<p>I use thinner timbers then plans. In Tiki 30 wharram recomends 2 timber with 2,5cm, I use 4 x 1,25cm . is more easy </p>

<p>I was much happier with the result, which I also think is stronger without the induced stress points of the saw cuts. Neither heat nor water was needed to do these bends.<a href="http://storage.ning.com/topology/rest/1.0/file/get/1930093467?profile=original" target="_self"><img width="721" class="align-full" src="http://storage.ning.com/topology/rest/1.0/file/get/1930093467?profile=RESIZE_1024x1024" width="721"/></a></p>

<p>I made one attempt to build the gaff per plan and didn't like the results I was getting. I decided to go with a bent lamination. I ripped a piece of Douglas Fir into 8- 3/16" x 2" strips and laminated them on this jig.<a href="http://storage.ning.com/topology/rest/1.0/file/get/1930093718?profile=original" target="_self"><img width="721" class="align-left" src="http://storage.ning.com/topology/rest/1.0/file/get/1930093718?profile=RESIZE_1024x1024" width="721"/></a></p>

<p>My gaff was glued from two pieces of timber. I cut slots lengthwise into the forward part of the gaff timbers (the part which needed bending) which made it easy to bend and glue. Use a piece of thick plywood (12mm), draw the gaff onto it, bolt blocks along your drawn line and clamp the gaff to these blocks while the glue hardens. I did not need to steam bend any piece of the gaff.</p>

I ran into the same problem, steaming did not help much, anything above 8-10 mm wooden strips broke, therefore I had the gaff laminated out of more strips.

<p>Hi Martin</p>
<p>If you are using solid timber for your gaffs to get the bend, you are probably going to have to steam them, even if you are using fairly thin laminates. I used a pot half filled with water over a gas cooker and put a couple of holes in the pot lid so that the steam can escape. I put a towel over the gaff jaw to help keep the steam 'trapped' for as long as possible.</p>

<p>I made a jig into which gaff jaw was clamped to help induce the bend. I left if for a day after steaming to let it dry and take the bend. Then I could see how much 'springback' had occurred. Then I glued up and clamped it back in the jig. Very little springback once glued.</p>

<p>Martin,once you have split the jaws,only glue them once you have separated the jaws with a piece of wood,when making my gaff i used 6mm ply laminated on the outside of the jaws.</p>
