Re: GT27 Build (Wes K)

Thanks for the feedback. I'm a lucky guy indeed with a wife who helps! (And daughters too!) I have one layer of 9 oz. glass on the shower pan currently. I'll give it three coats of epoxy after installation as well. I trust that will suffice. We only anticipate occasional and very short ('navy') show...

Re: Preparing for GT27 build - questions

That's what I thought based on the apparent scale of the drawing. Thanks for the confirmation! I'll plan for three longitudinal battens, 1x2 nominal.

Re: Preparing for GT27 build - questions

The plans don't include scantlings, but just judging by scale, it looks to me like the longitudinal beams are maybe up to twice the height of the 1x1 cleats used to trim the tops of the floor frames (see below). Maybe 2" tall? That's why I'm hoping Jacques will provide clearer guidance. I don't have...

Re: Preparing for GT27 build - questions

Jacques, just checking in again: What are the scantlings for those longitudinal battens to reinforce the roof?

I'm thinking three battens of 1x1 douglas fir. One on centerline and the other two ~18" to 20" to either side of the centerline. Is that about right?

Re: Preparing for GT27 build - questions

Thanks Jacques. Since I already have the sheets of 1/4" Okoume ply on hand, that's what I'll probably stick with. I do see the longitudinal stringer on note 13 now. I had missed it, but that's exactly what I thought you might recommend. What are the dimensions for the thickness of each batten? 1"x1"...

Re: Preparing for GT27 build - questions

Sorry, I misread your earlier post. I thought you were talking about 2.5' (feet) wide spans between beams. Now I see you were talking about 2.5" (inch) wide beams and spans of less than one foot! Ugh, if 1/4" can't span one foot unsupported without cracking, that is a problem. I have a 20' sailboat ...

Re: GT27 Build (Wes K)

For the drain, I'm using the Wirquin Slim Extra Flat Low Profile Shower Trap. It's very low profile, has a built-in hepvo valve that prevents backflow/gases from making its way back up the drain, and seems easy to clean. It's 3.55" (90mm) diameter, though, so you pretty much have to go with a custom...

Re: Preparing for GT27 build - questions

Not a pain at all, Fallguy! I appreciate the input. Only that one yellow bulkhead is 1/4" ply. The roof beams are all three layers of 3/8" ply, so much thicker. I had to make that one from 1/4" as I don't have enough 3/8" on hand. I think strength will be fine, as I'm going to glue on a bunch of fra...

Re: GT27 Build (Wes K)

Interesting little project today: custom shower pan for the head. 32 x 33 overall. It drops 1/2" over 27" to funnel water into a small 6" wide trough. The trough drops another 1/4" over 16" from either side to funnel the water to the drain. A little sanding and some fiberglass to waterproof it is al...
