Has anyone played with using the two part epoxies that come in the the
syringes (1:1) to tack the boat parts in place? Package says 3-5
minutes to bond. can move in an hour, and sand/machine in 24 hours.

I could see some spots where they might come in handy, but was
wondering if anyone has tried them or not?

I have one, had it for some time now and its still good. This is the
double barrel syringe job with a single notched cap to prevent it being
put back wrong.
The only problem with this syringe is that the epoxy and hardener have
a different viscosity and this makes it difficult to push out equal
amounts of 'stuff'' after having used some of the contends. I have to
push at an angle to get anything near equal amounts released.
Not a problem for me as I use it for non precise work, the epoxy always
had gone off so far even if the mixing ratio must have been out
somewhat at times,

Yeah, I've used it. Don't trust it for anything structural. I used it
for a rudder yoke on a sailing canoe and on a little fold-up dolly.
Both failed fairly quickly. I think it would be OK for joints that
don't take _ANY_ stresses, or for sealing up edges of thru-decks etc,
but I wouldn't trust it for any stressed joint.

Good to know. I had planned on useing it to eliminate the stiches.
Rather, the boat is stiched right now. I was going to spot weld next
to the stitches so they could be removed, thus letting the fillets be
one continuous bead. Guess I'll go the regular route! Smile

thanks,
dave

What about using hot melt glue? If it's just for temporary holding of the
pieces together that should work fairly well. "Norm" from the New Yankee
Workshop used it when he did that one boat for his show.

It's really not that difficult to use epoxy for tabbing. IIRC I needed only
2 or 3 baches of 50 ml for cca 120 tabs. In case you proceed with filleting
before the epoxy is fully cured you may expect the tabs and fillets to bond
chemically. I have missed my "not fully cured" window and have lightly sand
the tabs prior to filleting with no consequences. Make sure that you wet out
the seams prior to filetting with unthickened epoxy to avoid "joint
starvation".
