Funky widgets

I used my epoxy-free week (dang, stuff takes a long time to ship here!) to figure some stuff out, and cut a bunch of G10 parts to be ready to glue up.


I'll let these two pics speak for themselves. If you don't know what the parts are, you'll probably be offended, or something!



Also spent some time thinking about the jib tracks. The little hole in the cabin side is for the jib clew height line which will go the car and up to the clew, so I want the track to be sorta square to that, so that as the car is eased out along the track the clew at least won't be pulled downward -when you ease something, you generally don't want to decrease twist. This also slants the outward edge a bit further forward than usual, so that easing the car will also decrease the distance to the tack, which is what you usually do when you ease from close hauled to reaching.

The little stick jammed into the chainplates is to indicate where the lower stay will be, so I can see how far back and in I can get the jib clew.

The green rope is part of a clamping apparatus to glue in the little cleat boxes I made a  long time ago, into the bulkhead. I put some pics on the Picasa site and not here- they show some stuff that would ruin the mystery of the funky parts and I can't have that.

Edit to add some progress pics of these parts:
Poor man's lathe:
chuck the bolt (shaved to 1/2"ΓΈ) in a drill press, and run an angle grinder against it while it spins. The cup was just cleaned up by hand sanding.


The cone gets wrapped in some cloth to create a stable mounting platform. I bagged it since it's tough sometimes to get the cloth to conform to the tight corners.


After bagging. I'll trim it to about 1" past the cone, then G-Flex it to the cabin.


Trying a bladder to make a inside-of-mast shaped sleeve to incorporate into the mast base cup support.
I'm dubious this is going to work on the first try, but I'll see in the morning. I have ideas for a simpler method if this turns out pear shaped (literally?).


And here's the little cleat recess boxes. Shades of the transom of a Santa Cruz 27?



Ah heck, I'll edit this again to add another progress pic of some of the parts mentioned above:
This is the internal sleeve for the mast which came out alright, the "bladder" -a piece of 1.5" latex tubing from McMaster with some closet rod pieces shoved in the end, and the assembly of the mast cup. The mast cup will be bonded into the sleeve, which will be bonded into the base of the mast. I'm not ready to do any mast work yet, but I want to get these parts built at the same time as my mast step, so I know they will all work well together, later.

Also in the pic is my jib track backing plate- a piece of scrap 1/4" ply with two layers of biax bonded to one side. I'll cut it into two inch strips and glue it to the underside of the deck, and the glass will be a hard surface to prevent the track nuts and washers from sinking in.

Also got the compression post top fasteners bonded into the cabin top, and some parts of the compression post assembly glued together. Lot's of little things to do before painting the inside, it seems. Besides, this is much more fun than sanding the deck!
