Installing hull serts for tank mounts and water box

[air blair]

Scuff surface with sand paper. Acetone clean both surfaces. Buy Ufo mounts from JetManiac.

jam clay in both sides. Adjust level off hull with clay. Keeps thread from getting resin in them. Mix up some epoxy or I did ve resin with glass spheres, cabosil, and 1/2 inch glass chop. Can add pigment for coloring.

lay Ufos nut up and squish into the peanut butter consistency putty. Cut some thin glass and put a hole in middle. Use the glass to smooth the putty into a tapered to nut surface. Once you have that done

apply resin as you would to regular glass and finish smoothing it over.

to finish it off after it cures sand off flush and run a tap down by hand to remove clay. Hope this helps someone. That's the purpose of this share. Have fun.

Dam Blair! Giving all the secrets away!

The only thing different l want to try this time,is cutting the carbon into a perfect circle around the insert.Guess l'll get the shears out and try a few

Nice tech help for the guys that have never done them!

 

[air blair]

Right on brother. No sense in head scratching. Lol. Circles actually turn out very nice too. I just had so many to do. And the insides will be painted in the end on these. In a pinch a squirt tube of epoxy or waterweld will get your Ufos in on the beach.

You can get some veil cloth and 3M 77 spray adhesive adhesive. Spray the adhesive on the back and put the veil cloth on the back then let it set up.

Now you can cut your carbon kevlar with out it fraying all over. It still will a bit but not very much.
Thanks for the tips on the mounts Blair!

Shoot you could veil both sides of that specialty weave. Upon wet out it will provide waterproofness. Carful on too much adhesive the resins won't break it down. Just a misting. Will do

I found a site that has carbon fiber veil cloth instead of fiberglass. If you read the info in the link it has some cool uses.

Do you then pull the veil cloth off during layup?

I was using a stud waxed with mold release. I'll give the clay method a shot.

No veil cloth, just spray adhesive.
No the veil cloth stays on. If you check the link out it explains what it's good for. It's good for building or hiding the print.

If you don't want to use veil cloth just spraying the back with the spray adhesive works too. Just give it 20 minutes to set and you can cut it. I found that out later. I stumbled across that by accident

I go one step further and vac. bag a couple layers of 20oz carbon over the incerts. I use the clay method usually and milled carbon/resin past.

Anyone use plexus instead of resin?

 

[Yami-Rider]

I don't see why plexus wouldn't work, just kinda pricey.

Excellent tips. Thank you sir!

Funny you mention that. I recently purchased a setup for vacuum bagging. I had to make some repairs to a propane tank enclosure on my toyhauler rv this weekend. I figured it was the perfect time to practice before I do anything on my skis. Some mistakes were made and lessons were learned. I'll be bagging everything I do from now on I think.
