Galvanised steel.

Yes but you must grind back all traces of zinc, if you do not the weld will splutter and not be any good and secondly you will inhale terribly noxious fumes.

In practice even when it is ground back there remains some in the heat affected zone and it always gives me a terrible asthma attack, the only other thing that does is spraying 2 pack paint.

Dependant on the thickness of your sheet (perhaps it is plate?) you will not realistically be able to grind away the zinc and have any metal left.

Use a mechanical or bonded joint.

Hi Gents, ta for the quick reply!!

I will pop me rivets and not pop-me-clogs me-thinks! They are good aircraft quality rivets, ex R.A.F. in fact and have got to be near antiques as I 'aquired' them in the late 60s, early 70s!

I am using an angle grinder with a diamond stone cutting disk to cut the sheet, 2mm thick. I bought 3 from Eleclerc about 4 years ago for 8€ and so far they have cut just about everything from terre-cotta to stainless and I can't wear them out! Then again I always buy the best [Www]

Break stem or break head?

Even cutting galvanised with a grinder can poison you.

Do you mean Avdel pins?

As an ex-race car constructor I have boxes of them although I havn't seen them for sale for years, I showed mine to some of the aircraft assembly guys opposite me, they caused quite a few raised eyebrows, these guys are not even allowed (or capable of) to sharpen a drill bit, all of the pedestal grinders have been removed, when they blunten one they replace it with a new one from the stores.

When I wanted my planer blades sharpened I had to find someone who could still access the old tool and cutter sharpening equipment.

The cutting was done outside my workshop in a stiff breeze and I was wearing my new toy, a Powercap Light pos pressure face mask that stopped the crarp (?) hitting my face (I wear safety glasses as normal perscription glasses all the time). A lovely bit of kit that new toy!

The rivets break directly under the head and as an ex aircraft electriction I didn't learn the difference?

As far as the gripper pins are concerned, of course I have the correct ones! Both for 1/8th and 5/32ths! Wot do you think I am, a filleystyne?

Avdel, wot on earth else?

I am afraid that my old Tucker Pop rivet pliers are getting a bit too old and loosing their grip, a bit like me I suppose? I am going to have to see if I can contact them to see if there is any way I can bring them back to life? If the firm still exists that is?

Those pop rivet pliers are exactly the same as the ones I used to use when doing Cat 3 aircraft repairs, but the gripper pins are the old type. The newer ones had a plastic sleeve on them  - yellow for the 1/8" and blue for 5/32". Avdels are completely different and stronger but used in aluminium. The pins could be inserted into the avdels after fitting to give them more shear strength.

I have both the old and new type although most of the plastic sleeves have now melted, they dont make em like they used to.

I also have an Avdel thin sheet nutsert kit which cost me an absolute arm and a leg when I bought it but has served me well. Like most of my specialised stuff it is mothballed in my UK workshop untill I will be once again a man of leasure.

The abiity to access specialised tools,equipment and fasteners, indeed even being able to discuss it with people who know what it is and where to find it is one of the things that I miss most about England.

Looking back my first contacts with the French was getting them the bits that they couldnt.

How about a photo of a Hank anchor rivet bush guys?

To think that I used to be able to drive 5 minutes and pick up anything like that from the RS tradecounter, albeit at a price [Www], that will nevr happen in my lifetime in France.

But I was surprised to see a rivnut gun available in Leroy Merlin......

That impressed me about France and the availability of those litte parts to repair things whereas in the UK you would have to buy a complete new unit.

My Avdels are the old metal ones, never seen a platic pin/sleeved version.

Haven't used Avdels for a long time.  Cherrymax are the preferred spec these days http://www.cherryaerospace.com/html/product/blindrivets.html since they have a hardened locking collar within the head for increased joint stability.  Bit of an art to removing them though you have to drill off the collar with a small cobalt drill then drill off the head with your shank dia drill.

Modern grip pins are either the plastic sleeved ones which come in red, yellow, blue, black, white http://www.skinpins.com/fastmotemp.html or metal spring loaded Cleco's which come in silver, copper black or brass http://www.skinpins.com/fastclecotemp.html.  The Cleco's are ace for speed of work but when you need to pull down a joint to squeeze the fay sealant you just can't beat the plastic sleeved ones - the plastic piece butts against the metal to prevent it from being damaged.  I tend to use a mix of the two....

As for rivet guns to install yer Cherries, hand pullers are ok.......but I much prefer one of these http://www.yardstore.com/browse.cfm/4,5660.html

Well, finished artikle folks! It went in like a dream. I used a ratchet strap to form a circle (steady there matron may be watching?) and 2 pair of Mole grips to hold it all in place. Then it was just a case of dropping, or should that be lowering, it into the hole to sit on top of the fibre glass tank and use self tappers to hold everything where it should be. The white line is silicone sealer to finish the seal.

Why thank yew my leetle French Teapot!

The stuff is Silkabond Universal solvent free and it don't smell like citric acid, so I guess it's OK. It says that it's OK with all metals too. I didn't know that sillycoons had a taste for steel, so ta for the info!

No probs Chancer. They ain't Wichardz they is wockz, rocks to you and me. They do the final filtering and they start off pink and when they get to be black they need changing cause they are full og bull you might just say?

[IMG]http://i47.photobucket.com/albums/f180/Jonzjob/Galvanisedfoss3.jpg[/IMG]

It isn't full to the brim, it's just full to the outflow pipe and that is a baffle in front of it. There is all sorts of life forms rushing around in there too. Quite fascinating if you like that sort of thing. In fact although it is a bit smelly it ain't bad at all compaired with what goes into it! The inflow pipe is the same level on the opposite side and has the same type of baffle on it. The reason is to stop the 'stuff' apearing one side and shooting straight across by the short cut!
