JB Mounting Methodology Help!

Looking at doing a complete re-wire on my RIB. Everything ordered and doing a proper job on this one. However, the existing JB is on the deck inside the console. I'd like to mount the new JB vertically, up from the floor. However, trying to decide on how to do that... I don't want screwheads on the outside of the console so need a completely internal mount - but, all of the surfaces are curved.

Have any of you made up mounting frames or bonded a sealed ply backing board to the bulkhead/console walls?

Any help welcome! Pics, etc more-so...

As simple as that? Doesn't vibration and moisture effects eventually cause the whole lot to come apart? ...always been a mechanical fastener kinda guy...

I'm with you on the mechanical fixings, BUT I've been using Stixall at work & I'm very impressed. About £6 a tube.

The gripping power of this stuff is emence I have done pull off tests at work and achieved 900 psi it's got it's own shock absorption, designed for in water use and it's holding hardly any weight if it falls off clean up and reglue. Do a trial prep a couple of pieces of plastic stick together and pull apart after cure. I was the same always used bolts until I removed my jockey seats and found out the power of this stuff. If you want to remove it like I do stick a block on the side wall and screw to that.

You could bond a couple of bevelled hardwood battens on the console and then screw a ply board to that to mount your JB to.

In terms of adhesive, I tend to be a snob and use either Sika 292i or epoxy with microfibres for bonding stuff but as others have indicated there are probably a few similar but cheaper adhesives on the market.

The key (pun intended) to getting a good bond is the preparation of the surface. Sand the surface of the console in way of the battens and then wipe the surfaces with acetone to get rid of dust and any grease.

If done properly, it is a permanent bond which you won't get apart without destroying either the ply or the console.

Could glue in a couple of bonded fasteners and use wingnuts to hold the box on. I'm doing something similar in mine currently

Another thumbs up for the adhesive qualities of sika flex, itís what they use to stick windscreens into cars. Itís also flexible so will absorb vibrations and fully waterproof. Just a bit of a pig to get off in future!! - usually end up shaving it down with a razor blade.

The Sika remover is for uncured product only - acetone works OK as well. Once it's cured, you can only remove it by mechanical means.
