The right side after 1 pass with the wire brush.
I removed the centerline rollers. One of the brackets had to be removed, the bolts being seized I had to cut them out with a Dremmel reenforced cutting wheel. The roller bunks on the sides will be replaced with entirely new ones.
The big breakthrough was finally being able to tilt the trailer. The original Luger trailers have a joint about 4' from the trailer coupler. The tilting action allows you get the boat in the water without "getting your feet wet" according to the catalogue. In reality the tilt is useful and keeps you from getting your knees wet. The tilt action occurs naturally due to the weight of the boat. Once the bolt is released and the trailer on the launch the boat freely floats right off. I'm glad I will easily be able to recover this function.
I removed the stem next so I could remove all rust from the tilt bolt. The bolt came off easily and is soaking in a WD-40 bath. The crank was a lot harder to remove from the vertical post so I had to resort to the reciprocating saw. With the stem removed the trailer was much easier to handle so I flipped it upside down and removed more rust. After I scrubbed and rinsed everything with de-greaser to start to remove the WD-40 remnants.
Next I will have to epoxy the hull and in-between curing points I will be treating the trailer with Rust Bullet coating. Two coats of that and she'll be ready for a shiny new coat of blue paint.
Once the trailer and hull are done the project is half over. With new rollers, guides, crank and lights she'll look as good as new. The last thing I wanted to do was put a new clean bottom onto old black deteriorating rubber rollers. The bearings were replaced 2 years ago and they are still in great shape. The tires are also good and relatively new, I will need a new spare.
