Default Next up, the timid turtle

Now that the ducky is done, I'm going to try something a bit more complicated. I'll provide a running commentary on this one.
This is Timid Turtle. A rotund fellow he is, at approx. 7.5" wide.

According to the book directions about drawing scale, anything marked as being 57% must be increased in size by 121%, 3 times. So, .57x1.21x1.21x1.21=1.01 (approx.) so I used a drawing program to copy the shell and base to new images, increased those the required amount, and printed them to give me full scale templates. I can supply those if requested.

So now, it's to the wood pile to pick out the right piece for the shell. The grain should run lengthwise to make it look good. I'm going to use cherry as I still have some of that left.

Here are a few scans. A little large in file size at 419 to 876 kb.

Mike looks like a fun project. I will save this one for a future project. Now that I have a son getting married, perhaps there are grand kids on the horizon.

Cute.

It's not clear from the drawing, but I assume the connector pins for the head and tail are offset to create the movement?

Yes Ralph. They are 3/8" holes drilled 1/2" off center. The head and tail dowels connect through the part and both wheels. There are 3 axles for the front and back sets of wheels. Wheels are 2.25" and all axles are 3/8".

Looks interesting Mike. Making kids toys and furniture is so much fun.

Yes, they are Mike. Especially when you watch them pulling the toy around.

Today I glued up a couple pieces to create the shell and started on the chassis and wheels. Pretty simple. The chassis is 3/4" X 1 1/4" X 6" with 3/8" holes drilled 1" from each end and one in the middle.
After resawing a piece of cherry to 5/8", I used a hole saw to cut out the wheels, strung them on a 1/4" threaded rod, and used the sander to smooth them off. Holding the wheels against the sander on an angle, they spin and get sanded evenly.

The chassis is dry fit together. I used my combo square to find the center lines of the front and back wheels, then moved that line 1/2" where I drilled the crankshaft holes for the head and tail to connect.
I had a slight screwup where the frame center holes were supposed to be drilled 1/16" above centerline. To fix it I just opened them up to allow for movement.

Default The shell game

Time to work on the shell.
It isn't hard to cut out basic shape and angles of the top, but what takes a steady hand at the band saw is cutting the openings for the head and tail.
The blank for the body is 2" thick. I used the table saw to cut the outside shape.
Set the BS table at 40 and snug the fence up to the blade. Cut all 8 sides.
I then set the table on my sander to 40 and smoothed the sides.
Next, you draw the cut holes on the ends for the head and tail. I suggest you cut a 2x4 piece at 40 for practice. This is not the easiest part of the project. You have to remember that you are cutting a lot more wood on the bottom than the top. Basically, you are cutting out a cone.
After the cuts were made, I used the spindle sander, still at 40, to smooth the inside of the shell.

Default Head, tail, and feet

These small pieces are easy. Just trace the full size template to the 3/4" wood and cut them out. A 1/8" roundover bit in the RT took care of the edges, and a little sanding finished them. A 7/16" hole is drilled to go through the crank axles. I have some sanding to do on the wheels and chassis before I glue it up and mount it to the frame, that I have to start all over again. That part was my kick back mishap.

Default Base plate

To make the base plate, after zinging the first one across the garage, you cut the piece with 45 corners and cut the piece in half. That is so you can band saw the inside cavity out, then glue it back together. Clean everything up with the spindle sander, and round over the edges with a 1/8" bit.

I put it all together using screws instead of gluing it. First I mounted the chassis to the base, the shell to the base, and the feet will be screwed to the bottom if the shell.
