If I had a grandchild I would love to make one of these because then it wouldn’t be piddling time anymore but we don’t have any yet. However, I was just in the shop making some rossettes for a customer and while I was doing so I got to thinking about this little walking duck. For anybody who happens by this thread and wants to make one of these this is the way that you could go about doing it and it would take away some of the experimentation. You would have to have a digital photo of the duck but this is readily available. You could import the photo into a program such as Corel Draw or any other vector graphics program and put this photo on the bottom layer for reference. You could then draw the profile over the bottom layer onto a second layer. This could be accurately done and wouldn’t take too long at all. However, your halfway there after doing this. This would also give you an accurate outline for the feet which are really a rocker when the legs are together. With the profile you would already know exactly where the stationary leg would go and how it would be positioned. With a second photo showing the back leg which is the one that pivots you would have two positions of the back leg. Assuming that the pin for the back leg is in line with a center line of the back leg (and I bet that it is) then you could draw a line through the center of the back leg in each position and you would then know where the pivot point is. In the program you can copy and rotate the profiles and position them in several different positions and from this you could get the outline of the cavity that would have to be created for clearance so that the back leg could freely move on the pivot. I would assum again that the top of the pivot leg would be a circular arc because it just makes sense to do it that way. This arc would be part of the cavity.

At this point you could go ahead and cut out a profile of the body halves and make your best guess from the picture how thick to make the legs. The halves would need to be routed out for the stationary leg and the stationary leg would just fit into this rout and would be glued. You would also make the clearance routs in the halves for the back leg and then drill the pivot hole.

There would obviously be a little guess work and experimenting but I don’t think that it would be a whole lot of guess work and the first one that you did would probably work but maybe not perfectly. From observation I think that you could use an educated guess by it’s behavior as to what changes you could make so the second one worked better. After the third one I believe that you would have the bugs worked out. Then you could make a number of these for all of the children that you know.

From lew's video you could figure out the size from the man’s hands and adjust the vector drawing accordingly.

These directions are off of the top of my head and thus are overly simplified but I think that you get the picture. The vector graphics program and the digital photos would make it fairly easy to get close on the first try. Also watching lews video several times would make all of your guess work a little more accurate.

The other way to do it would be to order one and just copy it but that would cost some money and a waiting period to get the duck by UPS. Some people would rather just try to figure it out because that can be fun too.
