Yeah I copied that same technique. Too smart to pass that up. I made mine by traping two pieces of card stock together. Marking a center and marketing the taper over the distance I wanted. Then I marked and punched holes every inch using a price of rubber mat under it and a flux brush flipped upside down.
Hamish:
Does that template allow you to layout along a snakey/wavy centreline, because It looks like a regular template that you might use for a straight grained stave???
For wavy staves I usually just draw the limb shape I want on a sheet of thin mdf, or scrap of plywood. It has a centreline, and lines perpendicular every inch.
I mark out along the wavy centreline of the stave in inches, then rule perpendicular lines every inch, to match the drawing. Then I transfer the measurements from the drawing onto the stave with a pair of dividers. Hey presto ...an accurate layout on a wavy stave.

This sounds sort of similar. It is a straight price if template and could be used on a regular stage but it has a centerline and holes punches every 1" so you can see through the template aligning it with the center as you work down. Picked it up from watching Clay Hayes make a snakey bow

No pictures that would show much today but I did take it down to 1" of width. Everything was perfect until right at the end I should have stopped but I had a bit split off the top. I think I can make do though.
I also traced out my tapers. 3/8 to 1" over 18" and I traced out my handle at 4" with 3" tapers to w thick ess of 3/4 as a preliminary. Plan to leave a good crown on the belly.
lenador:
Well as I worded my way down to the size on the width and thickness I realized I made some mistakes.... or learned some lessons I should say.
1. Is I should have taken more care recognizing the grain because this is the main reason I kept taking deep chunks out of the sides. I misinterpreted the grain and I'm not sure if the bow will like that's.
2. I took most of the width out of one side of the bow rather than splitting difference and side the stave was so skinny from the start I have drying checks on one side of the bow.
Additional to those I also found a check in the belly. At this point I'm. Going to finish it how er it comes out. So far it's been a good learning tool.
