Start up trials








The build starts













Impossible to get dowel of this size locally so it’s a DIY job on the lathe!

- Shortening an elm cockpit,
Split the glue joint
Then Soaked the ends - Soaked ends ready to go in the steam box
- Loose ends jammed in the steam box
- ribs, soaked and ready for steaming, note test pieces underneath
- ribs, soaked and ready for steaming
- Rib steaming in progress. the first 4 ribs all cracked even after 3 goes!
- repairing cracks in ribs, gorrilla glue and duct tape
- Bow for marking curves made of masking tape and a thin lath
- Ready for the keel
- Stem and stern clamped in place to check fit and mark for lacing holes
- Stem
- Stern
- Note rib is made of 2 laminates
- The original cracked and had to be replaced
- Lining up the stringers, quite a struggle to bend them into place
- Winding sinew on the lathe
- more bending of the stringers, the clamp setup made it easy to adjust
- Did the lashing in 2 stages, bow first and then the stern section
- Checking the ribs don’t poke out beyond the stringers
- Glueing the secondary stringers
- Glueing blocks at the stern
- Footrest made from a cedar block; the face next to the gunwhale is cut at a 20 degree angle
- Footrests in position set by sitting in the boat
- Hefty stainless screws to fix the footrests
- Screws set at different angles through into the footrest
- Bits and pieces used for a back rest
- The D rings are fixed to the gunwhales. The tape either side of the back rest will lock in.
- Elm bends easily but the grain was so distorted that the lip was made up of 3 – 4 mm strips
- Elm coaming glued and screwed
- 100 watt soldering iron with adapted blade
- Sewing the stern
- Hull after coating with Danish oil
- Hull after coating with Danish oil
Now for the “loop and gloop” stage.
The skin is Ballistic Nylon, high tenacity, greige fabric, 850 den, 310g/sqm, white from Extremtextil, Dresden and the gloop is Lechler (Como, Italy) LS140 (29140) Isolak High and Hardener (29340).
The materials were bought in a rush before Brexit so I have no idea how they compare to the recommended Corey products used by Brian. So I asked advice from Brian also from Franz (Bavaria) who did use similar products. What follows are some pictures of tests and the final result.
- Bow and Stern sewn, ready for cutting surplus material
- Stern laced, lots of wrinkles and holes
- Lacing holes getting larger as I increase the tension
- Test piece from offcut sewn onto a tray with moderate tension
- Test piece wetted. It sagged in the middle from 15 mm when dry to 20 mm wet.
Note the remains of the crease mark from when the material was folded. - Ironed but still damp
- Dry. Not quite drum tight but a lot better than at the start. Still a bit of the crease mark showing.
- Aft deck before shrinking
- Aft deck before shrinking and after removal of the lacing. After wetting and ironing dry all of the wrinkles and sagging disappeared.
- 2 part urethane mixing setup. Note two cups premeasured and marked for 90 and 180 ml.
- Hull after two coats of urethane. I did four eventually. I think the temperature was far too low, maybe 10 degrees C or less, it was minus 2 or 3 outside! Perhaps this is why I have a matt finish rather than gloss. But it has dried hard.
- cockpit – finished boat
- cockpit, deck lines and backrest – finished boat
- bow and foot rests – finished boat
- Stern and back rest – finished boat
The Launch
A mild day after a long spell of cold weather so the launch is “go”. The F1 has had a few days for the paint to cure but it still reeks. The boat weighs 15 kilos. ready to go, except there are no bouyancy bags. It is easy to lift one handed though I am surprised how far forward I have to hold on the coaming to get the balance. I’m lucky, I can put in in front of the house, down the garden and over the railway.

First Impressions:
A very comfy sit, the matting, back rest and foot rests are all spot on. The full length keel makes it a bit wobbly to start. As there was noone else on the water and with no bouyancy bags I didn’t test the limits but the secondary stability with the hard chines seems good. It paddles easily with no hint of the side deck getting in the way. Directional stability is good, no problem drifting in a staight line while taking photos. On return after two hours on the water the boat was dry inside apart from a few drops carried in from my feet.
Verdict – excellent – can’t wait to try in more testing conditions!

Well done Paul, looks like the Elm has bent nicely, was it green or had it been dried? It’ll be good to see your progress. You’re in a good place to launch and get some superb trips. Best wishes,
Chris.

That looks like good progress, by the way, it appears that you’ve had to saw the deck beam free from the jig. I prevented this by putting a plastic sheet, with holes for the pegs (i just cut ‘x’s in the plastic), over the board to stop glue adhering to it. It was just a sheet of thin stuff, large plastic bag really, a bin bag would do.
How has the cockpit worked out? I have some oak left over for both the coaming and added rim that you could have if you need it.

Good effort, Well done paul. that looks beautiful.
I’m interested in making a greenland paddle myself and a skin on frame kayak myself and would love some advice from your own experiences. Here’s my email address incase you want to get in touch and help me out

Hi Jason. Thanks. I made my paddles just by copying others I had seen, and before I had seen CFK’s excellent videos. Unless you have ready access to Cedar I would recommend starting with a bit of cheap spruce or pine from your local builder merchants. That way you can make mistakes and try out the dimensions to suit you. But watch the videos they will short circuit a lot of the potential errors.
Cheers
Paul
