I finally finished some windows. I used bondo body filler and it turned out good:
I primed some walls with drywall primer. Drywall primer has a lot of glue in it and penetrates plywood very well.
I added aluminum angle (2"x2") around sludeout opening:
I was thinking about what kinda rollers to use in the front of slideout (indoor edge). Finally I decided to use a bunch of skateboard wheels. Skateboard wheels are not to hard, not too soft, durable, have good real bearings. The original wheel size was 52 mm but it was too much. I turned them down to 32 mm:
I simply put them on a long bolt and cut them using lath:
Here are all 8 of "low rider" skateboard wheels:
Last 2 I cut at much higher speed and they are super smooth.
I took 1.5"x1.5" angle and cut some notches out to install wheels:
Welding near plastic wheels was a lot of fun. I used a lot of water and a rag to cool them down.
I covered rollers with another angle and welded it. Now I have 13 feet 1.5"x1.5" square bar with 8 rollers inside. The rollers stick out about 1/4".
Today my goal is to install floor.
