The internal hopper divider is made from 2 parts, the lower part needs folding to shape. You're asked to scribe a fold line to help form the top, for this I used an engineers scriber followed by a 'scrawker', which can be seen in the photo below;

As the angle would be less than 90 degrees I deliberately scribed the fold line so that its on the outside of the bend.

The lower part is a sloppy fit in the hopper, resulting in gaps;

Better this side;

Not my neatest work I'm afraid, more cleaning up to be done and it will be filled later, and anyway it will be mostly hidden.

If I'd fettled the part to try and achieve a closer fit, removing material from the edges of the etched part, it would have made divider too small. Its already slightly undersized as it is. The top part of the divider was a much nicer fit however.

The hopper side ribs are, as I've stated before, the wrong angle for the modified hopper body so a little gentle piercing saw work is required, the cut can just be seen on the inside of the angle;

This allows the angle to be closed up to match the hopper side, unmodified rib in the foreground, modified one behind tacked in place;

There's twelve of these to cut and solder in place...

188 degree solder and the Antex used again.
