I picked up another 25 yds of glass cloth last week, so the Glacier is advancing again.
The last panel I did was just two straight, flat pieces of cloth. Now that I'm working on the corner, I figured I'd post up the sequence of shaping the cloth for anyone who's not sure how to do it. It's easy and is by no means the only way to skin the cat, this is just the way that works for me.
Never fear, I won't go into this much detail for every panel since the layup is the same for all of them.
The first step is to cut out a 'bite' of the trailer to work on:
Now drag it downstairs to the table (as much as you can 'drag' something that weighs only 5 or 10 lbs):
And nope, the rowboat hasn't moved since the last post....and there are prawns to be had.....
A bit of 'fairing-compound-in-a-can' to fill before final sanding:
The next pics are milky this was where I wrapped my phone in Saran Wrap just in case there was a good time during the layup to take a pic (there never is). The table with the hanger up for the cloth:
It's covered with paper because crap gets into the weave otherwise, especially if you're working outside.
Cloth laid out for length:
Note the cheap disposable scissors - don't need pricy shears for 6 oz cloth. Razor knives (Olfa, etc) also work great when run along a straightedge....just not when you table is covered in plastic sheeting to ward off epoxy drips ! :
Get that cover back on the cloth !
Gathering the excess cloth in the corner and checking that the bottom and far edges are squared to the foam. Oh, and giving up on the Saran Wrap, too.
Laying out the dart to cut out of the corner. Grab the trusty Sharpie and run a line down the corner. Then fold the corner the other way to get the other line (on the bottom):
And wind up with the rough triangle you need to cut out.
I've left myself a bit of an overlap to ensure that the corner will have two thicknesses of cloth over it. The overlap decreases as you get to the end of the cut to keep the cloth from 'piling up' in the corner.
Taped into place. After smoothing the cloth towards the other end and making sure the weave is square, repeat the cut on the opposite corner.
The leftovers will become tape. Cutting it into short strips will give me a way to use any leftover resin to add more glass to the corner.
And into a bag to keep it clean.
No mid-layup shots, but here's the result. Notice that the Sharpie marks show through.
My faithful assistants gave up on me:
But that's ok, they went to the park later.
I have been using this rudder build as a place to use up leftover resin - I hate when it goes to waste just because I didn't think of it before mixing the batch.
By the time I'm doing the final outside layer of glass, I'll be laminating the tiller or the dagger board for that project.
