My only update is that AZZ says “No”. If I sign a waiver saying any damage from galvanizing or from sloppy handling is not their fault then I’m OK. They are an industrial shop— they don’t want to have an ibeam hit it and be held responsible. I’m gonna build a frame for the bulkhead, sign a waiver, and go for it but it’s down on my todo list.

I sign a disclaimer for every bulkhead or part that I have dipped here in the UK. I do all of mine in jigs and never had damage. I had to convince them to dip my very first ones as they hate dealing with LR owners and jack the prices up to avoid dealing with them. Once they saw mine in the jigs they changed their tune. Now they actually prefer how I bring them in the jigs as it makes their job easier. You may have to fab the jig in a way so that it hangs at an appropriate angle when it is dipped to prevent any pooling of the zinc in the footwells. At my place they tend to hang like for like when dipping, meaning that it is very unlikely they will hang structural steel on the same frame as your bulkhead when dipping. I think you will be fine.

That’s good to hear, I have some bumpers I wanted to get dipped this summer and maybe some rover parts this fall. Depending on how your jig works maybe some locals can reuse it?

I have a plasma CNC table if there are any brackets or parts that would help to have CNC cut for a jig, combined with some sheet metal bending CAD tools you can make some really nice parts fairly easy that could help. Let me know.



That’s good to hear, I have several parts I was wanting to get galvanized soon. I will be curious to see your jig, build it right and maybe some of us locals can reuse it.

Same story. Blah blah blah if we ruin it it’s on you. I’m not really excited about paying for another bulkhead plus shipping, but not impressed by the thought of a rusty one either.

I have had one shop agree to do it, but they want to drill extra holes in it. I’m fine as long as they are not visible externally.

I had two come back with holes.
They mistakenly believed the door pilar was closed @ the top, they are not
I welded up the holes and moved on.
The reason holes are drilled is to allow air to escape to prevent ballooning.
To be clear, bulkheads should be dipped upside down.

Good to know, thanks! Are any holes beneficial?

Good to know on the upside down thing. I can only find one galvanizing outfit that will do it- and they are hesitant at best. Any ideas on where I can get ‘instructions’ on how to do one? Are there other options for rust proofing? My Defender is heading to the USVI so it needs to be as rust-proof as possible. I’ve heard of epoxy dipping, could that work? It’s a brand new factory RHD Puma bulkhead.

Thanks in advance!

Paul.

Thoughts on epoxy coating on a bulkhead? I can't find anyone in the PNW who has galvanized a LR bulkhead but I have found a company that will strip & epoxy it.

Paul, contact Ike @ Pangolin 4x4. I'm pretty sure he has bulkheads galvanized all the time.

Tactical4x4 started "metalizing" their large parts such as bumpers, sliders, etc a few years ago. I looked into it and it appears it's a zinc spray plating process. The company they link to for more info is on the west coast and looks promising:

Quote:
We Hate Rust!
We are so confident that our metallizing process will keep away rust that we make the following guarantee: If your pieces are metallized by us, there will be no visible rust for 3 years! No steel erosion for 10 years or we will metallize your problem pieces again for FREE!* This means that metallizing pays for itself in less than five years!

ZincNation, Inc
Quote:
The surface to be treated is first sandblasted. Then wire is fed automatically through the nozzle of the spray gun. A combustible gas, oxygen, and compressed air serve to melt and blow the atomized metal against the surface to be coated. The preferred gas is acetylene although other gasses can be used. For corrosion protection primarily zinc or aluminum is used. Zinc or aluminum, powerful anodes, on steel or iron create a cathodic or galvanic effect that resists corrosion. Rust cannot spread and blister your paint even if the paint, primer, and metallized coating are scratched, all the way through into the iron.

Hey Davis,

I don't know if you have get this sorted but I will be running another batch of parts including a chassis through the galvanizer this Sept. I'm happy to add the bulkhead in if you want to ship it to me in Nashville. Shoot me an email off list and we can chat. [email protected]

Cheers
Scott

Thanks for the offer, Scott--but the back and forth in freight just isn't worth it--I'll get it sorted here though.

Sam--I'll reach out to you in regards to reusing the jig--no issue there.

UD_-GREAT to know about doing them upside down, thanks! Curious as to why? (I know your experience tells you so, but would love to know what goes wrong!). I'll put a lifting point on the jig to make sure of it....

any pics of your jig and/or dip setup? i assume you have to pack it out a bit to allow the galvy get around where the jig attaches? just curious as I have not ever seen anything galvanized other than some industrial ibeams when i was at a finishing shop. thanks.
