Hello everyone! Got my parts ordered this evening and also got some balsa wood and plaster cloth. I was able to start work on one of the two tunnel portals for the hill in the back corner.
I started by drawing out the dimensions of the portal. These portals are going to have a square openings and multiple wooden supports. With the dimensions sketched I cut out the center to create the portal opening.
I then drew out possible support beams. This was the end result.
With an idea of how I wanted the portal to look, I began replicating the sketching with individual balsa strips. I was able to produce every beam but the two angled supports in the far upper corners. Instead, I put two secondary beams up against the center angled beams.
There may be a few more pieces I will add to it before I stain it. As of right now, here is a final photo of the portal in its soon to be home. Looks good so far!
