A bit more scarfing on the final keel layer.  Should have this glued on Friday if Iselle cooperates.

Well this is boring so here is something a bit more tooth worthy:

Three layers were laminated yesterday and the work went very well with the team.  Opted for some available 207 Special Clear hardener that was available in town instead of 206 to help slow things down. Attention at the stem and 1-3 stations really paid off and the laminates fit real well together. We set screws along the length in various locations to locate and clamp a bit.  Those will come out in a day or two and get filled with epoxy.  In about a week we'll add 3-4 more laminates that should build up to the level where cross members attach.  The cross members perhaps can be installed once the molds are setup and the hull line is established, properly positioning them prior to skin being built.

In the mean time will remove and fill screw holes with epoxy, build up laminate layer F and turn some 10' planks into 20' stringers for the mold.

Keel lamination to start:

The buildup of the keel is starting tomorrow.  I recalled I missed some trim on the C laminate so I quickly glued that up today and it should be good to go tomorrow if we get that many layers stacked.

Here is the transom, 8 and 6 stations being laid out.  All moulds were built referenced to a horizontal baseline.  The stem should sit 50mm above the base frame and everything moving up from there.  Storing these for now while the keelson laminating gets ready.

Discovered the loft value errors.  I was comparing them to the templates...duh.

Just added a water fountain in the shop for the hot weather(in pic below). Someone was throwing it out.  It needed the valve rebuilt but the refrigerant cycle works and there are no leaks.  A little paint and scribing and we get chilled water....yeah!!!

Started building some moulds.  I assumed I would lay it out on the floor but there is so much chicken sh_t around  from the wandering birds I am working off of a panel.  Paper traces are transfered to boards, cut, fitted, assembled and soon to be final shaped.  Only need to finish up 7 and 8 and the transom.  Everything is sized for 1/4" skin and 5/8" battens.   In another week or so we will get a crew together to glue up the laminates on the keelson.  I think the keel mould can get taken down by end of July and then the station moulds setup.   Those aft stations 6, 7, 8, T  really get some tight turns.  My battens for tracing lines (or whatever you call it) started breaking.  I eventually used a piece of balsa and tiny nails set at each loft point with the balsa bent around them.  That would have been nice to try earlier on.  An offset line at 22mm (batten and skin) was then drawn parallel to each true loft line giving the mould outer line.

Much bigger now...

6/4/14:  More of the same.  Building up laminates A, B, C, D.  Then a smaller set of E thru G to follow.

The curvature in stations 3-2-1-stem proved a bit much for 10mm laminates C, D and E.  I am putting together a steam box to help bend the whole set before gluing.  Not sure how long this will delay keel work but stations could be worked on in the mean time.  Sort of a hodgpodge of picture here showing more laminate buildup, planing, fitting and prep for bending.

Standby, I am getting close to starting up the work again.  For now here are some really great videos:

More of the same.  Lots of scarf and glue.  The glue bench could use an upgrade but so far everything is straight.  Maybe two weeks before a real layup is possible.  It would be nice to do A-E sections.  I revised the laminate sheet and I am considering steaming the length of the laminates from the stem to section 3 then drying them in the form jig.   The 10 mm sections take the curve but one cracked at section 2.  With six or seven layers I dont want to blow it up.

Had some difficulty with resawing and controlling board shape.  It is getting better but going real slow. There is a warp in the plank I started with that I am fighting that has forced some an extra step of building up planks for the lamination layers.  Each piece is getting a coat of epoxy following the West System folks method.   Some wood bees have really been storming the jig as well.  Three of them just today.  The ants are in the process of carrying away their bodies.

The scarf tool, resaw jig, and epoxy coating work space are setup so as soon as the design gets adjusted for these errors in sizing it should pick up speed.  Well we'll see.
