Peter from South Australia building F2

Well I have been putting this of for awhile, not the blogging but the building of a double kayak. My wife finally won out. So here I am building my 5th skin on frame Kayak. and I must say it fills my shed, barely enough room to get around either end. It keeps me fit all the walking around the kayak. I started by building the coaming, my main load of timber hand’t arrived yet so using up what I have laying around. I am trying to use PAULOWNIA for the main frame and bamboo for the ribs. so far the combination has worked well on the 2 F1’s

With the coamings I use 4mm x 37mm thin laminations 6 of them and laminate them together with Epoxy resin bit fiddly but it seems to work. I steam bend the laminations first let them set then glue them. next image you can see them laminated and curing.

Laminations clamped together glued with epoxy resin, steel band helps to stop breakout of timber
Finished Coaming ready for cleaning up with belt sander and then cutting the lip with a dome shaped router bit

Bamboo ribs laid out ready for measuring

.Ribs cut to length and ready for soaking, I use bamboo so I find that soaking overnight makes them easier to bend


Using rib measuring stick to determine rib length

Ribs numbered and cut to length ready to soak overnight, I do this as I use bamboo and found it steams much better once soaked.
Ribs in position and not looking to bad at all, they say practice makes perfect being my 5th I should have picked up a bit of experience.
Keel in position and sitting rather well only had to tweak a few ribs
Looking down the the F2 with pull cords fitted for float bags / cant seem to rotate image sorry.
Showing a few of the pieces that I have added to the kayak and how things are mounted
I use minicell foam to create our sites ( called close cell foam in australia) by using the foam it helps support as you drop your backside onto the rear deck beam to get in. I don’t use hard wood so it helps with support of the beam
if your wondering what it is? It’s a 5 amp Reed Switch being encased in epoxy this I activate with a magnet also encased in epoxy to work the pump.
This image shows the deck beams between the front and rear cockpit. I kept a more rounder shape to allow for easier placement of maps and compass and anything else.
start of skinning process using 820 Primo, rubbish bin holding tools .
Cutting excess fabric using a gas soldering iron with a shape bit that has a cutting edge a bit slow but works well.
Sewing the fabric, using the 820 primo and temperature being in the mid 20c, needed to keep the fabric thoroughly wet this was done with the help of my wife.
All stiched and out in the sun drying had to do very little shrinking with the iron keeping it wet made a tremendous difference
Image showing deck lines in place and other fittings.
For the deck lines I decided to try the more conventional method of holding line on deck. With the number of deck beams on the F2 it worked really well. S/S countersunk head bolts and a domed nut underneath with washer.
Showing the domed nut underneath holding deck line in place. Also a small wedge that stops the leaver falling out of position in a capsize event. in the F1 when I am rolling
F2 on my old Landrover ready for its christening at our local reservoir
Paddling on the reservoir as soon as I can get a pic or video of us paddling it Ill put it up have been out about for times so far only on flat water but what a fantastic double.with all the extra bits in it and hanging on it including float bags it comes in at 25.5kg. very impressed with that. Makes it very manageable as your getting Older. My wife loves it just took a bit of time to get our act together so to speak. Fantastic Kayak Brain.

Hi I am Peter a energetic young 70 year old that has come back to kayaking after an absence of about 45 years. I enjoy working with my hands and always making or creating something. Building skin on frame kayaks fills both of my needs. Have worked in the building industry most of my life, about ten years ago turned to photography for my semi-retirement job. I want to be able to work as long as possible and kayaking is keeping me fit. I already own a west greenland kayak in which I am learning to roll.
