2Thumbs Posted January 8, 2015 Posted January 8, 2015 Hi all.. I'm building Ravenswood and currently laminating the coaming. I used the pattern to make the jig and all the scrap ply went into my wood fired oven a couple of days ago. That leaves me with no dimension for the thickness of the lamination. So, can anyone help please ? I would guess that it is about an inch, but... Quote
Kudzu Posted January 8, 2015 Posted January 8, 2015 Actually you just want it thick enough to be strong enough. That is still ambiguous isn't it? But it really depends on the wood you're using. I used maple and I made mine about 3/4" thick. I never measured it honestly. I would try it and if it felt stiff enough I stopped. Quote
Hirilonde Posted January 9, 2015 Posted January 9, 2015 Using Maple I made the full width (height?) ring 1/2" thick and the lip a strong 1/4". I can't imagine anything I would do while using my kayak that could damage it. Quote
2Thumbs Posted January 9, 2015 Author Posted January 9, 2015 Thanks to you both for your help - I used Queensland Silver Ash and pulled it off the jig at 1/2" to see, and decided that it is likely strong enough. Maybe I can pick your brains a bit more.. Does the coaming sit on the centre stringer at the rear, and the two intermediate ones at the front ? Do I lash it on or is it retained by the cover when its stitched on ? Quote

Do I lash it on or is it retained by the cover when its stitched on ? Just stitch it in place. You might want to lash it it place long enough to get started, but the stitching on the skin is all that holds it in place. Quote
2Thumbs Posted January 10, 2015 Author Posted January 10, 2015 Thank you ! My ignorance is extensive. I know little about kayaks and I have never seen a SOF kayak in the flesh. I have built a number of boats, including a strip plank canoe but usually from plans, not patterns. Peter Quote
Bcone1381 Posted January 11, 2015 Posted January 11, 2015 When I portage my Ravenswood it gets carried upside down; the coaming rests on my shoulders. As I walk, the coaming will slightly flex with each step. It causes no concern, and this I think puts the most stress on the coaming of any activity I do. I made my laminated coaming out of oak to the same demensions as the plans called for. Quote
