Super Jet Quick Foothold question

[paczowski123]

Im about to start my foothold install, and had a quick question about sealing them up. I was going to go the rivets and 5200 route, but it seems many have claimed the 5200 is not a good choice and to epoxy them in. My question is what is used to epoxy them in? I have US Comp 4:1 quick dry epoxy resin, so do i just use this to epoxy them in, or do i need to mix something else in with it? I also, have some cabosil, but have also heard this is bad as you cannot sand it. I will be ordering some glass cloth from US Comp here shortly, so id love to order it all at the same time?

rivits to hold them in and glass the crap outta them

I want to use a type of sealer for the seams though before i glass them over. All of my friends have used 5200, but i've seen a lot of people warn against it. I was going to rivet them in, use a epoxy for the seams then glass over it. Im a bit of a over-doer, but i like to do it right and do it once.

Sand/rough up gel coat edge around hold and hull mating surface, pre drill , I use 5200 around the rivet holes and thin bead around perimeter of the hold, set and rivet. Then I mix some epoxy resin with micro balloons or cabosil, like peanut butter thick , spread around edge or lip of hold to seal and make a nice feathered smooth transition, wet it out that way you can lay some glass cloth over all of the rivets and let it set up. I like using 5200 as sometimes glasswork is often not fully water sealed and seeps into the tray, even when it is rock solid.. Extra insurance my.02 cents

 

[paczowski123]

Yeah I may do that as well! Thanks for the tip, I just had heard Cambosil gets so hard you can't sand it, so didn't know of it would be ok to lay glass on properly...I may still run a bead of 5200 around the hull as I set it in and rivet it

By doesnt sand they mean doesnt sand like wood or foam. It will still sand and for footholds where its covered, how it looks is no big deal.
Im not sure about the 5200 and epoxy does epoxy stick to it? If you do a good job with glassing it shouldnt leak.

 

[paczowski123]

Well, I'm more worried about the epoxy/cab work first as this will be my first glass experience and won't be perfect. I've used bondo and am familiar with that so figured the cab/epoxy substance would be familiar to me as far as laying it and working with it

 

[IS0LD0UT]

Dont overthink it. If you can do bondo work u can do this. Epoxy and cabosil is not concrete.

Glass doesn't always seal water out because it can have pinholes in it. The weave isn't always perfectly closed. So unless you lay multiple layers of tightly woven cloth, and then seal it again with resin, it still has potential to leak.
Make sense?

 

[Roseand]

Dude, I never worked with cabosil, glass, or any kind of resin before I did foothold. Well, 5 minute epoxy was my only experience with resin LOL.

I was super nervous my first time glassing footholds, but I did use cabosil to glue the footholds in.. Super easy, mix it up thick like peanut butter and you'll never have to sand it because it's so easy to spread around and shape it flush against the holds. It's no big deal.. Glassing in footholds is pretty simple, especially with tightly woven cloth(much easier then messing around with reinforcing with biax, etc, in hard to reach areas. Footholds are much simpler).. Just put multiple layers of woven cloth glass and you'll be good, and I believe you can mix up some resin later when the glass is cured to seal it up too. You'll be fine!!

 

[paczowski123]

Yeah I'm sure I'll do fine just like to have everything planned out before I start anything. I've rushed on too many things and screwed up so I like to make sure I've got my process down.

One other question I do have is regarding the two part foam. I only plan on cutting a hole just large enough to put the hold in. Many of my friends dug out a lot of their foam and added two part. Do y'all think it's better to dig it all out and add two part of leave it how it is and only dig out what's needed?

 

[Roseand]

What kinda holds are you installing? If you're holds are flimsy, foam adds some support to them. If you do cut a small hole to pour foam, just make sure you seal it up real good.

WCF holds...they are not very flimsy, but I guess it's not too much harder to dig it out and pour some in

 

[Roseand]

Then it's not necessary, but up to you. Just another possibility for foam to get wet.
You have a mint square that's like never been used tho right? Foam might still be dry then.

I always dig foam as tight against the hold as I can. When I get close I will take small piece of foam out and re fit that way filling a void is not necessary.

 

[paczowski123]

Yeah I just finished up cutting and deforming. I'm going to use the two part anyways it's not that much more work I just drilled a hole and made a passage for a funnel to go down into the cavity. There was some water in my tray foam which was a real bummer, so I'm going to leave it cut and open for a while to hopefully dry out some. I don't have any desire to refoam and glass the tray.

 

[Roseand]

It won't dry out, but if you're not concerned about weight, don't worry about it. If you defoam, depending on your riding style, you might as well reinforce the inner gunwales and cut up sheet foam and install drain plugs since you're already in there. That adds a TON of work though.

 

[paczowski123]

Yeah I know it won't totally dry out, but if I let it sit a few weeks some of the water will evaporate. I didn't wanna seal it right back up without letting it air out a bit. I will probably take it to my friends garage that runs a dehumidifier as well. It was amazing how fast it would suck the water right out of his bilge in a matter of a day or two from the air being so dry.

Being as I still run a square nose and plan on going AM in a year or so I don't plan to put much money into this hull otherwise I might consider the refoaming and reinforcing.

 

[paczowski123]

I do have one more Q though for y'all familiar with reinforcing. My ski will be totally stripped as my motor is out for my jetmaniac/blue ported 735 kit I'm doing. My question is whether I should go ahead and reinforce the sides of my ski? I will never likely do surf, and I really only plan on my hull being used for another year or so while I build up my fund for my AM hull. Would it be a good idea to go ahead and reinforce, or do y'all think it's ok to leave stock for flat water? I'd love to attempt some rolls etc this year but didn't know if reinforcing is necessary for flat water. Figured bows my chance while it's apart if it's necessary?

 

[schicks]

usually cracks happen in the gunwales when learning to roll. I would say leave it and run it, then up grade like you say. No sense in reinforcing a nice hull when you plan to upgrade within a year. Also, you may be able to dry the foam out a little, but if you don't take all the foam out and seal up the ride plate and pump inserts, it will get water in there again. The tray is not sealed very well from the factory.
