I need to see some pics of what a tiller tree looks like and some instructons on building one
Here's some plans that Tim Flood drew up.

thanks dano, can anyone show me an actual pic of one, and how would measure pull wieght with that, how would you attach a wieght scale to it?
Ian
go to the Build a longs section and start going thru the bow buld alongs. For every bow build a long there is a tiller tree of some sort.

You can basicaly do whatever you want as long as it holds the bow level (so you can see the tiller) and has a way of pulling it.
Mine has one pully at the bottom and I attached a scale between it and the bowstring so any time I pull it I can see the weight. This helps so you don't over stress the limbs by pulling past you intended weight. Mine is attached to my bench.
I also built another one I can hook the string over a couple dowels and then step back and look at the tiller. No pullies on this one and you have to pull it down over the dowels by hand. I usualy don't use it to build because I don't like to be that close when unsure about a bow. The pulley is much safer.
Like I said it can be anyway you want to make it as long as it holds the bow level and stable.
Here is a picture of the one I use the most. It is along the same design as Dano's except I use a two pieces of plywood with rounded slots screwed to the side rather then a block placed on the front.

Hey Walt,
Would you mind giving a brief rundown of what all the graphics on the board are used for?
Bill
Bill,
I picked up the board from a sewing shop and use the checkered pattern to help me keep the limb tips bending the same distance or evenly. The other lines were on the board when I bought it and I haven't used them for anything. It also helps me determine, roughly, if the limbs are bending evenly. For final tillering, bending, and final touches I have started using Eric Krewson's tillering gizmo.
Thanks Walt. I thought you may have turned the board 90-degrees and compared the bending limb to the curved lines to check for flat spots or hinges.
Bill
what is his tillering gizmo?
Its an adjustable pencil stuck thru a block of wood that helps to identify flat spots in your tiller. Do a search in buld alongs."tillering gizmo"
I use a small block of wood and screw a screw in to it till the point just starts to come out it markes the wood to be scraped when tillering.
