Finally got far enough with the CAD model that I can start sharing.
Additions:
- Guide arms to make sure each strip stays aligned
- Guide plate above the channel on the "ramp"
- Makes sure the two strips are pressed together as you pull the carriage down the trough
More info in replies.

Comments
- acts as rails for carriage
- lower strip of foam rests against floor of trough
- 3.5" wide channel
Image 2/3: Carriage
- slides along trough
- ramp mounts on front
- heat gun mounts on back
- 2nd strip of foam rests against this
- opening for heated air to hit foam on way to bond location
Image 5: Ramp Standoffs
- serve same purpose as trough walls, but for 2nd strip
- act as mounting points for crossbeam
- keep strips of foam aligned horizontally
- rest "loose" between ramp and crossbeam, clamped by beam
- 2nd foam strip is threaded between this and ramp
- clamps guide arms in place
- acts as mounting point for bond plate
- bolts stick out of standoffs with springs on them, wingnuts to adjust tightness
- brings the foam strips together and applies even pressure
- adjusts via sliding up and down on bolt using channel
- tighten wing nut on bolt to fix in place
- a heat gun would be mounted on the open space of the carriage, with the nozzle aimed at the opening between the carriage base and the ramp
- the faces exposed to heat would be coated in heat resistant/reflecting materials
