HELP!!!!!

Hey Guys

Just routed the fin plug holes for my new 9'0" EPS/Epoxy longboard.

Used double sided tape to hold the jigs in place.

Holes turned out fine.

When I pulled the jigs up, the tape caused the glass to delaminate a little bit around the plug holes.

I'm hoping that when I intall the box, the resin runs into the gap and bond it again.

Having doubts about that though.

Anyone got any suggestions????

I used spackle to seal the blank and it seemed to separate fairly easy.

Wonder if an epoxy/micro-baloon seal would have been better.

Maybe some inserts in my next one.

Please help

Cheers

 

Hey...you'll have to give more info...

 

What fin system, how much area of glass has pulled up, has it sat back down flush?

The fact that double-sided tape has pulled up glass is very suss. What was the spackle?

Hey Josh

Fin system is Motivation Lines. boxex are similar to aus fin co accept there are straight.

Just use a plastic jig for the router.

Only a few areas around the hole but one is about 1/2 wide x the length of the hole.It has sat down flush but you can see it.

Spackle was Red Devil, One Time. Only applied it thin and sanded so the EPS ball start to show.

I'm with you, a bit sus

Hey MDS...been at work. Sorry its been all day...

Firstly, can the red devil spackle...I mean...PLASTER!!!??? Not.

 

I don't do any installs straight up against EPS, whatever the density. Its a liability. High density inserts every time.

You should be able to lever up the delammed bits a little with a blade and get resin in there. I'd do that separate from the mix you do the boxes, so you get a chance to weight down the delam. Plasic over the spot and a padded brick...

Hey Josh

Yer, I was reading through some of the archives and someone (cant remember who) said the he uses a syringe to push resin through a straw. Sounds like a good idea as you can flatten out the end of the straw so you dont have to lift  and cause further delam.

I will do the epoxy/ballon mix next time

I think that inserts may be a think of the future for me. Been thinking about making up a couple of jigs. One for the insert and one for the hole to fit the inserts. If I can get it right, it should be a perfect fit every time.

What do you use for inserts??

Cheers

 

 

hey MDS,

I'm with Speedneedle about the inserts. I never set boxes or plugs into straight EPS. I have set plugs into VH EPS and i was abit worried about heat etc. Any type of HD foam will do corecell, d cell, klegecell etc. even offcuts of surfblanks red foam.

Qcell and epoxy is the best bet for sealing. When I use that and set boxes or plugs the foam comes away with the glass from the routed section.
