Hey silly, good timing there. I’m just at this stage with some blanks I’ve cut from a block.
Q. With the 5min epoxy do you have to have a really smooth cut for the stringer to stick to? I figured on using Gorilla glue to fill some of the beady gapage (roughness) in the foam, but can’t find Gorilla glue anywhere near me. (No gorillas to stick it with I suppose).
when people talk about PVC stringers - are you talking about a similar material to the PVC baseboards that are used in home construction – here in US at home improvement stores you can buy various thicknesses of white PVC trim to finish out a room in your home – wood is also used, but PVC is cheaper and lighter - is this the PVC everyone refers to? thanks!
go with option 1 like silly says, less hassle and only 10 extra mins to cut twice. I use sumo glue instead of epoxy or gorilla, it is PU glue but does not expand as much as gorilla and is white and sands out easily, unlike epoxy. sumo is made by locktite, not sure if it is avail in US or NZ.
PVC foam is generally Komatex or Sintra, it is used by sign makers.
I vote for option 1 as well. You’ll cut the EPS twice as fast, so it won’t be like double the work to cut two halves. You’ll get a better result with your rocker templates only 12" apart - less wire wobble or crown.
On 10’ boards, I can’t get the whole thing done with 5 min epoxy. But I agree that, as much as I like pu glue, this isn’t the right application for it, since it expands & presses everything apart right where you want it to be tight.
The same stores that carry 5 minute epoxy usually have a 30 minute version that’s packaged the same & everything. That would be my recommendation… no need to stress yourself out. You can do both halves at once, since you’re gluing the stringer to a factory edge.
