Next step was to reinstate the seam. This was to be done in stages. First I braced the seam with two bridges near the fuel tank to stop the seam splitting, then I cut a slot in the top part of the seam to allow inleting a T shaped piece.

This proved to be impossible as getting a decent fit was too time consuming so I welded over the join inside as for deseaming.

The only way to add a 'seam' now was to braze on a bit of steel. I brazed it to fill up the seam joints and waterproof it. Unfortunately I only had some rather 'agricultural' rods which were a bit big so the flow was not as good as I would like. Work on this is now stopped until some nice little SIF 1.6mm rods arrive.

Apart from a small section of gutter to braze on the corner repair is finished from a welding point of view. The welds were then ground down, another point to stress is don't use a grinding disc but a sanding disc on a flexible backing pad. The reason for this is a rigid disc will gring wherever it touches and if it is not accurately held will run off onto the panel. A flexi disc can be run over the high spots and will only grind the higher bits as it bends and can use a larger area of the pad without the need for such great accuracy.

Showing your age recognisng the tool that started the grinder craze. I inherited it along with a large number of 40 grit flexibles so I keep it for linishing, it's amazing how much closer to a corner a 4" disc will go when compared to the 41/2". On the down side what a crap place to put the switch.

Nice work Mike 8-)

We've always said that you can't beat having an oxyacetylene set up as well as a MIG for restorations, as they both have their advantages and disadvantages. Brass is great for sealing up gaps and for non-structural bits.

Shame that BOC screw us all on the bottle rental, invoice charges etc, having no choice to rent the acetylene from them as they are sole suppliers :x

Isn't there somewhere called Air Products as well?

Yes, but as I understand it Air Products cannot supply Acetylene - BOC has the monopoly on that gas !

If that's not the case, we'd be very interested to find out where it can be obtained as the rent is due on our bottles very soon !

Hobbyweld can now supply acetylene in small bottles, rent free but you have to put down a large deposit for the bottle, if you terminate the contract you get the deposit back less 10% for admin.
If I remember correctly a full bottle is £150 [including deposit] with refills £50.

Andrew, air products have supplied Acetylene since forever, I rented a one and one from boc for around 30 years when I was a contract welder until I retired , boc and air products are on pare with each other with prices , I think the only real advantage with air products is they give you 60 days to pay,
Boc 30 days, If you rent large amounts the prices come down drastically , so the poor old small garages , sole traders have to pay top dollar, I would not touch the little outfits doing the small bottles as in the long run it will cost you , Acetylene needs to be handled with care, there have been some serious incidents , if you have a fire and Acetylene is involved then get ready for some serious HSE , the building , garage or wherever it is kept will have 1/2mile radius evacuation around it, go to boc or air products and pick up a safety leaflet, google it and be safe.
Also fit a guard to that 4 inch grinder before you remove Your fingers, them machines don't take any prisoners, I have all mine but I have been close.

Thanks for that info and advice Goff and I agree regarding safety etc. I didn't know that anyone else did Acetylene but sounds like we may as well stay with the 'Devil you know' :?

Dad is/was a sole trader and only had a portapack welding set with the larger of the small bottles. When he got the portapack set the rent was £100 for ten years, now its well over that for a year. Having gone to the next size up acetylene bottle a couple of years back when there was an extreme shortage of the smaller bottles, the rent is even more. However the bottle is lasting much much longer.

He'd give them up if he felt able to but you can't do without them for restorations. Been using them this afternoon, along with my Migatronic and spot welder, on my pick up.

Anyway, sorry Mike for taking this bit OT :oops:

No problem helping out,
I rented the biggest you can handle , I think it was a w size acet and maybe H oxo , I reckon the rent was with vat £250 per year about 5 years back , then you paid for the refills , though I charged the customer for the gas and incorporated the rental as well , next time you are passing a boc agent call in and ask for the safety leaflet for both gases , oxo can be dangerous as well , a contractor I worked for had a incident with acetylene , it cost a fortune so they swapped to propane gas, but I am talking of flame cutting , as you know you cannot gas weld with propane , the gas is to cold but you can braze OK, if your bagging is cracked , damaged replace it ,it's not expensive nowadays , same with gauges and flash backs ,infact I think they should be changed every 3/4 years for insurance purpose , if you carry in a van then it needs a vent and bulkhead and the acet should always be stood upright .

More and more people doing gas now. I gave up my BOC argoshield bottles as I was being screwed for rental, gas and delivery. The final straw was being in a hurry and going to the depot to pick up a bottle and being charged £30 for the privelidge. Now I have got my gas from a local supplier who is a sub agent of Adams gas. He does 20l argo and its a one off £80 deposit and £50 a refill for 20l. Bit dear refill but no rental and can pick up free.
He can also do oxygen so I am changing that as well but does not have a licence for acetylene, anyone can do it but quite regulated. There is a place near Nottingham that does 50l of oxy and acetylene very cheap but a bit too far for me. So stuck with BOC for acetylene, at the last delivery the driver was moaning that they were getting very worried about their jobs as so many people were changing to rent free suppliers, he now has to pick up my empty oxygen and will not see him again for a while as we use a lot more oxygen for cutting. real shame you can't weld with propane.
