Installing roof planks

 Despite the rain I am making progress on the roof.. using PL Premium Max as the bonding adhesive. It has some great qualities, and most importantly works in the rain!! Especially since my shelter has now earned a couple small leaks!

So, I apply the Pl Premium Max in the groove and then on the topside of the tongue. I have been using a clamp to squeeze in the board. you can also just tap in light with a rubber mallet or push hard.. but the clamp is easy.

I then drill a hole with countersink for the stainless screws clamping the board in place while doing it. I will fill the hole with epoxy and wooden plug later. I know others have used nails, but this way I know I am not going to crack an oak roof beam.

I am working with 8ft and 3ft lengths offsetting the gap each end, so one row at the bow, and then on next row the seam is at the stern.

When I get a row in.. the PL has set enough that I just scrape the excess squeeze out off with a scraper. So far so good.. once I am done.. a light sand, hole plugs, and then sealed with epoxy and glass.

Starting the Roof - Pl Premium MAX adhesive?

 Started the roof today. Trying a new method to affix. I am using Pl Premium Max. Its a modified silane polymer (SMP) type glue and not a Polyurethane. I won't bore you with the science, Google it and theres lots of info.. but it means its super strong, and is 100% Solid.. which has been my biggest beef with regular PL Premium and it doesn't expand, bubble up and ooze all over. It also doesn't crack... It has twice the shear strength as regular PL Premium.. at about 1200psi douglas fir to douglas fir.

So why am I using it??. its easy to apply and clean up. I can use natural turps to clean tools, and wipe off unwanted areas.

I also don't have to wait for the right weather conditions and can apply even in the rain with a leaky roof tarp.

In fact, it so easy. I just use a putty knife to scrape off the glue squeezeout after 20 minutes when its semi soft for a clean finish.

So here's the info on the product. Once I'm done. I will coat the roof after a quick sand with epoxy and glass. But there has been some discussion about epoxy alternatives for gluebup. I don't know if its the right choice.. but it is working great for me. I am securing with stainless screws as well.

The hatch

 Began building a somewhat traditional hatch.  I plane to use a lockmiter bit for the joinery on the sides.

Hatch and bulkhead assembled.

 A little more work.. got the head bulkhead fitted, and the skylight frame. Used a lockmitre bit and despite having the setup tool it was tricky.. I don't have the best router table.. but got it together.. the best thing it fits and it appears true... now to finish the framing for the head.. and complete the rest of the hatch.
