Re: Panga 20 Build
Yes, I meant fiberglass splice. The plans I have don't show an offset.

Re: Panga 20 Build
Don't know if the nesting drawings we're ever updated. It still shows the stringers that would have to be spliced. I think I misunderstood this post and thought they were supposed to be spliced. Oh well, they are cut and spliced already.

Re: Panga 20 Build
It's just the picture distorting. There is an angle. I don't know what it is. The motor wells provided the angle that was specified by the plans.fallguy1000 wrote: ↑Fri Jan 11, 2019 10:21 pmWhat is the transom angle at the DWL? It looks totally square to me. What am i missing?FluidDynamic wrote: ↑Wed Jan 09, 2019 9:41 pm The epoxy cured. No problem.
I placed the transom a little earlier. I ran out of 2x4's so I had to temporarily brace the transom. I'll build something more substantial tomorrow. On my plywood cuts, does it matter if it's off a little. The transoms edges overlapped each other a little. I'm assuming this will be taken care of with either sanding or epoxy putty? I guess the stringers are next. I've been checking the cross dimensions and the dimensions between each frame. Everything is lining up. The stringers should go in no problem. The stringers will be cut with notches. I'll have to cut notches in the frames.

Re: Panga 20 Build
I epoxy glued the stringers this morning, cut the notches on the frames, and braced the transom. I should be able to place the stringers on the frames tomorrow.

Re: Panga 20 Build
I have a question about using epoxy on fiberglass. When I built a paddleboard, I used cloth and filled the weave with multiple coats. Am I supposed to fill the weave with multiple coats of epoxy with the 12 oz biaxial cloth? If I only have to place one coat of epoxy on the hull, won't the sander eat some of the fiberglass cloth away. I'm a little confused on the steps to get to where I have a fair surface.

Re: Panga 20 Build
Have a good look at the FS17LS build by shine on builders power boats. It goes through the steps. There may also be a tutorial in the How tos.
In brief.
Lay glass and when it kicks but before full cure you can fill the weave with a loose mix of epoxy, cabosil and or a microballon filler.
Then after it sets grind down obvious highs with a power sande
Then fill lows with fairing mix. WEST 407, 411 or similar
Longboard
Then fill lows with fairing mix. WEST 407, 411 or similar

I missed most of the above in my dinghy, so it looks a bit rustic.

Re: Panga 20 Build
The sanding generally touches off the knitting or the stitching in biax. That stitch is a telltale and not part of the main fiberglass. There are basically two methods.FluidDynamic wrote: ↑Sat Jan 12, 2019 9:38 pm I have a question about using epoxy on fiberglass.

You can attempt primary bonding by fairing while the boat is not fully cured or working on green epoxy.
Or, you can sand the surface using the thread as a telltale and realizing if that thead vanishes, you have sanded plenty. Then follow sanding with fairing and the dreaded longboard.
You can try a weavefill approach, but I would not weavefill the knitting. It would be pretty deep..

Re: Panga 20 Build
I see the stitching your talking about after my splices cured. So, sand it down until the stitching are gone. Won't there still be areas that will not get touched by the sander. Does this matter?fallguy1000 wrote: ↑Sun Jan 13, 2019 11:38 amThe sanding generally touches off the knitting or the stitching in biax. That stitch is a telltale and not part of the main fiberglass.
