Well the wife posted the pictures before I wrote what I wanted
Pic #1 just shows the frontal view. The trays on either side of the arm supports are for the supply of bullets and checks. The last 2 pic show the stored supplies.
Pic #3 Is just the back side of the box. The opening in the back is for a tray to catch the checked bullets that fall through the top.
Pic #4 Shows the arm that presses the bullets into the checks. The three holes are for adjustment on the arm so it sits as square on the bullet as possible. The white piece of high density plastic used for its sliperieness. The #7 indicates it has a hole drilled in it to slip fit a 7mm bullet. The nail is what the arm pivots on.
Pic #5 Just shows the plastic piece in place. You can see the thin metal plate that the white plastic slides on, an gives a hard surface for pushing the bullets against. The 2 inked areas are for alignment to push the bullets through the box top into the tray below.
Pic #6 Is a side view of the pivoting arm in place.
Pic #7 shows my device as I am applying the checks. First I use one of the fingers on my right hand to slide a check into the hole in the plastic and letting it drop as far down as friction will let it slide. With the same hand I pickup a bullet and drop it into the hole nose up. Because the hole is drilled for a slip fit. The check and bullet are self aligning. I then bring the arm down to contact the nose of the bullet. Then press down on the arm to seat the check onto the bullet. In most cases you can feel the check seat onto the bullet. I then raise the arm to perpendicular. Slide the white plastic piece towards the rear of the box until the bullet is between the ink marks, and then push the bullet down through the top of the box into the holding tray below.
The only part of the build that is critical. Is to get the 2 trays and the white piece of plastic close to the same height.
