Where on the web could I find out how to make a wooden wing chun trapping dummy?? - blueprint of wooden swingset

I looked to buy a wooden dummy and trapping JKD as 500-600 dollars, so I'm with a friend who is very good with pieces of wood and I'll pay $ 150 to use for me, I do not find flat on the Web, with the exception magazine.com Kung-Fu and is not working, so I guess no help.
