Sunday Session...
My apprentice and I learnt the finer ways of rounding edges using files and sandpaper. We rounded all the frame arms this way as I don't have a router. We also cut all the centreboard lammels and epoxied. Used about 50-60 strokes of epoxy. We used a nothed spreader to spread thickened epoxy and then sash clamped. Not a bad week.

Stem doublers
Also glued on Stem doublers today. I cut out where the stringers will go. I kind of guestimated the angles from the plans and transfered to doublers. To stop items moving as the clamps are done up I have been pre drilling holes and nailing. This seems to work and stops the items sliding around. Also found these cool nothed spreaders at Mitre 10 for spreading epoxy.

Finishing Frames
Finished epoxing and nailing on seat back (coaming) and seat supports onto frames. I decided to try some silicon bronze nails to see if it would speed up construction. Was a little faster. Still had to pre drill 20X20mm kahikatea to stop it splitting. Turned out to be a two person exercise and a bit messy. Any way got it all done tonight.
Will pre-coat frames with two coats of epoxy sometime soon as per West System guidelines.

Frames 2 and 4 continued
Frames 2 and 4
Frame 2 and 4 ready to assemble. First put down wax paper over MDF template where epoxy is likely to dribble. Then clamped sidearms to template. Then attatched bottom panel and top panels.
Presently days are spent making final adjustments to side arms and panels. Also marking, cutting out, and pre drilling floor supports. Then after dinner epoxing it all together (then updating blog). In the morning will tidy up and notch for stringers Then work on next frames.

First two frames complete
Frames 1 and 3 complete for now. What a messy job epoxing is. Will need heaps of rags I reckon. Pretty pleased. Had to do a quick mock up with the stem. Gives an idea of the dimensions.
Hopefully will have all the next frames made this week as long as I am not called to work. Will glue up frames 2 and 4 tonight.
Little helper
Epoxing frame 2 and 3
These frames happened to be the ones I decided to tackle first. The side arms are separate from the base and need to be screwed and glued to each other This was done by placing pieces over template for alignment and clamped.
To prepare a joint for epoxing both pieces of wood are pre coated in raw epoxy to wet out the area and left for a few minutes to soak into the wood. Then glue powder is added to the remaining epoxy and added to one side only. It is then placed in position and clamped or screwed together. Not so hard that all the glue is forced out of the joint. This method avoids dry joints.
