Hallman deck organizer

You have some neat homemade deck organizers on the Micro. I can't
remember where the pictures are. Would you mind pointing me to the
correct site and review how you built them?

> The problem seems to be that the selvedge stands proud.I routinely 'feather' this edge smooth by giving it a light pass with
a 4 1/2" angle grinder fitted with a backng pad and 36 grit sanding
disk. It takes some finesse and a steady hand, (because that grinder
does such quick work!), but with practice it is as easy as smoothing
butter.

The problem seems to be that the selvedge stands proud. Using a sharp
razor type knife I cut off the edges before using the tape. The tape is
a little unhandy after the cut but if rolled up and unrolled carefully
it will laminate without the bump.And the fairing is much less of a problem.

next time cut the edges with a utility knife ,new blade, before epoxy. it will come out like the good side on both sides.
iused a 2" grinder disc 36 grit, 3m from auto parts store in cordless drill. took it off fast. then faired the mess it made.

A Payson Pirogue would function just fine with no sanding or filling
whats-so-ever, if you can accept the looks.
There are a thousand possible techniques to smooth and fill, my
general technique is to:
1) Rough pass grind with a coarse angle grinder, and then flatten with
coarse sandpaper on a belt sander.
2) Then, using a flexible drywall taping knife spread on a very thin
layer of epoxy including some glass microspheres to assist easy
sanding. For vertical surfaces, include some thickening agent
colloidal silica powder. Let cure until hard.
4) Gently sand smooth, using fine paper on belt sander and/or random orbital.
5) Primer paint. After the prime paint, imperfections can be better
seen, and sometimes you need to back up and repeat some of the first
steps.
6) Finish fine sanding using a random orbital sander. Inevitably at
this point you find a few surface imperfections and pin holes that
need filling, and the quick-dry auto body "glazing and spot putty" is
really handy.

The finished hull should be as smooth as possible.
I do this by knocking the edges of the tape down with a Sandvik carbide blade shaper after the epoxy has kicked and while it is still "green". Then I fair the tape using a wide putty knife and epoxy which has been thickened with micro balloons. The technique is similiar to mudding drywall tape and, for me, involves at least 3 coats with sanding in between.
One of the frustrations of boat building is that the assembled hull represents no more than 40% of the time needed to finish the boat! However, the first thing people notice is the finish, and shortcuts taken during the finishing process can spoil the whole efffect. And at some point during the sand and fill (and sand some more) we all reach the 'Hell with it; that's good enough' point.

Subject: [bolger] Grind tape edges versus fair edges with thickened epoxy?
I am building a Payson pirogue, using the tack and tape method. I'm using 2
inch wide fiberglass tape and epoxy to tape the inside and outside seams.
The edges of the tape stand proud of the plywood panel. Is this best
smoothed by grinding down the edges of the fiberglass tape, or is it better
to apply epoxy thickened with microballoons to fair the edges?

After the epoxy in your glass tape has cured you should
feather the edges down as smooth as possible. Then fair
the feathered edge with a top coat of epoxy thickened with
microballoons (or talc) and fumed silica.
-------------------------
The next time you tape your joints you might try covering
the tape with a wider strip of tight-weave 100% polyester
fabric before the epoxy starts stiffening up in your
joints. Use your gloved hands or a plastic squeegee to
carefully smooth out the glass and epoxy beneath the
polyester cloth. The polyester on top of the glass will
press and hold the edge of the glass tape down against the
plywood panel while the epoxy cures.
After the epoxy has cured, simply "peel off" the polyester
fabric and throw it away. You'll be left with a nice,
uniformly textured surface on your glass taped joints which
effectively reduces or completely eliminates the sanding
and feathering of the glass tape edges.

I would fill and fair the tape edge but also knock off any large lumps first.
