Plywood coaming supports while skinning?

In the second video in the 'Skinning With Polyester' series brief reference is made to having support brackets on the sides of the lower plywood coaming ring to prevent breakage while skinning. Nothing more is said as the video progresses with a laminated one. Also no reference is made to these supports in the instruction manual. Are these really necessary? If so any suggestions on their shape or exact placement?

With the 11 oz fabric any thoughts about how to ensure it gets pulled tight enough when installing a plywood coaming (since the fabric reputedly doesn't shrink much)? BTW I'm OK if the answer is 'it shrinks enough to pull tight there'

Thanks

I have skinned two kayaks with the 11 oz fabric. After sewing the fabric tight ahead of and behind the cockpit I pull the fabric tight at the cockpit and staple it to the base ring. I pull it with one hand and staple with the other, working my way around the cockpit. I then sandwich the fabric between the base ring and the outer rings. 

   I have cracked the base ring by applying too much tension to the fabric. So now I install a permanent support on each side of the cockpit. If needed, temporary supports could be used while installing the fabric. Once the outer rings are in place the coaming is plenty strong. 

   You will get some shrinkage with a hot iron.

Ravenswood.

I got the plans this past February. I remember seeing a small frame piece on them that was labeled 'no longer needed' or 'not used' or something like that. Therefore this piece was never cut and now the paper scraps from the plans are long gone. Is that the piece you're referring to? Did I miss something?

Yes you did but it is not your fault. I started removing them and time has proved that to be a mistake.  I have been adding them back in as I go. Plywood coaming hold there shape well. Then I found that Baltic Birch plywood will loose it's springyness over time So were a good idea, they keep the coaming from sagging.  Shot me an email and I can send you a drawing file you can print of that part.

 

If you build a laminated coaming they are not needed.... at least the ones I have built.
