Guest 000 Posted May 15, 2016 Share Posted May 15, 2016 Looking at this stitch and tape construction for small boats, where wire is used to hold joints until the adhesive hardens and is then removed. Why does every designer specify copper for the ties when florists wire can be had at the same gauge, strength and flexibility but at a fraction of the cost? Is there a reason for using copper?

erice 732 Posted May 16, 2016 Share Posted May 16, 2016 a couple of advantages of copper wire - wrapping it around a soldering iron causes it to quickly heat so it breaks the epoxy bond and can be cleanly pulled out with a minimal sized hole - soft enough not to cut into thin ply if over tightened and can be more easily retensioned if required to keep the edges fair so if you've got it use it if not other wires and ties can be used with a little more care Quote Link to post Share on other sites

Guest 000 Posted May 16, 2016 Share Posted May 16, 2016 Cable ties! What a great idea, hadn't thought of that one. Going to give it a try. Sick to death of Chinese deflatables with their limited life so resurrecting the molds and templates that I have for a 2.3m nesting clinker praam and going into production again. Plan to build one for me and a few extra and see show they go on TradeMe. Quote Link to post Share on other sites
waikiore 399 Posted May 16, 2016 Share Posted May 16, 2016 Have used cable ties for many years with great success- they are a lot easier on plywood and planes. Quote Link to post Share on other sites

erice 732 Posted May 16, 2016 Share Posted May 16, 2016 "clinker pram" uh oh missed that first time round clinker beautiful but far more labour intensive than a box Ken if you read this this, weren't you looking at making a ply nesting dinghy? Quote Link to post Share on other sites
erice 732 Posted May 16, 2016 Share Posted May 16, 2016 maybe won't even bothering torturing the ply not only is that a gross violation of the rights of plywood it seems totally out of fashion Quote Link to post Share on other sites
Guest 000 Posted May 16, 2016 Share Posted May 16, 2016 Check out the Eastport Nesting Praam by Chesapeake Light Craft. I have had a set of plans for a while and have templated every part in 3mm MDF to facilitate semi mass production. I haven't built this particular dinghy before but think it will be suitable as a tender for a smaller cruiser. I am an avid builder of traditional clinker dinghies and imagine that marrying traditional design with modern materials and construction techniques should produce a very satisfactory and pretty alternative to to those darned deflatables. Picking up a load of ply,glass and resin tomorrow. Giving myself two weeks from go to whoa. Quote Link to post Share on other sites

GregW 28 Posted May 16, 2016 Share Posted May 16, 2016 Don't use wire. Cable ties are much less hassle and plane right off. Welsford Seagull I built back in 2005. Quote Link to post Share on other sites

Clipper 343 Posted May 17, 2016 Share Posted May 17, 2016 Ken if you read this this, weren't you looking at making a ply nesting dinghy? I'd like to. I quite like the woods duo design. Very slowly working on a 4' dinghy for my daughter at the moment. Quote Link to post Share on other sites
Black Panther 1,587 Posted May 17, 2016 Share Posted May 17, 2016 If anyone is interested in a Welsford Joansa I have a partly planked up one in the basement I need to get rid of before we sell the house. Quote Link to post Share on other sites
John B 106 Posted May 17, 2016 Share Posted May 17, 2016 I built 4 kids dinghies for my three, they're all redundant now. The first one was a lemon, the second a bit better and the third and fourth Des Townson complimented me on, which I appreciated.He wasn't exactly known for mincing words, He told me at length how he disliked our first yacht , but then spent a lot of time telling me how after much consideration , Laurie Davidson got it absolutely right with our second( Ha!) But those little boats were absolutely thrashed by my kids and any other kid in our cruising group. Hard worked little boats, very rewarding seeing the kids go all independent in them.

rossd 16 Posted May 18, 2016 Share Posted May 18, 2016 I build a Joansa a few years back now, only draws 90mm , still havent build oars , my advice now is to build the oars first ! Clipper that looks like a Welsford "Roofrack" I am building one as in theory it will fit the foredeck. I am making the short light model 1850 long 4.5mm thick ply. I have made the top panels over height so I can scribe the foredeck shape on it when upsidedown so it can be tied down snug. The gunnel might look a bit odd in the water but who cares. Weather there is in reality room for it practically on the foredeck time will tell. Quote Link to post Share on other sites
Fish 0 Posted May 18, 2016 Share Posted May 18, 2016 I'd like to. I quite like the woods duo design. Very slowly working on a 4' dinghy for my daughter at the moment. Hi Clipper, What do you call that dinghy, and where do you get the plans from? And also, what would be an appropriate age to start kids in dinghies (buy themselves)? I've been pondering making a dinghy for my kids, and my three year old likes the look of your one. She says she would sit in the middle, and her little brother can sit in the front (might help I showed her it and asked if she wanted one....) She likes rowing our deflatable, but its way too big and we don't actually go anywhere. I'm keen to make a 'kids sized' dinghy, just for her that she could actually row buy herself. Attributes I'm after is suitable for 3-5 year olds to play in, quick for me to build, suitable bottom shape to allow playing on the lawn without damaging the boat, and, I might be dreaming on this one, but small enough to fit in the boot of the car would be a major bonus (thinking I might need a very small nesting one to achieve that attribute). John B, I'd be interested in your thoughts on what works. I'm also thinking ahead for when my 1 year old is big enough to play in his own boat too, its likely his sister wont want to share...
