14945-reinforcing-mast-base/) and promised everyone it was the next thing on my list to repair, and here I am making good on that promise, 7 months later... To recap quickly: my mast has compressed the spine of my kauri boat and is modelling itself after the leaning tower of Pisa. It makes for interesting pointing. I got a lot of great advice in my last thread and have opted to cut out the compressed wood and replace with a new piece. But... I don't know where I can source the piece of hardwood from. Its dimensions are 25x140mm and I'm guessing anything over 500mm in length will do? (pic in the original thread; obligatory, "metric system is hard, base-12 measurements for life, USA-USA-USA," goes here). I've found a couple websites for wood recyclers (kauri warehouse was one), which I'd be happy to use if it will work. No qualms about buying new; I just like recycling New or used, I'm not 100% sure where to purchase the materials and would appreciate your suggestions! Thanks! Quote Link to post Share on other sites
TimB 7 Posted May 28, 2018 Share Posted May 28, 2018 Lizaloni Are you in New Zealand?? Try and find some Eucalyptus, bluegums such as saligna or botrioides would do. Alternative is River red gum, or spotted gum. Can sometimes get this as decking timber at Bunnings, Mitre 10 etc Could also use tropical hardwood also sold as decking. just machine the grooved side flat and laminate with epoxy to get the required thickness. coat with epoxy for protection. Don't use Kauri, it is too soft. NZ timbers such as Matai or even heart Rimu would also do. Can sometimes be found in house recyclers yards. Tb Quote Link to post Share on other sites
marinheiro 352 Posted May 29, 2018 Share Posted May 29, 2018 Jarrah from Australia is another good option Quote Link to post Share on other sites
John B 106 Posted May 29, 2018 Share Posted May 29, 2018 Jarrah was my first thought too. Go to Rosenfeld and Kitson and select a bit. Mt wellington. Perhaps a call to a wooden boatbuilder to ask about grain orientation. My gut feeling is just flat sawn but I'm not sure, maybe quarter might be better . I don't know the answer on that. It might not matter. Once you know that its not difficult , you want timber you can get the length you need out of without knots or flaws, shakes/ splits. Quote Link to post Share on other sites
Fish 0 Posted May 29, 2018 Share Posted May 29, 2018 I resisted a lot of really bad jokes for the title... "metric system is hard, base-12 measurements for life, USA-USA-USA," goes here). What is this 'base-12 measurements'? I've never heard of it, I've only ever lived and worked in developed countries... Next you'll be talking about foot pounds per gallon or some such nonsense Quote Link to post Share on other sites
DrWatson 369 Posted May 29, 2018 Share Posted May 29, 2018 Second hand stores often have old oak or mahogany furniture that is past its best-before date. the front of an old drawer in oak might work (check it's not veneered...). Inorganic collection BBQ or outdoor furniture might also yield something. Perhaps a call to a wooden boatbuilder to ask about grain orientation. My gut feeling is just flat sawn but I'm not sure, maybe quarter might be better . I don't know the answer on that. It might not matter. I think I'd be tempted to go for quarter or rift sawn, primarily for dimensional balance. MCN Shipwrights (Hellensville) will likely have a small piece of suitable wood somewhere. Also, I assume that the old mast step is not an integral part of the keel piece? But rather a thickening or extra piece sitting on top of the keel piece? If it's part of the keel piece integrally, then you might want to consider scarfing the new piece in to avoid weak spots at each end of your mast step where it joins the keel piece.

Steve Pope 243 Posted May 29, 2018 Share Posted May 29, 2018 Teak? Try BBS timbers Whangarei all sorts there. Quote Link to post Share on other sites
Chewing Gum 17 Posted May 30, 2018 Share Posted May 30, 2018 Back in the day of cold moulded Kauri boats a lot of boatbuiders and designers specified Iroko for keel floors,rudders, skegs etc. Hard, tough timber. Quote Link to post Share on other sites
waikiore 397 Posted May 30, 2018 Share Posted May 30, 2018 Iroko is the pick of them, (rated more durable than Teak by Lloyds because of the high silica content) BBS usually have good stocks. Quote Link to post Share on other sites

Priscilla II 375 Posted May 31, 2018 Share Posted May 31, 2018 Leo has a website.http://sampsonboat.co.uk/ Impressive young chap but Tally Ho is a mammoth undertaking and the parrot will be old and grey well before what remains of her if anything hits the water. I have chucked him some coin as I applaud his enthusiasm. Quote Link to post Share on other sites

Frank 157 Posted June 1, 2018 Share Posted June 1, 2018 Rosenfeldt and Kidson have Iroko, its not particularly expensive for an exotic hardwood, I used it to replace some teak grab-rails Quote Link to post Share on other sites
ex TL systems 63 Posted June 2, 2018 Share Posted June 2, 2018 I have a young kauri tree that mysteriously died in my garden about 200mm diameter and 4 m long is it worth putting aside as timber seems a shame to cut it into firewood Quote Link to post Share on other sites
ex TL systems 63 Posted June 2, 2018 Share Posted June 2, 2018 Yes quite a few down here I planted all mine and one is about 10 M after 20 years so faster growth than expected plus we are only 50m from the sea. Used to put seaweed juice on everything but stuff just went nuts. Quote Link to post Share on other sites
