Join lamination

[link]

I have a couple of questions about join lamination - that is before the main hull lamination

Just want to confirm a couple of details:

* Bow (over the stem cap) should be 2x600 or equivalent?

* What's the preferred order - stem cap first followed by bottom and chine joins or the other way around?

* Lamination of other areas where plywood panels join and there are butt blocks on the inside - what weight cloth? Can it be 200gsqm or does it need to be 600+? Is this optional? Recommended? I don't see any spec in the plans for that.

* Reinforcements for other high-stress areas such as skeg, rudder mount and daggerboards - 600g/sqm?
* Stern corners - also 600g/sqm?

First off You should wait for an experienced builder to chime in.
I’d email Janusz and Don they are valid questions and there is a builders update coming out. My thoughts for what they are worth below.

Bow (over the stem cap) should be 2x600 or equivalent?

——- as you put below the transom is 2x600 and it looks like all the other high impact/stress areas are the same. So I assume 2x600 on stem.

* What's the preferred order - stem cap first followed by bottom and chine joins or the other way around?
——- I’m going to laminate my vertical and horizontal joints to some extent. 6oz - which is roughly 200g, on every joint, with the horizontal runs going around the corner. Then lay the 2x10oz (2x340g) 600 over the top of that so on my transom joints there will be 800g and on my high impact areas. 200s on one day, 600 the next day is the plan. I know people can do more cloth at a time but I’d like to round/smooth/tidy my corners with the 200 first. Keep in mind I will then put 1220gm over every thing below the deck.
There is also stainless steel up the front so where my pulpit attaches further down the boat I’ll be going 800+. Running that mass of stainless into the dock is going to transfer the force back down the deck, You’ll note on trekka there are few areas not on the plans that have more glass, last video on the trekka tour post transat for instance you can see glass laid up towards frame D internal, Don had said some thing about more glass around keel and maybe crash box internal.

* Lamination of other areas where plywood panels join and there are butt blocks on the inside - what weight cloth? Can it be 200gsqm or does it need to be 600+? Is this optional? Recommended? I don't see any spec in the plans for that.

I can’t see it on the plans either and answer on butt blocks I was going to go 200 only. As with my ply I’ll have 1220gm over everything on top of what I put on the high stress areas.

* Reinforcements for other high-stress areas such as skeg, rudder mount and daggerboards - 600g/sqm?

Or more


* Stern corners - also 600g/sqm?

On Ark3 in a note bottom right, 600g

Is there a build manual that comes with the plans without having to look at every blog and youtube video?

Are all the screws left in. In general stitch and glue methods removes screws and fill the holes?

This is not clear in the plan details, although I see many builders driving in screws in all the bulkheads.

Hi,
I dont think that you will see a builders manual with your plans ......
Screws are to be left in as per Janusz. If your just building it and you dont plan on Class races then I guess it dosen't matter.
Cheers,
Dan
