How much more is the Galvanized option?
You really think it 3-4 times the work, I dont see it sorry as being that much more.
But if budget is tight then I understand. Whatever you decide its your car and you know how much you can afford.

I totally am not the right bloke to ask about welding.
I do it but if I tell you I actually prefer stick welding to MIG you'll know, as will anyone else, that I must be at the veryu least a bit weird.
It comes from fabbing bits for kit cars which are made of feck off thick metal.
I have welded in metal in rusty footwells but any proper welder would fall about laughing at the bits of mig wire that went through gaps etc and had to be ground back.!!!!!
That's exactly the plan. The problem is that last bit! The only GOOD mobile welder round these parrrrts is no longer available.You could do all the work, fit the 1/2 chasssi, then get a mobile welder in?
I didn't know it was poisonous! I did a lot of welding to get my old trailer fixed up recently, ground off the galv and welded. Maybe that's why I was seeing dragons in my shed afterwards!Not forgetting that he'd possibly have to do something about the galvanisation so as not to poison said weldery bloke!
Welders don't like galvanising - as Stanleysteamer says, it gives off lots of very toxic fumes while welding & I think needs more skill to weld through.
For info I think the 2200mm section is probably a lot more work than eg a 1400mm section & requires a lot more care as you're removing the rear axle / radius arm mountings - so alignment is a lot more critical to ensure the rear axle is aligned properly.
I was surprised how easy it was to fit a 1400mm rear section & the only alignment issues relate to body mounts - which are nowhere as critical as axle mountings - but are relatively easy to align as the body mount is the datum & is still in place when the chassis section is being welded up.
Making sure the new axle mounts are in the right position I could imagine being a challenge !
I was surprised that despite the old rear (higher) section being really rotten, the area round the longitudinal arm mountings was in really good condition - even though it was full of sand & grit from various wading while off-roading repeatedly. On our TD5 it definitely didn't need more than 1400mm replacing.
Hi I have had a look at the video and stills thats very similar to mine which I did last year,I cut an shut it with a 1/4 chassis section no rear suspention to take off it tooke me a few days, hardest bit getting the fuel out
it does help when your a excoded welder like me but its realy not that difficult the body is normaly solid so before you weld it bolt it back up to the body to line it all up, with a 1/4 section there is enought access to weld the top , I suspect with a 1/2 section you will need to either cut an access hole to weld the top or remove the complet body to weld the top, still once its welded back in place the carpets will hide it, the main problem I find is the vast amount of underseal on the inside that takes a lot of effert to remove before cutting and welding
Yep that's what I was hoping, grind off the galv before welding. I spoke to fabricators today and they are a welder down so ETA for a 1/2 chassis is now 80+ days, depressing especially as my MOT has expired now, gonna need some trickery to hide the hole and keep it on the road until it arrives, so I can travel a mile down road to drop son at work a few times a week!yes welding galv is not nice , but you can just prep the ends by grinding off the galv then weld then piant with zinc base paint the weld area
Really? Where from?£2k get you a new galvanized D2 chassis.....no welding required
That chassis is worse than mine pre welding
Nice to see the ARB pipe, most part chassis stop before that.
I ripped an ARB bracket off mine.
My chassis is worse than yours was? Yes it's deterioriated fast here, scary fast.
Not sure what an ARB pipe is, but yes I want this longer one to get past that cross-member and well past any scaliness/rust
Google metal fume fever.
So long as last inch or or so galv is removed then that is good enough
As for a good welder, an average one will do just fine, measure total length of weld 2xside top +bottom, and I bet you are getting on for two feet of weld each chassis rail, so even poor welding will hold that just fine.
but that may not be true, first you need to know the type of joint, with a 1/3 section it slips over, so it 2 x side, top +bottom , plus the 4 corners, and 3-4 plug welds on the sides for addes strength now if its butt joint, I would plug weld in side plates on the inside of the chassis to add strength or the other was is to weld on external fish plate to add strength

Tbh I think the welding will be the easy part of that job.
Ha, that's pretty much what we discussed. When I thought it would be two butted ends, an internal plate both sides or a box section to slot inside was the plan. But now i know the chassis comes with flared ends (its bigger box than original) so it slots over and overlaps around 5-6 inches which adds a lot of comfort! I would probably seam weld right around (if i can get to it all), and then add a fish plate (only learned that term yesterday!) on both sides as you say.but that may not be true, first you need to know the type of joint, with a 1/3 section it slips over, so it 2 x side, top +bottom , plus the 4 corners, and 3-4 plug welds on the sides for addes strength now if its butt joint, I would plug weld in side plates on the inside of the chassis to add strength or the other was is to weld on external fish plate to add strength
I didn't understand the first line at all. Are you saying welding downhill is not as strong as uphill?As to the art of welding its no all down hand at some point it either vertical up or stove weld down, up is stronger unless you roll the car over and keep it all down hand
as for slotting over this was how mine came, you can clearly see the ends have not been welded and it slips very easily over the original chassis at the cut point
