There's slow progress for the horse. Just haven't had much of an incentive to get it going farther than it currently is.
Building the body requires the legs to be somewhat fleshed out as well. Tubes have been glued over the screws to provide access points. They're all outside the horse this time instead of the cosmetically better looking underside/inner side of the horse. I'll probably be tightening them often, so it's probably for the best. The screw assemblies compose of a countersink bolt, spring washer, two washers and a nut. The nut is held in place inside the center of the tubes by strips 2.5 Magic cards thick, 2mm wide, forming a hexagonal housing to prevent nut rotation. These will be later plugged with a 110lb cardstock core so the nut doesn't travel axially, fully restricting the degrees of freedom. If this wasn't added, tightening the bolts would be tedious and difficult since there's nothing to hold the nuts in place.
Since I've opted for the neck to bend downwards, I need to conceal the gaps that result. Rather than make a giant rotating joint that resembles a LEGO horse, I chose to go a more difficult route.
At mid position, the edge of the upper triangular shaped cover piece lines up with the edge of the neck opening. The lower cover sinks inwards into the chest cavity, assisted by a set of hinges.
