I now have 25 spoon candidates as shown below.
Associated with these are the cutout left-overs and there are 50 of them.
I do not want to throw them away. One way of turning them into something useful is shown below, but I will be dealing with this topic separately.
I will also be talking about a new discovery, which is the photo below. This may actually turn into something potentially very big, but again I will talk about implications of this discovery separately.
Above will be replacing what is shown below.
The problem with this 45 degrees flat bed is that the angle is not accurate enough. The angle adjustment mechanism with the PROXXON table saw above is much more accurate. I will talk about this amply later.
Now, let me go back to spoon candidates. These are still all flat pieces. Next step in the process is to pencil mark lateral profile on the side of the curved pieces. To that end you need a profile jig. For infants the profile at the bottom of the next photo is used.
Since this jig is placed on the side, striding across the valley it is made of a thick piece of wood, so that copied profiles are identical. You do not want it to bend easily as you pencil around.
In order to loose anything outside the marked lines the band saw is not used. Instead, a disc sander is used, as shown below.
This allows me to loose mass very quickly from the unwanted region of the spoon candidates. These roughly sanded pieces will be more finely sanded on the belt sander. The result is shown below.
I think you can actually see that convex surfaces are already there. These are still rough surfaces and a hand-held rotary device is then used to smooth them out.
What you need to do then is to hollow out concave surfaces. It is now my beer time, so I will talk about it in my next article.
