Plexus

[Mdavies_02]

So I popped two hull strap inserts outta my Freak this weekend at the Wasaga Freeride and am looking at getting supplies to adhere them to the hull. I have West Systems epoxy resin with hardener but I was told that plexus was the way to go. Searching on the forums I found afew mentions of the product, but nothing ever official stating an item number.

Just want to confirm that this is the right thing to get, and it is a better option then regular thickened epoxy.

Thanks in advance,


Mike

Plexus is good but good plexus is expensive. I wouldnt use 310. The 10:1 is better. What the hull builders and knock off brands are im told.
Hit up JetManiac for ufos or not sure what ur using but i have some killer zip tie mounts we carry. You can plexus or urethane them on. There are photos on my builds. Been using them for years. Zero failures

Plexus is good stuff for sure. Once you glue something down with plexus it will never come back up. Hull builders use it to glue in motor mount inserts and possibly other inserts. It's not cheap stuff, but I haven't found anything that's quite as strong.

I would rock G-Flex for inserts. Plexus is specifically design for composite to composite bonding.

I've had good results with 3m panelbond for these applications (alternate option). Can be found at local autobody supply shops for around $40 a tube. It uses a tube specific gun like plexus but for small amounts I cut 2 equal length pieces of pvc to push each plunger then mix with a screwdriver.

Ma832 is the way to go. I'm having good luck with the ma300, but a fellow rider recently had failure running it on strap mounts.

Fyi the zip tie holders are composite material. :0)

Totally agree with @BrightE's on the use of G-flex.Used it for 6 different builds with ZERO issues.Jamestown Distributors

This also doesn't include the cost of the~150$ mixing gun required for the 380 mL cartridges. Anyhow, I bought MA0420 and have been happy with the results. I used it for structural bonding of composite parts.

See the product selector guide from ITW (manufacturer or plexus).

Will this keep the ufo mounts for tank straps connected to the hull?

Yes,l let the Gflex dry overnight and l always cover mine with thickened epoxy and then a layer of 5oz. carbon.

I forgot to mention the cost of the mixing gun. Also, once you crack open that giant tube, you have less than a year to use it all.

I am using West Systems Six10 for all my inserts and to bond my new hull together. Amazing price, less than $25 a tube, super easy to use (standard caulking gun to dispense) and it's really easy to work with. Smooths out really nice when bonding and works great for the inserts. When I did my inserts, I gobbed it on, let it set up till it was starting to firm up and just shaped it around the insert. Once it was fully cured, a little light sanding to finish the shape and rough it up and then a layer of CF over it for peace of mind.

How did you go about drilling the holes for the inserts.

I filled the insert with red modeling clay to keep the epoxy from getting into the threads (Thanks to TOBY for that idea). Then after I laid the CF over it and everything cured, I used a countersink bit to drill through the CF putting VERY little pressure on the drill. It centered itself in the hole and that was it. To remove the modeling clay, I pushed a basketball needle into the clay and gave it a quick shot of air with from the compressor, the clay pops right out. I ran a tap into all of the inserts to make sure the threads were clean after that.

^I've used the same process and countersink bit but used earplugs to prevent resin from going in the threads.

Earplugs are GREAT for this. At work we use them to plug lube fittings during a disassembly (3000 HP frac pump). Pinch them down, stick em in a hole, and they expand and stick. Just remember to leave enough sticking out so you can remove them and they don't get forgotten.
