1994 Hydrodyne stringer job

So I found Doug fir locally for 38 bucks a board.

I also bought 5ftx 40ft of 1.5 oz chop strand glass from my fiberglass guy. He said I can't use epoxy resin with this stuff but I don't need epoxy? Reading on here that epoxy resin is better?

He said to do about 4-6 layers of the 1.5 oz glass for the stringers. How much resin should I expect? Start with a gallon?

I was hoping to make my cpes with the resin and xylol. Does this still work with poly resin?

I have been reading other threads but i get lost in all the fiberglass variations (epoxy, poly, vinyl, cpes, pb, different kinds of mat, different kinds of epoxy) ive never done any fiberglass at all.

My family friend who does fiberglass and sold me the chop strand glass is confident that i will have no problems using poly. do you guys think i should be doing something different?

can i use poly resin over cpes?

Yes CPES will stick to poly or epoxy . US Composites is a good source of information and material.

So should I not be listening to my friend and got with 1708 biax and epoxy instead?

This is starting to get expensive

Is this what you guys suggest for layup scheduled or could i get away with just doing a couple layers of 1708 on the primary's and one layer on the secondary? if i choose to go that way.

can you send me name and phone number of source of douglas fir lumber thanks dan

So i think im going to go with the cheaper poly resin.

I called jamestown and they said poly resin will stick to cpes just fine if i wipe it down with acetone and give it a light sanding before hand.

So im going to have the cpes keep it waterproof and let the doug fir give me the strength. the fiberglass just needs to be strong enough to keep the stringers to the hull.

I can tell you anything will be better than how it is now and how ive been running it the past few years...

Im also going to be doing such a better job of sealing the stringers than hydrodyne did. i cant believe how much exposed wood there was on the stringers. they stopped fiberglass about 4 inches from the transom and just left it exposed. they put so many screws in the very bottom of the stringers to hold a gas line in place so it didn't take much water in the bilge to soak the stringers.

I guess ill let you guys know in ten years if im doing it again or if you guys all fell for a marketing trick.

In order to properly glass in the floor, the strip of wood needs to come out. Anything other than very light glass won’t get into the space between the floor and the wood strip. I am assuming you will have some mat on the floor surface.

thanks guys. those are gonna kinda suck to get cut off...

you can see them in this pic circled. its what the cargo net screws into.

Very nice job. I’m gonna copy your work someday

So i took the oil pan off this weekend and everything under it looks fine including the pickup. I dont think anything was touched.

Im gonna try to bang it out this week and get it back into shape and maybe jb weld or have the welder where i work fill any holes but i dont think there are any. unless that seems like a bad idea to you guys...

Im going with 2 layers of glass on the floor with 2 extra layers of strips around the edges. today, cut some holes for the ski locker and wires to go thru carpet latter this week and put her all back together on Saturday and hopefully a test drive on Monday!!
