hi mm,
thanks for help.
so wing has to come off. then repair b-post JP etc then fit a new wing/ wing section.

Im trying to decide wether i should just get it thought MOT and use it for the summer or start all the work now. the seam above sill on the drivers side also needs work as does the sill closure plate inside.

I hate bodging things tho and to just put the tank etc back on for the summer when there are big holes will just annoy me. But i suppose i could sort the B post and JP out in a couple days/eves and the get new wing on and dont have to worry about it again.
I really am crap at making decisions.

Someone has just mentioned the idea of bonding the wheel arch on using panel adhesive. Sounds like an interesting idea.

[Plasticman]

well i dont know who suggested that but they can keep it to themselves :roll:I just dont see the need for it, there is nothing that cannot be accessed and welded,

[Plasticman]

oh and your hole for the belt , use anything to make it abnd it wants to be big enough to accept the spacer under the belt

[benlawlor85]

Ok ill stay away from bonding panels. Going to cut the arch off tomorrow so i can repair the B post and JP.
Ill then order new wing and any other panels i need on monday. where do you think is bets for panels mm?

[Plasticman]

unless you can locate a mint cut or a gennui££e one then they are all the same, even the sellers laugh when enquiring as thery bagree they are a rubbish panal but cant do anything about it, which is why i go to so much trouble to remove the arch and repair them
schofields seem worthy of support at the moment as they are trying hard...

Hi,
Well i attacked it today. the welding went really bad no penetration then blowing holes! grrr.
I removed the sill closure plate so i could access the inner sill. the other sill has been badly repairs so that might be next, also the C post has no bottom to it again badly repaired sill hiding it
anyway some pics below. i cut part of the arch off then repaired the end of the chassis, and the lower sill above the JP, the JP seemed fine.
One of my problems is that im using metal from an old mini lab, which is much thicker than the metal on the van so when trying to seam weld i blow holes in the van metal.
What thickness of metal do i need to buy to repait the b post and sill and where can i buy it?

Lastly i see to be useing loads of gas. am using the big hobby weld cylinders but gauge down by half in just a couple days. i am slow at welding tho... what lpm do i want im running at about 10lpm

Cheers

hmmm, dont know i just set iot where it works ,so been out and had a look , 4 to 6 lpm max is what i use ,are you using a flow gauge?
your doing fine there, i wish others would take as much trouble to post pickies
as youve cut it right open its an easier job really , what you need to make is the internal part of the B post and take this down to the lower seam then afdd the main stengthener that goes down the inner face of the B post, this then gives you the support for an effective jp, rest is cosmetic and up to you but your doing fine
metal wise for the B post and surrounding area 1.2-1.3 mm is fine for it, 1mm is a bit skinny, if you give me some sizes i can mail some down to you .pm me
mm

[benlawlor85]

so seems like i have been running gas at about 2x normal rate, i have a flow gauge on the regulator dont have a flow meter tho.
as for metal thickness i think the stuff i have is about 1.2-.15 damn hard to bend tho. and seems much thicker than any of the stuff im taking off. Its going to really hard making the more complex bends in the inner B Post with it thats for sure.

As for the main strengthener presumably this can be some some 1.5mm metal bent at the edges and plug welded to the inner b post.
Sorry for so many questions, but your help is invaluable!

Cheers
Ben

use this http://www.r-techwelding.co.uk/welding_ ... Flow_Meter" onclick="window.open(this.href);return false; or simmilar,
steel. 1.2mm is so easy to bend and cut are you sure about the gauge,
the jp support should be much thicker as it carries most of the load ive got a picky someplace of the ones i make but cant find it,
the inner b post is not complex, just about as simple as they come you only have to join the top bit so get that something like ,then it has to end just on the sill,then the strengthening brace covers the lot and extends down to the outer lip of the sill and has a scallop to fit either side of the jp;

Hi,
Not sure about the thickness tbh. i only have basic caliper gauge which aint really designed for anything that thin. Def no over 2mm tho. As i said its so hard to bend for the sill repair i had to hammer the hell out of it in a vice! and to weld it my welder is on full power (its only a little sealey 130XT) I will look into getting one of the flow gauges as it seems i have been running far to high. i am working outside tho which doesnt help!
Do you think i should cut out the outer sill where the seam has disintegrated now so i can fully repair the b-post from both side or treat that as a separate job.
