How to hang side panels
« on: March 15, 2008, 04:17:50 AM »
Question -

I have Jumbo 24 kit and am about to hang the side panels. Each side has a 3 sheet side panel glassed and ready to go and a 4th panel glassed as well. Do I start at the transom and hang the 3 sheet monster first or do I start at the bow with the single sheet. Seems like it might be easier to place the large section first and finish off with smaller bow panel.

Answers -

K. Dodson:   I did it both ways.  On the port side I temporarily hung the long side starting at the transom using S/R screws.  I then took the last sheet and temporarily screwed the scarf joint and sides on and rough marked it.  I marked it about 2" proud of the true cut line.  I made witness marks on the scarf joint to get it back together.  I then removed to whole things and did the scarf joint on the ground.  After the scarf set up for several days (don't rush the cure) I dry fit it again starting at the transom.  After I was happy with it I released the bow to take the pressure off and with some help to hold things removed the screws and added the thin and thickened epoxy and glued it all up.  It worked well but I was glad I had the extra 2" as things didn't go back together exactly the same and I needed it.  I also had help getting the 24' side back in position.  That scarf joint can not be seen unless looking real hard.
 
On the Starboard side I got a little cocky and still starting from the back I attached the 3 sheets which were scarfed together.  I dry fit then epoxied in place.  I then epoxied the scarf joint after dry fitting the bow piece.  It was a little more difficult but faster doing it that way as I didn't have a helper handy.  My scarf joint wasn't as nice and slipped a little proud.  I didn't notice it until it was primed and painted.  You really do not notice it unless you look in your side rear view mirror when pulling it down the road  At that angle you see a little line where the joint is.  No one else has mentioned it but I see it when towing it.
 
But to answer the question you asked, I started at the transom and worked forward.


B. Southwick:  I started at the bow and worked back. This way your 8' panels are already scarfed and glued and will more easily bend over the hull curvature. I did it this way and it seemed to go fairly well.  Since I did one side alone I made little "hangers" to rest the long sheet on so I could more easily slip it up into place by myself. Once the forward panels were attached I then scarfed the last sheet to the forward sheets. That was actually quite easy, but it would be difficult, I think, to have tried to scarf the last sheet on anywhere over that bow curvature. Also starting from the front and working back allows you to hang any excess back past the transom and cut it off easily.


"dinghyman":  Here's a step by step guide. I thought I posted this already but it
was a no show.

Front to back seemed likte the easiest approach to me. Here are a series of web pages that show how we did ours.

You could of course just go to the first page and advance from there.

I'm getting ready to hang my side panels and was very confused on how to land the front piece against the bow stem.  Many thanks to Walknbob for posting the last picture on page https://fishyfish.com/walknbob/ourboat/day_030.htm

This cleared up the confusion I had on how the side panel lands just under the forward end of the chine shelf.  Turns out it doesn't, the stem needs to be shimmed and/or filled with thickened epoxy!

 Yep, my side panel to bowstem joint required a shim exactly like Bob's did. I used a bit of scrap Fir from the bowstem itself then filled the rest with glass fiber filled epoxy.

I was able hang both rear side panels as well as the starboard front panel over the weekend.  Here's how I did it:

Neal's kit comes with 7 3/8" 4x8 sheets.  Two of these have scarfs on one edge, the other 5 have scarfs on both edges.  One of the panels with both edges scarfed gets cut in half.

I ripped 3 of the sheets with scarfing on both edges to 36" width.  The other 4 panels were ripped to 40", two of these have a scarf on one edge.  The panels with the scarf on one edge go to the bow.

One of the 36" width panels was cut in half, these two pieces were glued up to the other 36" width pieces to become the rear panels.  These were glued up to the boat, the top edge was used to align the chine edge.

After gluing up the 40" panels for the forward sides, I placed the starboard side panel on the boat, tacking it along the scarf and then bending it forward to the bow stem.  After marking and cutting, I glued it up to the boat, scarfing the rear edge of the forward panel to the front edge of the rear panel on the boat.  Where the scarf is made on the boat, the lower edge of the forward panel should be flush with the lower edge of the rear panel.   Next step is to plane down the sides flush with the chines.

Here's how it looks:
