    I’m looking at that Dremel UltraSaw and the little Makita, which has adjustable cut depth and angle.

    I considered the Dremel as well. I’ve heard good things about it… but I ultimately took the cheaper route and got one of the Compact 4 1/2″ Worx Worxsaw (http://a.co/dYWJ58m). It did the trick and I think I paid <$50 for it.  Just another option to consider.

    So much sanding… this is my life now…

    Ended up applying the second coat of epoxy with nothing but an epoxy spreader. I only intended to use that tool to spread things out evenly before rolling and tipping, but just squeegeeing it on worked so well that I decided to call it good. This resulted in a thin glassy smooth layer with minimal waste. I’ll dust this with 220-grit and put on a final coat probably in the same way but also tip it with a brush.

    Oh, and I ordered the Worx saw. The 2″ cut-depth (for other projects), price, and plethora of positive reviews sold it.

    Dan, love your marine hatch, and like you I also dislike the standard roof vent approach. For me it is also a question of having limited height in my garage, so whatever I can do to reduce overall height is good.

    I am in the Pacific Northwest and will mostly be using the trailer in this area. I am thinking that I can also get by without a roof fan.

    Question: what are you doing for vents or fans elsewhere in your trailer? What is your thinking?

    Any other builders views on doing without the roof fan?

    @stretchmike, I’m also in the PNW (Portland). Maybe we’ll have to get together sometime.

    I got the hole cut for the hatch today. I’ll post photos after dinner. It looks like it’s going to be even better than I hoped. 😉

    Regarding airflow, I’ll probably go with two mushroom vents on the rear of the trailer with some high quality PC case fans mounted inside, over the vents. The marine hatch has a setting where you can lock it open about 1/4 inch for airflow. We’ll see how that setup does. I don’t really ever camp in the rain, so I’m not too concerned on that front.

    Ok, so got another layer of epoxy on… this time with squeegee then roller then tipped with a brush. Just doing the second coat with a squeegee wasn’t the best idea. Don’t do that. I’ve got some imperfections from that technique (mostly on the top and front of the shell) that would take a lot of sanding work to get out. Oh well. Good enough for now. I want to move on…

    Ooookay, so much progress this weekend! Got on another coat of epoxy (properly this time) on Friday. Cut out all the things on Saturday. Did some galley stuff on Sunday.

    So, the hatch. I’m super pleased with the hatch. I made one mistake by cutting the hole with square corners instead of rounded, but that will be covered up later by the supporting structure. It’s basically a flush-mount like I wanted. I’ll most likely be able to just finish the exterior with a fillet after I get the interior structure built. More to come on that.

    I was feeling a little stuck with everything being held up by glassing, but now there are plenty of different things to work on at once: doors, top hatch, galley hatch, galley finishing, interior shelf, interior finishing, etc.  Booyah!

    venting:  you will most likely want/need some venting.  we took the TD out a couple of times last fall, when the overnight temp was about 40, and I woke up in the middle of the night sweating and needed to crack open the roof vent.  there was enough convection due to the temp inside the camper  so that there was a bit of a draft coming in from the mushrooms so that it cooled things down enough to get back to sleep.  if you decide to forgo the roof opening altogether, I would think a pair of computer fans exhausting out of the front or rear mushrooms would set up enough crossflow to keep things cool.  the CLC insulation package really does its job!  but don’t be tempted to leave out the insulation, else you’ll get rained on due to condensation during the night.

    Oh, I’ll have venting. That top hatch opens and I’ll have those nice case fans over the rear mushroom vents. I will be fabricating a different insulation solution because I think the CLC stuff is too expensive and waaaay too dark. It’s dark enough inside there already. I’ll obviously post here when I’m to that stage, but I think y’all are going to like it. 🙂

    Dan, thanks for the updates and hatch information.

    You are @ 3 weeks ahead of me, so appreciate you “forerunning” these steps.

    Mike
