back from the cold

by

The teardrop trailer is now back from the storage compound and sitting in the garage.  After taking the tarp off, I discovered some water damage to the hatch.  It was a cheap tarp, and the wind jostled the tarp back and forth enough to wear thin spots in it, and water seeped in.  I’m hoping it’s just a matter of sanding it away and sealing it again with polyurethane.  There is still much to do.

in cold storage

The teardrop is now wrapped up against the winter elements and in storage at the RV compound.  I couldn’t get it completed in time due to other responsibilities.  I’m not quite sure how the wood will fare the winter, but F and I wrapped it up the best we could.

There it will sit until spring.

final oil-based polyurethane coat

by

I’m working on the final coat of oil-based polyurethane for the cabinet doors, galley hatch, and berth doors as well as various wood filler spots.  I mixed 50% polyurethane (commonly called Varathane – but this time actually is), 50% mineral spirits.  This allows the urethane to penetrate the wood more.  I’ll sand all of it lightly and coat with four or five more coats of water-based polyurethane.

It’s a lot faster if you roll it on and then smooth it out with a brush later.  Rolling with a paint roller allows the polyurethane to penetrate more than with a brush but creates air bubbles and gives a rough texture.  Gently, slowly going over it with the wood grain creates a much smoother finish.

Yes, you can actually put water-based on top of oil-based.  It will typically bring out the colours and patterns of the wood more.  You just have to make sure you lightly sand after each coat.

I’m using an exterior, UV-safe water-based polyurethane.  It’s a little hard to find sometimes, but it’s better than adding expensive coats of UV block coating later.

no longer unhinged

by

Now to determine the placement of components in the hatch with the new design (speakers, latch / lock, pneumatic lift mechanisms) – I purchased from Home Depot two lifts, rated to hold 8-12kg, to be delivered within “3-16 days”.  The ones they had in stock were pretty little and thus unusable.  In the mean time, most of it can be framed in.

We used a piano hinge with rubber from a bicycle tire inner tube surrounding it.

I cannot afford US$100+ for a hurricane hinge.  I bought an RV hatch door from a dealer in town in hopes of using that, but it only had six screw mounting points to the hatch portion; not nearly strong enough.  So, this piano hinge with rubber will be good.

my new ribs

by

I posted this yesterday afternoon, then my server hit a snag.  I lost this entry.  I’ll enter it again.  It won’t be as eloquently, wittily, or interestingly put as it was before.

I’ve been back at work on the teardrop trailer (teardrop 1).  Floyd and I looked at length at the ribs I created for the galley hatch several weeks back.  I determined that they weren’t usable.

So, we created six new ones.  Now they’re up.  The framework for the galley hatch is up.

Teardrop 1 023 changed wall height, width

by

No pic here because there isn’t really anything visual to show.  I have changed the wall heights and widths to match a change in construction.  Rather than building the walls onto the floor, which would decrease the inner space width by a couple of inches, the walls are now to be built on the outside of the floor, resting on metal support brackets supplied with the trailer then anchored into the side of the floor structure’s 2×2 frame. This will add a couple of inches to the height of the wall, since it will sit lower.
