Re: [bolger] Methods for placing & spreading putty in fillets?
sounds like you may have a little bit too much thickner and not enuf epoxy

Don't put so much thin goodge on at first and then, let it gel before trying
to add the thick filleting material. Saves a lt of frustration. I get in a
hurry too.

My first thought was that your mixture is way , way too dry but then you

suggest trying it very runny so that you may have to go back and reshape for
sags and see how you do.
Normally I just scoop in a pile and spread it down the seam with whatever I
am shaping the curve with. It just flows out in front of the shaping tool.
It is thin enough that it doesn't have the tensile strength to pull itself
along. Any tendency to ball up would indicate to me that it was too dry.
I have used silica, wood flour, chopped strand and micro balloons for
fillers.

1. let prime set up just a little
2. use plastic spoon, works fine. end for sharp corners, side for
more
open corners
3. mix epoxy before thickener, unless you want your boat to suffer
the
same fate as my friend's model airplane wing where he mixed in the
filler first. CRACK! pause! THUD!
4. use only finest fillers (I'm talking texture here, not snob
appeal)
I've had good luck with wood flour from GlenL, and also, if I recall
correctly, from Raka, but there are probably plenty of other good
things to use
5. Mix in a little silica (i.e. cabosil), maybe 10% or 20% of your
filler, more is harder to sand but ok
5 and a half. consistency somewhere between mayonnaise and peanut
butter (the petrochemical kind, like Skippy, not the natural stuff)
6. Put on the tape as soon as the filler stiffens up just a little,
or
maybe sooner. THen you don't have to sand, you can just push the tape
with a glove or brush until it fits. I have a project boat that
someone else started, epoxy and tape over bondo, and they have voids
because they didn't have smooth filler in the corners. (Actually, the
voids belong to me now but I hate to admit it.) Sanding filler is a
pain.

Hi Garth,
I have had the best results using a piece of tubing. I bend the
tubing so it has enough curve that the end is almost parallel to the
corner. If it is pulling up, or curling and coming out, lessen your
angle and press it into the corner with more pressure.
I hope this helps,
Stan Micro Tugger, Snow Goose.

Hi
Check the shop tips at the Chesapeake Light Craft site -- they explain it
very well. However, sounds to me like your putty is too hard and the
pre-wetting is too wet -- maybe let it sit until tacky, then put on putty.
Personally I have the putty only stiff enough to stay in place without
drooling, and I only pre-coat very lightly, if at all. Putting tape on
right away will help combat drooling by sloppy putty, too.

I have used plastic spoons and flexible spreaders cut from plastic ice cream
tub lids. Still, I can have a bad day! The most foolproof way is to set
the tape in the wet fillet, then smooth the whole combnation with (gloved)
fingers.

Let the wetting out coat setup or start to set up. With Sys Three at least,
you can still make a chemical bond for a couple of days after the first coat
sets up. Reuel Parker uses a zip lock plastic bag with a corner cut off for
a disposable cake decorating thing. I haven't tried this yet. You can clean
up and shape, partially setup fillets with a rag, soaked with denatured
alcohol as the alcohol evaporates very quickly. Clyde Wisner PS: besure to
clean epoxy off the door knobs, telephone and water faucet handels and life
with signif. other becomes easier.
