I wanted to do a video on making scoops but my camera is not set up for what I want to do so I’ll do it in pictures.
The first thing you need to do when making a scoop is to determine the volume needed and then calculate the dimensions needed . The Volume is Pi x R squared x depth. For this one the target is a 3/4 cup scoop
The volume of a cup is 14.437 cubic inches. 3/4 cup is 10.828 Cubic inches. I want a 3”ID scoop so the formula is
10.828cubic inches= ( 3.1416×1.5” Squared) x D Then D= 1.532”
Or if there is not a target, just figure on the size you want to make it and then lay it out on a block and make sure you have enough scrap at the end of the handle and the opposite end behind the scoop, and for the spigot on the bottom of the cup area after you turn the outside dimension.
I found this piece of real red box elder and was going to make a 3” scoop and have some scrap on top of the cup area for counterweight but I thought that wood is too pretty to turn it all away as scrap so I decided to make 2 scoops and glue on some other wood for the counterweight.
I cut away all the unnecesary wood and glued on the counterweitghts.
After the glue was dry, I put centers in the blocks along the center of the cup and the center of the handle .
I rough turned the handle just to make it round and then turn the bottom of the scoop to the final dimension which is 3 3/8”. I do this first so I have a target for turning the handle. I want it to be tangent to the body of the scoop.. I also put on a spigot to hold the scoop for boring the inside.
During the turning of one handle I found a crack clear through the handle so I had to stop and CA glue it to make it sound.
I finish turning the handles to size and then chuck the scoop by the spigot and part off the counterweight or cut it off in the band saw( which is safer).
Then I put the the scoop in the chuck and bore the inside to the required dimension. In this case it was 3” diameter x 1.532 deep. I drill a hole and then finish the entire inside with just a bedan.
After the inside is finished, I mount it on a jam chuck and turn off the bottom.
I cut off the nub that is left and sand the bottom with my 90 degree HF drill and Klingspor scalloped sanding discs.
I cut off the excess scrap on the band saw and sand the scoop to shape.
I finish the scoop with a food safe finish- like Belhandla salad bowl finish, or Butcher block finish or mineral oil.
