1. Plans arrive for Joansa, a John Welsford design (NZ)
Date: 30th June 06 |
2. Building jig - lovely straight 2nd hand oregon. |
3. Jig commenced 1st July 06 with an emphasis on square & level. |
4. Jig finished on 4th July 06
Only recycled timber used. The whole thing unscrews for storage. |
|

|
5. Lofting frames to full size. I copied the plan & cut it into small sections for ease of use. |
6. Tracing the frame parts for later transfer to plywood. |
7. Scarfing the bottom plank (12th July) to an angle of 1 in 8. Offsets being 8 x 6 =48mm |
8. Starting to plane the scarf. |
|

|
|
9. Scarf planing finished... |
10... and epoxied together (20th July) |
11. Cutting bottom plank with a jig saw. |
12. Frame tracings were used with Saral "transfer paper " to copy the drawings to the ply. The little roller wheel was good for tracing curves |
|

|
13. Tracing multiples. |
14. Cutting frames using a rough "Vee" support. You really feed the ply into the jig saw. |
15/16. Frames and bottom plank get a coat of TPRDA epoxy.
(I later just coated the whole sheet of ply which is much quicker) |

|
17. Frame components undergo assembly. Epoxy doesn't stick to black garden plastic |
18. Test fit of the bottom plank. I "waisted" the hull supports which proved very useful during planking. |
19. I also slipped the hull position back slightly so that the jig didn't interfere with the frame positions (didn't really matter anyway). |
20. Some of the incomplete frames propped in place to give me a rough idea of appearance. |
|

|
21. Frame 2 stiffeners go in place.
I am using Hoop Pine which is in 18mm thick boards. This is ripped and thicknessed to 18 x 12 mm |
22. Frame 3 stiffeners (under rowing seat)
|
23. I thought I had enough clamps - no way. Now I have well over 40 and it's still not enough. |
24. Doublers epoxied to the stem.
