Markus,

The two most prevalent 'theories' are based on Metal WIRE. Which 'side' you
use should really consider the MATERIAL of the wire. When first used, the
typical stuff was steel 'bailing wire', or some such. There were probably
any number of people who had RUST problems INSIDE the fillets, after the
boat was complete . . . hence the 'remove' school and the 'car battery
heating' technique. Someone came up with the brilliant idea to use COPPER
wire . . . no rust possible {maybe some green oxidation residue ??} so why
not leave it in ?? However, no one bothered to mention this to the 'battery
boys' so the technique is used on ALL metal wire.

Personally, 99 percent of the time I don't use wire. For the rare occasion I
have a problem making a portion of a seam 'fair' . . . I use 0.041 SS Safety
Wire. I have never had any problem just pulling it out 24-hours later. From
an engineering and 'chemical' standpoint, I'm with the most recent 'group'.
'They' recommend the use of 'Nylon Ties'.{In fact, I've gotten a few
packets - at a VERY steep discount - to have in my supplies inventory}. A
rather simple thermoplastic material {the cheap ones probably not even
Nylon}, that can be 'adjustable' {with some 'tinkering'}for tightening &
loosening. Available in a wide range of sizes & colors. No rust, no
corrosion, no 'meathooks', compatible with the epoxy matrix, and sandable.

Regards & Good Luck,

PS - The 'inside' or 'outside' question ?? If you are going to sheath with
glass/epoxy . . a moot point. Do WHATEVER you must to get a FAIR seam/curve.
Even if it is a mix of 'positions' due to tensions, etc. Easily filled in
when fairing & sanding the hull . . and invisible when sheathed . . even if
'clear coated'.

Hi,

I'm a newbie to boatbuilding and I want to build a dinghy for a start.
I have stiched together the first two sheets and now I want to put
fillet to glue them together. The thing I'm not sure about is if it is
important that the stitches don't get covered by the fillet.

Or should the stiches get fully covered with the fillet? What is best?
I have researched a lot but have not managed to get a clear indication.

Thanks a lot for your help,
Markus
